Super Soda! has been posting a lot of projects, but this is one of my favorites. We covered otherpower’s wind turbine a while ago, but Damon Vander Lind’s turbine features hand-laid fiberglass blades. The core of each blade is hot wire cut out of pink foam by following a wooden airfoil pattern. The fiberglass is laid all at once with five layers at the base and two at the tip. Each layer is slightly offset to handle torque. The entire assembly is mounted to a permanent magnet generator contained inside an alternator case.
