Project: Build an evaporative cooling box to replace your fridge, an excerpt from The Carbon-Free Home:

The basic premise is to keep food in the shade and covered with, but not touching, a wet cloth. The cloth is kept wet through capillary action by having its edges hang in a pan of water. The pan of water also helps keep away ants and roaches. The breezier the location, the better, as this will increase the evaporation rate and keep the temperature down.
