>>>Years ago, when Eddy Merckx was in his prime, he was put on a stationary exercise bike to see how much power he could crank out. There was no air flow, and he blew up at about 1/3 the level the investigators knew he could put out based on his hill-climbing performance during actual races.

>Interestingly, radiative heat transfer from a blackbody varies as the fourth power of the absolute temperature - one of relatively few fourth-power relationships found in nature. Radiative heat transfer rapidly overtakes convective as the temperature climbs; convective heat loss from an incandescent filament is negligible.
Uhhh...far too many multi-syllable words..? Did you say it was hot out?
