Abstract: The drive system for wind turbine with contra-rotating generator includes various embodiments of belt drive pulley systems for a direct drive contra-rotating wind generator. The generator has a magnetic rotor and an armature mounted on a shaft configured to rotate in the opposite direction from the magnetic rotor. In some embodiments, a belt extends across two pairs of coaxially mounted idler pulleys between a pulley on the magnetic rotor shaft and a pulley on the armature shaft. In other embodiments, the pulleys on the magnetic rotor and armature shafts are double sheave pulleys, and a first belt extends across one or two coaxial pair(s) of idler pulleys between an inner and outer sheave, and a second belt extends across one or two coaxial pair(s) of idler pulleys between an inner and outer sheave. Either the magnetic rotor or the armature shaft or both are coupled to a wind turbine rotor.

Abstract: The combined pump and energy recovery turbine includes at least one fluid flow pressurizing a sliding vane pump and a sliding vane energy recovery turbine that recovers energy from a second fluid flow, such as the brine discharge from an RO seawater desalination system. A cylindrical rotor has two sliding vanes in respective slots, the rotor being concentrically disposed within an oval-shaped enclosure defining two mirror image crescent-shaped chambers, each chamber having inlet and outlet passageways. The first chamber pressurizes the first fluid flow, and the second chamber functions as a second outflow-driven energy recovery turbine, thus enabling the single rotor device to operate as a pressurizing pump on the first fluid flow, and second outflow-driven energy recovery turbine recovering energy from the pressure drop in the second fluid flow.
