    摘要： Embodiments of a hydroelectric system for a low head dam can include a module including a protective housing, a turbine housing retained within the protective housing, the turbine housing including an upper inlet portion at a first end, a substantially tubular portion, and a lower outlet portion at a second end, the upper inlet portion being positioned above the lower outlet portion, a turbine retained at least partially within the turbine housing, the turbine including a plurality of blades coupled with a central shaft, and a fluid pump, the fluid pump being coupled with the central shaft, where the fluid pump is configured to pump a high pressure fluid, a fluid circuit, the fluid circuit including piping, where the high pressure fluid is retained within the piping, and a shoreline generator, the shoreline generator being coupled with the fluid circuit, where the offsite generator is driven by the high pressure fluid that is pumped by the fluid pump in response to the rotation of the turbine.

    摘要： The portable generator is a portable electricity provisioning system that is adapted for use in generating electricity. The portable electricity provisioning system is mounted on a wheeled structure that allows the portable generator to be readily transported to locations where electricity is otherwise not available or is not adequate for the intended use. The portable generator is configured to provide electricity at 120 Vac, 12 Vdc and 5 Vdc and further comprises adequate energy reserves and connections to provide 625 amps at 12 Vdc for use in starting vehicles in maintenance situations. The portable generator comprises an inverter, a jump starting system, a plurality of ports, and a dolly.

    摘要： 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.
