Rooftop Wind Power
Written by Neal Babcock
Homeowners could cut 20% off their electricity bills with a new wind turbine that can be mounted directly on a building. The seven-foot-wide plastic turbine has a ring around its rotors that diffuses noise and limits vibration; the company claims that the turbine is no louder than a whisper. In windy locations, its power output should be about 2,000 kilowatt-hours a year.

I like this design for a couple of reasons: first, the blades are “enclosed”, so you don’t have to worry about them flying off. Second, the whole package is really light, and light is good.
