> So in a sense the elimination of fakes is cumulative. Bear in mind that when Rossi says he has something he tends to follow up on it. (Maybe not exactly as promised, but close to it).
Let's accept for the moment the OUTPUT analysis : it DOES produce the documented COP. Electrical INPUT is a two-edged sword. It can be measured to 6 decimal places .. IF you do it correctly, but if you don't cover ALL bases you might miss something. (eg an AC-only meter might not notice DC, or HF AC beyond its spec). But Rossi says he has a GAS-POWERED eCat. I believe him: ANY source of temperature stimulus will do. It's rather hard to modulate/cheat a GAS meter, though the actual INPUT power delivered might only be known to ONE decimal place.
