Abstract

A wind turbine, referred to as a drag rotor is provided that converts wind energy into mechanical energy. Twin drag rotors are described with a common central deflector which minimizes potential negative drag, A drag rotor may be exploited in single structure, using either a vertical or horizontal axis and according to the location where it is to be installed (e.g. on the roof of a building where a horizontal positioning would be more user friendly or to conform to local regulations). Drag rotors use sails shaped like an arc of a cylinder or using a spiral spine, preferably with an off-centered axis of the central rotor versus the stator. One side of the sail is guided by the stator while the other side swivels while turning with hub, This "off-centered" motion allows the surface of the sail to be optimized when facing the wind and minimized when returning against the wind.
