To All Interested in Aeration. Windmills that create pressurized air that can be delivered to a diffuser on the pond bottom are much better than no aerator to circulate and destratify pond water in ponds that do not have access to electricity. BUT, many windmills do not make much air (1-2CFM), and are not superior low horsepower 1/4 - 1/3 hp rotary vane air compressors which create 4-4.5 cfm. More air obviously creates more bubbles to move more water. But as you point out you need electricity for an electric compressor. When electricity is not an option, now a windmill becomes a valuable and improtant item for keeping the pond's deep water in better and healthier condition.
