"Compared to hydrogen gas as the experimental control: 15°C increase in purifier temperature consistently seen with D2 that was not seen with the H2 control when gasses were unloaded from the purifier." Yes, this raises a number of continually neglected, or misinterpreted points. Is there a rationale underlying the apparent conflicts below ? To summarize most (but not all) experiments using different metals and either Ni, Pd, or alloys with either protium or deuterium: 1) Palladium works well with deuterium, but not with hydrogen. Does not need to be nano, but micro cracking helps. Hydrogen has been used as a control. 2) Nickel alone works slightly, or not at all, with either D or H, but when reduced to nano works better with hydrogen than deuterium. 3) Nickel when used with a catalyst (Thermacore) works well with hydrogen, even when non-nano. Deuterium was not tried AFAIK. Thermacore reported about double the heat per unit of surface area that Rossi reports. 3) Nickel can be both alloyed, especially with copper, and reduced to nano and THEN will work MUCH better with hydrogen than deuterium. Rossi claims to quench the reaction with deuterium. These findings are not necessarily in conflict when you consider the vast differences in physical properties between deuterium and hydrogen. Otherwise, palladium and nickel are very similar in properties - and the vastly increased surface area of nano makes a huge difference with nickel. This may indicate that Ni-H reactions are surface reactions, where as Pd-D is not as dependent on maximized surface, but it helps. Jones
