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.

Stewart Russell captured these photos of a Mariah Windspire installed at the College School in St. Louis. Stewart is an experienced wind hand and noted that the Windspire, which is an unguyed, cantilevered VAWT, was swaying in the wind. A flyer was posted on the turbine saying that this swaying was normal.

This is a classic example of how not to install wind turbines to best advantage. The best that can be said about this installation is that at least they were not mounted on top of the building.
