Beyond water cooling. (Was Re: Peltier devices for cooling)

[Grant Richter]

I don't think a bar refrigerator was designed to deal
with active heat sources. It's one thing to take
a bunch of beer cans down to 40 F and hold them
there with only leakage from the outside. Or deal
with a continuous 50 (25% of 200) watt heater inside.

Second Law of Thermodynamics. It will take much more
than 50 watts of cooling to get rid of 50 watts of heat.

Conversely you wouldn't want your computer at 40 F so
you could set it at the highest setting. It might be able
to keep up.

(1. You can't win. 2. You can't break even. 3. You can't
get out of the game. The three laws of thermodynamics
as sung by Michael Jackson in The Wiz)
