Abstract
The present invention is a system and method for enhancing the generation of power with a windmill. It comprises a horizontal axis rotating propeller with a large hub, mounted on a lift-generating device which also acts as the support structure. By adding a lift-generating device around the support structure, lower rotational speeds for the windmill propeller are possible without the penalty of excessive swirl losses in the wake. The lower design speed reduces parasitic losses and improves the overall power output of the windmill. The present invention also uses a large hub to increase the relative speed of the air over the windmill propeller near the hub, further enhancing power generation.
