ABSTRACT:
A hovering wind turbine (1) whose blades (2) lie on the surface of an imaginary horizontal cylinder and have their pitch angle changing as a function of the rotational angle, allowing them to gather wind energy mainly in the upwind and downwind sectors of the cylindrical path and to use a fraction of the gathered energy to create lift by deflecting air downwards, mainly in the upper and lower sectors of the cylindrical path. The remainder of the gathered wind energy is used to drive a pair of on board electrical power generators (9), and anchoring tethers (13) carry electrical current to a land of offshore site. The turbine (1) is tied to a blimp (11) that is purposely located in its wind shade and keeps it airborne during periods of light or no wind.
