Donut-Shaped Wind Energizer Improves Wind Turbine Efficiency


Better air dynamics

A company called Leviathan Energy has come up with a clever way to improve the efficiency of wind turbines, without making any modifications to the turbines or propellers themselves. Using aerodynamic modeling, Leviathan designed a special plastic and metal skirt structure that wraps around the base of the wind turbine and directs the flow of the air to the critical areas of the blades. The system is guaranteed to increase the power output of a wind turbine by at least 15-30%, and at lower wind speeds (0-6 meters per second) the gains can be as high as 150%.
