Did this guy try to scam you in some way ? Did he ask for money publicly from someone ? I ask this because to me there is a weird dissonance between what this "inventor" says and how people react. He basically said that he discovered a way to generate excess heat (there were some public demo but whatever, I was not present) and he does not want to divulge how but he will try to mass produce it. And the reactions to this: "he's a scammer, he has no patent therefore he's a scammer, oh he has a patent ? still scammer. patents prove nothing" and so on. I have no horses in this race but shouldn't we call someone a scammer AFTER he tried to scam or scammed someone and not BEFORE ? And BTW why so much passion around LENR, E-CATs, "cold fusion" and so little relaxed "I believe it when I see it" ?
