20090165455 | METHODS AND APPARATUS FOR ENERGY PRODUCTION - The present invention discloses an energy production system comprising a liquid reservoir in which a liquid periodically changes its level, at least one float at least partially immerged in liquid within said liquid reservoir, a lock system operable to maintain said float at a predetermined base level in said liquid, and a controller system comprising a floating trigger system operable to selectively trigger said lock system to release the float from the base level to wave crest thus enabling an outburst and creating high mechanical energy, thereby producing energy power from the liquid level difference within said liquid reservoir. | 07-02-2009 |
20090211240 | Method and apparatus for converting energy in a moving fluid mass to rotational energy driving a transmission - Three bodies interact to drive a transmission having a pair of one-way clutches coupling a single length of drive chain or other elongate flexible member to an intermeshed pair of counter rotatable gears so as to drive a primary shaft in a single rotational direction. The three bodies are a fixed body, a floating body, and a suspended and usually submerged weighted body. The three bodies are interconnected by the single length of the elongate flexible member and are spaced apart there along. The weighted body is mounted at one end of the elongate flexible member. The primary shaft is mounted above the surface of a moving fluid mass to either the fixed or floating body. The end of the flexible member opposite to the weight is mounted to the other of the fixed or floating body. | 08-27-2009 |
20100043424 | SYSTEM FOR GENERATING ELECTRICAL POWER AND POTABLE WATER FROM SEA WAVES - The invention pertains to a device and method for generation of electrical power from sea waves, with either simultaneous or no desalination of seawater. The device comprises a seaborne portion and a shore-side portion. The seaborne portion of the device comprises a float, an anchor and a pumping mechanism. Seawater and air are drawn in and pumped through pipes and respectively to a shore-side compressor system. The compressor system is adapted to provide pressurized water of constant pressure to the next stage, which is either the desalination assembly through which potable water is produced using the reverse-osmosis method or the water-motor, which drives a generator that provides electrical power or both. | 02-25-2010 |
20110061376 | ENERGY CONVERSION ASSEMBLIES AND ASSOCIATED METHODS OF USE AND MANUFACTURE - Embodiments of the disclosure are directed to conversion of renewable energy such as solar, wind, falling water, wave and biomass resources into energy forms for practical transport by existing electricity and natural gas transport systems and includes embodiments for cyclic conversion of rectilinear forces into electricity wherein charged particles force a separate population of charged particles to flow in a separate circuit to create an electric current. Forces exerted at a first frequency are converted into cyclic electrical current at a frequency that is a multiple of the frequency of the forces. Similar arrangements are provided for conversion of rotary forces into electricity. Components of the disclosure can be manufactured at a high rate from very low cost materials with minimum energy requirements for the purpose of generation of low-cost electricity from linear motion engines and renewable forces such as ocean waves and flowing fluids such as water or air. Corrosion and biofouling are eliminated by application of cathodic and chemical treatments produced by the operation of the disclosure. Various embodiments of the disclosure allow improved cogeneration and motor vehicles, household appliances, and industrial equipment to be operated on energy converted from rectilinear forces. | 03-17-2011 |
