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.

Systems and methods disclosed herein provide a tidal power generator including a first container, a second container coupled to the first container, a frame pivotably coupled to the second container, a first valve, associated with the second container, configured to selectively control ingress of a first volume of a fluid into the second container, and a second valve, associated with the second container, configured to selectively control egress of a second volume of the fluid out of the second container.

Systems and methods for capturing renewable energy are disclosed herein. An example system can include a concave receptacle configured to float on top of water, a turbine positioned centrally with the concave receptacle, a buoyancy control system having a pump and one or more vessels, a controller having a processor and memory for storing instructions, the processor executing the instructions to cause the buoyancy control system to submerge the concave receptacle under the water by filling the one or more vessels with a fluid using the pump and cause the buoyancy control system to release the fluid from the one or more vessels and allow the concave receptacle to travel upwardly so that water is directed into the turbine to produce electricity.

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.

The invention relates to a floating vessel (1) for energy harvesting, comprising:a hull (2), and a wave power plant (10). The wave power plant comprises:an inlet (11) arranged to receive waves of water, said inlet (11) leading to a transport channel (12) arranged with an angle to convey and lift water entering the inlet (11),5said transport channel (12) leading to an elevated basin (13) arranged to receive water, and said basin (13) having an outlet to a turbine (14T) below said basin (13), said turbine (14T) running an electrical generator (14G) for converting the potential energy of the water to electrical energy.
