Homebrew wind turbine

wind turbine has a great write up on building and flying this 17 foot monster. The turbine features 25 pounds of magnets in the rotors and 16 pounds of copper wire in the stator. It’s a really interesting process going from bearing assembly, to coil mock-up, resin casting the rotors and stator, blade assembly and finally raising the tower. The result is a turbine that can stand up to winds over 60 mph and has been known to produce 3.8kW. It’s a good project and also fun to read because of all of the warnings about not severing your fingers with high powered magnets.
