I was just disputing the idea that the concept of keeping cold fusion going with external heat is a simple extrapolation from other sources of heat that require external heat to keep them going.

That's what he claims to give an excuse for attaching a source of power. But the problem is, if it's heat, how does it know that it's external? Heat just produces a temperature in the fuel. If the heat from the fuel can maintain that temperature, how can adding heat stabilize it? As I said, this is conceivable if the external heat is more concentrated (at a higher temperature), but in the hot cat, it must be more diffuse, and at a lower temperature. > That's how it works.
