摘要： A free stream fluid kinetic energy conversion device combines a large diameter freewheeling primary rotor with small diameter secondary power takeoff rotors placed within the lift induced blade tip vortices of the primary rotor. This enables use of high rotational speed generating units and avoids diseconomy of scale in gearbox expense. The device partially recovers otherwise lost blade tip vortex energy. The freewheeling primary rotor transmits no reaction torque to the support structure. Resilient buoyant tether deployment accommodates transient eddy induced structural loads.

摘要： The invention relates to an on-board assembly for producing and storing electricity, including at least one hydrogenerator having an output line connected to at least one electrical battery having predetermined electrical load parameters. The hydrogenerator includes a load-bearing structure onto which a generator and an impeller, secured to a shaft for driving a rotor of the generator, are mounted. Said assembly is characterized in that the generator is an excitation generator, and the hydrogenerator includes a rectifier circuit, connecting the generator to the output line, and at least one circuit for exciting the generator. The excitation circuit is connected to an excitation current regulator controlled by a control unit set up so that the generator provides a load current consistent with the electrical load parameters on the basis of a resisting torque of the generator, said torque being predetermined so as to limit drag of the impeller.

摘要： A dual rotor arrangement 100 for a wind or water turbine has a planetary gearbox with two inputs and an output. One rotor 1 is connected to one of the inputs 3 and the other rotor 8 is connected to the other input 6. A generator is connected to the high speed shaft 11. The rotational speed of the output is determined by the relative rotational speeds of the rotors which means that the generator produces electricity of a desired frequency. The arrangement enables electricity of constant frequency to be generated under conditions where the wind or water speed is variable.

摘要： A spiral turbine blade having at least one concave compartment that is rotatable by a moving fluid for the generation of electricity is provided. A spiral turbine blade is aligned so that the axis of rotation is generally parallel to the mean direction of a moving fluid. Attached to the intake-facing side of the at least one spiral turbine blade are concave compartments comprised of an intake void, interior space, and exit void. The concave compartments are oriented to capture an additional range of velocity imaginary vectors; specifically those aligned via vortex inducing elements, such as spiral depressions on a conical intake shroud, thereby augmenting the torque induced the spiral turbine blade, and thus improving the conversion efficiency and electrical energy output.

摘要： The present invention describes a floating yawing spar buoy current/tidal turbine. The spar includes a spreader above the rotor(s) with the spreader tips connected to fore and aft cable yokes that transition to opposing mooring lines connected to anchors on the seabed. The spreader comprises a yaw motor, which drives gears that engage with a ring gear fixed to the outer perimeter of the spar. Flow direction sensors activate the yaw motor for automatic yaw adjustments of the spar turbine. As tidal direction changes, the entire spar and turbine are yawed to maintain the rotor plane facing the tidal flow. The bottom end of the spar extends to approximately the bottom sweep of the rotor plane and contains a winched vertical mooring line, extending to the seabed and attached to a gravity or suction pile anchor. The turbine drive train can be accessed for servicing from the surface via hatches and ladders within the spar to enter the drive train and generating system vessel. The spar turbine is deployed by towing it in a horizontal position. At the operating site, the yokes are connected to the forward and aft mooring lines and the winch line is connected to the gravity anchor. The winch inside the keel draws the bottom end of the spar down and may be assisted by flooding the keel to reach a vertical position for the spar. The winch is then locked to retain required operating depth, or can actively control operating depth in areas of wide tide level range.

摘要： A submersible power generator with an inner/outer double rotational armatures-type power generation mechanism provided with an outer rotational armature and an inner rotational armature opposing the outer rotational armature and rotatable in a direction opposite of the outer rotational armature, and a pair of propellers disposed coaxially with blades of each of the pairs of propellers twists in opposite directions relative to an extending direction of a central axis of the pair of propellers, and a casing for accommodating and shielding the inner/outer double rotational armatures-type power generation mechanism. The submersible power generator, as installed under water to operate in a current, has a buoyancy F acting thereon that is larger than gravity W acting thereon during operation of the submersible power generator due to gravity acting on the mooring wire, so that F>W+gravity acting on the mooring wire−buoyancy acting on the mooring wire.

摘要： A fluid powered electrical generator system for hydroelectric use or mountable to the side of vertical, man-made structures. The system can be rotatably mounted to the side so that as wind approaches and passes through the generator it will remain oriented to capture wind as it changes direction. The system includes a tubular housing that can also include PV material. A fixed helical vane can be formed onto an inner surface of the tubular housing in a spiral and direct wind more directly onto a fan blade assembly located within the tubular housing before an exhaust. A cone can be mounted at the center and front of a fan blade assembly facing wind passing through the tubular housing. Wind can experience compression between the generator cone and housing resulting in increased pressure and velocity, thereby increasing rotational speed of generator blades as the compressed, spiraled fluid passes through and exits the tubular housing.
