Disclosed is an apparatus that floats at the surface of a body of water over which waves pass. Passing waves cause a nominally vertical axis of the apparatus to tilt away from an axis normal to the resting surface of the body of water. Tilting of sufficient magnitude and duration allows a fluid to flow through a channel that in an un-tilted apparatus would require the gravitational potential energy of the fluid to increase (i.e., to flow uphill), but, because of the tilt allows the fluid to flow through the channel in a downhill direction. Flowing water is trapped at a plurality of levels which in an un-tilted apparatus are higher than the respective levels from which the fluid has flowed. A subsequent tilt of the apparatus in a sufficiently different direction, and of a sufficient magnitude and duration, causes the trapped water to flow to new, yet higher levels. Successive wave-driven tilts of the apparatus incrementally raise water to a height and/or head from which a portion of its gravitational potential energy can be released, and/or converted to electrical power, by causing the water to return to a lower level by flowing through a water turbine thereby energizing an operationally connected generator, or through some other apparatus that performs a useful function when supplied with a flow of high-pressure water.

A wind power generator includes a vertical axis type wind power generation mechanism and a support mechanism. The wind power generation mechanism includes a wind collector, a windmill with a plurality of blades, a windmill rotation shaft, and a generator. The wind collector is formed to surround an outer circumference of the blades. The generator is directly connected to the windmill rotation shaft.

The wind power generator installed in a stationary state enables to generate power, or the wind power generator fixedly installed on a moving body enables to generate power. The A rear end portion of a horizontal axis type wind power generation mechanism is detachably connected to a lower end portion of the vertical axis type wind power generation mechanism.

A hybrid power generation system according to an embodiment of the present invention includes: a blade provided on a vertical shaft to reduce noise and vibration during rotation; a wind collecting duct increasing speed of wind and rotating the blade at a high speed to improve efficiency of wind energy; a wind collecting room provided in the blade to increase a rotational force and efficiency of wind energy; a photovoltaic module concentration device driving a wind inducing rotation motor provided in the wind collecting duct to rotate a wind inducing rotation blade with solar energy to increase wind and forcibly discharge the wind into a blade wind collecting room of a turbine module to increase an amount of power generation even when wind does not blow, and technologies based on Internet of Things (IoT) and Artificial Intelligence (AI), such as a camera, a fire detection sensor, a drone, and the like that can reduce a risk of breakdown of the system and operate efficiently.

This invention describes the electrical power generation in a sustainable way, by means of a device, which is installed in the downpipes of rainwater collected by the building roofs, capable of transforming the potential energy present in said rainwater runoff into electrical power, where the generated energy is stored in batteries or fed into the utility network.

A hydrodynamic power generation assembly and method of use therefor for generating electrical power from the combination of kinetic energy, hydrostatic energy, and turbulent energy of water. The power generation assembly comprises a water accelerator assembly comprising a support structure which is at least partially buoyant and a baffle panel member (or an array of baffle panel members) having an opening, inter-panel spacing, or flow passageway around the baffle panel(s). A hydropower converter is supported from, by, or on the support structure and is operatively coupled to a generator. The hydropower converter is positioned behind baffle assembly. Water flowing through or around the baffle assembly has an increased velocity relative the ambient current and therefore is capable of generating more power relative to the ambient water where power generation assembly is deployed. Particular types of hydropower converters suitable for use with the invention are turbines and water wheels.

A fluid-driven power generation unit, may include two sets of airfoils disposed on opposite sides of the power generation unit with their leading edges facing a windward end of the power generation unit; a body element having a curved front face and a back disposed, wherein at least a portion of the elongate body element is disposed between the first and second set of airfoils; and a power generation unit disposed in alignment with the body element, the power generation unit including at least a housing, and a turbine and an electrical generation unit actuated by the turbine disposed within the housing. As a fluid flows across the airfoils, the lifting force of the airfoils causes a reduced pressure within the power generation unit, drawing air past the turbine, through the body element and out the back of the body element, thereby extracting power from this secondary fluid flow stream.
