This is probably correct analysis. I think that this is possible to calculate fairly accurately, if we know the diameter of opening for the hose. As boiling point of water inside E-Cat is what is measured with the probe, then we can deduce the pressure inside E-Cat, because steam pressure contributes mostly for total pressure, because backpressure in the hose is essentially zero due to gravitational downhill (at least with Lewan's E-Cat where water went to the blue bucket at the floor.) We need some 600 wats for heating water inflow to boiling point. Then we can calculate how much power we need to increase pressure inside E-Cat to explain elevated boiling point. My gut feeling says that we need extra power some kilowatts, so there is clearly extra heat present. This clearly falsifies Krivit's criticism by one order of magnitude as he assumes that there is just few hundred wats for generating steam and elevating the pressure. To confirm this hypothesis on E-Cat, we should have strong correlation between alleged power output and measured boiling point (we have the same hose in all demonstrations). That is, because pressure is directly proportional to amount of generated steam. Overall, I think that Rossi has adjusted the water inflow such a way that more than 60% of water goes through phase change. Here I again refer to Lewan's famous blue bucket and estimation that condensation is quite significant, because steam keeps water in the bucket at 99.9°C for a 3 hours, so lots of cooling will occur there during the test. —Jouni
