This is an older video I found in my phone. Essentially I took apart a small aquarium pump, realized it was magnetic drive and that it would make power if spun, then hot glued a fan to it. The framework is scrap pvc with a plastic bottle tail and the diode stack was removed from a scrap gasoline generator. It lasted about 1/2 an hour until the wind tore it apart.
