No, Patrick, I believe YOU are wrong. Radiators and horses (and physics and physiology) are somewhat different.

Radiators cool by radiation and convection, with convection being the major means of cooling by far. Skin cools by radiation, convection and evaporation. Evaporation works best in dry air, but convection works best in higher humidity, because of the ability of the air-borne water vapor to absorb BTUs better than dry air. Water vapor absorbs almost exactly twice the BTUs that dry air absorbs for a given temperature rise. In addition, moist air has a higher heat transfer rate than dry air.

Sorry about getting the thread off-track, Snakebit. Let us know what you find.
