Heating the constant flow of cool water (at 1 g/L) to the boiling point consumes 300W in Lewan's experiment. That can be calculated. That leaves 2.2 kW for steam production, to be compared directly with the video. Even if you consider the two plumes to be similar, Lewan's claim is at least a factor of 2 too high. 2.5 kW is not very much possible. But the plume in Lewan's video seems far smaller than the in the kitchen video, meaning that a small increase in the power by Rossi when he is off-camera can easily explain the observations. The thing about the 4 or 5 or 10 kW claims is that they make faking it much more difficult, because ordinary mains circuits don't usually supply that kind of power. Once you reduce these claims into the kW or few hundred watt range, then some simple power or flow rate misrepresentations is all it takes.

The stove design has nothing to do with how much heat is captured by the pot. You can see the heating element. That means IR is quite clearly escaping. Look at the trouble Rossi went to to insulate his ecat, so that all the heat went in to the water. In the kitchen video, heat escapes before it enters the pot, and the pot itself is not insulated, and quite large, and will also lose heat.

In the write-up, they say they produced both dry and wet steam.
