On a day when the nation is holding its breath to see if BP's cap will stay intact, it's worth thinking about small scale power power solutions. The sight of solar panels on rooftops is a familiar one, but I didn't realize until recently that proponents of wind energy envision a similar approach. For $15,000 or so you can get a 60 foot tower with a wind turbine on it and get your house powered. For half a mil, you can apparently power a small waste treatment plant.
Do I need to point out they don't spew millions of gallons of filth into any nearby bodies of water?
