The Sauer Energy Vertical Axis Wind Turbine (VAWT) is highly efficient because of the maximum drag produced by the power generating blades as they are moved by the wind. The equal blade of the turbine produces less drag. Thus, efficiency increases with the degree of differential between high drag and low drag.
The concave high drag side of the wind transfers kinetic energy to the rotor shaft. The rotor shaft of the VAWT will be directly connected to a generator to convert over to usable electricity. The convex blade will produce less aerodynamic drag.
The Sauer Energy VAWT drag is incrementally reduced because its swept area and the drag force may be controlled. The turbine torque is gained by increased size of blades and distance in mass, rather than vertical height. The force produced by the volume of the wind is directly applied to the rotational axis of the turbine, thereby extracting maximum power at lower wind speeds.
Larger wind-swept area will result in slower rotational speed, which will create a greater torque and more power flow. To increase the power flow of our VAWT, the size of the turbine blades must be increased to resist more of the wind’s mass. Thus, scalable models can adapt to the various needs.
Sauer Energy considers drag to be a much more powerful force than lift in harnessing and capturing kinetic energy. More mass equals kinetic energy.
