The focus of DWT’s product development is to reduce the cost per annual kWh of wind energy. And that’s without incentives, since those won’t last forever. Our target is 1/2 the cost per unit energy ($/kWh) of products on the market today. In other words, we would produce twice the energy for the same cost. Energy is what’s important, not the power rating of a turbine at 11 m/s. We are currently focusing on developing our Gen 1 unit, a commercial prototype in the ~7000 kWh/year range, based on an average Rayleigh distribution wind speed of 5 m/s.
|Configuration:||3 or 5 bladed downwind|
|Cut-In wind speed:||< 3 m/s|
|Cut-Out wind speed:||TBD|
|Rotor Diameter||3.0 m (9.8 ft.)|
|Duct Diameter||3.7 m (12.0 ft.)|
|Rated Power||3500 W|
|AEO (5 m/s)||6700 kWh|

The Gen 1 test unit can be seen live in operation at Clarkson University. It was officially put into operation during the April 2019 ribbon cutting ceremony and is mounted on the TAC Building.
