Yes, I know. I pointed that out. Please note that the exposed surface area of the 12 kW hot water heater must be considerably smaller than that of the Rossi cell. Bear in mind that a hot water heater manufacturer does not make a device that works on the ragged edge of safety, close to melting. In other words, this heater can probably transfer twice as much heat, at a much lower flow rate than the maximum 19 L/min., without self destructing. > With a tubular reactor as described in the Rossi patent, there is not > enough surface area to provide heat transfer through stainless steel to a > straight-thru flow of cold water to transfer the level of heat claimed. > Similar stainless steel surfaces in teapots transfer heat at roughly this rate without difficulty. > The 130 kW is physically impossible. > Nuclear and combustion fired boilers transfer heat at approximately this rate, with fuel rods, fire tubes or water tubes. As I mentioned these tubes and fuel rods have larger surface area per unit of volume than Rossi's device, but on the other hand they can probably tolerate much higher rates. - Jed
