Heidelberg Motor's VAWT Video


In research for his new book, Vaughn Nelson is turning up a number of fascinating videos. One he found is a video of Heidelberg Motor's H-rotor operating in Germany. The VAWT was unusual in that the H-rotor drove tthe large ring generator, seen in the video, directly via a torque tube. Later versions installed at the Kaiser-Wilhelm-Koog test center placed the ring generator on the rotor hub atop a novel tripod tower. Heidelberg installed five turbines at the test site.
