Takahashi and New Hydrogen Energy

Today I began and completed a review of Akito Takahashi’s presentation on behalf of a collaboration of groups, using the 55 slides made available. Eventually, I hope to see a full paper, which may resolve some ambiguities. Meanwhile, this work shows substantial promise.

This is the first substantial review of mine coming out of ICCF-21, which, I declared, the first day, would be a breakthrough conference.

I was half-way out-of-it for much of the conference, struggling with some health issues, exacerbated by the altitude. I survived. I’m stronger. Yay!

Comments and corrections are invited on the reviews, or on what will become a series of brief summaries.

The title of the presentation: Research Status of Nano-Metal Hydrogen Energy. There are 17 co-authors, affiliated with four universities (Kyushu, Tohoku, Kobe, and Nagoya), and two organizations (Technova and Nissan Motors). Funding was reportedly $1 million US, for October 2015 to October 2017.

This was a major investigation, finding substantial apparent anomalous heat in many experiments, but this work was, in my estimation, exploratory, not designed for clear confirmation of a “lab rat” protocol, which is needed. They came close, however, and, to accomplish that goal, they need do little more than what they have already done, with tighter focus. I don’t like presenting “best results,” from an extensive experimental series, it can create misleading impressions.

The best results were from experiments at elevated temperatures, which requires heating the reactor, which, with the design they used, requires substantial heating power. That is not actually a power input to the reactor, however, and if they can optimize these experiments, as seems quite possible, they appear to be generating sufficient heat to be able to maintain elevated temperature for a reactor designed to do that. (Basically, insulate the reactor and provide heating and cooling as needed, heating for startup and cooling once the reactor reaches break-even — i.e., generating enough heat to compensate for heat losses). The best result was about 25 watts, and they did not complete what I see as possible optimization.

They used differential scanning calorimetry to identify the performance of sample fuel mixtures. I’d been hoping to see this kind of study for quite some time. This work was the clearest and most interesting of the pages in the presentation; what I hope is that they will do much more of that, with many more samples. Then, I hope that they will identify a lab rat (material and protocol) and follow it identically with many trials (or sometimes with a single variation, but there should be many iterations with a single protocol.

They are looking forward to optimization for commercial usage, which I think is just slightly premature. But they are close, assuming that followup can confirm their findings and demonstrate adequate reliability.

It is not necessary that this work be fully reliable, as long as results become statistically predictable, as shown by actual variation in results with careful control of conditions.

Much of the presentation was devoted to Takahashi’s TSC theory, which is interesting in itself, but distracting, in my opinion, from what was most important about this report. The experimental work is consistent with Takahashi theory, but does not require it, and the work was not designed to deeply vet TSC predictions.

Time was wasted in letting us know that if cold fusion can be made practical, it will have a huge impact on society. As if we need to hear that for the n thousandth time. I’ve said that if I see another Rankin diagram, I’d get sick. Well, I didn’t, but be warned. I think there are two of them.

Nevertheless, this is better hot-hydrogen LENR work than I’ve seen anywhere before. I’m hoping they have helium results (I think they might,) which could validate the excess heat measures for deuterium devices.

I’m recommending against trying to scale up to higher power until reliability is nailed.

Update, July 1, 2018

There was reference to my Takahashi review on LENR Forum, placed there by Alain Coetmeur, which is appreciated. He misspelled my name. Ah, well!

Some comments from there:

Alan Smith wrote:

Abd wrote to Akito Takahashi elsewhere.

“I am especially encouraged by the appearance of a systematic approach, and want to encourage that.”

A presumptuous comment for for somebody who is not an experimenter to make to a distinguished scientist running a major project don’t you think? I think saying ‘the appearance’ really nails it. He could do so much better.

That comment was on a private mailing list, and Smith violated confidentiality by publishing it. However, no harm done — other than by his showing no respect for list rules.

I’ll point out that I was apparently banned on LENR Forum, in early December, 2016, by Alan Smith. The occasion was shown by my last post. For cause explained there, and pending resolution of the problem (massive and arbitrary deletions of posts — by Alan Smith — without notice or opportunity for recovery of content), I declared a boycott. I was immediately perma-banned, without notice to me or the readership.

There was also an attempt to reject all “referrals” to LENR Forum from this blog, which was easily defeated and was then abandoned. But it showed that the problem on LF was deeper than Alan Smith, since that took server access. Alan Coetmeur (an administrator there) expressed helplessness, which probably implicated the owner, and this may have all been wrapped in support for Andrea Rossi.

Be that as it may, I have excellent long-term communication with Dr. Takahashi. I was surprised to see, recently, that he credited me in a 2013 paper for “critical comments,” mistakenly as “Dr. Lomax”, which is a fairly common error (I notified him I have no degree at all, much less a PhD.) In that comment quoted by Smith, “appearance” was used to mean “an act of becoming visible or noticeable; an arrival,” not as Smith interpreted it. Honi soit qui mal y pense.

I did, in the review, criticize aspects of the report, but that’s my role in the community, one that I was encouraged to assume, not by myself alone, but by major researchers who realize that the field needs vigorous internal criticism and who have specifically and generously supported me to that end.

Shane D. wrote:

Abd does not have much good to say about the report, or the presentation delivery.

For those new to the discussion, this report…the result of a collaboration between Japanese universities, and business, has been discussed here under various threads since it went public. Here is a good summation: January 2018 Nikkei article about cold fusion

Overall, my fuller reaction was expressed here, on this blog post. I see that the format (blog post here, detailed review as the page linked from LF) made that less visible, so I’ll fix that. The Nikkei article is interesting, and for those interested in Wikipedia process, that would be Reliable Source for Wikipedia. Not that it matters much!

Update July 3, 2018

I did complain to a moderator of that private list, and Alan edited his comment, removing the quotation. However, what he replaced it with is worse.

I really like Akito. Wonderful man. And a great shame Abd treats his work with such disdain.

I have long promoted the work of Akito Takahashi, probably the strongest theoretician working on the physics of LENR. His experimental work has been of high importance, going back decades. It is precisely because of his position in the field that I was careful to critique his report. The overall evaluation was quite positive, so Smith’s comment is highly misleading.

Not that I’m surprised to see this from him. Smith has his own agenda, and has been a disaster as a LENR Forum moderator. While he may have stopped the arbitrary deletions, he still, obviously, edits posts without showing any notice.

This was my full comment on that private list (I can certainly quote myself!)

Thanks, Dr. Takahashi. Your report to ICCF-21 was of high interest, I have reviewed it here:


I am especially encouraged by the appearance of a systematic approach, and want to encourage that.

When the full report appears, I hope to write a summary to help promote awareness of this work.

I would be honored by any corrections or comments.

Disdain? Is Smith daft?

Overall reaction to this presentation is in a blog post. This review goes over each slide with comments, and may seem overly critical. However, from the post:

. . . this is better hot-hydrogen LENR work than I’ve seen anywhere before.

6Kobe University

Two MHE facilities at Kobe University and Tohoku University and a DSC (differential
scanning calorimetry) apparatus at Kyushu University have been used for excess-heat
generation tests with various multi-metal nano-composite samples under H(or D)-gas
charging. Members from 6 participating institutions have joined in planned 16 times
test experiments in two years (2016-2017). We have accumulated data for heat generation
and related physical quantities at room-temperature and elevated- temperature conditions,
in collaboration. Cross-checking-style data analyses were made in each party and
compared results for consistency. Used nano-metal composite samples were PS(Pd-SiO2)
-type ones and CNS(Cu-Ni-SiO2)-type ones, fabricated by wet-methods, as well as PNZ
(Pd-Ni-Zr)-type ones and CNZ(Cu-Ni-Zr)-type ones, fabricated by melt-spinning and
oxidation method. Observed heat data for room temperature were of chemical level.

Results for elevated-temperature condition: Significant level excess-heat evolution data
were obtained for PNZ-type, CNZ-type CNS-type samples at 200-400℃ of RC (reaction
chamber) temperature, while no excess heat power data were obtained for single nanometal
samples as PS-type and NZ-type. By using binary-nano-metal/ceramics-supported
samples as melt-span PNZ-type and CNZ-type and wet-fabricated CNS-type, we
observed excess heat data of maximum 26,000MJ per mol-H(D)-transferred or 85 MJ
per mol-D of total absorption in sample, which cleared much over the aimed target value
of 2MJ per mol-H(D) required by NEDO. Excess heat generation with various Pd/Ni
ratio PNZ-type samples has been also confirmed by DSC (differential scanning
calorimetry) experiments, at Kyushu University, using very small 0.04-0.1g samples at
200 to 500℃ condition to find optimum conditions for Pd/Ni ratio and temperature. We
also observed that the excess power generation was sustainable with power level of 10-
24 W for more than one month period, using PNZ6 (Pd1Ni10/ZrO2) sample of 120g at
around 300℃. Detail of DSC results will be reported separately. Summary results of
material analyses by XRD, TEM, STEM/EDS, ERDA, etc. are to be reported elsewhere.

This is a summary of Takahashi TSC theory. Takahashi found that the rate of 3D fusion in experiments where PdD was bombarded by energetic deuterons was enhanced 10^26, as I recall, over naive plasma expectation. This led him to investigate multibody fusion. 4D, to someone accustomed to thinking of plasma fusion, may seem ridiculously unlikely; however, this is actually only two deuterium molecules. We may image two deuterium molecules approaching each other in a plasma and coming to rest at the symmetric position as they are slowed by repulsion of the electron clouds. However, this cannot result in fusion in free space, because the forces would dissociate the molecules, they would slice each other in two. However, in confinement, where the dissociating force may be balanced by surrounding electron density, it may be possible. Notable features: the Condensate that Takahashi predicts includes the electrons. Fusion then occurs by tunneling to 100% within about a femtosecond; Takahashi uses Quantum Field Theory to predict the behavior. To my knowledge, it is standard QFT, but I have never seen a detailed review by someone with adequate knowledge of the relevant physics. Notice that Takahashi does not detail how the TSC arises. We don’t know enough about the energy distribution of deuterium in PdD to do the math. Because the TSC and resulting 8Be are so transient, verifying this theory could be difficult.

Takahashi posits a halo state resulting from this fusion that allows the 8Be nucleus, with a normal half-life of around a femtosecond, to survive long enough to radiate most of the energy as a Burst of Low-Energy Photons (BOLEP), and suggests a residual energy per resulting helium nucleus of 40 – 50 KeV, which is above the Hagelstein limit, but close enough that some possibility remains. (This energy left is the mass difference of the ground state for 8Be over two 4He nuclei.)

Notice that Takahashi does not specify the nature of the confining trap that allows the TSC to arise. From experimental results, particularly where helium is found, the reaction takes place on the surface, not in the bulk, so the trap must only be found on (or very near) the surface. Unless a clear connection is shown, this theory is dicta, not really related to the meat of the presentation, experimental results.

  • Page 5: Comparison of Energy-Density for Various Sources.  We don’t need this fluff. (The energy density, if “cold fusion” is as we have found, is actually much higher, because it is a surface reaction, but density is figured for the bulk. Bulk of what? Not shown. Some LENR papers present a Rankin diagram, which is basically the same. It’s preaching to the choir; it was established long ago and is not actually controversial: if “cold fusion” is real, it could have major implications, providing practical applications can be developed, which remains unclear. What interests us (i.e., the vast majority of those at an ICCF conference) is two-fold: experimental results, rather than complex interpretations, and progress toward control and reliability.
  • Page 6: Comparison of Various Energy Resources. Please, folks, don’t afflict this on us in what is, on the face, an experimental report. What is given in this chart is to some extent obvious, to some extent speculative. We do not know the economics of practical cold fusion, because it doesn’t exist yet. When we present it, and if this is seen by a skeptic, it confirms the view that we are blinded by dreams. We aren’t. There is real science in LENR, but the more speculation we present, the more resistance we create. Facts, please!!!
  • Page 7. Applications to Society. More speculative fluff. Where’s the beef? (I don’t recall if I was present for this talk. There was at least one where I found myself in an intense struggle to stay awake, which was not helped by the habit of some speakers to speak in a monotone, with no visual or auditory cues as to what is important, and, as untrained speakers (most in the Conference, actually), no understanding of how to engage and inspire an audience. Public speaking is not part of the training of scientists, in general. Some are good at it and become famous. . . . ) (I do have a suggested solution, but will present it elsewhere.)
  • Page 8. Required Conditions to Application: COP, E-density, System-cost. More of the same. Remarkable, though: The minimum power level for a practical application shown is 1 KW. The reported present level is 5 to 20 W. Scientifically, that’s a high level, of high interest, and we are all eager to hear what they have done and found. However, practically, this is far, far from the goal. Note that low power, if reliable, can be increased simply by scaling up (either making larger reactors or making many of them; then cost may become an issue. This is all way premature, still.) By this time, if I was still in the room, I’m about to leave, afraid that I’ll actually fall asleep and start snoring. That’s a bit more frank and honest with our Japanese guest than I’d want to be. (And remember, my sense is that Takahashi theory is the strongest in the field, even if quite incomplete. Storms has the context end more or less nailed, but is weak on theory of mechanism. Hagelstein is working on many details, various trees of possible relevance, but still no forest.)

These were difficult to decode. Some tests were actually two tests, one at RT (Room Temperature) and another at ET (Elevated Temperature). Other than the DSC test, the samples tested were all different in some way, or were they?

“20% difference between the integrated values evaluated from TC2 and those
from RTDav : due to inhomogeneity of the 124.2-g sample distributed in the
ZrO2 [filler].” How do we know that? What calibrations were done? Is this test 14 from Page 17? If so, the more optimistic result was included in the table summary. The behavior is unclear.

Page 19. Using Same Samples divided(CNZ5=Cu1Ni7/ZrO2)100g, parallel tests. This would be test 4 (Kobe, CNZ5), test 6 (Tohoku, CNZ5s)

The labs are not presenting data in the same format. It is unclear what is common and what might be different. The behaviors are not the same, regardless, which is suspicious if the samples are the same and they are treated the same. The difference, then, could be in the calorimetry or other aspects of the protocol not controlled well. The input power is not given in the Kobe plot. (This is the power used to maintain elevated temperature). It is in the Tohoku plot, it is 80 W, initially, then is increased to 134 W.

“2~8W of AHE lasted for a week at Elevated Temp. (H-gas)” is technically sort-of correct for the Kobe test (i.e., between 2 and 8 watts of AHP (this is power, not energy)  started out at 8 W average and declined steadily until it reached 2 W after 3.5 days. Then it held at roughly this level for three days, then there is an unexplained additional brief period at about 4 W. The Tohoku test showed higher power, but quite erratically. After almost rising to 5 W, for almost a day, it collapsed to zero, then rose to 2 W. Then, if this is plotted correctly, the input power was increased to raise the temperature. (for an environmental temperature, which  this was intended to be, the maintenance power is actually irrelevant, it should be thermostatically controlled — and recorded, of course. Significant XP would cause a reduction in maintenance power, as a check. But if they used constant maintenance power, then we would want to know the environment temperature, which should rise with XP. But only a little in this experiment, XP being roughly 2% of heating power. At about 240 hours, the XP jumped to about 3.5 W. I have little confidence in the reliability of this data, without knowing much more than is presented.

Page 20. 14-th Coll. Test(PNZ6): Largest AHE Data 

“Wex: 20W to 10W level excess-power lasted for a month.” This is puffery, cherry-picking data from a large set to create an impressive result. Yes, we would want to know the extremes, but both extremes, and we would even more want to know what is reliable and reproducible. This work is still “exploratory,” it is not designed, so far, to develop reliability and confidence data. The results so far are erratic, indicating poor control. Instead of using one material — it would not need to be the “best” — they have run a modest number of tests with different materials. Because of unclear nomenclature, it’s hard to say how many were different. One test is singled out as being the same material in two batches. I’d be far more interested in the same material in sixteen batches, all with an effort that they be thoroughly mixed, as uniform as possible, before dividing them. Then I’d want to see the exact same protocol run, as far as possible, in the sixteen experiments. Perhaps the only difference would be the exact calorimetric setup, and I’d want to see dummy runs in both setups with “fuel” not expected to be nuclear-active.

One of the major requirements for calorimetric work, too often neglected, is to understand the behavior of the calorimeter thoroughly, across the full range of experimental conditions. This is plodding work, boring. But necessary.

We learn fastest when we are wrong. They have a decent number of samples at low ratio, with the heat increasing with the Ni, but then only one data point above the ratio of 7. That region is of maximum interest if we want to maximize heat. One point can be off for many reasons, and, besides, where is the actual maximum? As well, the data for 7 could be the bad point. It actually looks like the outlier. Correlation! Don’t leave home without it. Gather lots of data with exact replication or a single variable . Science! Later, on P. 44, Takahashi provides a possible explanation for an optimal value somewhere around 1:7., but the existence of an “explanation” does not prove the matter.

This contradicts the idea that the optimal Pd/Ni ratio is 1:7, pointing to a possible flyer in the DSC data at Pd/Ni 1:7, which was used for many experiments. It is possible from the DSC data, then, that 100% Ni would have even higher power results (or 80 or 90%). Except for that single data point, power was increasing with Ni ratio, consistently and clearly. (I’d want to see a lot more data points, but that’s what appears from what was done.) This result (largest) was consistent between #1 and #2. I’m assuming that (“#”) means two identical subsamples.

    Control / Find factors, theory / Speculation by experiments, construct theory
    Lower cost / Low cost nanocomposites / Optimum binary, lower cost fabrication

I disagree that those are the next phase. The first phase would ideally identify and confirm a reasonably optimal experiment. That is not actually complete, so completing it would be the next phase. This completion would use DSC to more clearly and precisely identify an optimal mixture (with many trials). A single analytical protocol would be chosen and many experiments run with that single mixture and protocol. Combining this with exploration, in attempt to “improve,” except in a very limited and disciplined way, will increase confusion. The results reported already show very substantial promise. 10-25 watts, if that can be shown to be reasonably reliable and predictable, is quite enough. Higher power at this point could make the work much more complex, so keep it simple.

Higher power then, could be easy, by scaling up, and then, as well, increasing COP could be easy by insulating the reactor to reduce heat loss rate. With sufficient scale and insulation, the reaction should be able to become self-sustaining, i.e., maintaining the necessary elevated environmental temperature with its own power.

Theory of mechanism is almost completely irrelevant at this point. Once there is an identified lab rat, then there is a test bed for attempting to verify — or rule out — theories. Without that lab rat, it could take centuries. At this point, as well, low cost (i.e., cost of materials and processing) is not of high significance. It is far more important at this time to create and measure reliability. Once there is a reliable experiment, as shown by exact and single-variable replications, then there is a standard to apply in comparing variables and exploring variations, and cost trade-0ffs can be made. But with no reliable reactor, improving cost is meaningless.

This work was almost there, could have been there, if planned to complete and validate a lab rat. DSC, done just a little more thoroughly, could have strongly verified an optimal material. It is a mystery to me why the researchers settled on Pd/Ni of 7. (I’m not saying that’s wrong, but it was not adequately verified, as far as what is reported in the presentation.

Within a design that was still exploratory, it makes sense, but moving from exploration to confirmation and measuring reliability is a step that should not be skipped, or the probability is high that millions of dollars in funding could be wasted, or at least not optimally used. One step at a time wins, in the long run.
