Ducted & Shrouded Wind Turbines (DAWTs)
Like Vertical Axis Wind Turbines (VAWTs), shrouded and ducted wind turbines 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. Shrouded turbines are also sometimes called Diffuser-Augmented Wind Turbines (DAWTs).
There is also a collection of archival and recent photographs on the Photos section of this site. There you can find photos of Ducted Wind Turbines (DAWTs).
While ducted or shrouded wind turbines and Vertical Axis Wind Turbines can be of any size, they are listed here because they are outside the mainstream of the commercial wind industry.

They used their ill-gotten gains for personal expenses such as houses and cars, Elser said.
