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).
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.
The turbine, which whirls on Outer Main Street across from Maxcy Hall, was engineered by Ducted Wind Turbines, founded by Clarkson professor Kenneth Visser.
Elser said the scam was years in the making and a working ducted wind turbine prototype was never built. Instead, Davis and Ridings misrepresented engineers’ opinions about the concept to scam investors and divvied up their money with a third man, Cody Fell of Springdale. They used their ill-gotten gains for personal expenses such as houses and cars, Elser said.
I’ve received a portion of Intertek’s 2016 power performance test of Ogin’s Model 2.2 150-kW ducted wind turbine “over the transom” as we say. The much hyped and controversial device delivered its rated power in the test.
The US Department of Energy (DOE) announced 19 November 2019 that the Distributed Wind Competitiveness Improvement Project had awarded a grant to Ducted Turbines of Potsdam, New York for nearly $200,000.
