http://www.humdingerwind.com/Until recently, the only commercially viable wind harvesting device was the turbine. Humdinger’s Windbelt™ is the first non-incremental innovation beyond this century-old approach.
Instead of using conventional geared, rotating airfoils to pull energy from the wind, the Windbelt™ relies on an aerodynamic phenomenon known as aeroelastic flutter (‘flutter’). While the phenomenon is a well-known destructive force (e.g., a cause of bridge failure), researchers at Humdinger have discovered that it can also be a useful and powerful mechanism for catching the wind at scales and costs beyond the reach of turbines.
At its heart, The Windbelt™ uses a tensioned membrane undergoing a flutter oscillation to pull energy from the wind.
From Wikipedia, the free encyclopedia -

The Windbelt is a device for converting wind power to electricity. A windbelt is essentially an aeolian harp except that it exploits the motion of the string produced by the aeroelastic flutter effect to move a magnet closer and farther from one or more electromagnetic coil and thus induce current in the wires that make up the coil.
Prototypes of the device are claimed to be 10 - 30 times more efficient than wind microturbines. One prototype has powered two LEDs, a radio, and a clock (separately) using wind generated from a household fan. The cost of the materials was well under US$10.
An improvement on the prototype increased efficiency hundredfold bringing the cost down to around $2 a watt. There are three sizes in development - a 'micro' version that could be used to charge small gadgets. This could be put into production in around six months. A 1 meter version that could be used to charge cellphones or run LED lights This could go into production within 18 to 24 months. An experimental 10-meter model that has an unknown production date.
The Windbelt's inventor, Shawn Frayne, was a winner of the 2007 Breakthrough Award from the publishers of the magazine, Popular Mechanics. He is improving the Windbelt's design to make it more affordable.windcell March 2010
