No Input LENR? — Deuo Dynamics Paper

Thanks to those yesterday who brought attention to a paper posted on Cold Fusion Now written by Fabrice David and John Giles of the British company Deuo Dynamics which describes an experiment in which voltage is produced in diodes containing deuterium charged palladium in contact with a semiconductor.

Here’s the abstract from the article:

Conventionally, the cold fusion reaction produces heat. The authors have sought a different approach, wherein the device has no input energy, relying on the energy produced by cold fusion in the device. The device consists of diodes fabricated as powder, with a large surface junction made up of a semiconductor in contact with palladium charged with deuterium.

The apparent fusion reactions take place in the junction between the semiconductor and the Palladium powder, which produces an excitation which is transmitted to the electrons. This excitation increases their energy and allows them to cross the bandgap of the semiconductor and pass into the conduction band, as in a photovoltaic cell. This energy very quickly appears as a spontaneous potential difference which can reach over 0.5 volt per junction.

The potential drop concentrates on the junction region, and at a nano scale the electric field reaches considerable values, higher than the megavolt per meter, which constrains the deuterium nuclei and increases the probability of deuterium fusion.

With no energy input, the authors report that when they introduced deuterium into the device (after first trying to exclude environmental noise by successively charging it with argon and hydrogen) the voltage in the cell ‘quickly rises from zero to 0.5V.” They say that after several weeks the voltage diminishes because of deuterium leaking from the valves. They report no detection of significant levels of radioactivity or gamma rays.

They stress that they are not certain that the effect that they are seeing is fusion, but sate that “The apparent fusion reaction takes place in the junction between the semiconductor and the palladium powder. This produces an excitation which is transmitted to the electrons. This excitation increases their energy and allows them to cross the bandgap of the semiconductor and pass into the conduction band, as with a photovoltaic cell. The energy very quickly appears as a spontaneous potential difference, which can reach over 0.5 volt per junction.”

Unfortunately I am not sure when this paper was published. There’s no date on the paper, so it could be quite old. There is a live web site for Deuo Dynamics, and I will try to make contact with the authors to get some clarification on that.

Incidentally, Dennis Cravens demonstration of his brass sphere device at this year’s NIWeek conference was a purported LENR reaction with no energy input.

  • Cliff

    I think we are going to find that “the effect” is more common than previously thought and that there are a lot of ways to achieve it.

    • Roger Bird

      “the effect” might be an explanation for some unexplained failures in some certain systems where a voltage built up and screwed up a circuit and someone died.

  • Enea Romagnoli

    And to think that this research was presented in 2008 to ICCF 14
    I wonder if these two researchers did further advances

  • Pekka Janhunen

    They however write that they are not sure if it is cold fusion. They say that it produces microwatt power out of one gram of material. Over one year it would make 30 kJ/kg which is small in comparison to typical chemical energy release which can be max 16 MJ/kg or so.

    • Owen

      This line of research is just getting started. There’s room for massive improvement in my opinion. For instance, they’re probably not using Rossi’s secret sauce. The exact nano structure is likely not optimized yet by a long shot, etc. etc.

      • Warthog

        Indeed. In their ICCF14 paper they compare their output power density to that of the original Fermi fission pile at Chicago.
        With the advances in nanostructuring, scaling up the output power should and efficiency should be trivial. Imagine, a TRUE “fusion battery” with direct electrical output, bypassing the Carnot cycle completely. Their paper gives more than sufficient detail for others to reproduce/replicate the effect(s), and their test cells are certainly simple enough the pretty much any competent researcher can build examples.

      • Bernie Koppenhofer

        plus one

  • Owen

    It seems like the paper is fairly recent. From the Conclusion: “For nearly two decades, cold fusion researchers have tried to prove the existence of cold fusion…” That would put the publication date around 2006-2008 or so.

    This paper and the recent blog posts and comments here have boosted my confidence in the ability to produce electricity directly from LENR or something very similar. I hope Frank keeps digging up more info along these lines.

    What will Rossi call his new Electric Cat? Any guesses?

    • Roger Bird

      It may not get any name since it might be obsolete before it reaches the marketplace if the solid state LENR gets rolling.

    Without a demo or solid verification we are firmly in Sterling Allen territory here. (not that his speculative approach isn’t entertaining)

    Just the place for Cold Fusion Research, they just forgot to mention that.

  • Jim

    Duh, er, still don’t get it. Yes, kind of get the photon/electron solar panel analogy…but not getting source of the electric potential difference that creates the voltage. Deuterium is + charge, semiconductor is – charge? Knew I should have skipped beer hall for study hall that day…

  • Dr Bob

    Thanks for covering super conductors

    • Roger Bird

      Who are you thanking and where is the superconductor coverage?

    And Yet, it starts to take on the feel of a battery.

    Instead of charging it from the wall, you add Hydrogen.
    Similar but a different process from mixing chemicals together creating an instant battery.

    This is but a possibility of where this technology could eventually go.
    It mentions other material use possibilities. They should try Nickel.

    Note, this isn’t their day job. This is research apparently done on the side among several other projects.

    It’s lacking info: No mention of amperage & apparently no longevity data available at this time.

    No Heat, so a hydride material probably wont replace a hydrogen supply. Engineering problem. Self supply hydrogen as needed, thus no large tank for storing it. However with a small tank, this could provide cooking gas.

    Very interesting with many possibilities. Even joining this technology to a future multistage E-cat.

    • fortyniner

      Omega – “No Heat, so a hydride material probably wont replace a hydrogen supply.”

      Actually there are a number of unstable hydrides that decompose in the range 0C to 25C. Zinc hydride for instance decomposes at room temp and so would act to replenish hydrogen automatically.

      Rate of decomposition is inversely proportional to pressure and something like cadmium hydride (decomp @ 0C at 1 bar) might be used in highly pressurised (actually, self pressurising) systems.

      • Omega Z

        Thank you Peter.

        I wasn’t aware of the room temp hydrides, however now that you mention it, I do recall reading about hydrides that release under pressure.

        • fortyniner

          Yes, there is a whole range of hydrogen-releasing hydrides, and mixes could be selected with almost any properties needed to suit a reactor design. The beauty is that because the equilibrium point is determined by temperature and pressure, it is possible to produce any desired hydrogen pressure for a given temperature by making appropriate mixture choices – an automatic self-regulating system. Hydrides will also automatically replenish lost hydrogen, and the ‘nascent’ (partially ionised) form of the gas released may also be useful.

          It seems pretty likely that any system that uses hydrogen tanks now (SRI, DGT) will move to hydride sources before commercialisation, for safety reasons, simplification of manufacture and maintenance, and to increase the operational life of the cores.

    • Warthog

      I would suspect that they “are” trying nickel cells. Nickel is dirt cheap compared to palladium.

      And, as I recall, building the first Apple wasn’t the day job of either Jobs or Wozniak.

      I wonder if the company name “Deuo Dynamics” isn’t a tongue-in-cheek reference to the fact that they are a “two man” team (i.e. “dynamic duo”, which I think was a phrase originally used in Batman comic books for the “Batman/Robin” team).

  • LENRToday

    Whenever I read about these new LENR experiments performed by small teams, it makes me wonder – where are the Chinese in all of this?

    If LENR is a real phenomenon for producing energy (and I believe it is), should we not expect that an energy-starved industrial powerhouse to immediately throw teams of scientists into technology development? We have heard of a number of academic research efforts (Tsinghua University etc.) – but do we have any evidence of larger industrial activity?

    I remember Defkalion saying that the Chinese were the first through the door to license their technology – which seems a likely scenario if indeed Defkalion legitimately has the goods.

    I can only assume that behind the scenes, it IS happening in China. Do we have any Chinese speakers on this forum who have something to share – rumors gleaned from Chinese language sites or similar?

    I wonder how much time Rossi & Co. spend worrying about industrial espionage. No doubt his computer systems are prime targets for secret stealing – so I hope he has a reliable firewall in place!

    • BroKeeper

      In reflecting on this additional LENR potential I can’t help but envision another lengthy delay of a final commercialized E-Cat product release date (now 12 month testing) as Rossi and partner attempt to implement again and again new functionality from recent discoveries. The question is what and when is the breakeven point to maximize viability, profit, and social requirement/needs before China’s cheap versions are dumped on the market.

      My hope is he will release cheap E-Cat and E-Cat HT’s for home and commercial heating soon.

      Perhaps then followed ASAP in phase releases; Sterling-Cats, ZapCats, H2OCats, FluxCapCats, AntiGravCats, WarpCats, StarGateCats ……

      • Omega Z


        StarGateCat? Now you really have my attention.
        Time to get off this Rock.

          OK Wizard OZ now you’re showing your age. That was an old 60’s Star Trek episode. 😉 

        • GreenWin

          I of course approve, Omega.

    • Omega Z


      If one digs a little you find much is going on silently behind the scenes. Even by entities who claim it is not real or practical & claim not to have any involvement. Then you have entities like NASA who flip flop depending on who you talk to.

      I imagine some of this is due to caution, but mostly due to politics. they don’t want the attention at this time. It can cost them funding which is already scarce.

    • Sanjeev

      There was a presentation from China in iccf18.

      You can contact them to get more info. My guess is that a lot is going on there.

      • Roger Bird

        I sure hope that China is working on LENR. Also the Russians, but I doubt that they are. They have so much invested in nat. gas and oil.

        • Warthog

          There have been several Russian groups working that have presented papers at the various ICCF symposia over the years.

    • Kevin Huang

      You have said:”I remember Defkalion saying that the Chinese were the first through the door to license their technology”.I didn’t get any news.I am come from China.

  • fortyniner

    The same authors also seem to have been able to produce ‘heat bursts’ in plasma reactors ( also apparently in 2008. Unfortunately there doesn’t seem to be any mention online of any work post-dating ICCF14, and 5 years is a rather long silence. Perhaps admin’s email might produce some news.

  • tracy tynsky

    How do I invest in this?

  • nanonano

    That’s very interesting because now Andrea Rossi also reports that his unit the e-cat also
    produces electricity.
