060500000 | Having articulated buoyant members | 6 |
20110061377 | WAVE ENERGY COLLECTING DEVICE - Wave energy collecting device comprising an array of modules ( | 03-17-2011 |
20110308244 | MODULAR ARRAY TYPE ENERGY CONVERTER - A wave energy transformation device including an array of members connected together to form a structure having a substantially hexagonal geometry, the array has link members, nodes and absorbers and the relative motion of at least some of the members of the array, as caused by the energy of wave motion in a medium to which the array is coupled is convertible to another form of energy. The device is suitable for generating electrical energy from sea waves. | 12-22-2011 |
20120000193 | Tidal energy system - A tidal energy capture means connects a turbine to its anchor by telescopic members which pivot about the anchor as axis in the plane of the tidal flow and whose combined length depends upon the force of this flow. These members can be locked at prescribed lengths by a remote signal, to control the level of the turbine during this movement. The anchor consists of a plug and socket, with buoyancy means for positioning the plug in the socket, and the telescopic members can be a rotatable shaft which drives equipment in the plug. | 01-05-2012 |
20130055707 | DEVICE FOR RECOVERING SWELL ENERGY - The invention relates to a device for recovering the energy of sea waves comprised of a floating structure comprising:—a rigid structural element ( | 03-07-2013 |
20140116042 | WAVE POWER GENERATION SYSTEM AND HYDRAULIC COMPONENT THEREOF - A wave power generation system includes a power generation component and a hydraulic component. The hydraulic component includes a cylinder and a piston. The cylinder connects to the power generation component. The cylinder has an accommodation space and a vent located in the middle section of the accommodation space such that the vent runs outside from the accommodation space. The accommodation space is used for accommodating a fluid. The piston is disposed in the accommodation space and is used for being guided by the accommodation space and sliding relative to the cylinder. Thereby, this drives the power generation component to convert mechanical energy into electrical energy, and to force the remaining air in the accommodation space and remaining air in the fluid to be discharged via the vent. | 05-01-2014 |
20150082785 | Wave Energy Converter With Concurrent Multi-Directional Energy Absorption - An ocean wave energy converter (WEC) using one or more elongated light-weight low-cost surface floats, oriented and self-orienting parallel to oncoming wave fronts are mechanically linked to a motion stabilized or fixed frame or base through one or more power take-offs in such manner that multi-directional rotational and translational wave-induced forces and relative motion between the float(s) and base are efficiently captured. Some embodiments have at least one forward positioned float that moves upward and rearward on wave crests and downward and forward on ensuing wave troughs to capture a majority of both heave and surge wave energy components. Other embodiments also provide apparatus and means to totally submerge the floats during severe seas or adjust submerged depth and float mass to optimize performance. | 03-26-2015 |
