While many speculate on fraud and incompetence of the various observers, no one can show fraud or incompetence on the part of the observers. You have all concluded that since you can't explain it or don't like the possibility, it can't be happening. Many on this board are the self-appointed final arbiters of what is possible and what is not possible and there is a mob mentality of attacking that which you do not understand and those that point out that you don't know what you don't know. Most amusing. You say that there can be no fusion [maybe there isn't] without 500+kev gamma. Rossi says that there is low-level gamma and neutrons. A more measured commentary is a draft google document at

This shows points and counterpoints. While Rossi and Defkalion may not have not proved their cases, no one who claims fraud has proved theirs, either. A few of those were memorably ludicrous such as the 30kW of beamed microwave radiation that must have been powering an earlier version of the ECat. "Guiseppe, si sta facendo caldo qui." Caldo, indeed.
Consider that Rossi may actually have what he claims and that a rush to judgement may have you eating crow cooked by an ECat. Be patient and all will be revealed....one way or another.
