Always? ... doubt it. There is no evidence from Mizuno of helium and it makes no sense to be dogmatic on the issue until evidence arrives. Which is to say: until we get mass spec readings for significant amounts of helium after a long run, fusion remains just a fall-back assumption based on old electrolysis results - and possibly unjustified for anything else. Surprisingly, even with a reactor operating at 3 kw for extended periods - there is no report of tritium or transmutation of any kind. Mizuno is reportedly an expert at radiation detection so the lack of any mention by him is curious, to say the least. Even if the branching ratio of LENR in general favors mostly helium - at this high level of output there is little logical way to claim that absolute quenching of the normal branching ratio all the way back to zero tritium; and tritium could not be missed by him in small amounts, if it was present. Home usage of the reactor almost guarantees he assumes no tritium even at very high thermal output. He would not jeopardize his family's health. I agree that most of the LENR experts think deuterium fusion is responsible for the excess heat, but as of now that seems like little more than speculation to me - especially since in the earlier runs at 4000 Pa, with only protium as fuel (but with rubbed Pd on nickel), more excess energy was seen with protium-- than with deuterium under the same conditions. This favors a non-fusion modus operandi. Jones
