With just about every part made from scratch, and at a total cost of $140.62, this impressive wind generator puts out enough power to meet the electrical needs of a small camper trailer. (Including a laptop computer!)
This ingenious wind turbine uses blades made from a length of black ABS plastic pipe, a stock 30-volt motor for the generator, a 2x4, some sheet aluminum, and some pipe fittings to make a slick-looking, smooth-running piece of machinery. This project page is loaded with nice photos and plenty of details on how the turbine was constructed. There is even complete parts list with some suggestions on the best places to find parts inexpensively.
The latest updates to the page include the author's answers to several questions from readers, and the latest modifications and upgrades. As his web page shows, there's even enough power to run his laptop computer indefinitely as long as the wind keeps blowing.
