This invention discloses a method and a device for the capture of wave power, exploiting the maximum potential energy of each wave, based on obtaining the maximum imbalance possible between the Thrust Force and the Weight acting upon the capture elements on the passage of each wave, slowing and releasing them both at their high points and at their low points by means of the use of blocking systems, maximizing the submerged and emerged volumes of the next movement, likewise the travel during which the capture elements are accelerated due to the exploitation of their kinetic energy and their release in the transmission of efforts at the moments when the points of equilibrium between the rising and falling maximums are reached, thus generating an increase in the potential energy captured.

The present invention relates to the utilization of wave energy and its conversion into operating motion of an electrical energy generating system. The system for generation of electrical energy through the conversion of aquatic wave motion includes floating bodies and a constant rotation mechanism, which converts the two-way linear motion of an inflexible transmission shaft or a flexible transmission shafts into one-way rotation of an output shaft of the constant rotation mechanism. This mechanism allows utilization of wave energy in two directions caused by the rise and fall of waves. The output shaft of the constant rotation mechanism is coupled to a force multiplier that is further coupled to a generator which generates electrical energy. Constant rotation mechanism can be driven by inflexible transmission shaft pivotally coupled to the floating bodies at one end, and the other end to an input gear of the constant rotation mechanism. Depending on the height of the wave and the wavelength, various constructions of floating bodies are used. Certain floating bodies are designed for the waves of a smaller amplitude and smaller wavelength, while other floating bodies are designed for bigger amplitude and bigger wavelength.

A tidal power generation system has a vertical post being embedded in a sea floor and a floating barge operably coupled to the post. The floating barge has a gear rotationally driven by the post as the floating barge moves vertically with respect to the vertical post. An offshore hydraulic pump is operably connected to the gear, an onshore hydraulic motor operably connected to the offshore hydraulic pump by a hydraulic circuit; and an electric generator is operably connected to the onshore hydraulic motor.

Device for storing energy, using a physical object, such as a mass or buoyant object floating in fluid. A mass is repositioned to greater altitude in a gravitational field to a position of higher potential energy. A buoyant object is forcibly submerged into a fluid, displacing fluid, to a position of higher potential energy. The stored potential energy may be recovered with extremely low loss regardless of the state of charge of the system, or length of time of the storage. Maintaining the charge is indefinitely lossless.

The present disclosure provides a method and related systems for converting the alternating motion produced by an array of floats resting atop the surface of a body of water into unidirectional motion and converting that motion into usable energy on a common structure. A vessel constructed as such is also provided which experiences a reduced effect of vertical perturbations from waves. There is also provided a method for a standalone system using a float and a connected or merged hydrofoil to generate usable unidirectional motion from water waves.
