I don't have any experience with them, but there are VAWTs now available commercially. They are quiet and safe. They are also not unattractive.
I watched an episode of "Living with Ed." I know, he's a whack job tree hugger. But in this episode, he had a VAWT and sky lights installed in the house. Like Jack has said, the environmentalists and us, the modern survivalists, want the same things, just for different reasons.
He installed one
like this, except his was a 500 watt unit.
