Structurally the equipment of the present invention is characterized by comprising a float having an orifice in the center, in this orifice it is disposed firmly fastened a rigid pipe hydraulically connected at one of its ends to a hose, and at the other end to a check valve in the end immersed in the water bed; the opposite end of the hose which is hydraulically joined to the rigid pipe, the hose ends in a water tank on dry land and above the sea level average. | 10-21-2010 |
| 20110120109 | FALLING WATER ELECTRICAL GENERATORS AND ELECTRICAL GENERATING METHODS - A power generator is provided having one or more reservoirs. Each reservoir has an inlet and an outlet. A float is disposed in each reservoir. A shaft is connected to each float. Controls are provided for actuating each inlets and outlet to cause water to flow into and out of each reservoir via its corresponding inlet and outlet, respectively. As a result, the flowing water moves each float in a vertically oscillating manner to rotate the shaft at an output a rate suitable to generate usable power. Also provided are a method for generating electricity and an energy converter that converts vertical float movement into rotational energy. | 05-26-2011 |

Each reservoir has an inlet and an outlet. A float is disposed in each reservoir. A shaft is connected to each float. Controls are provided for actuating inlet and outlet gates to cause water to flow into and out of each reservoir via its corresponding inlet and outlet, respectively. As a result, the flowing water moves each float in a vertically oscillating manner to rotate the shaft at an output rate suitable to generate usable power. | 01-12-2012 |
| 20130333372 | HIGH-EFFICIENCY WIND POWER GENERATORS USED AS HYDROKINETIC ENERGY CONVERTERS ON BRIDGE AND OTHER STRUCTURES - In this invention, high-efficiency wind power generators are mounted on floats that are attached to bridge and other structures for generating electricity from hydrokinetic energy in water waves, currents and tides without submerging the wind power generators in the water. The use of bridge and other dual-use structures substantially reduces the capital cost necessary for installing this system to generate electricity in small as well as large amounts. Today, the systems for converting wind energy to electricity are far more advanced and efficient than existing systems for converting hydrokinetic energy. This invention could produce energy for water-transport vessels as well as for electric utilities. | 12-19-2013 |
| 20140075932 | WAVE POWER CONVERTING DEVICE - A wave power converting device includes a platform, a plurality of first and second fluid guide assemblies and floating assembly. The platform has a retaining post anchored to an underwater ground. The first and second fluid guide assemblies are disposed underwater so that the water could flow into the first and second fluid guide assemblies. The floating assembly could be moved up and down relative to the platform so as to press the water upwardly through the first and second fluid guide assemblies to a reservoir. Under this arrangement, the energy potential of the water in the reservoir can be converted into electrical power. | 03-20-2014 |
| 20140157767 | FREE FLOATING WAVE ENERGY CONVERTER - A free floating wave energy converter includes a flexible pine and an inlet. The flexible pipe floats on water surface, following the wave form. Slugs of water and air enter, one after the other, through the inlet. Because the flexible pipe follows the shape of the wave, water is transported through a manifold to a pressure chamber connected to a generator. The inlet consists of hollow, inflexible pipe attached to the throat of the flexible pipe. The inflexible pipe is fixedly attached to a buoyancy tank or plurality thereof. The buoyancy tanks are arranged in a vertical plane or in tandem, with the inflexible pipe passing along the plane vertical to the fore and aft axis of the buoyancy tank and the frontward portion projecting sufficiently ahead of the buoyancy tank with the flexible pipe terminating at a singular outlet. | 06-12-2014 |
| 20140230427 | WAVE ENERGY APPARATUS HAVING A VENTURI SHROUD - By optimizing the degree to which water is accelerated through a venturi device, the amount of power that an energy device extracts from the ocean is maximized. Prior venturi-based wave energy devices have proven to be inefficient because of the relatively small amount of power that they generate relative to their size and cost. By optimizing the venturi effect created within the submerged venturi components of such devices, the speed of the water moving through the narrowest portions of such a devices is maximized with respect to the wave environments in which they operate, and a maximal amount of energy is extracted from the ocean. This optimization of a wave energy device's power is sufficient to render such devices cost effective. The method of extracting energy from the accelerated flow of water moving through such venturi devices is not limited, and many alternatives exist, each with its own potential benefits. | 08-21-2014 |
