A method for operating a plurality of wind energy installations configured for supplying electric power to an electrical supply system, that each have an aerodynamic rotor with rotor blades and an electrical generator and also operating equipment, is disclosed. The wind energy installations are operated while they are not connected to the electrical supply system, where at least one of the wind energy installations produces electric power and inputs the electric power into a local DC voltage system that connects the wind energy installations if the at least one of the wind energy installations currently produces more power than needed for supplying its own operating equipment. Additionally or alternatively, the operating equipment is supplied totally or in part with power from the local DC voltage system if the at least one of the wind energy installations currently produces less power than needed for supplying its operating equipment.

Disclosed is a system and method for generating and storing energy from water waves. Oscillatory motions of a floating base are transmitted to adjustable weights enclosed in a container suspended from a frame that is rigidly installed inside the floating base. The container is operably coupled to a sheave, via a crank. The movement of the adjustable weights in the container results in the movement of a sheave that is operably coupled to an output shaft that is in turn coupled to an electric generator via a network of gears. The generator supplies power to an electrolyzer producing hydrogen and oxygen from water. The hydrogen and oxygen are compressed into gas or liquid and stored in containers on-board the floating base, until they are off-loaded at a facility.

A uniaxial power converting apparatus includes a floating unit into which the kinetic energy of waves is inputted and which is moored at sea by a wire, a direction change unit for changing a direction of the wire, and a power conversion module for transmitting the tension of the wire to a generator. The power conversion module can transmit a driving force to a power shaft to which the generator is connected from a drum around which the wire is wound.

An apparatus has at least one buoyant member pivotally connectable to an adjacent member and configured for relative movement about a first axis of rotation when acted upon by one or more incident waves. At least one pair of bevel gears are arranged to rotate about the first axis of rotation upon relative movement between the pivotally connectable members. The bevel gears mesh with a corresponding pinion gear which is attached to a rotatable drive extending substantially perpendicularly from the first axis of rotation. The pair of bevel gears are configured to engage the pinion gear in opposite directions respectively to drive the pinion and rotatable shaft to rotate in a single direction regardless of the direction of movement of the pivotally connectable members. The rotatable drive shaft is connected to a generator for the generation of electricity when the apparatus is subjected to incident water waves.

Systems and methods for use in capturing energy from natural resources. In one form, the systems and methods capture energy from natural resources, such as movement of fluid in a body of water, and convert it into electrical energy.

The present invention relates to a system of converting kinetic energy into electrical energy, comprising: at least one element that produces kinetic energy; a shaft coupled to the at least one element and configured to reciprocate in a vertical direction, whereby a linear movement of at least one element exerts a pressure for enabling the reciprocation in vertical direction, wherein said shaft serves as a vertically elevated poll; and a flywheel fastened to the shaft and configured to receive and store one-way rotational energy from said shaft, wherein the form of the shaft facilitate the rotational movement of the flywheel, thereby enabling to use the rotational energy for the generation of electricity.

The present invention is related generally to electric energy production and storage and more particularly to three devices that can work independently or as a system for generating, storing and retrieving of significant volume of green electric energy from sea and ocean waves.

The system could double the height and quadruple the power of any wave, harness and convert all the wave power to electrical energy, store it without loss for as long as needed, and release it when and as needed.

Apparatuses and methods are provided for facilitating air-cooling of, for instance, one or more electronics racks within a data center. The apparatus includes an air-moving assembly and one or more flywheels. The air-moving assembly includes a shaft, one or more mechanical fans coupled to the shaft to rotate, at least in part, with the shaft, and a motor coupled to the shaft to rotatably drive the shaft. The flywheel(s) is sized and coupled to the shaft of the air-moving assembly to store rotational energy, and to facilitate, for a specified period of time, continued rotation of the shaft during interruption in power to the motor. In one implementation, the flywheel(s) is sized and coupled to the shaft to facilitate, for the specified time period, continued rotation of the shaft at a specified percentage, or greater, rotational speed of the shaft compared with shaft speed when rotatably driven by the motor.

A system may include a stacking device having a base portion and one or more walls, the base portion having a first axle receiver that holds a first axle at a first defined position, the one or more walls extending from the base portion, the stacking device receiving one or more flywheel plates onto the first axle. A system may include a clamping device adapted to couple with the stacking device using one or more alignment mechanisms, the clamping device including a second axle receiver that holds a second axle at a second defined position, the first defined position and the second defined position being in line when the clamping device is coupled with the stacking device.
