I stand corrected in this case. Of course I do not think that the ECAT is some form of heat pump, but the total demonstrated effeciency is close to that of a heat pump. Why buy a new technology that merely replaces a reliable one currently on the market? By comparison, DGT suggests that they demonstrate a device that far exceeds the performance of any form of heat pump.
I was mainly expressing the concern that it becomes increasingly possible to muddy the water regarding performance as the level of gain drops. At some level it becomes impossible to regenerate the electricity required to make the device operate. I have not calculated that value, but I suspect it would be between 3 and 6 at the output temperature of the ECAT(120 C) that has been demonstrated. Perhaps some of the collective members have performed that calculation and might show their figures. There is no heat pump theory requirement that prevents them from working at the hundreds of degree temperature levels as far as I know. This is an operating fluid characteristic. We use the standard fluids today in home systems based upon our comfort levels and the atmosphere, not limited by theory. I suspect that there are industrial applications that operate at far higher temperature levels. It would be interesting for vort members to make a list of the ones that they are aware of and their modes of operation.

No, it is not. It is light years away from the performance of a heat pump. There is not the slightest chance it is a heat pump. The reasons are simple: 1. A heat pump transfers heat from one place to another. One location gets warm, and another close by gets cold to the exact same extent. There is no doubt the Rossi device is producing kilowatt levels of heat. So, if it is a heat pump, it has to be cooling down air, water or metal to the same extent it heats up other water. It has to extract that heat from the surroundings. If that were happening you would see water freeze. The metal would be covered with a thick layer of frozen condensation. The surroundings would be very cold to the touch. The intense cold would be as obvious as the intense heat is. Nothing like that has been observed. The device is small and the entire thing is hot. There is no flow of water that goes in at room temperature and comes out icy cold. That scenario is physically impossible. No heat pump that small could work that well in any case. If Rossi has invented such a thing, it is as revolutionary as cold fusion. 2. No heat pump can produce such high temperature difference. Some of the best ones move ~6 times more heat than it takes to operate them, but only when the temperature difference is slight; a few degrees at most. Above 10 degrees efficiency falls off drastically. None can produce temperatures in the hundreds of degrees. Again, if Rossi has devised a heat pump that can do this, it is gigantic revolution in physics. - Jed
