Picture: Rooftop Wind Power
December 31st, 2008
Sometimes its good to see a futuristic product. Here’s a rooftop wind turbine . 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. Cost: $10,000 with installation. Let’s wait for the Chinese to copy this and then we will see the price come down!
