Doesn't anybody here use swamp coolers?
Practically free cooling.
Swamp cooler basics: Take a sponge-like foam belt, about 2 feet long and 2
feet wide. Run the belt between two shafts and rotate slowly. Put end of
loop/bottom shaft in a tray of clean water. Blow air through belt.
Evaporating water makes cold air. They work well in areas that are warm and dry.
