Problem with that there is only one data point, and you have no way know whether the system was in equilibrium or not or if the power production was constant or not. And certainly power production could not be constant, because electric power was cut off in middle of the run. Also if system was not in the equilibrium, then high water flow could tell that there was bubbling of water more than usually when measurements were made, or that water level was below normal level so that there was less water than in equilibrium. Therefore more datapoints are needed for further conclusions, but we can only use this single liquid water content measurement for calculating enthalpy when steam temperature was 118°C. There is extremely long way from 118°C to 133.7°C if you are going to go there via increasing steam pressure. > Lewan told me that Rossi insists that there are no internal obstructions > to the outlet which would cause the internal pressure to be significantly > above 1 atmosphere.

For me that steam plume looked something like 20 kW worth of steam as there was released 2.6 MJ (20°C) worth of thermal inertia just in few minutes. It was nothing like my 1.5 kW steam cleaner would output. But I think that there is misunderstanding. For me Lewan told that he asked about if there is pressure release valve in E-Cat? This would make very much sense, if E-Cat does operate in high pressures. This is something what Rossi denied, therefore Mats concluded that E-Cat does not operate in high pressures, but I think that water inlet valve acts like a pressure release valve, therefore there is no need for separate valve. –Jouni
