Second Krivit was not quantitative about the power he thought the output steam represented. He was merely questioning the conclusions because no evidence of steam dryness was provided, and claimed that the liquid content of the steam could change the claimed excess heat by *as much as* 2 orders of magnitude. > 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).

With the chimney filled with water, the height will produce an increase in the bp by a fraction of a degree. With pure steam, the pressure required to get through the various fittings, expanders, reducers, and elbows could cause a similar fraction of a degree increase in the bp. What happens in between is pretty hard to predict, but the fact that the temperature is very flat shows that from the very onset of boiling (at 600W) the pressure is pretty constant. > Overall, I think that Rossi has adjusted the water inflow such a way that > more than 60% of water goes through phase change. > This represents a major change in your thinking. Until yesterday, you insisted that the output had to be at least 95% dry steam. Nothing else was possible.
