Inventor, installation artist, and thoroughly nice chap Tim Hunkin has an article up about his efforts to make a sign for Southwold Pier that was powered by the wind. He gave up and used photovoltaics, but the journey is fascinating, and a useful lesson in the problems and limitations of wind power.

(via Make, slightly annoyingly since I was looking at Tim’s site not so long ago. Don’t miss the Quantum Tunneling Telescope, either)
