    Abstract: The invention captures harvestable mechanical energy, e.g., in the form of wind or moving water, and uses it for electrical generation or other work. In various embodiments a turbine is used to pressurize a fluid, and the pressurized fluid is then optionally stored and then used to drive an electric generator. Because the pressurized fluid can be stored in a pressurized state indefinitely, the invention provides a straightforward way to accumulate the mechanical energy until it is needed. Additionally, the invention allows portions of the system, e.g., a pressure vessel or generator, to be located away from the turbine, reducing the costs of deploying and maintaining the system.

  • Publication number: 20140182278
    Abstract: An apparatus and method is provided for generating net energy by converting the natural pressure of atmospheric air into kinetic energy, which is then converted to mechanical energy by a turbine, which can then be converted to electric energy through a generator. The method relies on natural physical phenomena such as Entrainment, Inducement and the Venturi Effect to increase the mass and velocity of air flowing through an enclosed chamber without increasing the amount of energy consumed to increase the air flow mass and velocity. A turbine-generator apparatus connected to the chamber is driven by the air flow to generate electric power which is greater than the power consumed to generate the initial air flow. Power is generated through extraction of kinetic energy from natural atmospheric air pressure energy.

  • Patent number: 8763386
    Abstract: This invention captures hydrokinetic energy to do work such as produce electricity. The hydrokinetic flow exerts a torque on a turbine wheel. The wheel causes a set of tanks to rotate around a horizontal centerline. Working fluid drains from tanks near the top of the wheel to drive a conventional turbine before draining into lower tanks. Although a mechanical power transmission driven by the turbine wheel is simpler in concept, scale up to large slowly rotating wheels encounters increasingly difficult design problems: transmission of 1 kW at 1 rpm requires 6,959 ft-lb. In contrast, the conventional turbine of the fluid drive system provides mechanical power for use at a much higher speed than the turbine wheel. Therefore, very large engines can be built without a step-up transmission or components that must withstand extremely large torque loads. One unit can produce reliable 24/7 utility-scale base-load electrical power.

  • Patent number: 8614522
    Abstract: An energy converting device, particularly for converting mechanical energy to hydraulic energy and from it into electrical energy, uses as an energy transport medium, a control fluid guided in two different control circuits. The control circuits have an operative connection to each other by a coupling device (32). One control circuit (28) serves for feeding in energy, particularly in the form of mechanical energy. The other control circuit serves for discharging energy in the form of converted energy, particularly electrical energy.

  • Publication number: 20130320683
    Abstract: This is a power generating technology that uses gravity as its fuel supplies. This technology harnesses the power of gravity without any dependable sources like hydro, wind, petroleum products etc. and generates power supply. The technology is based on a simple theory which basically states the output energy is possible, if certain mass rotates under gravity and when small amount of the energy generated by the movement of that mass is applied towards the direction of same moving or falling mass. The technology is possible because the mass is used as an independent source of fuel, which is caused, by the combined act of gravity and transformation of energy through assist circuit. My prototype has become the self-evidence that it can be used as a power generator or a motor for industries and harvest energy without any dependable sources.

  • Patent number: 8598729
    Abstract: A wave power plant is disclosed which has one or more foils that are pivotally movable about a body. The foil is set into an oscillating, pivotal motion about the body by the force of the waves. A power engine is mounted between the body and the foil and extract works as the foil pivots about the body. The foil and body are held submerged below the surface of the water to reduce the effects of extreme weather conditions on the structural components.

  • Patent number: 8587145
    Abstract: A wind turbine for power generation includes a vertical axis hydro kinetic wind generator with an independent free turning magnetically levitated high powered magnetic translator stack. The wind turbine converts high pressure hydraulic kinetic energy stored in the high pressure reservoir into mechanical energy that drives the vertical axis linear generator. The high pressure reservoir, hydraulic pump motor, microprocessor controller and algorithm software and the fully levitated vertical axis linear generator along with light weight sail blades are instrumental for improved operation.

  • Patent number: 8561398
    Abstract: A power generating system operates in a flowing body of fluid, such as water or air. The system includes a continuous loop member engaging and rotating around two rotatable members, which, in turn, are operatively connected to a generator. The continuous loop member can include a plurality of attachment arms that extend outwardly therefrom. A collapsible fluid catchment device can be attached to each attachment arm. The fluid catchment devices can open in the direction of movement of the water thereby driving the continuous loop member and, consequently, the rotatable members. When moving against the fluid flow, the catchment devices can collapse to a closed position to thereby reduce drag. The attachment arms are long enough so that the catchment devices are spaced a sufficient distance from the continuous loop member to prevent contact with the rotatable members and the continuous loop member when the catchment devices are fully open.

  • Patent number: 8561399
    Abstract: A compressed-air energy storage system according to embodiments of the present invention comprises a reversible mechanism to compress and expand air, one or more compressed air storage tanks, a control system, one or more heat exchangers, and, in certain embodiments of the invention, a motor-generator. The reversible air compressor-expander uses mechanical power to compress air (when it is acting as a compressor) and converts the energy stored in compressed air to mechanical power (when it is acting as an expander). In certain embodiments, the compressor-expander comprises one or more stages, each stage consisting of pressure vessel (the “pressure cell”) partially filled with water or other liquid. In some embodiments, the pressure vessel communicates with one or more cylinder devices to exchange air and liquid with the cylinder chamber(s) thereof. Suitable valving allows air to enter and leave the pressure cell and cylinder device, if present, under electronic control.

  • Patent number: 8564152
    Abstract: This invention is an apparatus and method for harnessing water wave energy by transforming it into a continuous flow of water to be converted into mechanical work by means of a water turbine which in turn actuates a generator that transforms the work in to electrical energy. The wave energy device connects distanced water waves in a novel manner that allows them to power one another rather than only themselves alone. By interposing a turbine in the communicating flow of water that transmits power from each wave to the others energy can be siphoned from them and stored for human use.
