Some interesting information was given by Andrea Rossi today on the Journal of Nuclear Physics regarding the smallest size of the E-Cat.
Herb Gillis asked Rossi what his understanding was regarding the smallest possible size that an E-Cat could be.

I talk only of what I know and have experienced: so far the smaller is 1 kW power. The amount of charge can be about 1 g.
My guess is that Rossi here is referring to Hot Cats that he is working on while he watches over the 1MW plant in his shipping container. He has said recently that they have had success improving the COP of the Hot Cat, by some ‘ingenious’ method. Since we learned today that in the 1MW plant Rossi’s team has been able to increase the COP by driving some E-Cats with others, I would expect that they have been trying something similar with the Hot Cats.
The fact that Rossi is able to drive one E-Cat with another implies that the heat from one E-Cat can stimulate the reaction in another — but there could be some other EM or RF stimulation involved.
I think this is the smallest size E-Cat that we have heard Rossi say he has worked with, and it could be that working with smaller reactors is the key to improving COP because of the apparently successful ability to have them power each other.
