Surface radiators for water cooled engines

Surface Area? A standard auto styled radiator has a tremendous serface area
packed into a very small and light package. The air is forced through that
surface area with contact normally on two surfaces as it passes. To obtain the
same surface area on a single sided flat plain would take much more area than
is available on the underside of the cowling. You might be able to get enough
area by using the whole underside of the fuselage but you still don't have the
same type of contact.

Bravo Bob, but no matter how you say it...
there are dreamers and wannabees that just can't let go
no matter what. Evidently, living without the Easter Bunny,
Santa Claus and the Surface Radiator Fairy is unthinkable.
