An electric power generation system includes a wind turbine, a conductor rotating as the wind turbine rotates, a heat transfer medium vessel, a magnetic field generator, a heat accumulator, and an electric power generation unit. The magnetic field generator is operated to generate a magnetic field and therein the conductor is rotated and thus heated through induction, and the conductor's heat is transmitted to the water in the heat transfer medium vessel to generate steam which is in turn supplied to a steam turbine and thus drives an electric power generator to generate electric power.

Systems store energy mechanically at a first time and extract the energy at a later time. When excess electricity from renewable sources or during off-peak periods is available, a pump directs a working liquid (L) to pressurize a gas (G) that is confined within a pressure vessel. When electricity from renewable sources is not available or during periods of peak demand or pricing, the pressurized gas (G) directs the working liquid (L) through a hydropower turbine. The turbine drives a generator through a mechanical coupling to provide electricity for powering a load. In addition, the system can leverage (take) any waste heat as the input to boost the efficiency of the system. The described systems function at ground level and are modular and scalable in capacity.

The energy-storing and power-generating system comprises an energy-storing system and a power-generating system. The energy-storing system comprises a high pressure gas generator, a water storage apparatus and a water turbine. The high pressure gas generator comprises at least one sealed high pressure gas tank (2) and an air compressor (1) cooperating therewith. The water storage apparatus comprises at least one sealed water tank (3). The air compressor is in communicated with the high pressure gas tank via a gas inlet pipe (4), while the high pressure gas tank is in communication with the water tank via a gas outlet pipe (5). The water tank is connected to a water inlet of the water turbine (10) via a water outlet pipe. Blades (102) of the water turbine are connected to the power generator via main gears.

Energy harvesting system, for harvesting energy from renewable resources, including an array of wind turbines disposed along a towering construction, and plurality of laterally outlying ledges branching outwardly in vertically spaced-apart respective levels, alternately lined-up along the towering construction between the wind turbines. Each of ledges includes an upper ledge surface and/or a lower ledge surface, slanted at a slope for deflecting ingoing wind and/or diffusing outgoing wind toward and away from the adjacent wind turbine, respectively. A photovoltaic (PV) solar panel layout is disposed on upper ledge surface, and includes at least one PV solar panel for absorbing and converting solar energy into electricity. The system may include one or more energy storage modules, usually operational for being lifted along towering construction. The towering construction may include wind and solar sensors and may be rotatable, so as to adjust horizontal orientation of towering construction for optimal energy harvesting.

A floating power-generation group comprises a floating hub such as a spar buoy that is anchored to subsea foundations by anchor lines. Floating power producer units such as wind turbines are connected electrically and mechanically to the hub. The power producer units are each moored by mooring lines. At least one mooring line extends inwardly toward the hub to effect mechanical connection to the hub and at least one other mooring line extends outwardly toward a subsea foundation. The groups are combined as a set whose hubs are connected electrically to each other via subsea energy storage units. Anchor lines of different groups can share subsea foundations. The storage units comprise pumping machinery to expel water from an elongate storage volume and generating machinery to generate electricity from a flow of water entering the storage volume. The pumping machinery can be in deeper water than the generating machinery.

A system (1) for harvesting wind energy from passing vehicles (2), storing the energy and using the energy to generate electricity. The thrust of wind from passing vehicles (2) is captured by one or more single separate sail, board or blade (3), to creating reciprocating motion. This is used for actuating one or more pumps (4) so it pumps a fluid upwards bringing the fluid into an upper reservoir (6) generating and storing potential energy. Immediately or at a later time, the fluid can be allowed to flow back to the lower reservoir (5) and the flow can be to drive a turbine or turbines (7) or to generate electrical power. Wind generated by passing cars is stored as potential energy and used, immediately or later, to generate electrical power.
