How much do you think it would cost to run power to your pond. Like Sue said you could run PVC under ground and pump the air from your house. Just have to make sure it's deep enough the condensation doesn't freeze. I have a koenders windmill and it got wrecked in 100mph wind storm. Then I ran power and bought a vertex system and would never think of going back. The windmill was way undersized for my lake of course but the moral of the story is research, research, and more research before you decide. If it were me I would run power to the pond because I am into lighting and bug light feeders and waterfall features. You have alot of options with power there and if you buy a windmill you might be farther away from affording what you really wanted like I did. All depends what you are into.
This kind of goes against my first post but I got lazy. Sorry!!!
