Don't you mean it would rapidly cool below 100°C? Not "toward" but below. It can't get any hotter than 100°C, or it would already when the power is turned on. I think thermal inertia (total heat capacity; heat released from metal above 100°C) cannot explain continued boiling. Metals such as the steel and nickel catalyst have specific heat about 10 times lower than water. There is only a tiny bit of hydrogen gas; much less than 1 g with negligible thermal mass. So nearly all the thermal mass is in the water. Since the steam production continued, they must have left the pump turned on, and new water flowing in. Based on this, I predict that without anomalous heat the boiling would stop within a minute and the temperature would begin falling rapidly. As I said, even if there was some metal or nickel powder much hotter than 100°C the thermal mass of the hot metal is much lower than the water. I base this partly on tests I have done lately with pots of boiling water with approximately as much mass as a large eCat, I used a large, heavy pot with metal that was much hotter than boiling; it continued to boil for several seconds after the gas flame was turned off. After the first minute the temperate began falling several degrees per minute. In 15 minutes it would far below boiling, especially if the water continues to flow through. I think I uploaded a photo of the pot here. It has some small holes in the lid, convenient for the thermocouples. The steam escapes from them. - Jed
