dominique_cimafranca writes "Shawn Frayne, a 28-year old inventor, has developed a small wind-powered generator that can be used to power small appliances in developing countries. Unlike the typical propeller design one expects of wind generators, the windbelt uses the oscillation of a membrane that follows the vibration of bridge. The oscillation drives small magnets which generate the electricity. From the article: 'Frayne's device, which he calls a Windbelt, is a taut membrane fitted with a pair of magnets that oscillate between metal coils. Prototypes have generated 40 milliwatts in 10-mph slivers of wind, making his device 10 to 30 times as efficient as the best microturbines. Frayne envisions the Windbelt costing a few dollars and replacing kerosene lamps in Haitian homes.'"
