Dave, In selfsustaining mode, there is no input power to the cylinder. So I don't understand the 3 first sentences of your email. Self sustain mode is no input power and you say 2.359 kW. Duty cycle is 118/328 = 0.359. Time when the system was not in self sustaining mode is 328-118 = 210 hours. Something is wrong about the total energy consumed as claimed by Rossi. If total energy consumed is 278.4 kWh and 210 hours of non self sustained mode, the average power consumption is 1.32 kW, not 2.4 kW as said in the report. If we take the total time, things go worse ... Or am I missing something ? Arnaud

My quick analysis reveals that the true COP in the self sustaining mode is in line with his earlier statements. If you take the total input energy during the self sustaining mode (278.4 kWh) and divide by the hours in this mode (118 Hours) you get 2.359 kW. This matches his average input power listing of 2.4 kW. And it is likewise stated that the peak input is 5 kW. This matches my simulations fairly well where the duty cycle is at 2.359/5 = .4718. The output power is stated as 14.337 kW. If I use these numbers I calculate the COP in this mode as being 14.337/2.359 = 6.0775. Note also that the peak power output to the peak input is 14.337 / 5.0 = 2.8674 which is in line with his previous statements that this ratio is 3 to 1 in his design that also is in line with my earlier simulations. These numbers are consistent with what Rossi has been telling the world for a long time and my simulations support the numbers when temperature control is applied to my simulated device. Perhaps this time we have the proof we seek if the numbers hold up to scrutiny.
