Rossi has been asked another time about drive during the self sustaining mode and confirmed that it is required for safety reasons. Check this question and answer. http://www.journal-of-nuclear-physics.com/?p=748&cpage=3#comment-365011 and http://www.journal-of-nuclear-physics.com/?p=748&cpage=3#comment-365064. With this response there can be little doubt that what he refers to as SSM is really a duty cycle input drive waveform as I have suggested on many occasions. In his journal, he points out that the Hot Cat SSM periods are typically 1 hour. My interpretation is that the drive lasts for about 1 hour and then the device drifts for another 1 hour. I admit that he is elusive in explaining the actual operation of the device.
Also, Rossi continues to quote a COP of 6 for his product. Read this link: http://www.journal-of-nuclear-physics.com/?p=748&cpage=3#comment-365306. This is for the Hot Cat contracts even with the latest reported data. I do not consider this a problem at this point since it makes sense according to my simulations. Of course I would like to see evidence of a larger COP, but with the high temperatures now being produced it is obvious to me that he should be able to connect his device to a generator of some type and have sufficient electrical power available for the drive and plenty left over. At one time gas heating was suggested by him, but that appears to be left out of his postings now. I am not sure why this is so. Dave
