Vertical Axis Wind Turbines
Vertical Axis Wind Turbines (VAWTs) can be either small or large. Regardless, they are not the mainstay of the wind industry. Very few exist and even fewer than those work. For many years, I kept these pages as subcategory of small wind turbines. However, this arrangement no longer worked well with the current web site design so I’ve put them under the main category of wind turbines even though most serious work on the technology ceased years if not decades ago.
Chapter 6. Vertical-Axis and Darrieus Wind Turbines, of my book Wind Energy for the Rest of Us: A Comprehensive Guide to Wind Power and How to Use It, has an extensive discussion of the technology–all in one place.
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.

UGE Dumps VAWT Business—What Happens Now to Eiffel Tower & Lincoln Field Turbines?
By
Paul Gipe
Controversial developer of “urban” wind projects Urban Green Energy (UGE) is quitting the wind business. Using its in-house designed vertical-axis wind turbine, the New York City-based company installed dozens of the wind turbines on buildings in high-profile locations, including the much-hyped turbines installed inside the Eiffel Tower in Paris.

That this turbine was doomed to fail—and would give small wind another—and unneeded—black eye was obvious from the beginning—for anyone who had the desire to know.
