D3 Turbine

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 focused on our Gen 3 unit, a commercial prototype in the ~4000 kWh/year range, based on an average Rayleigh distribution wind speed of 5 m/s.
