| 20100111696 | Counterbalanced orthogonal hydropower system - A counterbalanced orthogonal hydropower system for generating electricity comprises -an upper and lower turbines made as ring-shaped platforms, each incorporating a rotor, the turbines include hydro-dynamical blades positioned to rotate the turbines in opposite directions, -variously disposed inductors, -a tower mounted on a water reservoir's bottom, -a frame, supported by the tower and peripherally surrounded by a rigid polygon-shaped structure having vertexes, -units for rotatable support of the turbines associated with the frame, and -units for support of the inductors, wherein the latters are attached to the vertexes through spring-loaded hinges. It may also comprise units for support of the circular shape of platforms, for braking rotation of the turbines, for unloading the turbines from lateral forces, and for unloading the turbines from vertical forces. The top turbine may have negative buoyancy, while the bottom turbine and frame may have positive buoyancy. The frame can be made of hollow rods. | 05-06-2010 |
| 20100143130 | INFLATABLE WIND TURBINE BLADE AND METHOD FOR FORMING SAID ROTOR BLADE - An inflatable rotor blade for a wind turbine includes a flexible skin. The flexible skin assumes, when inflated by means of an inflation medium, the shape of an airfoil which has an inner cavity. When the inner cavity is formed, at least one stiffener unit is arranged in the inner cavity of the rotor blade and maintains the airfoil shape of the flexible skin. | 06-10-2010 |
| 20100266406 | Turbine Arrangement - A turbine arrangement for extracting energy from flowing water, the turbine arrangement s including a screw turbine with a suspension means, buoyancy element and bottom mount, and necessary transmission elements for transmitting energy to a power machine, and the turbine arrangement including at least two parallel screw turbines. | 10-21-2010 |
| 20130034441 | MULTIPLE-LAYER STRUCTURE OF INFLATABLE DEVICE CAPABLE OF PRESSURE RESISTANCE - A multiple-layer structure of inflatable device capable of pressure resistance includes a gasbag unit and a reinforcing shape-forming net. The gasbag unit includes a gas inlet, a flexible waterproof inner tube for fluid communication with the gas inlet, and a flexible material of outer tube covering the flexible waterproof inner tube, wherein the gasbag unit and the reinforcing shape-forming net covering the gasbag unit are both in independent structures. When the gasbag unit become expanded over the reinforcing shape-forming net, the reinforcing shape-forming net will resist the applied force from the gasbag unit, so that the gasbag unit can be made of a light weight material and thus the maintenance and renew become easy. The present invention is not only easy in maintenance but also efficiently reducing cost for all kinds of inflatable products and environment protection. | 02-07-2013 |
| 20130224020 | Floating Hybrid Composite Wind Turbine Platform and Tower System - A wind turbine platform is configured for floating in a body of water and includes a hull defining a hull cavity therein. The hull is formed from reinforced concrete. A tower is configured to mount a wind turbine and is also connected to the hull. An anchor member is connected to the hull and to the seabed. | 08-29-2013 |
| 20130251527 | Sail Enhanced Wind Turbine System - The Sail Enhanced Wind Turbine System will increase the output of the wind turbine within the system by increasing the amount of force, or wind, being applied to the turbine. | 09-26-2013 |
| 20140105742 | Emergency inflation Kayak, Canoe paddle - This invention provides rapid, on-demand increase in buoyancy of a kayak or canoe paddle. The invention includes any method to increase paddle buoyancy including but not limited to automotive air bag technology (explosive gas), compressed gas or other means. The paddle shafts are hollow and can contain all the devices to provide the inflation. Multiple triggers on the shaft and handle provide for positive operation only when demanded by the paddler. | 04-17-2014 |
| 20140248151 | FLOATING WATER WAVE ENERGY COLLECTING AND TRANSDUCING SYSTEM - Provided is a floating water wave energy collection and conversion system, which comprises at least two buoyant members ( | 09-04-2014 |
| 20150086364 | UNDERWATER PROPELLER DEVICE WITH PULSED JETS - A device, which is autonomous or which can be associated with another structure, for propulsion in a liquid environment is described. The device has a bladder body made of a soft material, developing along and around a central longitudinal axis, defining an internal chamber between a dorsal wall and a ventral wall; in the bladder body, an inlet opening and an outlet opening of a liquid in and out of the chamber, arranged at a longitudinal end of the body; and drive means for driving a contraction of the bladder, arranged on the dorsal wall and having a mechanical connection with the ventral to cyclically attract the ventral wall to the dorsal wall, thereby causing a pulsed ejection of a propeller jet from the chamber through the outlet opening. | 03-26-2015 |
| 20160138554 | POWER GENERATING SYSTEMS - Power generating equipment includes a support structure adapted to be disposed on the bed of a body of water having a surface above the bed; and a buoyant power generating apparatus having positive buoyancy releasably connectable to the support structure, the power generating apparatus being adapted to be released from the support structure and to make controlled free ascent to the surface of the water following such release. | 05-19-2016 |
