Vertical Axis Wind Turbines
Vertical Axis Wind Turbines (VAWTs) can be both small and large. However, they are not the mainstay of the wind industry and for that reason they are assigned a category under Small Wind Turbines on this site.
There is also an extensive collection of archival and recent photographs of VAWTs and various forms of Darrieus turbines on the Photos section of this site. There you can find photos of Vertical Axis Wind Turbines.

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.

Darrieus Wind Turbine Technology Assessment Study (1992)
By
Lawrence Schienbein
One of the conclusions then is no doubt true today: “There is no well established relationship between Darrieus wind turbine prototype costs and volume production costs because only one company, FloWind Corporation, has manufactured and installed more than 100 Darrieus turbines of any model in one year.”
