Abstract: Horizontal axis W/T of low wind speeds of propeller type, bearing a main rotor of three blades (1), while in the space between two successive blades (1) and diametrically opposite to the third, an additional 4th blade (2) also of propeller type but of significantly longer length, is interposed. This additional blade (2) is not permanently coupled but selectively engaged in the system of the W/T at low wind speeds, contributing to the startup and enhancing the energy production. The blade (2) bears diametrically opposite a counterweight (15) to balance the forces developed, and rotates in a plane parallel to the main rotor. The coupling of the blade (2) is preferably made at the stand-by state or at low wind speed operation of the W/T, while the uncoupling will be performed during operating state and at the rated power. The blade (2) after uncoupling, gets in vertical position and remains immobilized attached to the tower.

Abstract: A system is provided comprising a tunnel for immersion in a moving mass. Energy from the mass passing through said tunnel converts to rotational force. An energy collector is provided having open and collapsed states, the open state resisting the mass. Bidirectional converter systems convert said rotational force to constant singular direction. A mechanical converter comprises an input shaft turned bidirectionally by said rotational force and two gears driven by the input shaft in opposite rotational directions, the gears separately attached to idler gears causing output gears attached to the idler gears to engage an output shaft in a same rotational direction. A hydraulic converter comprises a hydraulic pump turned bidirectionally by said rotational force. Check valves positioned between the pump and a hydraulic motor enable control of pressure and volume in one direction at the pump.
