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 the aeroelastic flutter effect to move a magnet closer and farther from one or more electromagnetic coil(s) and thus inducing current in the wires that make up the coil. A famous example of aeroelasticity is the fall of Galloping Gertie, the original Tacoma Narrows Bridge. The film of the collapse is commonly shown to engineering, architecture, and physics students as a cautionary tale.
