Running a device for 4 hours as it cools off is not self sustaining. Self sustaining suggests that it will continue indefinitely since the energy required to keep the device hot and active is being generated within and Rossi has not stated that this is possible with the ECAT. As far as I recall, he speaks of a 50% duty cycle drive waveform at 1/3 output power level and I agree with him that this is required if he is to use a thermal control process. Can you show me any document where he suggests that the COP is not limited to approximately 6?
I was discussing Rossi's ECAT in my post and not the other researchers or systems with regard to self sustaining operation. Please read my post as I agree that some of the other electrolysis devices have been run in a semi continuous nature as they generate heat without drive. Rossi seems to have the best shot at a product in the shortest time to market. According to him, he already is selling the 1 MW system to a military customer and it does not run in a self sustaining mode by any reasonable definition. Maybe it is a good time to define what the phrase self sustaining means. My definition of this term is that a device that exhibits this mode will continue indefinitely to put out the same amount of heat without any input power required to drive it after initial ignition. Perhaps you do not agree with this definition? Also, we must choose a minimum time frame during which this constant power is generated if we are to ensure that stored heat or chemical heating is not the source of the energy. A few hours is far too short of a period if we are serious. And, in the case of Rossi's demonstration, the temperature of the device was drifting downward and not steady throughout the test.

Yes, he did. He ran for 4 hours with no input. Wrong. His cell wasconnected during this time. He claimed the connection was “minimal”or some such excuse - but no one ever got to test it. Other people at the demonstration confirmed there was no input power. However, if you doubt that, and you think Rossi bamboozled these observers, I suggest you ignore Rossi and look only at reports of heat after death from other researchers. People who distrust Rossi should ignore him completely, and look only at other cold fusion research. Rossi has made important contributions in my opinion, but you can ignore him and still learn all there is to know about this field by looking at other researchers. - Jed
