WindTamer (tm) breaks record nearly doubling efficiencies in wind energy turbines

The ducted or shrouded design is technically known as Diffuser Augmented Wind Turbine or DAWT as indicated in the report. According to tests and measurements claimed in its description, the DAWT WindTamer (tm) design almost doubled the efficiency of the conventional open rotor Horizontal Axis Wind Turbine (HAWT) devices. The document indicates additional benefits found with the DAWT turbines tested in comparison with HAWT: quieter, safer and reduced tip speed ratio (TSR). TSR is the ratio of a blade tip speed over wind speed, an indicator of its efficiency. The lower TSR in this case results in less wear and fatigue according to the report.
