The power take-off system further comprises control means (50) configured to instruct the electric generator (32) and the variable-displacement hydraulic pump (41) to convert mechanical energy from the rotary shaft (31) into electrical and hydraulic energy, respectively, upon energization of the rotary shaft (31) by the prime mover (60), or to instruct one of the electric generator (32) and the variable-displacement hydraulic pump (41) to convert mechanical energy from the rotary shaft (31) into electrical or hydraulic energy, respectively, and the other one of the electric generator (32) and the variable-displacement hydraulic pump (41) to introduce mechanical energy to the rotary shaft (31). The invention also relates to a wave energy converter comprising such a power take- off system, and a method of operating it.

2. WO/2017/085647 AN APPARATUS FOR POWER GENERATION FROM THE SURFACE OCEAN WAVES IN DEEP SEASWO26.05.2017
F03B 13/14
PCT/IB2016/056908AVADHUTA, Pruthvi RajAVADHUTA, Pruthvi Raj
Exemplary embodiments of the present disclosure are directed towards an apparatus for power generation from the surface ocean waves in deep seas and methods thereof. Wave energy moves a float, vertically up and down, within the confines of four vertical pillars that are fixed to a buoyant tank. This buoyant tank is placed deep below the ocean surface and the upper surface of the float connects to a rack and pinion system which is coupled to a gearbox. Within the gearbox are freewheels and gears, that drive a generator shaft, in one direction only, as the float oscillates up and down on the ocean waves. For generating large amounts of power, a number of units are placed in a row. Many rows are placed side by side and the mechanical energy of all the rows is transferred to a long horizontal shaft which drives a generator through a gear box.

3. WO/2017/086693 AUTONOMOUS POWER GENERATING DEVICE USING GRAVITY AND BUOYANCY, AUTONOMOUS POWER GENERATING DEVICE USING STRUCTURE, AND MARINE BOUNDARY LIGHT USING SAMEWO26.05.2017

PCT/KR2016/013210JUNG, Min ShyJUNG, Min Shy
The present invention relates to an autonomous power generating device using gravity and buoyancy, an autonomous power generating device using a structure, and a marine boundary light using same. To this end, the present invention forms a rotating module having at least one rotating body provided on a rotating shaft and a power transmitting gear provided on one side end of the rotating shaft, a rope is hung to touch the rotating body of the rotating module and moves upward and downward, a buoyant body is provided on one side end of the rope, a tensioning body is provided on the other side end to vary the vertical force with the buoyant body, and the rotating force of the power transmitting gear of the rotating module is sequentially transmitted to a drive gear and a generator. Therefore, a fluctuation in water level can effectively be converted into an up-and-down vertical movement of the buoyant body.

4. WO/2017/087581 SYSTEM FOR PRODUCING ENERGY VIA USE OF GRAVITYWO26.05.2017
F03B 13/06
PCT/US2016/062370KAROUSOS, John, A.KAROUSOS, John, A.
The present invention is a system for producing energy via use of gravity and then integrating such a force into a system design of energy power generation by translating the force of gravity into potential energy then into kinetic energy and from kinetic energy back into potential energy again. This system can operate 100 % mechanically or 100% electromechanically by its own power generation, without the need to utilize the aid of an external source of energy or, if required, with the aid of a minimal amount of external energy. A mechanical sequence is introduced in the system's operation to prolong the operational functionality of motion to its working components to the point where full, or substantially full, and independent recycling of fluids takes place and in the process it generates power to run the system's electricity producing generators and supply electricity to the power grid.

14859077Charles B. CulpepperCharles B. Culpepper

The invention disclosed herein comprises a system focusing water current into a relatively smaller diameter lumen, imparting vortical movement to the current, and directing the water vortex through an even smaller diameter lumen en route to turbine blades having long curved blades rotatable along an axis parallel with the lumen. Rotation of the turbine blades turns gearing interfacing with the circumference of the turbine assembly, to rotate a drive shaft connected to a generator.

H02N 1/00
15339021Mizuki OTAGIRIMizuki OTAGIRI

A power generating element is provided. The power generating element includes an electrode pair and an intermediate layer. The electrode pair includes a first electrode and a second electrode. The intermediate layer is disposed between the first electrode and the second electrode. The intermediate layer is insulating and has a first side facing the first electrode and a second side facing the second electrode. The first electrode and the intermediate layer together operate as a contact/separation mechanism configured to perform a contact/separation operation, when an external force is applied to the power generating element to generate power. In the contact/separation operation, the contact/separation mechanism transitions between a contact or close state in which the first electrode and the first side are brought into contact with each other or close to each other, and a separation state in which the first electrode and the first side are separated from each other.


8. 20170145982 SUBMERSIBLE TURBINE GENERATORUS25.05.2017
F03B 13/10
14934280Barry G. HealdBarry G. Heald

A submersible turbine generator unit can be placed in rivers, streams, or anywhere water flows in order to generate electricity without the need for dams. It is designed to work with its own diversion equipment for controlling and directing a flow of water into the turbine blades. The unit can be raised and lowered in the flow to enhance efficiency, respond to changing flow conditions, and for inspection/servicing, etc. The positioning system can use a motorized worm gear and a rack to raise or lower the turbine generator combination. Once raised up, a hard connection point allows attachment of a lifting cable so the turbine/generator combination can be easily removed and replaced as needed. A submersible turbine generator utilizes uniquely shaped turbine blades that efficiently engage flowing water and spin the turbine shaft without presenting undue risk to aquatic life.

F03B 13/18
15322269Christian CARMEChristian CARME

The invention relates to an installation having at least one caisson positioned at a given depth in a marine environment, said caisson including a rigid tank in which an oscillating plate moves, said oscillating plate being adapted to oscillate in relation to a vertical axis depending on fluctuations in the height of the water column created by the swell perpendicular to the plate, said tank and plate defining a chamber. The installation is characterised in that the chamber is sealed by a flexible hermetic pouch which is filled with a gas and deforms according to the oscillations of the oscillating plate, the pressure of the gas inside the pouch being adjusted so as to compensate for all or part of the weight of the water column perpendicular to the plate in the absence of swell.
