As far as I know, the record for Pd-D is 294 MJ, Roulette et al.: http://lenr-canr.org/acrobat/RouletteTresultsofi.pdf Good information to contrast here, Jed. Roulette was basically seven excellent experiments, of low power input, of which 5 failed with little or no gain, and which ran for a long time – up to152 days… and the one with big net gain did not see any excess energy for the first 60 days. Fig. 7 of that paper shows that the average gain at about one watt, which is confusing as it should be more. Mizuno/Yoshino was basically a 75 watt gain experiment that saw gain from start to end, and ended after 30 days due to fuel depletion. Average power gain was apparently a factor of 70-75 times more than Roulette, but it ran for far less time, so net gain was less. If Roulette (run 3 and run 4) had been considered to be the “hero” results for LENR cold fusion prior to the MIT presentation of Yoshino, there is no doubt that it does not compare favorably now. BTW helium is not mentioned in Roulette and was not found in Mizuno. Roulette #3 had a COP of 1.5 and amazingly ran for two months before showing any gain. Together with the other failed runs, there is little indication of a route to commercialization. In contrast, Mizuno shows a clear path, and in fact Yoshino showed pictures of two significant reactor upgrades already being fabricated in Japan. There is great anticipation that the multi-kW unit of Clean Power could be in testing now. This would be the kind of information which should get people excited, since it fits in with both Mills and Rossi, and with three positive paths, we can be much more optimistic. Actually, if it were a horse race, I’d put Mizuno at the top of that trifecta since he is the only one with real data. In conclusion, future historians may differ – but when we are talking about deuterium LENR, it appears to this non-historian, that everything from 1989-2014, prior to MIT could be considered to be of a different era than everything after 2014. The Yoshino presentation could have been that much of a paradigm shift. Time will tell, but where is the excitement level which should accompany such a dramatic change in technology ? Sadly, it is missing. Jones
