I do not think they actually saw the steam emerge directly from the chimney. Many people have asserted that the two meters used in these studies do not measure by mass, or that they cannot combine this measurement with the temperature to measure enthalpy. They are saying the manufacturers of these meters are wrong, and Galantini are wrong. I doubt it. In any case, the second test proved that the steam is dry. All other discussion is obfuscation, handwaving, unfounded accusations of fraud, and a waste of time. By the way, I have seen 30 kW of steam emerge from a pipe about 1 m from the steam generator. It is impressive, but the plume is surprisingly small. The vapor is visible ~30 cm from the end of the hose. Wet and dry steam generators at dry cleaners are not that large. They are 2 to 5 kW. Here is a photo of a 5 kW wet steam stream: http://www.chewinggumremovalmachines.com/wet-steam-gum-removal-pressure-washers.php 1.5 kW steam cleaners for home use are common. They do not produce an impressive plume. This looks like ~2 kW, used to clean an automobile interior: http://www.youtube.com/watch?v=5_pcOgkRbfQ&feature=related http://wn.com/ICanSteamCleanwow - Jed
