초록

A pair of vertical axis wind turbines are arranged in close proximity to each other so that their vortices interact with each other to provide enhanced aerodynamic efficiency. The wind turbines are spaced as closely as possible while providing for machine and personnel safety. Adjacent wind turbines rotate in opposite directions to enhance the coupled vortex effect. The vertical axis wind turbines may be located underneath a row of horizontal axis turbines in a “bush-tree” configuration to provide greater energy extraction from a parcel of ...

1. A pair of lift-based wind turbines wherein each wind turbine comprises:a shaft that rotates about a vertical axis, anda blade attached to said shaft for rotation therewith wherein said blade is spaced radially outward from said shaft by a predetermined radius,wherein the shafts of said pair of lift-based wind turbines are separated from each other by a distance that is less than three times said radius and greater than two times said radius, and wherein aerodynamic interaction between said wind turbines increases the efficiency thereof. 2. The wind tu...
