20150013325 | WAVE ENERGY CONVERTER SYSTEM - The invention is a wave energy device which optimizes energy conversion from waves with a stable submerged platform coupled to compliant chain of floats (“pods”) which are connected to the platform by piston pumps. Wave action drives pumps to deliver pressurized water to a hydro turbine coupled to an electric generator for delivery of electric power to shore via a submarine cable. Alternatively, the pressurized water may be delivered to shore through pipes on the ocean floor, to generate electric power, also as input flow for reverse osmosis potable water production and for cooling applications. | 01-15-2015 |
20110304144 | Method and apparatus for converting ocean wave energy into electricity - A power-generating device located in or on the surface of the ocean for generating power utilizing the energy in ocean wave motion. The device is moored to the bow and stern at ˜45° to incoming ocean waves, and with a yawing capability to adjust to change in wave direction. The device delivers power to a shore grid via a submarine cable from a generator. A rotational driving torque to the generator is produced by two long counter-rotating drive tubes, which are held by bearings in the bow hull and the stern hull of the device. As an alternative, hydraulics may be employed for energy capture and power smoothing and used to provide the rotational torque through a hydraulic motor to drive a generator. The main body is partially submerged and has multiple pod floats connected to the structure by rocker arms with bearings through which the drive tubes pass or double-acting hydraulic rams between the arms and the main body, which capture energy through pod displacement and store it in accumulators. Rotary torque of the drive tubes is produced when the pods move up and down according to motion of the waves and is transmitted to the generator to generate power. In the hydraulic case, energy is stored in accumulators as pressure due to the double-acting hydraulic pistons pumping when the pods move up and down according to the motion of the waves. Hydraulic pressure drives a pump, which provides torque to the generator. | 12-15-2011 |
20100276935 | RENEWABLE ENERGY FLUID PUMP TO FLUID-BASED ENERGY GENERATION - A wind or water turbine mounted atop a support tower or tethered underwater drives a hydro-pumping system. The turbine converts wind or water energy into a driving torque applied to the hydro-pump. The hydro-pump forces water through a pipe transmission system to an onshore facility. On shore, the resultant pressurized fluid-flow propels a hydroelectric generating system to produce electricity or may first be used in a Reverse Osmosis desalinization process and the byproduct in part used to propel a hydroelectric generating system to produce electricity. The cold-water discharge from the hydroelectric generating system and/or from the desalinization process is used for onshore district or power plant cooling purposes. | 11-04-2010 |
