Lets try to get you back on track. When considering aeration for my pond I researched windmill aeration systems extensively. The conclusion that I came to was that if you had power withing 1,000 feet or so you are better off using a conventional plug in aeration system. The main problem with windmill aeration is that since you are at the mercy of the wind you are not able to exercise any where near as much control over the aeration system as you can with a conventional (plug in) aeration system.

You could put a plug in air pump near your power source and run the air tubing to the pond. The advantage this would have is that by using a timer you can control when it runs and how long it runs. You would probably have to dig a trench to bury the air tubing though.
