Former Soviet Weapon Designers Take On Wind Power

WorldChanging has a short item about a home-use electricity-generating windsail designed by engineers at the Lawrence Berkeley National Laboratory in the US and the Makeyev State Rocket Center in Russia. Unlike a horizontal-axis wind turbine, this one is supposed to be quieter and less hazardous to birds. As you can see from the table below, you need a pretty brisk wind to keep even one light bulb burning.
