The invention describes a Wind Collector, referred to as the Drag Rotor, based on the air resistance, called the Drag, which is engendered by the foil surface of its body. In the wind industry, Rotors function as transformers of wind power into rotational motion, where stabilized velocity is primarily significant. In the Wind-Hydro Generator Process, referred to as the Process, and developed in a separate patent application, this rotation of the Drag Rotors transmits a torque, which turns a shaft, which actuates a Hydraulic Generator (pump, or motor or turbine acting like a pump), and converts the wind energy into kinetic force of a water flow (See Figure 6d). Drag Rotors preferably are coupled (see Figure 1) to enhance the wind power collection by using a common central deflector which enables minimizing any potential "negative drag". However 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 conform to local regulations - see Figure la). Drag Rotors use sails shaped like an arc of a cylinder or using a spiral spine, with an off-centered axis of the central rotor versus the stator. One side of the sail is guided alongside the external circle (the Stator) while the other side swivels while turning with the central rotor wheel. This "off-centered" motion enables each sail to turn separately and differently from the others according to its position with the rotor's shaft. The sails being made of cloth enables varying the dimensions of the overall foil surface of the Drag Rotor simply by modifying the height or the width of the sails, like on sail boats, so that they offer only resistance to the wind as the user needs, (e.g. in storm conditions where it may be dropped entirely). Unlike conventional wind turbines, Drag Rotors may be considered as variable displacement devices.
