Status Report on Alan Smith’s HHO Experiment

Here’s the latest from Alan Smith who is getting ready to carry out an experiment (sponsored by kind donations from E-Cat World readers) to try to discover if there is any excess heat generated when HHO gas is recombined in a catalyst like those found in a catalytic converter for an automobile.

I now have the last pieces of the jigsaw — all the polycarbonate, a toughened glass combustion chamber, the thermometers, silicon rubber gaskets and electrolyzer stainless plates, even an aluminium water bottle I found in the local £1 store which can be made into a very adequate gas drier.

By the end of March I shall have finished my current tasks (by dint of working overtime) and be able to begin construction of the components. Although I can’t start the build till then, I find my thoughts (and my YouTube e visits) increasingly turning toward the best designs for each of the component parts the experiment requires.

Some of you may have noticed my email reprinted on Peswiki regarding Sterling’s wish for a ‘rough and ready’ experiment to determine if HHO could yield OU. I was very pleased when the guys from SRI agreed with my misgivings about his methods. Rough and ready will never do when we are talking (possibly) about a truly hot potato like benchtop LENR.

    Is known what active elements are used in the catalyst? (Rhodium/Platinum is the most obvious, in older palladium is used and sometimes cerium).

  • Justin Church

    Great to see you have finally managed to get the pieces of the puzzle together and in order. We look forward to your work and results.

  • Obvious

    I was thinking that a piece of catalyst would be a good way to prevent evaporative heat losses under control in a F&P type cell, and shortly after noticed that there seems to be one in McKubre’s cells. I wonder how they contribute to or affect the results. Perhaps SRI knows more about this than we realize.

    Thanks for your good work, Allan. I’m looking forward to the results.

    • Andreas Moraitis

      The different results for H2O and D2O support the hypothesis that there is more than a chemical reaction. D2O is chemically somewhat less reactive than H2O. (That’s why you better shouldn’t drink it.)

      If Alan’s experiment is successful, Frank could start a second funding campaign in order to get some deciliters of heavy water. I would also recommend trying a nickel catalyst. If there is really some LENR effect (at the moment, still with a big “if”), nickel should give better results with the light water than Pt/Pd.

      • Andreas Moraitis

        Slight correction: The circumstance that D2O is chemically less reactive than H2O must not necessarily mean that the recombination of deuterium with oxygen occurs slower than the recombination of light hydrogen with oxygen. But even if the reaction rates were identical, the diagrams wouldn’t leave much doubt.

        Justin (if you are around): Testing heavy water could also be an option for you.

        • Justin Church

          I have been curious how the experiments would fare by electrolyzing highly concentrated heavy water but that is not something I can easily or cheaply get my hands on. I’ve often wondered how much if any deuterium or tritium is concentrated out inside my own cell designs. I just don’t have the equipment to analyze the water or gas for these isotopes. I know you can concentrate out heavy water using electrolysis just takes a long time and multiple units running. I could see a solar heavy water concentration unit being of great use.

          • Andreas Moraitis

            You’re addressing an important question. I don’t know the reason for the enrichment of heavy water in electrolysis, but I guess that splitting D2O requires more energy than splitting H2O. If this is true, the recombination of deuterium and oxygen should release additional chemical energy, which could be misinterpreted as atypical “excess heat”. However, I may be wrong with these assumptions.

            The ratio between light and heavy water in a mixture that doesn’t contain significant amounts of other substances could be determined roughly by measuring the density: D2O is about 10.7% more dense than H2O.

      • Obvious

        If D (essentially extra neutrons) is critical in the wet cells, and He is the product, then I would expect something in the order of 146 times as much He produced in D2O cells than plain water.

        I am wondering if in some “blank” runs from SRI there may be some data on recombining by catalyst compared to other blank runs, depending on what part of the apparatus was changed to make it a blank/intentional non-reactive cell.
