 Here is a far out question.

 There have been a few attempts to cool an engine by dissipating the heat to
 the skin of the aircraft.  Could this be a viable alternative to a
 drag-inducing radiator?

I think the cracking and leaks stopped them.

Porsche will try anything: annular brakes, alumnium tube-frames, electron beam
welding cranks together...

The skin-to-PocoFoam part is what I'm curious about: alumnium (corrosion),
brass/copper (heavy), carbon ( the fibers run normal to the PocoFoam
plus it needs
350s cure epoxy which means a tool and oven), ? I emailed them about this, tho.
