Abstract
The herein described horizontal and vertical wind energy concentrators are structurally simple and light and are capable of concentrating the wind energy at least six times with very high efficiency. This permits a corresponding reduction in the frontal area of the wind turbine and increases its speed without sacrifice in wind energy harnessed. The wind energy concentrator is a high lift, short aspect ratio wing, which is designed to maximize the induced drag. This induced drag takes the velocity out of the wind but transforms the wind energy into rotational energy present in the shed vortex system. The design is such that most of this rotational energy can be harnessed by a small high speed wind turbine placed in the rolled up wing tip vortex.
