There are at least 5-10 different kinds of old and new stirling engines available with 30-40% efficiency using 7-800°C input temperatures. They range from 100W-30kW in capacity. So no problem doing a self-driven system with LENR COP of 3.2 Qenergy probably easiest to get a hold of (around 33%,

Rossi had now shown that he can get COP3. Why doesn't he use that and build an ecat out of that? Show it inside a black box with some extra output, say 500W for several months. It will certainly destroy any doubt concerning his invention and will not reveal any trade secret he has. -- Daniel

I don't know why Rossi doesn't do this. I think he must hardly have any ingenuity - or the scientists/engineers that are in a position to advise him! (Or you could think of more insulting terms). To convert the output heat to electricity, and then convert it back to input heat would have to

Did you read/understand Paul's analysis? This is impractical and maybe impossible unless he can improve efficiency. Carnot conversion just isn't great enough to turn the heat into usable electricity. On Sat, Oct 18, 2014 at 3:24 PM, jwin...@cyllene.uwa.edu.au wrote: I don't know why Rossi

Active cooling would work as well as active heating so you don't need to worry about carnot efficiency. Start it up and then keep it just hot enough by pumping a liquid, under controlled rates, with an appropriately high boiling point and decent specific heat and conductivity through the system
