Vertical Axis Wind Turbine

A partially completed and currently postponed (at least till warmer weather) vertical axis wind turbine built together with Instructables user BuckFutter. Currently it operates and we have future plans of installing a bike dynamo, and the necessary electrical equipment to charge a 12V universal battery with the ultimate purpose of charging portable electronic devices.

The sails are constructed from canvas drop cloth coated in fiberglass resin and secured to pvc struts at the top and bottom of each sail.
