I should point out that Krivit sent me another message saying: "If you can remind me of some common examples of periods of *excess heat in the range of Watts last for hours *I would like to correct my text thank you."
That is somewhat rarer. I pointed to the F&P heat after death event which was 100 W for several hours. I also pointed to Storms' histogram showing that there are examples above 1 W. The examples in this graph all lasted longer than a few minutes. They all amounting to heat energy beyond the limits of chemistry, or he would not have listed them. A transient heat effect lasting a few minutes does not count. - Jed
