Abstract: A wind-hydro power generation system and its power generation method which use both wind power and hydraulic power. Increasing the size of a hydraulic turbine for the hydraulic power generation may result in the decreased rotation power of the hydraulic turbine caused by the resistance of the wind when blades on the hydraulic turbine come out of the water. A blade rotation system on the blades of the hydraulic turbine is provided so that the blades may rotate according to the direction of the wind. As a result, wind resistance is not effected to the rotation of the hydraulic turbine even when the blades on the hydraulic turbine are out of water, but enhances the rotation power of the hydraulic turbine, which enables the use of wind power and hydraulic power at the same time.

Abstract: A wind turbine includes a quartet of pivot shafts in paired parallel relationship and transversely mounted on a central drive shaft, each pivot shaft supporting a pair of wings at opposed ends thereof, the wings offset by 90°. Each pivot shaft rotates cyclically through 90° to move each wing from a wind-engaging orientation (drive position) in which the wing presents a flat surface approximately transverse to the incident wind, to a minimum drag position (glide position). The wings of each pair of pivot shafts open into the drive position at the same time and rotational angle of the turbine. A backstop at the site of each drive position transfers force from each wing to the central drive shaft.

Abstract: The dual rotor turbine configuration efficiently harnesses oceanic wave energy within an oscillating water column system. The up and down movement of the waves creates a bi-directional pneumatic airflow which spins the twin turbine assemblies.

Both rotor sets are locked to a common axle by means of sprag-type freewheeling clutches. This configuration provides for smooth and continuous unidirectional movement of the axial drive line which drives the two generators.
