Hi All,

Probably the biggest problem with this idea is that if you drive down the highway, and then get stuck in traffic or a long off-ramp light, and its 100 F outside. There is no air-flow over the radiator, and the only heat loss is radiation. On a regular car the fan just comes on. But how is one going to push air through the flat radiator? The design might have to have little flapper vanes, that stay shut when there is air flowing front to back, but pop up when a fan underneath comes on. Another way to do this would be an electric variable speed coolant pump. To take care of the hot stop problem, the coolant pump could ramp up to full speed.
