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
