The water is being pumped in at a steady rate, horizontally, past the reactor. Depending on the temperature of the reactor the water is heated to varying degrees. If the reactor temperature is high enough, it will heat the water to the boiling point. If it is still higher, some of the water changes phase, and if it is high enough, all the water changes phase as it passes the reactor. If it is heated beyond that, the steam increases in temperature. Here's the implication of the wacky idea you suggest. You claim all the water is being vaporized, and that corresponds to almost 5 kW power. Then you suggest that if the power drops a little and the water "overflows", the temperature of the water goes below the bp. When the water is below the bp, the power transfer is about 600W. So you are suggesting that the power is oscillating between 5 kW and 600 W. How is that possible? > That's what happens with other experiments close to boiling with flow > calorimeters.

He just has to reduce the flow rate. And why is the bp of water a magic temperature that the ecat can tolerate, and not a few degrees more. It's all too convenient for his con, if you ask me.
