摘要： A buoyant hydrodynamic pump is disclosed that can float on a surface of a body of water over which waves tend to pass. The pump incorporates an open-bottomed tube with a constriction. The tube partially encloses a substantial volume of water with which the tube's constriction interacts, creating and/or amplifying oscillations therein in response to wave action. Wave-driven oscillations result in periodic upward ejections of portions of the water inside the tube that can be collected in a reservoir that is at least partially positioned above the mean water level of the body of water, or pressurized by compressed air or gas, or both. Water within such a reservoir may return to the body of water via a turbine, thereby generating electrical power (making the device a wave engine), or else the device's pumping action can be used for other purposes such as water circulation, propulsion, or cloud seeding.

摘要： The invention relates to a system for storing and recovering energy, comprising at least two liquid containers for storing a liquid, the two liquid containers being preferably located at substantially the same level and/or preferably having a substantially identical volume, and a turbine unit for power generation, which connects the two liquid containers to one another and is designed in such a way that the liquid can flow from the one liquid container through the turbine and into the other liquid container and thereby drives the turbine, and a working gas provision unit for providing a working gas, in particular air, having a substantially constant working gas pressure, the working gas provision unit being connected to the two liquid containers and designed in such a way that the working gas having said constant working pressure conveys the liquid from the one liquid container, via the turbine unit and into the other liquid container.

摘要： A system for converting fluid flow into electricity. The system has an arm assembly with four floats that rotate around a center float. The floats on the arm assembly are all provided with impellers that turn one half revolution for every one revolution of the arm assembly. This slow rotation maintains the impellers at the optimal angle to convert the flow of the water current into rotational motion of the arm assembly, regardless of the orientation of the arm assembly. The arm assembly is coupled to an electric generator provided on the center float that converts torque generated by the arm assembly into electric power that may either be stored on an on-board battery or transmitted by wire for use elsewhere.

摘要： The present invention relates to a power generation apparatus, and more particularly to a power generation apparatus that generates power by dropping collected water. A power generation apparatus according to an embodiment of the present invention includes: a chamber having an accommodation space for accommodating water, and configured to accommodate water introduced through an intake pipe disposed on the bottom surface thereof; a pressure pump configured to discharge the air of the accommodation space out of the chamber through a discharge pipe provided on the ceiling surface of the chamber by generating pressure; a spray unit provided on the side surface of the chamber, and configured to spray water, introduced by the pressure pump and accommodated in the accommodation space, out of the chamber; and a power generation unit configured to generate power using the pressure of water sprayed by the spray unit.

摘要： An energy conversion apparatus 1 comprises: a liquid tank 11 in which a liquid 10 is stored; a plurality of gas-receiving parts 12 that are provided in the vertical direction inside the liquid tank 11 and are free to rotate or move vertically; a nozzle 13 that, inside the liquid tank 11, ejects compressed gas from below the lowest positioned gas-receiving part 12; a gas cylinder 14 that stores compressed gas serving as a primary energy source and feeds the compressed gas to the nozzle 13; an output means 3 that outputs kinetic energy of rotation or vertical movement as secondary energy to the exterior of the liquid tank 11, the kinetic energy being generated in the gas-receiving parts 12 by a buoyant force that the gas-receiving parts 12 generate as a result of receiving the compressed gas ejected from the nozzle 13; and a recovery device 4 that returns the gas from the liquid tank 11 to the gas cylinder 14.

摘要： Disclose herein is a hydropower system for deployment in a natural body of water that has a at least one first cylindrical tube member disposed through a concrete block assembly and coupled to a turbine tunnel assembly designed to receive water from a natural body of water via gravitational forces acting on the water. At least one water intake with a vortex breaker is operationally coupled to the cylindrical tube member. At least one turbine generator assembly has a plurality of upwardly angled but non-vertical blade members extending therefrom around a central axis adapted to rotate an electric generator. At least one second cylindrical tube member is coupled to at least one injection hole member to at least one or more of a fault line, an underground water system, and a river system that impart energy to move the water back into the natural water cycle.

摘要： A system for generating electricity includes a bar and a source of a pressurized fluid. A three-way connection piece has an inlet opening connected to the source through an inlet solenoid valve and a discharge opening connected to a discharge solenoid valve. A connection line connects the three-way connection piece to a working cylinder. A shaft of the working cylinder strikes against the bar causing an oscillating motion. A first and a second rod convert the oscillating motion into a back-and-forth translational motion which a drive means converts into a cyclical drive motion. An apparatus for generating electrical energy is driven by the cyclical drive motion. During operation, the inlet solenoid valve and the discharge solenoid valve are continuously switched from a first working position to a second working position, and vice versa, at a frequency which is identical to the natural frequency of the bar.
