These test results are indeed difficult to explain. I have one question to those who have some or partial expert knowledge on steam engineering: Does they use superheated steam or steam that is at boiling point of local pressure? My guess is latter of course.
However, I cannot explain 130°C temperature if assumed low pressure inside E-Cat, because specific temperature of steam is just too low so that it could produce such a smooth temperature graph. E.g. input power cut off should cause huge bump into graph. Smooth temperature graph should be only plausible, if steam temperature is regulated by the boiling point at local pressure. But for 130°C/170 kPa pressure requirements are quite high, higher than in autoclave, although it is not out of question. Also 5 kg/h water collected from outlet, is consistent that 60-80% of water was evaporated, just like previous e-Cat experiments (excluding March experiment). This would support the idea that steam temperature is regulated by boiling point temperature at local pressure. Could someone calculate the size of orifice for steam exit, to explain 130°C temperature corresponding 170 kPa over pressure? If it is assumed that E-Cat produces steam in ca. 9 kW total power. Using previous E-Cat demonstrations as reference, it should be quite small, just few millimeters. Unlike what Mats Lewan estimated, I think that it may be big enough to enable water to overflow, as pump pumps water with sufficient pressure. Also I have not yet carefully studied the data, but I would guess that 170 kPa over pressure could explain why the water pumping rate was decreased after E-Cat started operating, because pump pumps water only with 300 kPa pressure IIRC. But, this seems more plausible 1MW production plant. I think that later development can boost individual module output power at least few orders of magnitude. It should be possible, if sufficient cooling is arranged, that there is 1 GW power plant fitted to the similar sized container. Anyways, my confidence for E-Cat has increased somewhat due to this new experiment. This really is starting to look commercially viable prototype. This would also decrease the main problem with Rossi that he chose very irrational method for bringing this cat out of the closed. He really seems to be ready to go directly into market without spending lots of public resources for R&D. –Jouni
