After losing power in southeast Michigan for 3 days, a couple of weeks ago, I began wondering about low-power cooling. Something like a couple of solar panels, a battery of some kind, then a fan for an evaporator "swamp cooler" or something similar. I'd like to be able to cool a single room occupied by 2 adult humans and a couple of 75lb dogs.

How much power do those mini refrigeration compressors draw?
