Intensity or energy density is the first essential measure. A COP of 400 for an inlet energy of 1mW will have few applications. COP is a financial measure of the device- I am buying 1 kW of high currency electric energy to receive 6 kWatts of low currency thermal energy- not a very good deal. You are right that the temperature is also essential. Defkalion has attained over 650 C in the active core, Rossi seems to work at a much lower temperature. And the duration of the effect is also critical; one of the causes of the Rossi-DGT divorce ( in retrospect a very positive event!) was that the Ecat was not able to work continuously over 48 hours.
