摘要： A pumped storage hydroelectric system may include a reservoir system including an upper reservoir system and a lower reservoir system. At least one of the upper reservoir system and the lower reservoir system may include a modular reservoir arrangement. A penstock may be coupled with the upper reservoir system. A pump/turbine may be coupled with the penstock and with the lower reservoir system. The pump/turbine may be configured to receive water flowing from the upper reservoir system to the lower reservoir system for generating electrical power, and to pump water from the lower reservoir system to the upper reservoir system for storing energy.

摘要： A system includes an inlet pipe, a pressure control valve, a flow-through electric generator, and an outlet pipe. The inlet pipe is connected to a carbon dioxide pipeline that flows carbon dioxide. The pressure control valve is installed on the inlet pipe and is configured to reduce a pressure of the carbon dioxide to a specified pressure. The flow-through electric generator includes a turbine wheel, a rotor, and a stator. The turbine wheel is configured to rotate in response to expansion of the carbon dioxide flowing into an inlet of the turbine wheel and out of an outlet of the turbine wheel. The flow-through electric generator is configured to generate electrical power upon rotation of the rotor within the stator. The outlet pipe is configured to receive the carbon dioxide that has expanded through the flow-through electric generator and flow the carbon dioxide to a carbon dioxide pipeline network.

摘要： A manufacturing method for a hydroelectric power generation system includes removing a transaxle including a first motor generator from an end-of-life hybrid electric vehicle, and assembling a hydraulic turbine to a rotary shaft coupled to the first motor generator in the removed transaxle. The rotary shaft to which the hydraulic turbine is assembled may be an engine shaft connected to an engine of the hybrid electric vehicle when the transaxle is mounted on the hybrid electric vehicle.

摘要： The utilization of hydro-generation technology is provisioned inside of water distribution systems within large urban buildings that require water pressure reduction. These micro-hydro-generators reduce the water pressure for tenant use and converts the energy into electricity to be used or sold.

摘要： Disclosed herein is a power generating apparatus for extracting energy from flowing water. The apparatus comprises a buoyancy vessel, and a turbine assembly coupled to the buoyancy vessel which comprises a turbine rotor mounted to a nacelle, and a support structure. The turbine assembly is pivotally moveable between a first position and a second position. When the power generating apparatus is floating on a body of water, in the first position the nacelle is fully submerged below the water surface; and in the second position at least a part of the nacelle projects above the water surface. Movement of the turbine assembly from the first position to the second position is buoyancy assisted, for example by providing the turbine assembly with positive buoyancy or selectively increasing its buoyancy.
Movement of the turbine assembly to the second position may be desirable to reduce the draft or the drag of the power generating apparatus, for example when the power generating apparatus is being relocated, or to prevent damage during storms. In addition, when in the second position it is possible to gain access to the nacelle for maintenance or repair.-

摘要： A system includes a power generator which provides solvent passage from one of the liquids to the other liquid by means of an osmotic membrane provided between liquids taken to a first volume and to a second volume and having different densities and which provides increasing of the pressure of the liquid to which the solvent passage occurs and which provides generation of electricity from the formed pressure. Accordingly, the system includes a first regeneration unit and a second regeneration unit, a retaining chamber, a valve unit, a first density sensor, a second density sensor, and a control unit. The control unit is configured to determine the liquid having high density in accordance with the measurements taken and to determine the operation mode of the valve unit accordingly.

摘要： A waterwheel assembly for a river or similar body of flowing water includes a waterwheel mounted on a support structure, and one or more buoyant members, wherein waterwheel can move up and down, and the buyout members support part of the weight of the waterwheel so that the waterwheel is able to rise and fall with any change to the river level, and the support structure is secured on land by the river or body of water by means of one or more cantilevered beams. The waterwheel has an axle secured between two vertical posts by means of salable bearings that permit the waterwheel to move up and down.

摘要： A hydro-kinetic power generation system is disclosed. The system includes a structure to be positioned in shallow or deep waterways, such as canals and rivers. The structure may be modular, such that the structure may be composed of one or more structural units that are each substantially the same. In various embodiments, each unit includes one or more curved walls for accelerating water through the unit, or through the structure as a whole. In one embodiment, the accelerator walls are curved for optimizing water flow through the structure without generating undue head loss. In certain embodiments, the units may be configured such that the accelerator walls are positioned on opposite sides of the structure, or the accelerator walls may be adjacently positioned. Coupled to the structure are turbines and gear box systems for harnessing energy from the moving water and converting the energy into electric power.
