Yes, a COP (coefficient of performance) over 100% is technically impossible (an IC engine will be 25%-50%, electric around 80%). That’s not what they really mean. Every science has its own language. In LENR the input is chemical energy and the output is “unknown” but presumably nuclear fusion occurring at low energy levels. So outputs are often quoted from 4 to 20 times the inputs, or COP 4-20.

According to Wiki, COP is a measure applied to heat pumps. Are these scam contraptions heat pumps?

LENR is definitely not a heat pump. COP is general term used in physics to measure the efficiency of an energy conversion process (as in a heat pump). It’s the ratio of input energy to output energy.

As LENR/Cold Fusion etc being a scam. It’s possible. I used to think it was, but I’ve read just about every single piece of data for the last 4 or so years. I think it’s the real deal. For it to be a scam, 100’s of people would have to be in on it now, going all the way back to Pons and Fleishman. With so many people in on it, and based on what I’ve read, I’m inclined to say something is there. Time will tell.
