One other question about aeration vs moving the water via mechanical means.
If a person put in a windmill before the pond filled, in the pond, would the energy from the windmill be more effectively used by turning a mechanical agitation device directly? Or is its best use pumping air and using bubbles to move the water?
Somehow I think the better use of the windmill power would be to mechanically move the water from lower to the upper part of the pond, but I could be wrong.
It seems the deal with pumping air is it is more efficient to move the water by an air pump when buying electricity. But with a windmill we are not buying electricity. Instead we are making an investment in hardware and we really do not care about electric costs. So maybe there is a more effective way to move water with a windmill other than an air pump? Seems to me it is going a long way around to move water with a windmill that was originally designed to pump water.
Ideas?
