This thread is more fun than the one that just got locked in Aerodynamics.
I called my son to tell him about the Aptera, and the skin radiator system. It uses a heat pump, apparently.
The last car I recall having skin radiators was the Stutz Blackhawk Special, but it turns out that that was an intercooler and the engine cooling was by ice.

It does have Aptera-like front fenders.
