A method for storage of excess energy which would otherwise be lost, the regulation of angular velocity, and prevention of excessive velocities is disclosed. The device consists of a bowl shaped container, divided into sections by radially oriented vertical walls, which holds a fluid (any appropriate liquid or set of small solid particles), and spins on its vertically oriented axis at various angular velocities. The floor of the device is formed in successive shapes of bowls and shelves, which allows for a kind of “gearing”. The invention allows more and more energy to be input into the device while the angular velocity is regulated within a particular range. A typical embodiment of the invention would include its attachment by a shaft at the axis to a vertical axis wind turbine.

MECHANICAL ENGINE FOR THE GENERATION OF ENERGY THROUGH WATER MOVEMENT, refers to a mechanical motor (1) to (41), with their auxiliary sets, with the objective of generating mechanical and electrical energy, or both, being plants electric lines with this system can be built on the banks or inside the sea, river or islands, where the cost benefit of the energy by the conventional way, does not become compensating, or practically inaccessible places, but that have waves, tides, or level differentials in waters. As these sources of energy, in water there are in abundance on the planet, possible future plants of this system, may be more spread out, and in greater quantity, thus reducing the number of posts, towers, compensation equipment, components, and transmission wires. In case of use in water navigation, this engine can be used to replace, totally or partially, conventional fuels and engines, for mechanical handling, and the generation of electric energy on board.

A system of recycling power from flowing fluids, uses a fluid pump, e.g., a water pump or an air pump, driven from a power source to create a flow. A fluid movement recycling device, is located in the path of the fluid flow, such that the fluid flowing causes the fluid movement recycling device to rotate. A DC motor, receives the rotation from the fluid movement rotating device, and produces an output of DC power, which charges a battery that itself is used to drive the fluid pump.

A method for harvesting energy from a train passing over a railroad rail. The method including transferring a deflection of the rail from the train to a mechanical energy storage device; storing mechanical energy provided by the transfer mechanism until a predetermined amount of mechanical energy is stored; transferring the stored mechanical energy to a generator upon the stored mechanical energy reaching the predetermined amount; and converting the transferred mechanical energy to electrical energy.

A vertical axis wind energy power turbine having a hollow shaft on which are attached, rotating and fixed components with outer-surface shapes, fixed vanes, and integral heating to concentrate without confining airflow, an overspin-limiting power-enhancing self-engaging flywheel, and, conversion systems for both, pumped air that may be transferred through hollow mountings to do other work, and, for electricity generation.

A rotor for a vertical axis wind turbine generator features a flywheel having first and second faces located opposite one another across a thickness of the flywheel, and a circumferential perimeter edge joining the first and second faces together around the central axis at a perimeter of the flywheel. A series of cavities are spaced radially inward from the circumferential perimeter edge and open into the flywheel from the first face on a path disposed circumferentially about the central axis. A series of permanent magnets carried in the cavities have the opposing poles of adjacent magnets facing in the same axial direction. The recessed magnet configuration avoids the separate magnet-retention means required for flush-mount configurations, and increases the performance of the generator.

This invention relates to a wave energy recovery apparatus with a power-take-off arrangement comprising at least a base, a reciprocating panel, two power-take-off (PTO) units with one or more generators to convert kinetic energy of waves or tidal currents to electricity, at least two gear transmissions operatively connected between the panel and the generators and at least two one-way clutch mechanisms to control the directions of rotation of the generators. The panel is arranged to rotate a half of the generators when rotating into one direction and another half of the generators when rotating into the opposite direction.

A traction mat system and a method of manufacturing comprising a mat having a grip layer adhered to or mate integral to the surface of the mat. The grip layer can be a textured material foil sheet combined to a top surface and/or a bottom surface of the mat system. The texture of the grip layer is retained when the mat is contoured with a raised pattern to give the entire surface of the mat a texture to improve traction and grip. A method of manufacturing comprises a traction mat system wherein the traction mat can comprise of manufacturing step for placing a grip layer on the mat surfaces, for placing the foil sheet and/or aggregate on the mat. Each operation can be performed for both surfaces simultaneously or can be its own operation such as one surface at a time, or both surfaces at once.

The present invention is designed and calculated to use different wind regimes, namely, laminar, turbulent and hurricane-wind regimes, to exploit at the industrial level the enormous wind potential in the different regions of the planet. The result is a wind-based electrical power generation system that couples a mechanical system to an electrical system.

A wave power generation unit suitable for large-scale application and a system thereof are disclosed. The wave power generation unit includes at least two types of water platforms that dynamically differ from each other under the effect of waves: stationary floating platform and movable floating platform. The two types of floating platforms are paired to form a functional unit, and the difference between the two floating platforms caused by waves causes interactions between the two floating platforms. The movable floating platform converts wave energy into mechanical energy, and the stationary floating platform converts machinery energy into electrical energy. The dynamic features of the floating platform are adjusted by a sink and float control device or a peripheral lifting device, and the adjustment effect is enhanced by a large-mass flywheel. Multiple wave power generation units form a wave power generation system.
