There are also gradients in pure dry steam. Always at or above the bp. But there are no temperature gradients in a mixture of steam and liquid water, as long as there are no pressure gradients. A homogenous mixture (smallish drops) will be at the boiling point, and such a mixture is to be expected when you produce a gas orders of magnitude more voluminous than the liquid in a confined volume. > > 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. > And when it is boiling an equal mass of steam 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.

The rate of cold coming in, hot water and/or steam going out. At the bp, a slight change in power is simply accommodated by a change in the ratio of steam and water. > > Well, Rossi is changing the power when he twiddles the controls.

Because he certainly claims not to in all but the January demo. If we both agree he's dishonest, then there is no reason to believe he has invented a cold fusion device.
