A combined sea wave photovoltaic power plant for generating electricity from sea waves and from the sun that includes a pontoon, a jib, a hydro-cylinder, a photovoltaic panel, and conversion system that is designed to be connected to the electricity grid. The photovoltaic panel is assembled on a top of the pontoon and is connected to the conversion systems.

A renewable energy generation method includes: a first production process in which electric power is produced by converting wave energy into electrical energy using a plurality of power generators having the shape of a roly-poly-like capsule that floats in a sea; a storage process in which the electrical energy produced in the first production process is stored in a first hub connected to the power generators; and a transportation process in which the electrical energy stored in the first hub is transported to a predetermined place by use of a transportation.

A wave energy converter (1) has: a buoyant structure (2) which, in use, floats on water; a generator (18); a generator drive mechanism (38) on board the buoyant structure (2), the generator drive mechanism (38) having an rotational input drive shaft (20) and a rotational output drive shaft (36); a drive member (22) operably connected to the input drive shaft (20), the drive member (22) being moveable back and forth between a first position and a second position; a biasing arrangement (23, 26) for example a buoyant block acting on the drive member; and, a submerged element 4, 4′ which, in use, moves below the surface of the water out of phase with the buoyant structure (2), the drive member (22) being attached by a tether (28) to the submerged element (4). In use, when the buoyant structure (2) encounters a wave crest, the spacing between the buoyant structure (2) and the submerged element (4, 4′) increases and the drive member (22) is pulled towards the second position by the tether (28), and, when the buoyant structure (2) encounters a wave trough, the spacing between the buoyant structure (2) and the submerged element (4, 4′) decreases and the drive member (22) is urged towards the first position by the biasing arrangement (23, 26). The back and forth movement of the drive member (22) between the first and second positions causes the input drive shaft (20) to rotate and, thereby, causes the output drive shaft (36) to rotate. The submerged element (4, 4′) is preferably a heave plate. The invention also comprises a heave plate for a submerged, partly submerged or floating structure.

A Mobile Autonomous Solar-Wind Electrical Station (MASWES) comprises an offshore container (2), which equipped with a reinforced case (18); a reinforced grillage (19) provided by at least two beams laid along, and plurality beams laid across the container (2); at least two reinforced internal columns (42) arranged in opposite corners of the container (2) and between the grillage (19) and the middle part of the reinforced case (18); a plurality of light reflecting mats (21); a plurality of movable screw-piles (22), which in the transport position are stored in the plurality of cylindrical channels (38); at least two monolithic towers or telescopic masts (52) of powerful horizontal-axis wind turbines (23) providing at least 10 kW power each with blades and wind vanes taken off in the transport position. The reinforced internal columns (42) are the bases for the monolithic towers or the telescopic masts (52) and equipped with a hydraulic mechanism or an electric actuator (54) and an erection tool for installation of mentioned monolithic towers or telescopic masts (52). The container (2) comprises gondolas, which in the transport position are arranged horizontally in opposite ends of the container (2); a plurality of photovoltaic double-sided panels (24); a plurality of multifold frameworks for photovoltaic panel arrays (25) with at least 30 kW power total and at least one charging point (28) stored inside the container and at least one rechargeable battery (31).

The electrical power generation system using renewable energy is particularly adapted to provide electrical power to an independent or remotely situated electrical device such as a street light, emergency call box, or illuminated road sign. The system includes a pivotally mounted venturi with vanes assuring that the venturi is oriented into the prevailing wind. A vertical axis wind turbine is installed in the venturi throat, and drives a shaft extending through the column upon which the venturi is installed to a generator at the base of the column. The venturi and vanes may include photovoltaic cells thereon for further electrical power. The venturi may be heated from a geothermal source, and may include a variable diameter internal wall to adjust the cross-sectional area of the throat of the venturi. The use of functionally graded materials and other phase change materials may also improve the performance of the device.

The present disclosure first uses a pumping device to retrieve water using an internal power source from a water source. Then, in accordance with a wind parameter and a solar parameter, wind-powered and solar-powered pumping devices are selectively engaged to replace the pumping device. The water is stored in the water storage device in a higher place. As the water runs through an inlet pipe, it is pressurized to drive a first hydraulic generation device. Then the water's potential energy is used to drive a second hydraulic generation device as the water is recycled to the water source. The produced electricity is delivered to the pumping device and, if any remaining, then to a light device for illumination.
