I, Cringely . The Pulpit . Oh, and We Also Saved the World | PBS

Bob Cringely pulls together a very interesting story about Google and high-flying wind power. I don't know if I can believe his numbers, but they are very compelling: 1/2 cent per kilowatt, and only needing 3,600 sq miles of land to power the entire USA.
