The nature of cold fusion (CF) is considered. It is supposed that the reaction of deuterons merger
takes place due to one deuteron, participating in the superfluidity motion, and one deuterons, not
participating in the superfluidity motion, participate in the reaction. The Coulomb barrier is
overcomed due to the kinetic energy of the Bose-condensate motion is very large. The Bosecondensate
forms from delocalized deuterons with taking into account that the effective mass of
delocalized deuterons is smaller than the free deuterons mass.

Review

Posits Bose-Einstein Condensate to overcome Coulomb barrier, energy is distributed among all atoms in the Condensate. Explains reaction rate and helium as product. Class with Kim and Takahashi.

Cold fusion wiki created

In response to an ugly situation on Wikiversity, which will be covered elsewhere on this blog, I have created a wiki, CFC, for the use of the cold fusion community and others, to read, create, edit, and critique studies and articles relating to cold fusion, and to coordinate activities. The cold fusion resource on Wikiversity, now exported to Wikiversity/Cold fusion on CFC,  is no longer accessible on Wikiversity, having been deleted in a way that makes it difficult for any reader to discover what happened and where the pages may be found.

A new argument on evap calorimetry

On LENR Forum, there is a thread on Shanahan’s critique of cold fusion experiments, and this post appeared by THHuxleynew:

I’ll give his last comment first:

PS – I don’t make these arguments often here, since I feel they are perhaps known by those interested in them, and strongly disliked by others. So I will not continue this argument unless new facts are added to make it worthwhile.

In fact, THH addresses an issue that I have never before seen raised. It is of limited impact, but it proposes a possible artifact that could afflict some experiments, that should probably be explicitly ruled out (or confirmed!)

Jed was arguing something familiar, common, and … incorrect, and THH nails that.

Jed,

It may help to look closely at the strands of argument here:

THH: As far as the F&P evidence against entrainment goes, salt measurement does not do the job since there can be condensation within the cell.
Jed: Yes, there is condensation in the cell. You can see it. But that does not change the heat balance.

I agree with Jed, he makes a number of true statements, but his point does not address mine. My point was that measuring salt balance does not determine the amount of entrainment, because entrained liquid can be either condensed (no salt) or non-evaporated (with salt). Condensation does not change the heat balance. But entrainment, in an open cell as we discussed here, does. Jed trying to argue that F&P can know there is no entrainment (and therefore no resulting change in heat balance) by measuring salt content. This is false.

He is correct. We will explain. Measuring the salt assumes that entrained liquid is unvaporized electrolyte, and the electrolyte is salty. However, that is not the only possibility!

Jed: Condensation is exothermic, so the heat lost to boiling is added back into the cell by condensation. You can test this by measuring the heat of vaporization in a cell with some condensation. It does not change from the textbook value. The null experiments by F&P all had condensation and they all produced the textbook value.

Jed is completely correct that condensation does not change the heat balance. However, this is missing THH’s point. The problem is not condensation alone, but condensation followed by entrainment of the condensed vapor (which would have no salt in it). The PF cell has a long, thin tube as a vent. if the vent is at a lower temperature than the cell interior, I would expect condensation to take place within it (heating it up).

This requires more than a little care to examine! It does seem possible that condensate (salt-free) could then be blown out of the cell. It would be, in boil-off cells close to the boiling point and would then evaporate outside the cell as it hits the unsaturated air. This water was not expelled as vapor, though, as it left the calorimetric envelope. If it is treated as having been vaporized, the heat of vaporization would then incorrectly enter the calculations.

And this cannot be ruled out by measuring the remaining salt. That would apply to “splash,” i.e., perhaps boiling or bubbling electrolyte that tosses it into the head space and then flow carries it out. The cell design militates against this as to any major quantity, but condensed electroyte might well be preferentially expelled. The devil is in the details.

The problem is that such results can be over-generalised. They only apply when conditions remain the same. The entrainment issue applies to unusual boil-off conditions. By definition the control, which does not have such extreme boil-off, will have different conditions, in a way likely to alter this result.

THH’s argument gets a bit iffy here. If the control is lacking an “extreme boil-off,” why? The point of the PF “simplicity” was that the boil-off time would be the experimental result. The loss of unevaporated water would indeed decrease the boil-off time, but only as an additional effect. That the boil-off is more rapid is a result, not a set condition. Presumably the conditions were set so that without XP, the boil-off times would be the same.

Jed: In a closed boiling cell with 100% condensation, the heat balance from vaporization is always zero. There is no heat lost to vaporization, because no vapor escapes.

I agree – but this is not relevant to the matter at hand which is discussion of F&P open cells in boil-off phase.

Both seem correct.

Jed: You are wrong about the salts,

I don’t believe you have shown that?

Jed often argues from conclusions based on evidence outside the argument. This then creates sprawling disagreements that never resolve. In this case, THH’s original point is very simple: the salt measurement does not definitely rule out liquid entrainment, liquid leaving the cell while unevaporated.

Jed: and you ignore the fact that they did several other tests to ensure there was no entrainment.

This is an offensive “you ignore” argument, common with trolls. Jed is not a troll, but … he’s not careful. He is very knowledgeable but has stated many times he doesn’t care about communicating clearly with skeptics. It’s unfortunate. Jed has paid his dues, to be sure, doing an incredible level of work to maintain the lenr-canr.org library (and he has been personally supportive to me in many ways). But we should keep him away from outreach to the mainstream! — Unless he is willing to develop better communication skills, dealing with genuine skeptics, and here, THH certainly resembles a genuine skeptic.

No – I point out that it is not possible to know which tests are done on which experiments, and note the danger of over-generalising results. That is addressing this fact, not ignoring it.

He is correct, and there are such dangers.

Jed: It would make no difference whether they did each of these tests every time: once every 10 tests would be fine. Note that they ran hundreds of cells, 16 at a time.

Only if the one in 10 included the (1 in 10 – I’m not sure?) cells that showed this special boil-off. We don’t know this.

This problem is addressed with random sampling and controls. I am not claiming Jed is wrong, only that his arguments are far less conclusive than he makes them out to be. Jed was correct, it is not necessary to verify every instance, but in doing that one would need to look out for possible sample bias.

THH is correct to at least suspect that rapid-boil-off cells would be more likely to entrain condensed water, which would again shorten the boil-off time. Obviously, one would want to see tests for expelled liquid, though that isn’t necessarily easy. I think measuring the heat of condensation on an external trap might be necessary. I’ve seen no descriptions of this.

THH is also not paying attention to the primary phenomenon, the rapid boil-off, treating it as an experimental condition, rather than a result. If there is the rapid boiloff changing the cell conditions, yes, entrained water could cause calorimetry error, but Pons and Fleischmann were not depending on the calorimetry at that point. The possible level of error could be estimated, and it is limited to the correction made to heat measurement for vaporized water. Looking at cell conditions, one could estimate the range of possible values.

Jed: They also tested closed boiling cells where the heat of vaporization plays no role (as I just said), and these cells also showed excess heat.

This kind of thinking fries my brain. Jed is arguing for the correctness of a conclusion (real heat, not artifact), which is the opposite of scientific process. There can be different artifacts in different experiments. What is needed is something that can be measured across all experiments, or at least most of them. We have that.

The heat/helium ratio. I remember when I started proposing measuring that with increased precision, there were arguments within the field that this was unnecessary, we already knew that helium was the ash.

However, if there is a single phenomenon that produces both heat and helium, in a consistent way, i.e., with a constant ratio, within experimental error, each measurement validates the other, again within the error bars. Ideally, helium should be measured in every D20 cold fusion experiment. At this point it’s too expensive, but that could change. It would kill all these arguments about various possible artifacts. If the heat/helium ratio holds in the experiment, the calorimetry was almost certainly correct, in spite of all the i’s not being dotted and the t’s crossed.

It has been pointed out that there is no end of possible artifacts, which is why the “they must be making some mistake” argument is so offensive. It’s pseudoscientific, proposing theory as creating a conviction of error. That makes sense when one must make some quick decision, but it makes no sense when one is examining experimental results to see if there are possible reasons to reconsider one’s beliefs.

(Cold fusion is not actually theoretically impossible, the arguments all require assuming a specific reaction and then calulating the rate for that reaction, which completely fails to be relevant if that is not the reaction.)

When Storms’ 2010 review was published in Naturwissenschafter, I winced when I saw the abstract: “reaction between two deuterons to make helium.” That was Storms opinion (generally rejecting multibody reactions, largely out of ignorance of the possibilities, and then thinking of two nuclei coming together, though, in fact, his theory is multibody, merely in a different way. It is not the simple two-body reaction that the abstract suggested.

That would be a different paper, with results and conditions we would need to look at afresh. Shanahan’s affect might be relevant here, or something else. Or perhaps this other sustem would be solid evidence. We would need to consider it. Either way, it does not change the arguments here relating to F&P open cell results.

Jed: Unless you have a scientific reason to believe there was entrainment, you should stop beating that dead horse. You have not given a single reason other than “maybe” “I suppose” “we can imagine” or “some scientists think they may eventually find a reason.”

This was way off. The explanation of how entrainment was ruled out was simply wrong. Testing the remaining salt does not show lack of liquid entrainment. I’m sure Jed can understand this, so, why not simply recognize that this particular argument has not — so far — been addressed.

That is where we disagree about the nature of skepticism. F&P posit some new effect (LENR) to explain anomalous results. It is they who must show there is no plausible mundane explanation – as they try to do – not others who must prove such an explanation.

Nevertheless, THH here takes on standard pseudoskeptical cant. “It is they who must show.” Must according to what? Someone can assert some evidence for something new, and can show evidence that they think supports it. There is no “must.” Both skeptics and believers fall into this trap. They become demanding, attached to a position, and the position of “wrong until proven true” or close equivalents, is pseudoskeptical. The moral imperative “must” deludes us. People need freedom to change their minds, we resist attempts to force us to accept based on coercive arguments. THH has the complete right to be skeptical, which is properly an agnostic position. He isn’t convinced yet, and he is the world’s foremost authority on whether or not he is convinced. Jed has the complete right to believe or accept whatever he wants … and to disbelieve skeptical arguments until and unless he is convinced.

The problem arises when one party or side attempts to claim the other is “wrong.” “Wrong” — like “Right” — is a complex judgment that does not exist in reality, and that gets into deeper ontology. The naive will think my statement preposterous!

Jed: Oh, and “condensation in a cell changes the heat of vaporization.” No, it doesn’t. Try it.

If THH said that, he misspoke. But I don’t think he said it. Rather this was Jed’s interpretation, and if so, the use of quotation marks was an error.

Condensation in the cell, as above, can affect open cell experiments by allowing entrainment not discovered from salt balance check.

This does not change the “heat of vaporization, which is a constant for a particular liquid. Rather it changes the correction made for vaporization, if and only if the liquid actually leaves the cell as a liquid, condensed, instead of as vapor. One would need to look at a particular experiment to see if this is relevant. I don’t think THH explained the problem well enough, I can see Jed continuing to think that it is the condensation that matters, and thus that THH is wrong wrong wrong. But that is not what THH is talking about. He is talking about the possibility of water leaving the cell as liquid instead of as vapor, having first been condensed inside and only then blown out. Thus the amount of water leaving the cell unvaporized would not be determined by measuring salt loss.

I don’t have the experience to say much more about this, about how much of an effect this might be. But I agree with THH on the primary issue, and it seems clear enough. Against this would only be argument from authority (they were experts and could not possibly make such a stupid mistake). Or other arguments that depend on there being a single effect without having actually shown that.

For closed cells we have other issues, and specifically, unless the calorimetry calibration is known independent of cell temperature distribution, ATER/CCS. But it does not help to mix up different cases – open and closed.

Each approach must be evaluated separately. Because of problems with confirmation bias and the file drawer effect, there are many problems in interpreting cold fusion experimental results. I remain satisfied as to the reality of the effect by the heat/helium reports, which actually point to a testable hypothesis, which has been confirmed by many, even though there is also room for improving the work, increasing precision, etc.

This is much more definitive than a pile of anecdotes, using varying experimental methods, showing heat but without being able to predict it. The multiplicity of excess heat reports is evidence, all right, but circumstantial. The correlation of conditions with results (such as loading ratio with heat) is supportive, but also subject to other possible interpretations. Heat/helium, by comparison, ices it.

We are discussing F&P’s open cell results. I’m not going to address directly here the question of whether condensation in the cell can ever affect the heat balance (by indirect means), it is not what I’m arguing now. Given more space we could however consider it. I’ve never stated or implied that condensation changes the heat of vaporisation.

Regards, THH

THH is the clearest, best, and most civil of all the skeptics I have encountered in about eight years of discussing cold fusion. He, and people like him, are important to the progress of cold fusion, more important than “believers,” unless the latter are scientists practicing real science, where the goal is to prove oneself wrong. (I.e., that the hypothesis fails to predict results). Those have paid their dues, and it is actually their work that is of ultimate importance, not their conclusions as such.

 

Spectacular news – IH support for basic research

Ahlfors typically provides teasers on LENR Forum. Here’s one, four images. I have not yet found the originals for other than the first, but, looking for the fourth led me to this:

Development of a System to Measure Trace Amounts of Helium in Air, Nitrogen, Hydrogen, or Deuterium

Malcolm Fowler. McFarland Instrumentation Services, Inc.
Thomas Claytor. High Mesa Technology
12th International Workshop on Anomalies in Hydrogen
Loaded Metals, 5-9 June 2017

Why is this such good news? That’s twofold. First, the only truly conclusive and very direct evidence that the FP Heat Effect is nuclear in nature is the heat/helium correlation. That work was first done and reported in 1991 by Miles, using order-of-magnitude helium measurements. The work was later confirmed with increased precision, but not the precision that is reported here, if I’m correct. They were working with 50 cc. samples, and if a decent sampling protocol can be developed and an analytical service is provided, this could drastically accelerate PdD cold fusion research.

The other news from the document:

We would like to acknowledge the continued support and encouragement for this work by:
Industrial Heat, LLC [address]
Mr. Thomas Francis Darden II, J.D., Manager, President, and Director
Mr. J.T. Vaughn, Vice President
Mr. Dewey Weaver

This is the support Industrial Heat has provided from the $50 million Woodford investment, obviously. This work is not being published for commercial purpose, this is for scientific progress, and the possible commercial value is very long-term.

Dewey Weaver is famous here as the inspiration for the Cold Fusion Community Official Watch-Weasel.

Now, I need to go out, but I intend to look for the other documents.

The source source of the first image: Claytor (1998).

As to the remainder, my guess it is from “Summary of Tritium Evolution from Various Deuterided Metals,” Thomas N. Claytor, Malcolm M. Fowler, Edmund K. Storms, Rick Cantwell, which is listed in Egely’s review of the June 2017 Asti Conference.

That is a very interesting list of authors! But I have not been able to find the paper yet. From Ahlfors’ quotation of the acknowledgements, this was also work supported by Industrial Heat, and from what little I’ve seen of it (from the Egely report and Ahlfors’ hint) this could also be of high interest. Congratulations to Industrial Heat for supporting productive research.

Ahlfors came back with his sources.

None of these are the paper I found mentioned in Infinite Energy. It is apparently the slide presentation for the talk (because I find it not easy to understand.) It’s hosted on the ISCMNS site. I had looked to see if I could find files in that directory, but the directory contents would not display without a filename. Those slides for it are shown by Ahlfors as hosted on lenr-canr.org, but it is not yet shown in the index. It is shown in the full listing of hosted files on lenr-canr.org.

In that directory I found a pdf with Claytor, Fowler, Cantwell and others as co-authors, also not yet in the lenr-canr.org library index. It does not have a date, but was given at a 2012 conference.

2:23 ● no recipe to both initiate and scale the effect exists. laboratory successes are won by trial and error, but a new idea is transforming understanding.
2:40 ● Dr. Edmund Storms is a nuclear chemist who has conducted many surveys of the field and [has] written two books from the signs and theories of LENR.
2:49 ● his experiments have shown that temperature is the single most important factor [in] regulating LENR excess heat and that high loading is not necessary to maintain a reaction in palladium deuterium systems.
3:00 ● he has put together the first physical science-based description of LENR utilizing the tiny nano spaces in materials as the nuclear active environment where hydrogen assembles to form a unique structure able to initiate nuclear fusion through resonance by a new and yet unknown atomic mechanism.

Dr. Storms:

3:22 ● we’ve spent 24 years proving to the ourselves first and then to the world that this is real. it’s a physically real phenomenon. now the problem is we have to convince ourselves and the world how and why it works. nothing about this violates conventional theory, it adds to it. this is a new undiscovered phenomenon.
4:02 ● It occurs in hot fusion very rapidly, the energy comes out in one big burst that is, let’s say, they’re deuterium, they come together momentarily and then they blow apart immediately in different combinations of neutrons and protons, carrying the energy with them, and the energy comes off instantaneously as energetic particles.
4:28 ● in cold fusion they come together very very slowly and the energy goes off as photons, gradually, as they get closer and closer together.
4:40 ● that’s the distinguishing characteristic and that’s what makes cold fusion truly unique as a nuclear reaction. that slow interaction is not the kind of interaction people have experienced in the past nor have much understanding of,  theoretically
4:57 ● the more ways in which Nature has to do something the easier it is to occur and the more often in nature. this occurs in nature very very seldom, and it’s very very difficult to duplicate and so therefore it must be something fairly rare and therefore very unique and therefore I’ve said that it really only has one way of doing this and unless you have precisely that arrangement, that Nuclear Active Environment, it’s not going to happen.
5:29 ● LENR requires the significant change in the material to occur, and getting that change in the material has been the real big problem to make this effect reproducible.
5:40 ● right now we’re creating that environment by accident, we threw a bunch of stuff together, a few places at random happen to have the right combination of materials and relationships to work.
5:52 ● so most of the samples … maybe less than 1% are active.
5:57 ● the effect has not occurred throughout the sample. It only occurs in special very rare,  randomly created regions in the sample. I call this a nuclear active environment.
6:07 ● presumably the more of the sites are present the more energy we will be able to make.


Figure 8. Histogram of power production vs. the number of reported values. A probability function, shown as the dashed line, is used to fit the data to bins at 10 W intervals. (Storms, 2016)

6:14 ● [pointing to Figure 8] these samples [on the left] would have had only a few of these active sites and these samples [on the right] would have had a large number of that. this assembles as a  probability distribution showing that the probability of having a large number of sites were very low and the probability of having a few sites were very high and, of course, zero having a very high probability that’s why it’s been very difficult to reproduce.
6:42 ● I assume that something changes within the material and I call that change the creation of the nuclear active environment. it has to be something that is universally present in all the experiments that work, no matter what method is used, no matter what material is used,  or whether it’s light hydrogen or heavy hydrogen.
7:02 ● now, what are the characteristics of the nuclear active environment? we know a few of them. we know that you have to have deuterium or hydrogen in that environment. we know that the higher the concentration in that environment, the faster the reaction goes. we know that something in that environment is capable of hiding the Coulomb barrier of hydrogen or deuterium. we know that something in that environment also is able to communicate the energy to the lattice rather than have it go off as energetic particles, so we know, just from the way at which it behaves, certain overall characteristics, but we don’t know the details yet, but when I say, okay, let’s talk about the nuclear active environment, I’m saying, let’s talk about where those details are located in the material.
7:54 ● we want to look where we expect that material to be located. I expect it to be located on the surface. the challenge is to figure out what about the surface is universally related to a sample that makes excess energy.
8:10 ● all except for the last few microns of the surface is totally dead. so all you need is a few microns of palladium on something else and I put a few microns on platinum, it works just well as a solid piece.
8:29 ● but after examining hundreds of these photomicrographs by other people or by myself, the only thing I would see was common to all experimental methods and experimental conditions were cracks.
8:42 ●  in hot fusion, you overcome the Coulomb barrier by brute force, using high-energy, and in cold fusion you overcome it by lowering the Coulomb barrier using electric charge.
8:58 ●  you have to have a condition in which the electric charge is suitably large, and cracks have the potential to produce that kind of condition.
9:07 ● that seems crazy because for a long time people felt that cracks were bad. they allow the deuterium to leak out of the palladium.
9:17 ● we see that happen because if you put some of this material that has the cracks in it in a liquid, you can see the bubbles of hydrogen coming out of those cracks. so they were ignored or people were trying to avoid them.
9:34 ● what I propose is that the crack has to have a particular size, and when it has that size, it allows the nuclei of deuterons or protons to come into that and set up a series of, say,  proton-electron-proton-electron, with the electrons between each of the nuclei, thus hiding or reducing the Coulomb barrier
10:02 ● the size of the crack is something that ought to be determined. it has to be small enough that they would not allow the hydrogen molecule to penetrate because we know the hydrogen molecule does not produce a nuclear reaction. they have to be big enough that a single nucleus of hydrogen can go in there and be retained and not interact with it chemically.
10:28 ● so I’m guessing something less than 10 nanometers. cracks always start small. cracks always start at the size that would be nuclear active, but only for a short time.
10:48 ● holes themselves are not active. they only give you the indication that that stress reorganized the surface.
11:02 ● what I’m saying is that stress also produced the nanocracks in the walls these holes, and that’s where you have the look to find the genie of cold fusion.

Ruby Carat:

11:14 ● the nuclear active environment is proposed to be a nano-sized gap that hosts a unique form of hydrogen. while large spaces in cracks allow hydrogen to escape the material, tiny nano sized gaps are small enough to retain [a] single nuclei of hydrogen in a covalent chain called a hydroton. subjected to the high concentration of negative charge in the walls, the electrons shared by the hydrogen nuclei are forced into a more compact state with an average smaller distance between nuclei. but what happens to create a nuclear reaction?

Dr. Storms

11:55 ●  whatever it is has the ability to initiate a number of different kinds of reactions. one makes helium, heat, and makes tritium, another transmutation, so there’s a variety of things that can happen in that environment.
12:12 ● all LENR behavior using istotopes of hydrogen can be explained by a single basic mechanism  operating in a single nuclear active environment. That would be a lot to expect.


12:21 ● for something so unusual for this to have a variety of ways in which it can happen… by sheer probability — chance — there’s a crack formed and it has to have the right size, and then because of diffusion they [hydrogen nuclei] start building up a concentration in the crack.
12:39 ● hydrogen once it gets into this gap forms a covalent chain, which I call a hydroton, which releases Gibbs energy and that stabilizes the gap.
12:50 ● the hydrogen can form a chemical compound that has lower energy than any hydrogen anywhere else in the material so the hydrogen migrates there, forms this compound, and because that compound is more stable than any other it cannot decompose without that
energy being reapplied to the hydrogen, in order to get it out of there. because that is occurring in the chemical lattice it follows all the rules of a chemical reaction.
13:22 ● that narrow crack would have a very high concentration of negative charge on both walls which would force the hydrogen into a structure that I believe would help hide the Coulomb barrier and would help the resonance process take place.
13:44 ● once that builds up to a sufficient number something triggers it. that can just be the normal temperature vibrations because everything at the atomic level is vibrating, but because it has a linear structure it can start to vibrate such that these two come together, these apart,  these come together and so forth. so these things start to vibrate in line.
14:09 ● and when they do, because you have charges moving, you have the prospect of photons being generated.
14:19 ● these two come together they find themselves too close, they have too much energy, too much mass for the distance because they’re all the way to having formed a fusion product. now the system knows that if it collapses, if it comes  closer together it will gain energy because the end product is a nuclear product that has less mass than the sum total so it knows that that’s the direction to go
14:51 ● so it just keeps giving off photons. finally enough are given off and it’s time to get a little closer, and they give off a little bigger photon. each time it gives up a photon it collapses a little more, a little more, a little more, meanwhile vibrating, photons are streaming out, finally the last photon, goes off and it becomes a deuteron, because the electron that was between them gets sucked into a final product.
15:18 ● there’s hardly any mass-energy left over at that point so this becomes stable, or if not, gives off a very weak gamma.
15:28 ● now the deuteron, if there happens to be another proton or another deuteron in there, it can start the process all over again. if another deuteron happens to be there, then it can make helium, or if a proton happens to be there it will make tritium. The deuterium has a choice, it can diffuse out, in which case it will be replaced by a proton, more likely, because that’s what’s in the general environment, or it can stay there and another proton comes in and that, starts to fuse, and it makes tritium instead.
16:03 ● it is symmetrical, it isn’t just when they’re bounced in this direction they give off a photon, when they bounce in [the other] direction they give off a photon also.  these things are bouncing in a symmetrical way.
16:12 ● each time they go this direction, they lose mass and then they come back together and lose mass. at some point they’ve lost enough that these two guys don’t bounce and stick together and then these two guys over here stick together and so the question is, where during that process do they recognize that they have too much mass and have to get rid of [it]? when you do it by hot fusion that’s done very very quickly and overwhelms this process
16:37 ● I’m proposing that this is the unique feature of cold fusion. this is where cold  fusion differs from hot fusion.
16:46 ●  cold fusion is slow, it’s methodical. because it occurs over a period of time, the energy has time to get out in small quanta.
16:59 ● that electron has to have very special properties and that’s the only thing that is novel. this is total consistent normal physics except for that electron and its characteristics.
17:11 ● something new has happened, has been discovered and is required to make cold fusion work. the crack is not destroyed. the crack is a manufacturing tool it’s just simply there and atoms go in, fuse, end products diffuse  out, maybe, or they stay there, more stuff fuses. It’s an assembly line of the fusion process. that crack becomes attractive. and it’s also attractive because it’s very difficult to produce and it’s outside of the thermodynamic characteristics of a material. in other words, cracks can occur in any material regardless of its thermodynamic properties.

Ruby Carat

18:00 ● nano spaces allow a different form of atomic interaction to occur where hydrogen nuclei and electrons can form a chain called a hydroton.
18:12 ● pulsing in resonance periodically smaller distances coax nuclei into a slow fusion process where smaller bits of mass convert to energy through coherent photon emission. an electron is absorbed to make the final product. all the isotopes of hydrogen are proposed to behave the same way. any other element in the gap resonates to transmutation.

Dr. Storms

18:40 ● that’s why cold fusion was essentially rejected by people who were educated and had experience with hot fusion, which plays by entirely different rules. cold fusion plays by rules that we don’t presently understand and those rules involve slow interaction and a slow release of energy. I also say that cold fusion has to follow all the laws of nature as we presently know and love them.
19:09 ● they cannot violate any law of nature, chemical or physical. the only problem is if there’s something missing in those laws, so it isn’t that they’re conflicting with anything. it’s just that we don’t have all the pieces yet. that’s the the big, what I call the big discovery, that a chemical compound of hydrogen created under very special circumstances can then fuse.

Ruby Carat

19:37 ● nanogaps and hydrotons are able to explain the broad variety of evidence in LENR experiments by reasoning that follows the data and begins with tritium production.

Dr. Storms

20:00 ● tritium provides the key to understanding this process and tritium also provides the way which the process can be verified. tritium is made in cold fusion cells. but the tritium cannot be made by the hot fusion reaction because we’re not seeing any neutrons, so it has to be made by some other process.
20:22 ● well, there are a limited number of ways in which you can make tritium. when you examine all those, you discover that the only thing that really makes any sense is this reaction here: the deuteron fuses with a proton, captures the electron, makes tritium, which then decays by its normal behavior, with a half-life of 12.3 years, to helium-3 and an electron.
20:43 ● all of the hydrogen isotopes happen to behave the same way because that’s the only way you can get tritium. then it’s also the only way you can get helium. the electron also has to be sucked in. the deuteron does this with the electron, that makes hydrogen-4 which decays very very rapidly so we don’t see that accumulate, to make helium-4 and, of course, the electron as part of the decay.
21:12 ● hydrogen-4 does not decay normally into helium-4 and, but it has to, for the cold fusion thing to work, because if this is an exception, if the electron doesn’t get sucked in, then my whole model starts to fall apart because where the heck does that electron go? it has to be there in order to hide the Coulomb barrier. it sits there in the other two reactions, so why isn’t it there in the helium? so right there, normal nuclear expectations break down,
21:46 ● hydroton is a whole new world that now cold fusion and Pons and Fleischmann have revealed exists. it was totally invisible until they came along and said, hey wait a minute, here’s something that can only work if the rules change, and so better start looking at new rules, and the hydroton is, in fact, the structure that makes those rules operate.
22:13 ● I’m taking these various ideas — many of them are not original to me, what is original is the putting together so that they have a logical relationship, and then, on the basis of that relationship, they can predict precisely what’s going to happen…. there’s no wiggle room in this theory. I mean I’m not like most theoreticians, “okay if that doesn’t work I can adjust some of the parameters here and make it work.” no, it is either right or wrong. it’s easy, simple as that, I even go down in flames or I’m right, and the result is that suddenly I can make sense of cold fusion, and suddenly now I know how to make it reproducible, and once it works I know how to engineer it.  so you know what? problem is I haven’t yet proven that.

Ruby Carat

23:07 ● beginning with experimental facts and following a logical process of reasoning has produced both questions that challenge the standard model of nuclear physics and provided testable predictions that will confirm or deny the nanogap hydroton hypothesis.

Dr. Storms

23:26 ● I predict that the hydroton is metallic hydrogen. this is that mythical material that people have been looking for by squeezing higher than at very high pressure. that is precisely what is formed in this gap. the gap makes that possible.
23:41 ● the reason why metallic hydrogen is been very difficult to detect is because once it forms, it fuses. that allows us to harvest the mathematical understanding of metallic hydrogen, which is already in the literature, to explain this material, and also will lead to another kind of measurement.
24:02 ● cold fusion represents a whole new way of looking at nuclear interaction, the rules of which will have other implications, that will have other applications and will allow us to do things that we can’t even suspect to be done now, including the deactivation of radioactive material we have generated by virtue of the other energy sources.

Figure 13. Relative rates of formation for deuterium, helium, and tritium as a function of d/(p+d) in the NAE. The figure approximates ideal behavior when the concentration of NAE and temperature are constant. Unknown influences are expected to slightly modify the relationship. The concentration of p is 100% in the metal on the left side of the figure and d has a concentration of 100% on the right side. (Storms, 2016.)

24:33 ● only experimental results will validate the hypotheses of the nanogap hydroton model. new data supports the hydroton prediction that the amount of tritium is related to the deuterium to protium ratio  in the fuel, to confirm the nuclear active environment as the nanogap, creating the right size nanospace that hosts the reaction, with 100% reliability, is crucial. determining if light hydrogen systems are producing tritium is an important next step.
25:08 ● laboratory evidence that identifies emitted photons as coming from a particular reaction would be defining for the hydrogen model.
25:23 ● cold fusion technology will be a radically different type of power creating a paradigm shift in global operations. a mere one cubic kilometer of ocean water contains fusion energy equal to all the world’s oil reserves and the nano-sized source of power holds the promise of a defining next step in our human evolution.
25:48 ● what we have to do is find a way of encouraging a material to create that structure in the presence of hydrogen. doesn’t do any good to try to create it in the absence of hydrogen because in the absence of hydrogen the crack will just simply continue to grow and if you put hydrogen in later its to big, it’s no longer nuclear active, so you have to have the hydrogen present simultaneously with the formation of the crack structure, and that’s the secret of the process
26:22 ● you have to have these two things happen simultaneously well it’s like opening a window and you open a little bit and you see a little bit of what’s outside, and it looks really interesting, you open a little bit more and then all of a sudden you realize wow there’s a whole new world out there. and so this theory has opened that world into a way of looking at cold fusion that hasn’t really been explored in completion. my guess is that once we understand how it works we will find some other metal or some alloy or maybe an alloy of palladium and nickel and some combination of deuterium and hydrogen that will be even better than what we presently have. we are nowhere near the ideal at this point.

things. there are the things that, you know, a hundred graduate students will work on for twenty years to really master and understand, and they’ll give the details of this mechanism going on, and they’ll generate the Nobel Prizes that everybody will be really happy about, understanding this physics better.

What is scientific consensus?

Cold fusion debates often assert that there is this or that scientific consensus. What would this mean?

https://www.merriam-webster.com/dictionary/consensus

1 a : general agreement : unanimity • the consensus of their opinion, based on reports … from the border — John Hersey
b : the judgment arrived at by most of those concerned the consensus was to go ahead
2 : group solidarity in sentiment and belief

So what, then, is scientific consensus? Because consensus is about opinion or judgment, there must be someone with opinions or judgments. Who?

Well, “scientists,” of course! Just any scientist? Continue reading “What is scientific consensus?”

Transcript at Storms 2017 video transcript.

Comments welcome. My commentary will be added.

This is an excellent video explaining Storms’ theory. Ruby, at the beginning, treats cold fusion as a known thing (i.e., will provide energy for a very long time, etc.) — but that’s her job, political. Cold Fusion Now is an advocacy organization.

Our purpose here, to empower the community of interest in cold fusion, can dovetail with that, but we include — and invite — skeptical points of view.

As to cold fusion theory, there is little agreement in the field. Criticism of theory by other theoreticians and those capable of understanding the theories is rare, for historical reasons. We intend to move beyond that limitation, self-imposed as a defensive reaction to the rejection cascade. It’s time.

For cold fusion to move forward we must include and respect skepticism, just as most of us want to see the mainstream include and respect cold fusion as a legitimate research area.

At this point, I intend to put together a review of the video, which first requires a transcript. Anyone could make such a thing. If a reader would like to contribute, I’d ask that references be included to the video elapsed time (where a section begins) … though this could also be added later. Every contribution matters and takes us into the future.

I have done things like this myself, in the past, and I always learned a great deal by paying attention to detail like that, detail without judgment, just what was actually said. So I’m inviting someone else to benefit in this way. Let me know!

(I did make a transcript, then checked my email a day late and found Ruby Carat had sent me one….)

(There is a “partial” transcript here. I’ll be looking at that. If someone wants to check or complete it, that would be useful.)

Abstract

We reply here to the critique by Douglas Morrison [1] of our paper [2] which was recently
published in this Journal. Apart from his general classification of our experiments into stages 1-
5, we find that the comments made [1] are either irrelevant or inaccurate or both.

In the article “Comments on Claims of Excess Enthalpy by Fleishmann and Pons using simple
cells made to Boil” Douglas Morrison presents a critique [1] of the paper “Calorimetry of the Pd-
D2O system: from simplicity via complications to simplicity” which has recently been published
in this Journal [2]. In the introduction to his critique, Douglas Morrison has divided the timescale
of the experiments we reported into 5 stages. In this reply, we will divide our comments
into the same 5 parts. However, we note at the outset that Douglas Morrison has restricted his
critique to those aspects of our own paper which are relevant to the generation of high levels of
the specific excess enthalpy in Pd-cathodes polarized in D2O solutions i.e. to stages 3-5. By
omitting stages 1 and 2, Douglas Morrison has ignored one of the most important aspects of our
paper and this, in turn, leads him to make several erroneous statements. We therefore start our
reply by drawing attention to these omissions in Douglas Morrison’s critique.

Stages 1 and 2

In the initial stage of these experiments the electrodes (0.2mm diameter x
12.5mm length Pd-cathodes) were first polarised at 0.2A, the current being raised to 0.5A in
stage 2 of the experiments.

We note at the outset that Douglas Morrison has not drawn attention to the all important “blank
experiments” illustrated in Figs 4 and 6 or our paper by the example of a Pt cathode polarised in
the identical 0.1M LiOD electrolyte. By ignoring this part of the paper he has failed to
understand that one can obtain a precise calibration of the cells (relative standard deviation
0.17%) in a simple way using what we have termed the “lower bound heat transfer coefficient,
(kR’)11”, based on the assumption that there is zero excess enthalpy generation in such “blank
cells”. We have shown that the accuracy of this value is within 1 sigma of the precision of the
true value of the heat transfer coefficient, (kR’)2, obtained by a simple independent calibration
using a resistive Joule heater. Further methods of analysis [3] (beyond the scope of the particular
paper [2]) show that the precision of (kR’)11 is also close to the accuracy of this heat transfer
coefficient (see our discussion of stage 3).

We draw attention to the fact that the time-dependence of (kR’)11, (the simplest possible way of
characterising the cells) when applied to measurements for Pd-cathodes polarised in D2O
solutions, gives direct evidence for the generation of excess enthalpy in these systems. It is quite
unnecessary to use complicated methods of data analysis to demonstrate this fact in a semiquantitative
fashion.

Stage 3 Calculations

Douglas Morrison starts by asserting: “Firstly, a complicated non-linear
regression analysis is employed to allow a claim of excess enthalpy to be made”. He has failed
to observe that we manifestly have not used this technique in this paper [2], the aim of which has
been to show that the simplest methods of data analysis are quite sufficient to demonstrate the
excess enthalpy generation. The only point at which we made reference to the use of non-linear
regression fitting (a technique which we used in our early work [4]) was in the section dealing
with the accuracy of the lower bound heat transfer coefficient, (kR’)11, determined for “blank
experiments” using Pt-cathodes polarised in D2O solutions. At that point we stated that the
accuracy of the determination of the coefficient (kR’)2 (relative standard deviation ~1.4% for the
example illustrated [2]), can be improved so as to be better than the precision of (kR’)11 by using
non-linear regression fitting; we have designated the values of (kR’) determined by non-linear
regression fitting by (kR’)5. The values of (kR’)5 obtained show that the precision of the lower
bound heat transfer coefficient (kR’)11 for “blank experiments” can indeed be taken as a measure
of the accuracy of (kR’). For the particular example illustrated the relative standard deviation was
~ 0.17% of the mean. It follows that the calibration of the cells using such simple means can be
expected to give calorimetric data having an accuracy set by this relative standard deviation in
the subsequent application of these cells.

We note here that we introduced the particular method of non-linear regression fitting (of the
numerical integral of the differential equation representing the model of the calorimeter to the
experimental data) for three reasons: firstly, because we believe that it is the most accurate single
method (experience in the field of chemical kinetics teaches us that this is the case); secondly,
because it avoids introducing any personal bias in the data treatment; thirdly, because it leads to
direct estimates of the standard deviations of all the derived values from the diagonal elements of
the error matrix. However, our experience in the intervening years has shown us that the use of
this method is a case of “overkill”: it is perfectly sufficient to use simpler methods such as multilinear
regression fitting if one aims for high accuracy. This is a topic which we will discuss
elsewhere [3]. For the present, we point out again that the purpose of our recent paper [2] was to
illustrate that the simplest possible techniques can be used to illustrate the generation of excess
enthalpy. It was for this reason that we chose the title: “Calorimetry of the Pd-D2O system: from
simplicity via complications to simplicity”.
Douglas Morrison ignores such considerations because his purpose evidently is to introduce a
critique of our work which has been published by the group at General Electric [5]. We will
show below that this critique is totally irrelevant to the recent paper published in this Journal [2].
However, as Douglas Morrison has raised the question of the critique published by General
Electric, we would like to point out once again that we have no dispute regarding the particular
method of data analysis favoured by that group [5]: their analysis is in fact based on the heat
transfer coefficient (kR’)2. If there was an area of dispute, then this was due solely to the fact that
Wilson et al introduced a subtraction of an energy term which had already been allowed for in
our own data analysis, i.e. they made a “double subtraction error”. By doing this they derived
heat transfer coefficients which showed that the cells were operating endothermically, i.e. as
refrigerators! Needless to say, such a situation contravenes the Second Law of Thermodynamics
as the entropy changes have already been taken into account by using the thermoneutral potential
of the cells.
We will leave others to judge whether our reply [6] to the critique by the group at General
Electric [5] did or did not “address the main questions posed by Wilson et al.” (in the words of
Douglas Morrison). However, as we have noted above the critique produced byWilson et al [5]
is in any event irrelevant to the evaluations presented in our paper in this journal [2]: we have
used the self-same method advocated by that group to derive the values of the excess enthalpy
given in our paper. We therefore come to a most important question: “given that Douglas
Morrison accepts the methods advocated by the group at General Electric and, given that we
have used the same methods in the recent publication [2] should he not have accepted the
validity of the derived values?”

Stage 4 Calculation

Douglas Morrison first of all raises the question whether parts of the cell contents may have been expelled as droplets during the later stages of intense heating. This is readily answered by titrating the residual cell contents: based on our earlier work about 95% of the residual lithium deuteroxide is recovered; some is undoubtedly lost in the reaction of this “aggressive” species with the glass components to form residues which cannot be titrated.

Furthermore, we have found that the total amounts of D2O added to the cells (in some cases over
periods of several months) correspond precisely to the amounts predicted to be evolved by (a)
evaporation of D2O at the instantaneous atmospheric pressures and (b) by electrolysis of D2O to
form D2 and O2 at the appropriate currents; this balance can be maintained even at temperatures
in excess of 90 degrees C [7]

We note here that other research groups (eg [5]) have reported that some Li can be detected
outside the cell using atomic absorption spectroscopy. This analytic technique is so sensitive
that it will undoubtedly detect the expulsion of small quantities of electrolyte in the vapour
stream. We also draw attention to the fact that D2O bought from many suppliers contains
surfactants. These are added to facilitate the filling of NMR sample tubes and are difficult
(probably impossible) to remove by normal methods of purification. There will undoubtedly be
excessive foaming (and expulsion of foam from the cells) if D2O from such sources is used. We
recommend the routine screening of the sources of D2O and of the cell contents using NMR
techniques. The primary reason for such routine screening is to check on the H2O content of the
electrolytes.

Secondly, Douglas Morrison raises the question of the influence of A.C. components of the
current, an issue which has been referred to before and which we have previously answered [4].
It appears that Douglas Morrison does not appreciate the primary physics of power dissipation
from a constant current source controlled by negative feedback. Our methodology is exactly the
same as that which we have described previously [4]; it should be noted in addition that we have
always taken special steps to prevent oscillations in the galvanostats. As the cell voltages are
measured using fast sample-and-hold systems, the product (Ecell – Ethermoneutral, bath)I will give the mean enthalpy input to the cells: the A.C. component is therefore determined by the ripple
content of the current which is 0.04%.

In his third point on this section, Douglas Morrison appears to be re-establishing the transition
from nucleate to film boiling based on his experience of the use of bubble chambers. This
transition is a well-understood phenomenon in the field of heat transfer engineering. A careful
reading of our paper [2] will show that we have addressed this question and that we have pointed
out that the transition from nucleate to film boiling can be extended to 1-10kW cm-2 in the
presence of electrolytic gas evolution.

Fourthly and for good measure, Douglas Morrison once again introduces the question of the
effect of a putative catalytic recombination of oxygen and deuterium (notwithstanding the fact
that this has repeatedly been shown to be absent). We refer to this question in the next section;
here we note that the maximum conceivable total rate of heat generation (~ 5mW for the
electrode dimensions used) will be reduced because intense D2 evolution and D2O evaporation
degasses the oxygen from the solution in the vicinity of the cathode; furthermore, D2 cannot be
oxidised at the oxide coated Pt-anode. We note furthermore that the maximum localised effect
will be observed when the density of the putative “hot spots” will be 1/delta2 where delta is the
thickness of the boundary layer. This gives us a maximum localised rate of heating of ~ 6nW.
The effects of such localised hot spots will be negligible because the flow of heat in the metal
(and the solution) is governed by Laplace’s Equation (here Fourier’s Law). The spherical
symmetry of the field ensures that the temperature perturbations are eliminated (compare the
elimination of the electrical contact resistance of two plates touching at a small number of
points).

We believe that the onus is on Douglas Morrison to devise models which would have to be
taken seriously and which are capable of being subjected to quantitative analysis. Statements of
the kind which he has made belong to the category of “arm waving”.

Stage 5 Effects

In this section we are given a good illustration of Douglas Morrison’s selective
and biased reporting. His description of this stage of the experiments starts with an incomplete
quotation of a single sentence in our paper. The full sentence reads:

“We also draw attention to some further important features: provided satisfactory electrode
materials are used, the reproducibility of the experiments is high; following the boiling to
dryness and the open-circuiting of the cells, the cells nevertheless remain at a high temperature
for prolonged periods of time (fig 11); furthermore the Kel-F supports of the electrodes at the
base of the cells melt so that the local temperature must exceed 300 degrees C”.

Douglas Morrison translates this to: “Following boiling to dryness and the open-circuiting of
the cells, the cells nevertheless remain at high temperature for prolonged periods of time;
furthermore the Kel-F supports of the electrodes at the base of the cells melt so that the local
temperature must exceed 300 degrees C”.

Readers will observe that the most important part of the sentence, which we have underlined, is
omitted; we have italicised the words “satisfactory electrode materials” because that is the nub of
the problem. In common with the experience of other research groups, we have had numerous
experiments in which we have observed zero excess enthalpy generation. The major cause
appears to be the cracking of the electrodes, a phenomenon which we will discuss elsewhere.
With respect to his own quotation Douglas Morrison goes on to say: “No explanation is given
and fig 10 is marked ‘cell remains hot, excess heat unknown'”. The reason why we refrained
from speculation about the phenomena at this stage of the work is precisely because explanations
are just that: speculations. Much further work is required before the effects referred to can be
explained in a quantitative fashion. Douglas Morrison has no such inhibitions, we believe
mainly because in the lengthy section Stage 5 Effects he wishes to disinter “the cigarette lighter
effect”. This phenomenon (the combustion of hydrogen stored in palladium when this is exposed
to the atmosphere) was first proposed by Kreysa et al [8] to explain one of our early
observations: the vapourisation of a large quantity of D2O (~ 500ml) by a 1cm cube palladium
cathode followed by the melting of the cathode and parts of the cell components and destruction
of a section of the fume cupboard housing the experiment [9]. Douglas Morrison (in common
with other critics of “Cold Fusion”) is much attached to such “Chemical Explanations” of the
“Cold Fusion” phenomena. As this particular explanation has been raised by Douglas Morrison,
we examine it here.

In the first place we note that the explanation of Kreysa et al [8] could not possibly have
applied to the experiment in question: the vapourisation of the D2O alone would have required
~1.1MJ of energy whereas the combustion of all the D in the palladium would at most have
produced ~ 650J (assuming that the D/Pd ratio had reached ~1 in the cathode), a discrepancy of a
factor of ~ 1700. In the second place, the timescale of the explanation is impossible: the
diffusional relaxation time is ~ 29 days whereas the phenomenon took at most ~ 6 hours (we
have based this diffusional relaxation time on the value of the diffusion coefficient in the alphaphase;
the processes of phase transformation coupled to diffusion are much slower in the fully
formed Pd-D system with a corresponding increase of the diffusional relaxation time for the
removal of D from the lattice). Thirdly, Kreysa et al [8] confused the notion of power (Watts)
with that of energy (Joules) which is again an error which has been promulgated by critics
seeking “Chemical Explanations” of “Cold Fusion”. Thus Douglas Morrison reiterates the notion
of heat flow, no doubt in order to seek an explanation of the high levels of excess enthalpy
during Stage 4 of the experiments. We observe that at a heat flow of 144.5W (corresponding to
the rate of excess enthalpy generation in the experiment discussed in our paper [2] the total
combustion of all the D in the cathode would be completed in ~ 4.5s, not the 600s of the duration
of this stage. Needless to say, the D in the lattice could not reach the surface in that time (the
diffusional relaxation time is ~ 105s) while the rate of diffusion of oxygen through the boundary
layer could lead at most to a rate of generation of excess enthalpy of ~ 5mW.

Douglas Morrison next asserts that no evidence has been presented in the paper about stages
three or four using H2O in place of D2O. As has already been pointed out above he has failed to
comment on the extensive discussion in our paper of a “blank experiment”. Admittedly, the
evidence was restricted to stages 1 and 2 of his own classification but a reference to an
independent review of our own work [10] will show him and interested readers that such cells
stay in thermal balance to at least 90 degrees C (we note that Douglas Morrison was present at
the Second Annual Conference on Cold Fusion). We find statements of the kind made by
Douglas Morrison distasteful. Have scientists now abandoned the notion of verifying their facts
before rushing into print?

In the last paragraph of this section Douglas Morrison finally “boxes himself into a corner”:
having set up an unlikely and unworkable scenario he finds that this cannot explain Stage 5 of
the experiment. In the normal course of events this should have led him to: (i) enquire of us
whether the particular experiment is typical of such cells; (ii) to revise his own scenario. Instead,
he implies that our experiment is incorrect, a view which he apparently shares with Tom Droege
[11]. However, an experimental observation is just that: an experimental observation. The fact
that cells containing palladium and palladium alloy cathodes polarised in D2O solutions stay at
high temperatures after they have been driven to such extremes of excess enthalpy generation
does not present us with any difficulties. It is certainly possible to choose conditions which also
lead to “boiling to dryness” in “blank cells” but such cells cool down immediately after such
“boiling to dryness”. If there are any difficulties in our observations, then these are surely in the
province of those seeking explanations in terms of “Chemical Effects” for “Cold Fusion”. It is
certainly true that the heat transfer coefficient for cells filled with gas (N2) stay close to those for
cells filled with 0.1M Li0D (this is not surprising because the main thermal impedance is across
the vacuum gap of the Dewar-type cells). The “dry cell” must therefore have generated ~120kJ
during the period at which it remained at high temperature (or ~ 3MJcm-3 or 26MJ(mol Pd)-1).
We refrained from discussing this stage of the experiments because the cells and procedures we
have used are not well suited for making quantitative measurements in this region. Inevitably,
therefore, interpretations are speculative. There is no doubt, however, that Stage 5 is probably
the most interesting part of the experiments in that it points towards new systems which merit
investigation. Suffice it to say that energies in the range observed are not within the realm of any
chemical explanations.
We do, however, feel that it is justified to conclude with a further comment at this point in
time. Afficionados of the field of “Hot Fusion” will realise that there is a large release of excess
energy during Stage 5 at zero energy input. The system is therefore operating under conditions
which are described as “Ignition” in “Hot Fusion”. It appears to us therefore that these types of
systems not only “merit investigation” (as we have stated in the last paragraph) but, more
correctly, “merit frantic investigation”.

Douglas Morrison’s Section “Conclusions” and some General Comments

In his section entitled “Conclusions”, Douglas Morrison shows yet again that he does not
understand the nature of our experimental techniques, procedures and methods of data evaluation
(or, perhaps, that he chooses to misunderstand these?). Furthermore, he fails to appreciate that
some of his own recommendations regarding the experiment design would effectively preclude
the observation of high levels of excess enthalpy. We illustrate these shortcomings with a
number of examples:

(i) Douglas Morrison asserts that accurate calorimetry requires the use of three thermal
impedances in series and that we do not follow this practice. In point of fact we do have three
impedances in series: from the room housing the experiments to a heat sink (with two
independent controllers to thermostat the room itself); from the thermostat tanks to the room
(and, for good measure, from the thermostat tanks to further thermostatically controlled sinks);
finally, from the cells to the thermostat tanks. In this way, we are able to maintain 64
experiments at reasonable cost at any one time (typically two separate five-factor experiments).

(ii) It is naturally essential to measure the heat flow at one of these thermal impedances and we
follow the normal convention of doing this at the innermost surface (we could hardly do
otherwise with our particular experiment design!). In our calorimeters, this thermal impedance is
the vacuum gap of the Dewar vessels which ensures high stability of the heat transfer
coefficients. The silvering of the top section of the Dewars (see Fig 2 of our paper [2] further
ensures that the heat transfer coefficients are virtually independent of the level of electrolyte in
the cells.

(iii) Douglas Morrison suggests that we should use isothermal calorimetry and that, in some
magical fashion, isothermal calorimeters do not require calibration. We do not understand: how
he can entertain such a notion? All calorimeters require calibration and this is normally done by
using an electrical resistive heater (following the practice introduced by Joule himself). Needless
to say, we use the same method. We observe that in many types of calorimeter, the nature of the
correction terms are “hidden” by the method of calibration. Of course, we could follow the selfsame
practice but we choose to allow for some of these terms explicitly. For example, we allow
for the enthalpy of evaporation of the D2O. We do this because we are interested in the operation
of the systems under extreme conditions (including “boiling”) where solvent evaporation
becomes the dominant form of heat transfer (it would not be sensible to include the dominant
term into a correction).

(iv) There is, however, one important aspect which is related to (iii) i.e. the need to calibrate the
calorimeters. If one chooses to measure the lower bound of the heat transfer coefficient (as we
have done in part of the paper published recently in this journal [2]) then there is no need to carry
out any calibrations nor to make corrections. It is then quite sufficient to investigate the time
dependence of this lower bound heat transfer coefficient in order to show that there is a
generation of excess enthalpy for the Pd-D2O system whereas there is no such generation for
appropriate blanks (e.g. Pt-D2O or Pd-H2O). Alternatively, one can use the maximum value of
the lower bound heat transfer coefficient to give lower bound values of the rates of excess
enthalpy generation.

It appears to us that Douglas Morrison has failed to understand this point as he continuously
asserts that our demonstrations of excess enthalpy generation are dependent on calibrations and
corrections.

(v) Further with regard to (iii) it appears to us that Douglas Morrison believes that a “null
method” (as used in isothermal calorimeters) is inherently more accurate than say the
isoperibolic calorimetry which we favour. While it is certainly believed that “null” methods in
the Physical Sciences can be made to be more accurate than direct measurements (e.g. when a
voltage difference is detected as in bridge circuits: however, note that even here the advent of
“ramp” methods makes this assumption questionable) this advantage disappears when it is
necessary to transduce the primary signal. In that case the accuracy of all the methods is
determined by the measurement accuracy (here of the temperature) quite irrespective of which
particular technique is used.

In point of fact and with particular reference to the supposed advantages of isothermal versus
isoperibolic calorimetry, we note that in the former the large thermal mass of the calorimeter
appears across the input of the feedback regulator. The broadband noise performance of the
system is therefore poor; attempts to improve the performance by integrating over long times
drive the electronics into 1/f noise and, needless to say, the frequency response of the system is
degraded. (see also (vii) below)

(vi) with regard to implementing measurements with isothermal calorimeters, Douglas
Morrrison recommends the use of internal catalytic recombiners (so that the enthalpy input to the
system is just Ecell.I rather than (Ecell – Ethermoneutral, bath).I as in our “open” calorimeters. We find it interesting that Douglas Morrison will now countenance the introduction of intense local “hot
spots” on the recombiners (what is more in the gas phase!) whereas in the earlier parts of his
critique he objects to the possible creation of microscopic “hot spots” on the electrode surfaces
in contact with the solution.

We consider this criticism from Douglas Morrison to be invalid and inapplicable. In the first
place it is inapplicable because the term Ethermoneutral,bath.I (which we require in our analysis) is
known with high precision (it is determined by the enthalpy of formation of D2O from D2 and
1/2 O2). In the second place it is inapplicable because the term itself is ~ 0.77 Watt whereas we
are measuring a total enthalpy output of ~ 170 Watts in the last stages of the experiment.
(vii) We observe here that if we had followed the advice to use isothermal calorimetry for the
main part of our work, then we would have been unable to take advantage of the “positive
feedback” to drive the system into regions of high excess enthalpy generation (perhaps, stated
more exactly, we would not have found that there is such positive feedback). The fact that there
is such feedback was pointed out by Michael McKubre at the Third Annual Conference of Cold
Fusion and strongly endorsed by one of us (M.F.). As this issue had then been raised in public,
we have felt free to comment on this point in our papers (although we have previously drawn
attention to this fact in private discussions). We note that Douglas Morrison was present at the
Third Annual Conference on Cold Fusion.

(viii) While it is certainly true that the calorimetric methods need to be evolved, we do not
believe that an emphasis on isothermal calorimetry will be useful. For example, we can identify
three major requirements at the present time:

a) the design of calorimeters which allow charging of the electrodes at low thermal inputs and
temperatures below 50 degrees C followed by operation at high thermal outputs and
temperatures above 100 degrees C
b) the design of calorimeters which allow the exploration of Stage 5 of the experiments
c) the design of calorimeters having a wide frequency response in order to explore the transfer
functions of the systems.

We note that c) will in itself lead to calorimeters having an accuracy which could hardly be
rivalled by other methods.

(ix) Douglas Morrison’s critique implies that we have never used calorimetric techniques other
than that described in our recent paper [2]. Needless to say, this assertion is incorrect. It is true,
however, that we have never found a technique which is more satisfactory than the isoperibolic
method which we have described. It is also true that this is the only method which we have found
so far which can be implemented within our resources for the number of experiments which we
consider to be necessary. In our approach we have chosen to achieve accuracy by using
software; others may prefer to use hardware. The question as to which is the wiser choice is
difficult to answer: it is a dilemma which has to be faced frequently in modern experimental
science. We observe also that Douglas Morrison regards complicated instrumentation (three
feedback regulators working in series) as being “simple” whereas he regards data analysis as
being complicated.

Douglas Morrrison also asserts that we have never used more than one thermistor in our
experimentation and he raises this issue in connection with measurements on cells driven to
boiling. Needless to say, this assertion is also incorrect. However, further to this remark is it
necessary for us to point out that one does not need any temperature measurement in order to
determine the rate of boiling of a liquid?

(x) Douglas Morrison evidently has difficulties with our application of non-linear regression
methods to fit the integrals of the differential equations to the experimental data. Indeed he has
such an idee fixe regarding this point that he maintains that we used this method in our recent
paper [2]; we did not do so (see also ‘stage 3 calculations’ above). However, we note that we find
his attitude to the Levenberg-Marquardt algorithm hard to understand. It is one of the most
powerful, easily implemented “canned software” methods for problems of this kind. A classic
text for applications of this algorithm [12] has been praised by most prominent physics journals
and magazines.

(xi) Douglas Morrison’s account contains numerous misleading comments and descriptions. For
example, he refers to our calorimeters as “small transparent test tubes”. It is hard for us to
understand why he chooses to make such misleading statements. In this particular case he could
equally well have said “glass Dewar vessels silvered in their top portion” (which is accurate)
rather than “small transparent test tubes” (which is not). Alternatively, if he did not wish to
provide an accurate description, he could simply have referred readers to Fig 2 of our paper [2].
This type of misrepresentation is a non-trivial matter. We have never used calorimeters made of
test-tubes since we do not believe that such devices can be made to function satisfactorily.

(xii) As a further example of Douglas Morrison’s inaccurate reporting, we quote his last
paragraph in full:

“It is interesting to note that the Fleischmann and Pons paper compares their claimed power
production with that from nuclear reactions in a nuclear reactor and this is in line with their
dramatic claims (9) that “`SIMPLE EXPERIMENT’ RESULTS IN SUSTAINED N-FUSION AT
ROOM TEMPERATURE FOR THE FIRST TIME: breakthrough process has potential to provide
inexhaustible source of energy”.

It may be noted that the present paper does not mention “Cold Fusion” nor indeed consider a possible nuclear source for the excess heat claimed.

Douglas Morrison’s reference (9) reads: “Press release, University of Utah, 23 March 1989.” With regard to this paragraph we note that:

a) our claim that the phenomena cannot be explained by chemical or conventional physical
processes is based on the energy produced in the various stages and not the power output
b) the dramatic claim he refers to was made by the Press Office of the University of Utah and
not by us
c) we did not coin the term “Cold Fusion” and have avoided using this term except in those
instances where we refer to other research workers who have described the system in this way.
Indeed, if readers refer to our paper presented to the Third International Conference on Cold
Fusion [13] (which contains further information about some of the experiments described in [2]),
they will find that we have not used the term there. Indeed, we remain as convinced as ever that
the excess energy produced cannot be explained in terms of the conventional reaction paths of
“Hot Fusion”
d) it has been widely stated that the editor of this journal “did not allow us to use the term Cold
Fusion”. This is not true: he did not forbid us from using this term as we never did use it (see
also [13]).

(xiii) in his section “Conclusions”, Douglas Morrison makes the following summary of his
opinion of our paper:

The experiment and some of the calculations have been described as “simple”. This is incorrect
– the process involving chaotic motion, is complex and may appear simple by incorrectly
ignoring important factors. It would have been better to describe the experiments as “poor”
rather than “simple”.

We urge the readers of this journal to consult the original text [2] and to read Douglas
Morrison’s critique [1] in the context of the present reply. They may well then come to the
conclusion that our approach did after all merit the description “simple” but that the epithet
“poor” should be attached to Douglas Morrision’s critique.

Our own conclusions

We welcome the fact that Douglas Morrison has decided to publish his criticisms of our work
in the conventional scientific literature rather than relying on the electronic mail, comments to
the press and popular talks; we urge his many correspondees to follow his example. Following
this traditional pattern of publication will ensure that their comments are properly recorded for
future use and that the rights of scientific referees will not be abrogated. Furthermore, it is our
view that a return to this traditional pattern of communication will in due course eliminate the
illogical and hysterical remarks which have been so evident in the messages on the electronic
bulletins and in the scientific tabloid press. If this proves to be the case, we may yet be able to
return to a reasoned discussion of new research. Indeed, critics may decide that the proper
course of inquiry is to address a personal letter to authors of papers in the first place to seek
clarification of inadequately explained sections of publications.

Apart from the general description of stages 1-5, we find that the comments made by Douglas
Morrison are either irrelevant or inaccurate or both.

General

Subpage of  Calorimetry of the PD-D2O System: from Simplicity via Complications to Simplicity.

The purpose of this subpage is to study the section named below. Comments here should be aimed toward study and learning as to what is in the Original paper. This is not a place to argue “right” and “wrong,” but to seek agreement, where possible, or to delineate unresolved issues. General comments may be made on the Open discussion subpage.

General Features of our Calorimetry

Our approach to the measurement of excess enthalpy generation in Pd and Pd-alloy
cathodes polarised in D2O solutions has been described in detail elsewhere (see especially (1-5); see also (6)). The form of the calorimeter which we currently use is illustrated in Fig 1. The following features are of particular importance:

(i) at low to intermediate temperatures (say 20-50°C) heat transfer from the cell is dominated by
radiation across the vacuum gap of the lower, unsilvered, portion of the Dewar vessel to the
surrounding water bath (at a cell current of 0.5A and atmospheric pressure of 1 bar, the cooling due to evaporation of D2O reaches 10% of that due to radiation at typically 95-98°C for Dewar cells of the design shown in Fig 1).

(ii) the values of the heat transfer coefficients determined in a variety of ways (see below) both with and without the calibrating resistance heater (see Fig 2 for an example of the temperature-time and cell potential-time transients) are close to those given by the product of the Stefan-Boltzmann coefficient and the radiant surface areas of the cells.

(iii) the variations of the heat transfer coefficients with time (due to the progressive fall of the level of the electrolyte) may be neglected at the first level of approximation (heat balances to within 99%) as long as the liquid level remains in the upper, silvered portions of the calorimeters.

(iv) the room temperature is controlled and set equal to that of the water baths which contain
secondary cooling circuits; this allows precise operation of the calorimeters at low to intermediate
temperatures (thermal balances can be made to within 99.9% if this is required).

(v) heat transfer from the cells becomes dominated by evaporation of D2O as the cells are driven to the boiling point.

(vi) the current efficiencies for the electrolysis of D2O (or H2O) are close to 100%.

ABSTRACT


We present here one aspect of our recent research on the calorimetry of the Pd/D2O system
which has been concerned with high rates of specific excess enthalpy generation (> 1 kWcm-3) at
temperatures close to (or at) the boiling point of the electrolyte solution. This has led to a
particularly simple method of deriving the rate of excess enthalpy production based on measuring
the times required to boil the cells to dryness, this process being followed by using time-lapse video recordings.

Our use of this simple method as well as our investigations of the results of other research
groups prompts us to present also other simple methods of data analysis which we have used in the preliminary evaluations of these systems.


Analysis

These analyses are subject to revision. The goal is consensus. Comment on the analysis below.

Abd

The purpose of the paper is laid out here, to present “one aspect” of “recent research,” a “particularly simple method” of measuring excess power (“rate of excess enthalpy production”), measuring the time necessary to boil to dryness. Not stated in the abstract: while methods are proposed to estimate the enthalpy itself, this would be a comparative method, which would then assess how boil-off times differ between platinum or light water controls, and functioning or non-functioning palladium heavy-water experiments.

The paper also covers “other simple methods,” used in “preliminary evaluations.”

While the abstract mentions a high power density figure (> 1 kWcm-3), that claim is not the stated purpose of the paper, which is about methods.

ABSTRACT

We present here one aspect of our recent research on the calorimetry of the Pd/D2O system
which has been concerned with high rates of specific excess enthalpy generation (> 1kWcm-3) at
temperatures close to (or at) the boiling point of the electrolyte solution. This has led to a

Our use of this simple method as well as our investigations of the results of other research

General Features of our Calorimetry

Our approach to the measurement of excess enthalpy generation in Pd and Pd-alloy
cathodes polarised in D2O solutions has been described in detail elsewhere (see especially (1-5); see also (6)). The form of the calorimeter which we currently use is illustrated in Fig 1. The following features are of particular importance:

(i) at low to intermediate temperatures (say 20-50°C) heat transfer from the cell is dominated by
radiation across the vacuum gap of the lower, unsilvered, portion of the Dewar vessel to the
surrounding water bath (at a cell current of 0.5A and atmospheric pressure of 1 bar, the cooling due to evaporation of D2O reaches 10% of that due to radiation at typically 95-98°C for Dewar cells of the design shown in Fig 1).

(ii) the values of the heat transfer coefficients determined in a variety of ways (see below) both with and without the calibrating resistance heater (see Fig 2 for an example of the temperature-time and cell potential-time transients) are close to those given by the product of the Stefan-Boltzmann coefficient and the radiant surface areas of the cells.

(iii) the variations of the heat transfer coefficients with time (due to the progressive fall of the level of the electrolyte) may be neglected at the first level of approximation (heat balances to within 99%) as long as the liquid level remains in the upper, silvered portions of the calorimeters.

(iv) the room temperature is controlled and set equal to that of the water baths which contain
secondary cooling circuits; this allows precise operation of the calorimeters at low to intermediate
temperatures (thermal balances can be made to within 99.9% if this is required).

(v) heat transfer from the cells becomes dominated by evaporation of D2O as the cells are driven to the boiling point.

(vi) the current efficiencies for the electrolysis of D2O (or H2O) are close to 100%.

Modelling of the Calorimeters

The temperature-time variations of the calorimeters have been shown to be determined by the differential equation [1]

In equation [1] the term allows for the change of the water equivalent with time;
the term β was introduced to allow for a more rapid decrease than would be given by electrolysis
alone (exposure of the solid components of the cell contents, D2O vapour carried off in the gas
stream). As expected, the effects of β on Qf and K0R can be neglected if the cells are operated below 60°C. Furthermore, significant changes in the enthalpy contents of the calorimeters are normally only observed following the refilling of the cells with D2O (to make up for losses due to electrolysis and evaporation) so that it is usually sufficient to use the approximation [2]

The term allows for the decrease of the radiant surface area with time but, as we have already noted, this term may be neglected for calorimeters silvered in the top portion
(however, this term is significant for measurements made in unsilvered Dewars (1); see also (7)). Similarly, the effects of conductive heat transfer are small. We have therefore set Φ = 0 and have made a small increase in the radiative heat transfer coefficient k0R to k’R to allow for this
assumption. We have shown (see Appendix 2 of (1)) that this leads to a small underestimate of Qf (t); at the same time the random errors of the estimations are decreased because the number of parameters to be determined is reduced by one.

We have also throughout used the temperature of the water bath as the reference value and
arrive at the simpler equation which we have used extensively in our work:

Methods of Data Evaluation: the Precision and Accuracy of the
Heat Transfer Coefficients

A very useful first guide to the behaviour of the systems can be obtained by deriving a
lower bound of the heat transfer coefficients (designated by (k’R)6 and/or (k’R)11 in our working manuals and reports) which is based on the assumption that there is zero excess enthalpy generation within the calorimeters:

[4]

The reason why (k’R)11 is a lower bound is because the inclusion of any process leading to the generation of heat within the cells (specifically the heat of absorption of D (or H) within the lattice or the generation of excess enthalpy within the electrodes) would increase the derived value of this heat transfer coefficient: (k’R)11 will be equal to the true value of the coefficient only if there is no such source of excess enthalpy in the cells as would be expected to hold, for example, for the polarisation of Pt in D2O solutions, Fig 2. The simplest procedure is to evaluate these coefficients at a set of fixed times following the addition of D2O to make up for losses due to electrolysis and/or evaporation. Convenient positions are just before the times, t1, at which the calibrating heating pulses are applied to the resistive heaters, Fig 3. For the particular experiment illustrated in Fig 2, the mean value of (k’R)11 for 19 such measurements is 0.7280 × 10-9WK-4 with a standard deviation σ(k’R)11 = 0.0013WK-4 or 0.17% of the mean.

5


Figure 3. Schematic diagram of the methodology used for the calculations.

It is evident therefore that even such simple procedures can give precise values of the heat transfer coefficients but, needless to say, it is also necessary to investigate their accuracy. We have always done this at the next level of complication by applying heater pulses lying in the time range t1 < t < t2 and by making a thermal balance just before the termination of this pulse at t = t2. This time is chosen so that

t2 -t1 ≥ 6τ   [5]

where τ is the thermal relaxation time

[6]

The scheme of the calculation is illustrated in Fig 3: we determine the temperatures and cell potentials at t2 as well as the interpolated values (Δθ1, t2) and [Ecell(Δθ1, t2) ] which would apply
at these times in the absence of the heater calibration pulse. We derive the heat transfer coefficient which we have designated as (k’R)2 using
The mean value of (k’R)2 for the set of 19 measurements is 0.7264WK-4 with a standard deviation  σ(k’R)2 = 0.0099WK-4  or 1.4% of the mean.

6

The comparison of the means and standard deviations of (k’R)2 and (k’R)11 leads to several important conclusions:

(i) in the first place, we note that the mean of (k’R)11 is accurate as well as precise for such blank
experiments: the mean of (k’R)11 is within 0.2σ of the independently calibrated mean values of (k’R)2 ; indeed, the mean of (k’R)11 is also within ~ 1σ of the mean of (k’R)2 so that the differences between (k’R)and (k’R)11 are probably not significant.

(ii) as expected, the precision of (k’R)2 is lower than that of (k’R)11. This is due mainly to the fact
that (k’R)2 (and other similar values) are derived by dividing by the differences between two
comparably large quantities (θbath + Δθ2)4 – (θbath + Δθ1), equation (7). The difference (θbath + Δθ)4 – (θbath)4 used in deriving (k’R)11, equation [4], is known at a higher level of precision.

(iii) the lowering of the precision of (k’R)2 as compared to that of (k’R)11 can be avoided by fitting the integrals of equation [1] (for successive cycles following the refilling of the cells) directly to the experimental data (in view of the inhomogeneity and non-linearity of this differential equation, this integration has to be carried out numerically (1) although it is also possible to apply approximate algebraic solutions at high levels of precision (8)). Since the fitting procedures use all the information contained in each single measurement cycle, the precision of the estimates of the heat transfer coefficients, designated as (k’R)5 , can exceed that of the coefficients (k’R)11. We have carried out these fitting procedures by using non-linear regression techniques (1-5) which have the advantage that they give direct estimates of σ(k’R)5 (as well as of the standard deviations of the other parameters to be fitted) for each measurement cycle rather than requiring the use of repeated cycles as in the estimates of σ(k’R)11 or σ(k’R)2. While this is not of particular importance for the estimation of k’R for the cell types illustrated in Fig 1 (since the effects of the irreproducibility of refilling the cells is small in view of the silvering of the upper portions of the Dewars) it is of much greater importance for the measurements carried out with the earlier designs (1) which were not silvered in this part; needless to say, it is important for estimating the variability of Qf for measurements with all cell designs.

Estimates of k’have also been made by applying low pass filtering techniques (such as the Kalman filter (6) and (8)); these methods have some special advantages as compared to the application of non-linear regression analysis and these advantages will be discussed elsewhere.(8) The values of the heat transfer coefficients derived are closely similar to those of (k’R)5.

Low pass filtering and non-linear regression are two of the most detailed (and complicated) methods which we have applied in our investigation. Such methods have the special advantage that they avoid the well-known pitfalls of making point-by-point evaluations based on the direct application of the differential equation modelling the system. These methods can be applied equally to make estimates of the lower bound heat transfer coefficient, (k’R)11. However, in this case the complexity of such calculations is not justified because the precision and accuracy of (k’R)11 evaluated point-by-point is already very high for blank experiments, see (i) and (ii) above. Instead, the objective of our preliminary investigations has been to determine what information can be derived for the Pd – H2O and Pd – D2O systems using (k’R)11 evaluated point-by-point and bearing in mind the precision and accuracy for blank experiments using Pt cathodes. As we seek to illustrate this pattern of investigation, we will not discuss the methods outlined in this subsection (iii) further in this paper.

(iv) we do, however, draw attention once again to the fact that in applying the heat transfer

7

coefficients calibrated with the heater pulse ΔQH(t – t1) – ΔQH(t – t2) we have frequently used the coefficient defined by and determined at t = t2 to make thermal balances at the point just before the application of the
calibrating heater pulse, Fig 3. The differences between the application of (k’R)2 and (k’R)4 are
negligible for blank experiments which has not been understood by some authors e.g.,(9). However, for the Pd – D2O and Pd alloy – D2O systems, the corresponding rate of excess enthalpy generation, (Qf)2, is significantly larger than is (Qf)4 for fully charged electrodes. As we have always chosen to underestimate Qf, we have preferred to use (Qf)4 rather than (Qf)2.

The fact that (Qf)2 > (Qf)4 as well as other features of the experiments, shows that there is an element of “positive feedback” between the increase of temperature and the rate of generation of excess enthalpy. This topic will be discussed elsewhere (8); we note here that the existence of this feedback has been a major factor in the choice of our calorimetric method and especially in the choice of our experimental protocols. As will be shown below, these provide systems which can generate excess enthalpy at rates above 1kWcm-3.

Applications of Measurements of the Lower Bound Heat Transfer Coefficients to the Investigation of the Pd – D2Ο System

In our investigations of the Pd – D2O and Pd alloy – D2O systems we have found that a
great deal of highly diagnostic qualitative and semi-quantitative information can be rapidly obtained by examining the time-dependence of the lower bound heat transfer coefficient, (k’R)11. The qualitative information is especially useful in this regard as it provides the answer to the key question: “is there generation of excess enthalpy within (or at the surface) of Pd cathodes polarised in D2O solutions?”

We examine first of all the time-dependence of (k’R)11 in the initial time region for the
blank experiment of a Pt cathode polarised in D2O solution which has been illustrated by Fig 2. Fig 4 shows that (k’R)11 rapidly approaches the true steady state value 0.728 × 10-9WK-4 which applies to this particular cell. We conclude that there is no source of excess enthalpy for this system and note that this measurement in itself excludes the possibility of significant re-oxidation of D2 at the anode or re-reduction of O2 at the cathode.

Figure 4. Plot of the heat transfer coefficient for the first day of electrolysis of the experiment described in Fig 2.

We examine next the behaviour of a Pd cathode in H2O, Fig 5. The lower bound heat transfer coefficient again approaches the true value 0.747WK-4 for the particular cell used with
increasing time but there is now a marked decrease of (k’R)11 from this value at short times. As we
have noted above, such decreases show the presence of a source of excess enthalpy in the system which evidently decreases in accord with the diffusional relaxation time of Η+ in the Pd cathode: this source can be attributed to the heat of absorption of H+ within the lattice. We also note that the measurement of (k’R)11 in the initial stages is especially sensitive to the presence of such sources of excess enthalpy because (θbath + Δθ)4 – θbath  0 as t → 0, equation [4]. Furthermore, in the absence of any such source of excess enthalpy the terms [Ecell – Ethermoneutral,bath]I and CP,D2O,lM0(dΔθ/dt) will balance. The exclusion of the unknown enthalpy source must therefore give a decrease of (k’R)11 from the true value of the heat transfer coefficient. We see that this decrease is so marked for the Pd – H2O that (k’R)11 is initially negative! The measurements of (k’R)11 are highly sensitive to the exact conditions in the cell in this region of time, so that minor deviations from the true value (as for the Pt – D2O system, Fig 4) are not significant.

We observe also that measurements of (k’R)11 in the initial stages of the experiments provide an immediate answer to the vexed question: “do the electrodes charge with D+ (or H+)?” It is a common experience of research groups working in this field that some samples of Pd do not give cathodes which charge with D+ (or, at least, which do not charge satisfactorily). A library of
plots of (k’R)11 versus time is a useful tool in predicting the outcome of any given experiment!

We examine next the results for one Pd cathode polarised in D2O solution out of a set of four whose behaviour we will discuss further in the next section. Fig 6B gives the overall temperature-time and cell potential-time data for the second electrode of the set. The overall objective of this part of our investigations has been to determine the conditions required to produce high rates of excess enthalpy generation at the boiling point of the D2O solutions. Our protocol for
the experiment is based on the hypothesis that the further addition of D+ to cathodes already highly loaded with deuterium will be endothermic. We therefore charge the electrodes at low to intermediate current densities and at temperatures below 50°C for prolonged periods of time; following this, the current densities are increased and the temperature is allowed to rise. The D+ is then retained in the cathodes and we take advantage of the “positive feedback” between the temperature and the rate of excess enthalpy generation to drive the cells to the boiling point, Fig 6.

The input enthalpies and the excess enthalpy outputs at selected times are indicated on the diagrams. The current in the first cell was 0.500A. The initial current in each of the other 3 cells was 0.200A, which was increased to 0.500A at the beginning of days 3, 6, and 9, respectively.

 

We examine next the behaviour of the lower bound heat transfer coefficient as a function
of time in three regions, Figs 7A-C. For the first day of operation, Fig 7A, (k’R)11 is initially
markedly negative in view of the heat of dissolution of D+ in the lattice. As for the case of dissolution of H+ in Pd, this phenomenon decays with the diffusional relaxation time so that
(k’R)11 increases towards the true value for this cell, 0.892 × 10-9WK-4. However, (k’R)11 never
reaches this final value because a second exothermic process develops namely, the generation of
excess enthalpy in the lattice. In view of this, (k’R)11 again decreases and we observe a maximum:
these maxima may be strongly or weakly developed depending on the experimental conditions such as the diameter of the electrodes, the current density, the true heat transfer coefficients, the level of excess enthalpy generation etc.

We take note of an extremely important observation: although (k’R)11 never reaches the true value of the heat transfer coefficient, the maximum values of this lower bound coefficient are the minimum values of k’R which must be used in evaluating the thermal balances for the cells. This maximum value is quite independent of other methods of calibration and, clearly, the use of

12

this value will show that there is excess enthalpy generation both at short and at long times. These estimates in Qf (which we denote by (Qf)11 are the lower bounds of the excess enthalpy. The conclusion that there is excess enthalpy generation for Pd cathodes polarised in D2O is inescapable and is independent of any method of calibration which may be adopted so as to put the study on a quantitative basis. It is worth noting that a similar observation about the significance of our data was made in the independent review which was presented at the 2nd Annual Conference on Cold Fusion. (6)

We comment next on the results for part of the second day of operation, Fig 7B. In the
region of the first heater calibration pulse (see Fig 6), (k’R)11 has decreased from the value shown
in Fig 7A. This is due to the operation of the term ΔQ which is not taken into account in
calculating (k’R)11, see equation [4]. As we traverse the region of the termination of the pulse ΔQ,
t=t2, (k’R)11 shows the expected increase. Fig 7B also illustrates that the use of the maximum value of (k’R)11, Fig 7A, gives a clear indication of the excess enthalpy term ΔQ, here imposed by the resistive heater. We will comment elsewhere on the time dependencies of (k’R)11 and of Q in the regions close to t = t1 and t = t2. (8)

The last day of operation is characterised by a rapid rise of temperature up to the boiling point of the electrolyte leading to a short period of intense evaporation/boiling Fig 8. The evidence for the time dependence of the cell contents during the last stages of operation is discussed in the next section. Fig 7C shows the values of (k’R)11 calculated using two assumed atmospheric pressures, 0.953 and 0.97 bars. The first value has been chosen to give a smooth evaporation of the cell contents (M0 = 5.0 D2O) i.e., no boiling during the period up to the point when the cell becomes dry, 50,735 s. However, this particular mode of operation would have required the cell to have been half-full at a time 2.3 hrs before dryness. Furthermore, the ambient pressure at that time was 0.966 bars. We believe therefore that such a mode of operation must be excluded. For the second value of the pressure, 0.97 bars, the cell would have become half empty 11 minutes before dryness, as observed from the video recordings (see the next section) and this in turn requires a period of intense boiling during the last 11 minutes. It can be seen that the heat transfer coefficient (k’R)11 decreases gradually for the assumed condition P = 0.953 bars whereas it stays more nearly constant for P = 0.97 up to the time at which the cell is half-full, followed by a very rapid fall to marked negative values. These marked negative values naturally are an expression of the high rates of enthalpy generation required to explain the rapid boiling during the last 11 minutes of operation. The true behaviour must be close to that calculated for this value of the ambient pressure.

14

Figure 8. Expansion of the temperature-time portion of Fig 6B during the final period of rapid boiling and evaporation.

Figs 9A and B give the rates of the specific excess enthalpy generation for the first and last day corresponding to the heat transfer coefficients, Figs 7A and C. On the first day the specific rate due to the heat of dissolution of D+ in the lattice falls rapidly in line with the decreasing rate of diffusion into the lattice coupled with the progressive saturation of the electrode. This is followed by a progressive build up of the long-time rate of excess enthalpy generation. The rates of the specific excess enthalpy generation for the last day of operation are given for the two assumed atmospheric pressures P*=0.953 and 0.97 bars in Fig 9B. These rates are initially insensitive to the choice of the value of P*. However, with increasing time, (Qf) for the first condition increases reaching ~300 watts cm-3 in the final stages. As we have noted above, this particular pattern of operation is not consistent with the ambient atmospheric pressure. The true behaviour must be close to that for P*=0.97 bars for which (Qf) remains relatively constant at ~ 20W cm-3 for the bulk of the experiment followed by a rapid rise to ~ 4kW cm-3 as the cell boils dry.

A Further Simple Method of Investigating the Thermal Balances for the Cells Operating in the Region of the Boiling Point

It will be apparent that for cells operating close to the boiling point, the derived values of
Qf and of (k’R)11 become sensitive to the values of the atmospheric pressure (broadly for θcell >
97.5°C e.g., see Fig 9B.) It is therefore necessary to develop independent means of monitoring the progressive evaporation/boiling of the D2O. The simplest procedure is to make time-lapse video recordings of the operation of the cells which can be synchronised with the temperature-time and cell potential-time data. Figs 6A-D give the records of the operation of four such cells which are illustrated by four stills taken from the video recordings, Fig 10A-D. Of these, Fig 10A illustrates the initial stages of operation as the electrodes are being charged; Fig 10B shows the first cell being driven to boiling, the remaining cells being still at low to intermediate temperatures; Fig 10C shows the last cell being driven to boiling, the first three having boiled dry; finally, 10D shows all cells boiled dry.

As it is possible to repeatedly reverse and run forward the video recordings at any stage of operation, it also becomes possible to make reasonably accurate estimates of the cell contents. We have chosen to time the evaporation/boiling of the last half of the D2O in cells of this type and this allows us to make particularly simple thermal balances for the operation in the region of the
boiling point. The enthalpy input is estimated from the cell potential-time record, the radiative
output is accurately known (temperature measurements become unnecessary!) and the major enthalpy output is due to evaporation of the D2O. We illustrate this with the behaviour of the cell, Fig 6D, Fig 10D.

We note that excess rate of energy production is about four times that of the enthalpy input even for this highly inefficient system; the specific excess rates are broadly speaking in line with those achieved in fast breeder reactors. We also draw attention to some further important features: provided satisfactory electrode materials are used, the reproducibility of the experiments is high; following the boiling to dryness and the open-circuiting of the cells, the cells nevertheless remain at high temperature for prolonged periods of time, Fig 8; furthermore the Kel-F supports of the electrodes at the base of the cells melt so that the local temperature must exceed 300ºC.

We conclude once again with some words of warning. A major cause of the rise in cell voltage is undoubtedly the gas volume between the cathode and anode as the temperature approaches the boiling point (i.e., heavy steam). The further development of this work therefore calls for the use of pressurised systems to reduce this gas volume as well as to further raise the operating temperature. Apart from the intrinsic difficulties of operating such systems it is also not at all clear whether the high levels of enthalpy generation achieved in the cells in Figs 10 are in any sense a limit or whether they would not continue to increase with more prolonged operation. At a specific excess rate of enthalpy production of 2kW cm-3, the electrodes in the cells of Fig 10
are already at the limit at which there would be a switch from nucleate to film boiling if the current flow were interrupted (we have shown in separate experiments that heat transfer rates in the range 1-10kW cm-2 can be achieved provided current flow is maintained i.e., this current flow extends the nucleate boiling regime). The possible consequences of a switch to film boiling are not clear at this stage. We have therefore chosen to work with “open” systems and to allow the cells to boil to dryness before interrupting the current.

Morrison Fleischmann debate

This is a study of the debate between Douglas Morrison and Stanley Pons and Martin Fleischmann. This debate first took place on the internet, but was then published. It was also covered with copies of drafts from both sides, shown on lenr-canr.org.

Phase 1 of the study
Subpages
Participation is strongly invited.
Britz summaries of the papers

Phase 1 of the study

In this phase, the goal is to thoroughly understand, as far as possible, the expression and intentions of the authors. In the first phase, whether an author is “right” or “wrong” is irrelevant, and if something appears incorrect, a default operating assumption is that the expression was defective or incomplete or has not been understood. In later analysis, this restriction may be removed, and possible error considered.

The original paper being critiqued was M. Fleischmann, S. Pons, “Calorimetry of the Pd-D2O system: from simplicity via complications to simplicity,” Physics Letters A, 176 (1993) 118-129. I have a scan of the original published paper (and Steve Krivit hosts a copy), but I have used here use the more-available version, first presented as a conference paper at ICCF-3 in 1992. There is a later version, presented at ICCF-4 in 1993.

Morrison, D. R. O. (1994). “Comments on claims of excess enthalpy by Fleischmann and Pons using simple cells made to boil.” Phys. Lett. A, 185:498–502. I have a scan, but, again, will use the lenr-canr.org copy.

The original authors then replied with Fleischmann, M.; Pons, S. (1994). “Reply to the critique by Morrison entitled ‘Comments on claims of excess enthalpy by FLeischmann and Pons using simple cells made to boil'”. Phys. Lett. A, 187:276–280. Again, I have a scan of the as-published reply, but will use what is included in the lenr-canr.org copy for convenience.

If there are any significant differences in the versions, I assume they will be found and noted. Meanwhile, this is an opportunity to see what critiques were levelled by Morrison in 1994, and how Pons and Flesichmann replied. Many of the same issues continue to be raised.

Review Committee (new members welcome. This is consensus process and, even after the Committee issues reports, additional good-faith review will remain open here, hopefully, or elsewhere.)

Participation

To participate in this study, comment on the Review Committee page, using a real email address (which will remain confidential) and then begin reviewing the Original paper. (The email address will be used in negotiating consensus, later. Participants will be consulted about process.) Again, the goal at his point is to become familiar with the original paper, what is actually in it (and what is not in it).

Comment here constitutes permission for CFC administration to email you directly (your email address remains private information, not used except for administrative purposes.)

Fleischmann papers are famous for being difficult to understand. Having now edited the complete paper, I’m not ready to claim I understand it all, but it is not as difficult as I’d have expected. The math takes becoming familiar with the symbols, but it is not particularly complex.

Subpages are being created for each section in the article.

If anyone has difficulty understanding something, comment on the relevant subpage and we can look at it. Specify the page number. (I have placed page anchors as well as section anchors in the Original, and equation and figure anchors as well, so you can link directly. There are surely errors in this editing, so corrections are highly welcome.)

Take notes, and you may share them as a comment on that subpage. Please keep a focus in each comment, if possible, on a single section in the paper. I may then reorganize these in subpages that study each section. Comments on the paper itself, at this point, are not for debate or argument, but only for seeking understanding.

(If a subpage has not yet been created for a section, show the subsection title in questions or comment, and these will be moved to the relevant subpage. At this point, please do not “debate.” The goal is understanding, and understanding arises from the comprehension of multiple points of view.)

Overall comment on this process is appropriate on this page.

As Phase 1 completes on the Original, we will move to the Morrison critique, and then, in turn, to the Pons and Fleischmann reply, again with the goal being understanding of the positions and ideas expressed.

In Phase 2 we will begin to evaluate all this, to see if we can find consensus on significance, for example.

Response to comments on my cold fusion status report.

— Morrison comment in 2000 on another Morrison paper, status of cold fusion, correcting errors and replying. This contains many historical references. Much discussion ensued. Morrison appears to be convinced that excess heat measurements are all error, from unexpected recombination, and he also clearly considers failure to find neutrons to be negative against fusion, i.e., he is assuming that if there is fusion, it is standard d-d fusion (which few are claiming any more, and which was effectively ruled out by Fleischmann from the beginning — far too few neutrons, and the neutron report they made was error. Basically, no neutrons is a characteristic of FP cold fusion. This was long after Miles and after Miles was recognized by Huizenga as such a remarkable finding. The discussion shows the general toxicity and hostility. (Not so Morrison himself, who is polite.)

You asked where is the “Overwhelming evidence” against cold fusion? For 
this see the paper “Review of Cold Fusion” which I presented at the ICCF-3 
conference in Nagoya – strangely enough it seems not to have been published 
in the proceedings despite being an invited paper – will send a copy if   
desired.

“Strangely enough,” indeed.

The 2000 paper is on New Energy Times. 

Krivit has collected many issues of the Morrison newsletters on cold fusion.

This is a Morrison review of the Nagoya conference (ICCF-3). Back to sci.physics.fusion:

Fleischmann’s original response to Morrison’s lies

— Post in 2000 by Jed Rothwell and discussion.

Morrison’s Comments Criticized

— Post by Swartz in 1993 (cosigned by Mallove) with Fleischmann reply to Morrison’s critique. Attacks the intentions of Morrison, but this was the original posting of the Fleischmann reply.

I am sure there is more there of interest. We can see how toxic, largely ad-hominem, polarized debate led to little useful conclusions, merely the hardened positions that continue to be expressed.

Hagelstein on the inclusion of skeptics at ICCF 10.

9. Absence of skeptics

Researchers in cold fusion have not had very good luck interacting with skeptics over the years. This has been true of the ICCF conference series. Douglas Morrison attended many of the ICCF conferences before he passed away. While he did provide some input as a skeptic, many found his questions and comments to be uninteresting (the answers usually had been discussed previously, or else concerned points that seemed more political than scientific). It is not clear how many in the field saw the reviews of the conferences that he distributed widely. For example, at ICCF3 the SRI team discussed observations of excess heat from electrochemical cells in a flow calorimeter, where the associated experimental errors were quite small and well-studied. The results were very impressive, and answered basic questions about the magnitude of the effect, signal to noise, dynamics, reproducibility, and dependence on loading and current density. Morrison’s discussion in his review left out nearly all technical details of the presentation, but did broadcast his nearly universal view that the results were not convincing. What the physics community learned of research in the cold fusion field in general came through Morrison’s filter.

Skeptics have often said that negative papers are not allowed at the conference. At ICCF10, some effort was made to encourage skeptics to attend. Gene Mallove posted more than 100 conference posters around MIT several months prior to the conference (some of which remain posted two years later), in the hope that people from MIT would come to the conference and see what was happening. No MIT students or faculty attended, outside of those presenting at the conference. The cold fusion demonstrations presented at MIT were likewise ignored by the MIT community.

To encourage skeptics to attend, invitations were issued to Robert Park, Peter Zimmermann, Frank Close, Steve Koonin, John Holzrichter, and others. All declined, or else did not respond. In the case of Peter Zimmermann, financial issues initially prevented his acceptance, following which full support (travel, lodging, and registration) was offered. Unfortunately his schedule then did not permit his participation. Henceforth, let it be known that it was the policy at ICCF10 to actively encourage the participation of skeptics, and that many such skeptics chose not to participate.

My analysis: the damage had been done. The efforts to include skeptics were too little, too late. The comment that Hagelstein makes about Morrison’s participation is diagnostic: instead of harnessing Morrison’s critique, it is essentially dismissed. Whatever issues Morrison kept bringing up, ordinary skeptics would have the same issues. Peter’s comment is “in-universe,” not seeing the overall context. Skeptics with strongly-developed rejection views would, in general, not consider attending the conference a worthwhile investment of time. That could be remedied, easily. My super-sekrit plan: if conditions are ripe, to invite Gary Taubes to ICCF-21. Shhh! Don’t tell anyone!

(The time is not quite yet ripe, but might be before ICCF-21.)

Short of that, how about an ICCF panel to address skeptical issues and to suggest possible experimental testing of anything not already adequately tested? (And who decides what is adequate? Skeptics, of course! Who else? And for this we need some skeptics! This kind of process takes facilitation, it doesn’t happen by itself, when polarization has set in.)

(This is not a suggestion that experimentalists must anticipate or address every possible criticism. When they can do so, it’s valuable, and the scientific method suggests seeking to prove one’s own conclusions wrong, but that is about interpretation, and  science is also exploration, and in exploration, one reports what one sees and does not necessarily nail down every possible detail.)

Cold fusion: Manual for the Compleat Idiot

There is a decent video by Jed Rothwell

Unfortunately it repeats some common tropes that can make an approach to understanding cold fusion more difficult (as they did from the beginning). Rather than take this apart, what would be a better introduction? I’m using a recent post by Jed Rothwell as a seed that may create one.

On LENR Forum, Jed Rothwell wrote:

So how do we establish that LENR has been replicated? We are surrounded by hyperskeptics, whom I have no real interest in appeasing because their standard, if it were applied to any other branch of science, would send us back to some kind of stone age.

I recommend you ignore the hyperskeptics. I engage with them here only to keep in practices, as an exercise in rhetorical target practice.

Great excuse! Someone is wrong on the internet! There goes countless hours. This is useful if one actually hones literary and rhetorical skills, but, too often, there is no genuine feedback, no objective standard or measure of success. What, indeed, is success? What I’ve gained from the engagement is familiarity with the issues. It enables me to speak cogently, off-the-cuff. We’ll see how effective that is!

We are not, however, “surrounded by hyperskeptics.” Where does Kev live that he thinks this way? Planet Rossi? If someone new is not skeptical about cold fusion, they don’t understand the problem.

I recommend you concentrate instead on trying to persuade open minded people who are sincerely interested in the subject. There are apparently a large number of such people. Although the numbers seem to be dropping off. See:

lenr-canr.org statistics

I’ve been writing for years about this. A goal of “persuading” people can be disempowering. How about “inspiring” them? Short of that, “informing” them. Of what? Our opinions? Continue reading “Cold fusion: Manual for the Compleat Idiot”
