Even at a COP of 6 gas heating would be better than electric when overall system cost is considered. This is because gas is so cheap these days.
Can you show where Rossi has declared that his delivered COP is guaranteed to be less than 6? I have never seen any reference to a number less than 6 from him.

My question is though if they can use gas, why not use a self-feedback system.

My simulations suggest that the geometry of the device can be adjusted to achieve a higher COP if required. We need to realize that the testing done by the scientists was not conducted in a manner that optimized the COP and they stated that in their report.

If you look at his hotCats, they are being configured as industrial furnace heating elements. Operating at >1000C, these furnace heating elements being replaced are mostly electrical with a COP=1 (as Bob Greenyer showed, some are gas). A COP=3+ heating element for these industrial furnace applications will save a lot of money and coal because coal is being used to drive the COP=1 furnace elements today. I think the biggest expense for some of these large companies that use heat treatment is the energy cost and I think a COP=3+ for a T=1300C+ furnace element will sell well. There are no heat pumps in such a high temperature application to compete with. In China, pollution is so bad that the real cost of coal is high. The money appears to be in heat at the moment, not in electrical production. It is 28F here this morning and we just had our first dusting of snow. I could really use a nice COP=3 heater. In cold weather climates, even cold weather optimized heat pumps don't operate with a COP over 3. There would be a nice home market here.

If coal is so cheap, than a cop of 3:1 for electricity -> thermal isn't going to cut it. They're are going to need to be able to power the cat by coal itself or gas and get a 3:1 thermal -> thermal ratio.
