OK, well and good. But you named a specific figure, saying it "can easily go above 400 deg C". I wondered if that was based on speculation and Rossi's imprecise assertions about the internal temperature of the device, or it if was based on something specific. It sounds like it's the former. (And I wasn't asking about whether the steam was pressurized -- it is perfectly possible to produce steam at 1 atm and 400 degrees C, just as it's possible to produce a stream of air at 1 atm and 400 C. Whether it's efficient to do so is a separate question.) (By the way, here's an example of a stream of superheated steam at 1 atmosphere: The exhaust of an oxyhydrogen torch. The oxygen and the hydrogen were under pressure, but the combustion product isn't.)
