The discussion by Rossi of powering the device for 1/4 of the time during which the COP is greater than 1 and then letting it run in a self sustaining mode for the other 3/4 of the time is fairly consistent with my heat controlled model. He has maintained this position for a couple of years now so I believe it is true. He needs a duty cycle of this sort in order to obtain an overall COP of 6 +. This is also evidence that he is pushing the device fairly close to the thermal run away region which is necessary for the high COP performance.

It has been 2 years since the October, 2011 1MW demonstration which ganged up a bunch of "appliance"-scale devices. That was in Italy. I believe he means there are certifications approved in the U.S. Two years to accomplish this would be lightning fast, for a device as radical as this. Frankly, I can't imagine how it could be done. Maybe the people testing it do not think it is a nuclear device? I think the approvals are only for industrial users, not for home use. I believe safety standards for consumer-level appliances are more demanding than for industry. I mean that many machines in factories are dangerous, and would not be allowed in houses. In industry you assume that trained experts will operate the equipment. This device is far different from the modules of the 1 MW reactor. It would have to be re-certified from scratch, I am sure. I have some doubts about Rossi's claims relating to business, but his previous technical claims were confirmed by ELFORSK. I expect his present technical claims will also be confirmed, such as the surface temperature of 1,100°C and 40% Carnot efficiency. I have heard that he really is working with a major U.S. corporation. It sounds like it is going well. This is excellent news. - Jed
