That is a true statement. As for the rest of it, I don't know what to say except that my comment was directed at the absurdity of saying that you can create 10 megawatts of energy out of 1 megawatt of energy. Your example is ignoring at least one of the inputs, in this case some sort of change in the energy state of the nickel powder, perhaps at the nuclear level. I don't know where the excess energy comes from, but I know it does not come from thin air.

Indeed you cant create energy out of nothing, however a heat pump can have a coefficient of performance as high as eight or so under ideal conditions. The difference is of course that they only move heat they don’t make it. They can move it from a low temperature source to a higher temperature output.
You have mixed the context of the discussion. We are talking about a fusion device that requires electricity for internal pumping and preheating. There were people happy if the machine could put out ten units of heat for one unit of electricity. We are discussing fusion not over unity devices.
