There are gradients in a pot of hot water and it is hot near the bottom, but the water moves around pretty quickly. That is one of the things I observed calibrating the thermocouples the other day. There are larger gradients in ice slurry, unless you vigorously stir it. > When you have boiling water inside plus some headspace filled with steam >> (like a mostly-full teapot), then you have some space to work with and you >> can increase or decrease the power to lower or raise the water level.

I meant only that when it is fulling up, the cold water cools it somewhat, but when it is full, not only does the cold water cool it, but a nearly equal volume of hot water leaves. If flow rate is 5 ml/s, it is as if you add 5 ml of cold water and then remove another 5 ml of hot. Perhaps this does not make much difference, depending on the total volume. > Further, we have no evidence that power is "increased or decreased" in the > later demos. Well, Rossi is changing the power when he twiddles the controls. Maybe he is trying to keep it stable. But anyway if it overflows I am pretty sure he turns up the power. - Jed
