The five patents (both issued and pending) include surface-compliant plasma actuators that provide high thrust, reducing aerodynamic eddies and decreasing drag to improve electricity extraction in wind turbines. Prior to this invention, plasma actuators had not produced adequate thrust at lower wind speeds. Plasma actuators use electrodes and a dielectric layer to create a charged gas (plasma) plume that creates thrust in a specific direction. The design provides fluid flow entrainment to direct the induced jet away from the wall, increasing the effective thrust while reducing the shear stress on the surface in the proximity of a plasma actuator.
The plasma actuator technology has been tested for months in laboratory conditions. Based on these tests, In 12 mph winds, Plasma Tech has the ability to increase a turbines electricity output to the grid by 108% by increasing the speed of the blades to 25 mph. In zero or near zero mph winds, Plasma Tech can substantially increase a turbines output to the grid by increasing the speed of the blades to 8 mph.
