how much cooler would the air be if a hook up a thermoelectric to a heatsink and a fan ?
Like this: thermoelectric = 0 Heat Sink = E Fan = S
0--E--S
would the air be any cooler or would it be a total waste ?
It can be done but you have to have a heatsink and fan on the HOT side too.
Thermoelectric use a LOT of power.
A small window air conditioner is prolly way more efficient.
Both have a hot side and a cool side.
YMMV
