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.

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.
