One report I read was that the 'used' sample had copper in natural isotope ratios, which I would not really expect (though I'm not an expert). It seemed like a troubling detail to me. Can anyone more knowledgeable comment on this point?

I've not seen any smoking gun or explanation of how they could be faking things with the E-cat demonstrations, but it is not impossible that it is a well-planned scam either. So I'm hopeful, but still waiting for the demonstration reactor in Greece or for fully independent lab verification (or a teardown of a unit after seeing it function), to really jump on the bandwagon.

Yeah. I’m no expert either, but apparently the nickel is picking up a proton by fusing with hydrogen, thus becoming copper. And necessarily releasing huge amounts of energy while doing so.
