Cool innovation. Winner of a 2007 Popular Mechanics Breakthrough Award.
[Shawn] 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.Lots of developing world applications. Especially appreciate the ease of repair and maintenance. (as a director of a clean drinking water non-profit once told me: "it's not finding the technology that's a problem, it's fixing it. How do you fix something in the middle of the African bush with no tools, no electricity and no city within two hundred miles?")
