magnetohydrodynamic propulsion systems? Hey, I've been looking for one of those for my bass boat. :-) Sneek up on 'em.

I am! If I were you, I'd yield to the higher intellect re heat displacement

Here I was, thinking that such blatant name dropping would get IanBruce nowhere.

For the benefit of others here goes a detailed physics explanation from the prefesser....

IanBruce> Yes, Yes --

No, no.

Increased area dissipates more heat. For the case of fluids this is known as the convection rate equation.

Some configurations are better than others. Still if you take any given configuration, and just increase the area the dissipation improves.

Call the "University of Albany" (sic) and ask them.
