Report: 'Stable Excess Heat', '100 Per Cent Reproducible' in LENR Experiment at Tohoku University, Japan

Thanks to reader Bob (not Greenyer) for a comment today which cites a new report by Kenji Kaneko, Nikkei BP Clean Tech Institute, translated from the orginal Japanese by Jed Rothwell and posted on the LENR-CANR website here: It reports on work taking place at the Condensed Matter Nuclear Science (CMNS) Department at Tohoku University, Japan where researchers are reporting successful production of excess heat in experiments that are apparently still ongoing.

Here’s an excerpt from the article:

Clean Planet has invested in joint research with Dr. Mizuno’s company Hydrogen Engineering Application and Development Company (Sapporo). Research professor of Tohoku University Iwamura and his colleagues’ first efforts were to reproduce the experiment devised by Dr. Mizuno, and they have made steady progress in observing “excess heat.”

The technique works like this. There are two wire-like palladium electrodes arranged in a cylindrical chamber, with the periphery surrounded by a nickel mesh. [5] High voltage is applied to the electrodes, causing glow discharge. After this treatment the electrodes are heated (baked) at 100 ~ 200°C. As a result, the surface of the palladium wire is covered with a film made up of a
structure of nanoscale palladium and nickel particles.

After processing in this way to activate the palladium surface, the chamber is evacuated, while being heating up to several hundred degrees with a resistance heater. Deuterium gas is then introduced at high pressure (300 ~ 170 Pa), enough to sufficiently ensure contact between the palladium and deuterium. Then, “excess heat” exceeding the heat from the resistance heater input power is observed. When researchers introduce deuterium gas in the same apparatus under the same conditions but without doing the activation treatment first, excess heat is not observed. The excess heat causes a temperature difference ranging from about 70 ~ 100°C.

Iwamura describes the project with enthusiasm. “The experimental project has only been underway for about a year, but it is going better than we expected and we already have stable excess heat. We are applying the knowledge accumulated in our research at Mitsubishi Heavy Industries, demonstrating that highly reproducible element conversion techniques can also be applied to heat generation.”

I hadn’t seen this report until today, but it does sound like the establishment of the CMNS at Tohaku is bearing fruit with some demonstrable method to produce excess heat which the authors say is “100% reproducible.” I imagine this work will be of interest to all followers of LENR, and especially to replicators.

    Because there have been too many false news and disapointments

    Sent a link to Science Daily blog.

  • Bob Matulis

    I like the fact that they have an easily testable variable. That is, running the experiment with and without deuterium. If the experiment can be run multiple times changing that one variable and consistently a higher temperature is found with the deuterium that is scientifically significant. The comparative temperature in this case is what matters rather than having to prove COP etc.

    • Josh G

      Deuterium is not the variable. Treating the palladium is the key change.

      • Bob Matulis

        Thanks for the clarification. I misread the report above.

      • Warthog

        Correct, but this approach also apparently allows Ed Storms “nuclear active environment” to be generated with 100% reliability. Which, in turn, will allow it to be studied directly, and probably optimized a great deal.

        • Josh G

          Yes, it’s revolutionary. Though reportedly the SPAWAR co-deposition approach is/was also 100% reproducible.

          • Warthog

            Yes (though some have claimed otherwise on the 100%). But the co-dep approach is still electrochemical, and thus limited in maximum temperature without huge engineering problems from pressure.

            And at risk of adding an element of non-science….as I read about the experimental setup, it just “feels right”.

  • Gerard McEk

    I believe this is great! The details are presented in the ICCF20 I hope, that’s next week. I look forward for it.

  • pg

    Anyone knows about the COP?

    • bachcole

      Yeah, that is sort of the most important thing. Without a COP > 1.00 it is useless that it is 100% reliable.

      • Frank Acland

        By definition excess heat means COP greater than 1, but in this case we don’t know the energy in/out yet.

      • Warthog

        Not correct. If ANY device can demonstrably cause fusion reactions at “…a few hundred degrees…” with 100% experimental repeat-ability it is extraordinarily important no matter what the COP. COP then becomes simply a matter of engineering. But the article does indicate over-unity performance.

        • TVulgaris

          The COP pretty much HAS to be >1, otherwise the heat can’t be construed as “excess”, the rest, as you point out, is engineering for performance. What is ringing very loud klaxons for me is this is the same “technique” (read, device and regimen) they have achieve full control now for elemental transmutation.

          • Warthog

            “Then, “excess heat” exceeding the heat from the resistance heater input power is observed.”

            Above is the direct statement from the translated article…heat output is greater than applied heater input power. However, if one can produce nuclear fusion at “a few hundred degrees” it is just as much a violation of known physics at a COP of say 0.9 as at a COP of 9..

          • georgehants

            Good news, but if this report does not contain all of the information necessary for MFMP or anybody skilled in the art to replicate openly their claimed effect, then it is just another claim such as Rossi’s etc.
            The first people to publish an open, repeatable method to produce an over unity Cold Fusion are the ones who will claim all the glory etc.
            Bob from MFMP below reports that they may be in position to give such a demonstration and report shortly.
            Best wishes to everybody involved in Cold Fusion, but only an open, freely reproducible, claim will take the prize.

          • Sandy

            James A. Patterson patented a cold fusion device that included small plastic beads coated with layers of nickel and palladium and nickel. So I am not surprised that the successful experiment conducted at Tohoku University involved palladium wire “activated” with “nickel particles”.

  • Ophelia Rump

    They are waiting for permission from MIT.

  • Ophelia Rump

    That is a game changer, now if only the game would change.

    • Bob Greenyer

      If criminal politicians and bankers start getting put behind bars – I think we have a good chance of changing things.


      We just do it in spite of those that would suppress it.

      • Thomas Kaminski

        Since it was first baked in a vacuum, I guess 300 Pa would be a big pressure change over ambient…..

  • Warthog

    NO experiment is ever “replicated at will”, that isn’t true even of mass-produced and sold items. ALL technology/experiments will sometimes fail. LENR “has” been replicated years ago by any honest rules of science. Any one saying that is not the case is simply lying, or quoting someone who is lying.

  • R101

    then we would be driving CF powered flying cars by now!

    Fixed that for you Bob 🙂

  • bachcole

    I am feeling very positive about this, and I expect great things in the future. However, if I understand the report properly, they are comparing ingredient A with ingredient B and saying that that means “excess heat”. I would feel much more certain if they divided the output by the input and called that “excess heat”. I understand that measuring output can be a bi1ch.

  • Josh G

    Good points!

  • Barbierir

    I see on pacermonitor that IH counterclaims have been updated, maybe they found Bass?

  • Bob Greenyer

    No – this is an older Mizuno replication.

    We will announce how we are planning to replicate this family (Canon / Clean Planet / Dielectric Barrier Discharge DBD – German Patent) in the coming week.

  • Private Citizen

    Read the link and saw no info on ash analysis.

    Curious, to announce “excess heat” 100% reproducible for one year, describe in some detail the technique, but hold back on really key isotopic ash evidence.

    Looking forward to seeing hard data.

    • bachcole

      And also the COP.

    • Warthog

      Some sort of multi-body phenomenon pretty much “has” to be what is happening. And it has to involve not only allowing the prospective fusing nuclei to “get together”, but also dissipating the mass-energy loss/conversion in a way that does not involve emission of high-energy gammas or neutrons for the vast majority of the energy liberated.

      (and please pardon the run-on sentence above!).

  • Bob Greenyer

    The balls could be H2 D2 exchange – it is not that.

    No – this is MUCH more convincing and visual – and convincing to the people that need to be convinced like physicists before this field will really hit main stream.

  • Bob Greenyer

    Fantastic – keep going! I like the handle by the way – very Cockcroft and Walton.

  • bachcole

    Just for fun, folks, keep in mind that the pronunciation that you probably derive from the spelling of any foreign language, especially one that is very “far” from English, is NOT the pronunciation that the native speakers are doing conversationally. In fact, it is almost certain that even if a native Japanese non-English speaker were to pronounce ANY Japanese word in your face, you would not be able to understand what he/she just said to you. This includes “Tohoku”, “Yokohama”, etc. etc. etc. Even if you knew what the word was that was coming in a sentence, it is still likely that you wouldn’t be able to know which word it was that you were expecting. In fact, you will have trouble distinguishing between one word and another when you are being spoken to.

    I often watch also while my wife is watching Korean dramas. They give the text in English of what is being said, and often someone’s name is pronounced or some English word is pronounced. But when I compare the text with what I am hearing via the audio, I am completely stumped.

    Here’s the thing. It is us-centric to think that other people say the same sounds that we do, so it is foolish to think that they are going to spell their English version of their words in a way that makes it perfectly clear what their sounds are for their words. The “th” sound; fo-get about it. That is pretty rare in the rest of the world. They don’t have the same consonant sounds. They don’t have the same vowel sounds. It is very nice that Japanese have a consistent spelling in English for their words, but don’t expect that in many other languages. Arabic does not have a consistent spelling in English for their words. As an old dude, I have had to endure numerous spellings of Qaddafi, the former dictator of Libya. Even the name of their Holy Book has gone through at least two English language spelling versions; but I guarantee that their pronunciation has not changed much. This is the case with most non-IndoEuropean languages. In my wife’s native tongue, I see various spellings for the same word.

    So, the bottom line is that when, not if, some of you guys travel to Japan for an LENR conference, it would be a good idea to take an Japanese vocal-to-vocal, vocal-to-text, and text-to-vocal translator app. Both they and you will appreciate it. But don’t expect it will be easy to pronounce their words, no matter how good the app is.

    When I first met my wife, I tried to say their version of “Oh my God”. I had heard it numerous times. I ended up saying their version of “I masturbate.” Do you understand now? (:->)

    • Ged

      A good case in point is the Japanese “r”. Japanese does not actually have the English r or l sounds, and English physically does not have the Japanese “r” sound (it is made with the part of the tongue between the English d and l, which is physically unused in English). It is a unique sound that English speakers often confuse for r or l. It has taken me a lot of work to train the muscles to be able to make the Japanese “r”, and I still can’t enunciate it with full fluidity yet (especially “re”). And if course, this isn’t even considering dialect variations.

      But, it is good to note as a general rule of thumb that native Japanese usually appreciate it when foreigners try to speak in their language, rather than forcing them to use the foreigners’. Doesn’t matter how bad one is at it, most people will be much more amiable and willing to help if you try to talk to them in Japanese first, even if you have to resort to English or apps in the end. It is simply seen as respectful and polite.

    IMO the nickel atoms implanted beneath the palladium surface are the key here. The baking of electrodes has its meaning after ion implantation, as it heals the lattice broken with impacted ions. The palladium provides necessary hydrogen/deuterium oversaturation – but there were always reports that the actual LENR runs at the foreign atoms (Ru, Rh) embedded into the palladium lattice and the actual palladium purity has been fuzzy factor of LENR success often. At any case, the economically viable LENR should be able to run without surplus of palladium. IMO the nature of nickel film isn’t crucial here, otherwise the whatever else substrate could be used.

    Otherwise this study is worth to study in this extent
