No, the metal is certainly >100C (I think alot greater). With no power added it should cool according to laws of conduction and convection. Yes, after the power is cut the metal does not get hotter, it cools- toward 100C. As heat is transferred from metal to 100C water the water will boil creating steam. It will do this for as long as the metal is cooling (relative to 100C). This should gnot be compared to an uninsulated pot since there is conduction convection & radiation acting in such an experiment while the E-Cat is well insulated and would not have the same time constant as a pot on a stove. As for an experiment I just turned up my electric stove (the small burner) to High until there was a dull red glow. As of 20 minutes after I turned the power off it was still able to produce steam when a drop of water was dropped on it. You should not underestimate cooling times. Kilns can take days to cool. The question is what is the time constant for an E-Cat and is the flow turned off when he does the test or not. Remember there is only 2g a sec of steam being created when the water is flowing. You should be able to see that the power off test could well produce steam for 15 minutes with the thermal mass of the E-Cat. ----- Original Message ----- From: Jed Rothwell To: vortex-l@eskimo.com Sent: Thursday, August 25, 2011 4:58 PM Subject: Re: [Vo]:The Krivit Videos Part 3

If the metal is below 100C to start we never get boiling so of course its above 100C (by alot) and will cool to 100C which is the temp of boiling water. I still don't follow what you have in mind. Take the metal at the bottom of a pot on the stove. It is much hotter than 100°C because it is over the gas flame. You turn off the flame. The metal does not get any hotter. Boiling continues for perhaps a minute. But the temperature of the metal and the water cannot rise. If it was not driven above 100°C while the gas was burning, it cannot get any hotter than that after the flame goes off. If we assume there is no anomalous heat in the eCat, the only source of heat left is the joule heaters inside and surrounding the cell. It is conventional, like a gas flame. The heat does not transfer from the metal to the water any faster when the heater power is turned off. As soon as these heaters are turned off, everything in the cell must begin cooling down. A high temperature in a well insulated cell might be sustained for a while. Perhaps longer than with my stainless steel pot. But it cannot get any hotter than it was with power input. Also, boiling removes so much heat, so rapidly, that a few moments after you turn off an electric or gas heater the boiling will stop. Continuing for 15 minutes is out of the question. You would have to have a gigantic mass of hot metal to maintain boiling and release that much heat. - Jed
