The Humdinger Windbelt.

The Humdinger Windbelt is a device that utilizes the property of things to flutter in the wind (things like laundry lines and bridges) to generate power. It's a type of wind generator that doesn't use turbines. (I think I remember reading in a Bucky Fuller book his assertion that we need to improve efficiency by moving away from rotating mechanisms.) The Humdinger website claims at least an order of magnitude improvement in efficiency over current micro-turbines. I think it's super cool and eagerly await independent confirmation by way of the soon-to-be-released developer kits.
