  • Patent number: 9878265
    Abstract: A system for producing potable water and electrical power utilizing the difference in temperature between ambient air and deep, cold ocean water is disclosed. Cold water from depths of 2000 feet (610 meters) or more is pumped to a liquid/gas heat exchanger in the upper portion of a hollow cylinder. Ambient air currents are concentrated and diverted into the exchanger, becoming cooler and denser. Moisture condensing from the ambient air onto the cool surface of the heat exchanger is collected and channeled to storage or piped to shore. The air gains velocity before reaching a wind turbine near the bottom of the cylinder. This turbine is connected to a generator to extract the wind energy. This extracted energy is converted to electricity by the generator and sent to shore.

  • Patent number: 9745952
    Abstract: The various embodiments disclosed herein provide a generalized system for extracting gravitational energy from the planet and provide for a general, pollution free, mass lifting and energy conversion system in which the laws of fluid flow, and in particular buoyancy and gravity are utilized to lift an arbitrary mass to a higher gravitational potential energy, where upon the increased potential energy can be converted to other forms of energy. Novel and non-obvious features of the fluid interface device, used to insert the buoyant object into the buoyant fluid, insure that the insertion energy is less than the potential energy gained by the object. The net increase in potential energy can be converted to other forms of energy such as electrical power or mechanical energy. It is shown in that energy gain is effectively extracted from the gravitational field of the planet without breaking the laws of conservation of energy.

  • Patent number: 8713933
    Abstract: An apparatus and process for capturing mechanical work from the kinetic energy of a moving vessel driven by buoyancy and gravitational forces. The apparatus comprises a moving vessel, gas compression means, force transfer means, a conduit, and a force recovery means. In use, the submerged moving vessel receives compressed gas, generating a buoyancy force in the moving vessel. As the moving vessel rises in water and approaches the top of its upstroke, the moving vessel releases the gas, causing the moving vessel to sink. A first component of the buoyancy force is transmitted from the moving vessel, through the force transfer means, to the gas compression means, where it compresses gas. The compressed gas is channeled through the conduit into the charging valve while the moving vessel sinks. The charging valve releases the compressed gas from the conduit into the moving vessel, and the moving vessel's vertical oscillation cycle repeats.

    Abstract: The present invention relates to a hydraulic energy store (1) having a first (2) and a second fluid reservoir (6), the fluid levels (4, 12) of which extend at different heights, which are connected to one another via a turbine/pump arrangement (10) and during the operation of which a fluid (3) can be moved to and fro between the first (2) and second fluid reservoir (6) and energy can be converted in the process. The second fluid reservoir (6) is configured as a container which is arranged within the fluid (3) in the first fluid reservoir (2), wherein, during operation, the fluid level (12) in the second fluid reservoir (6) can be changed in such a way that, as a result, the immersion depth (h1) of said second fluid reservoir (6) in the first fluid reservoir (2) can Ere changed owing to buoyancy.

  • Patent number: 8640460
    Abstract: An ocean wave electrical generating system is described. The generating system is adapted to harness the energy of ocean waves in a wide variety of applications and conditions. The system reduces the effect of the variable input energy from ocean waves by initially storing the energy in the form of potential energy and subsequently transforming the potential energy to kinetic energy. The release of kinetic energy is coupled with generators which are isolated from the effects of the variable input energy into the system by this process. This system is developed to utilize the variable potential energy available and to provide a constant kinetic energy output.

  • Publication number: 20140007567
    Abstract: A reaction mass and a spring are configured to form an “oscillator”. The reaction mass is coupled to, and can wrap around, a first pulley via a first belt/cable. The spring is coupled to, and can wrap around, a second pulley via a second belt/cable. The first and second pulleys are mechanically linked together and are mounted so they rotate in tandem. The diameter of the second pulley is different than the diameter of the first pulley to cause the reaction mass to travel a different distance than the spring in response to the up down motion of the reaction mass. The first and second pulleys may be circular with the second pulley being made smaller than first. Alternatively, the first pulley may be circular and the second pulley a cam of varying radius.

  • Publication number: 20130333382
    Abstract: The present invention is a power source machinery. The power source machinery has following functions. Firstly, a slow cyclic flow is generated in a first period, and a quick and slow cyclic flow is generated in a second period. Secondly, a first huge generator drives a cylinder to rotate slowly from beginning to end, and outputs a lot of electric energy. Thirdly, supply of rotary power to a second generator and a third generator is stopped, and the rotary power is transferred to a gas pump and a water pump, which are rotating to finish the quick cyclic flow. In every period, the quick flow raise liquid in a single water-caltrop-shaped element in a lower portion to a single water-caltrop-shaped element in a higher portion, which has a function of lever, in such a manner that the power source machinery rotates continuously for a long period.

  • Patent number: 8601808
    Abstract: In accordance with the present invention, a Hydrokinetic & Wind Energy Harvester, placed in a wave-swash zone or in a flowing stream captures energy through water turbines and a wind turbine. A funnel guides water to converge and impinge on water turbines housed in a pipe. A trash guard attached to the funnel prevents trash from entering the pipe. A rotational transmission-system with one-way clutches transmits torque to an alternator to generate electricity. Flywheels maintain steady rotation of alternator shaft. A buoyancy chamber at the bottom produces reduction of weight of the unit in water, thereby enhances maneuverability of unit in water. Stabilization tank at the top when filled with water provides extra weight and stability against sliding and overturning of the unit in its operating location. An energy farm combines the energy of several units linked together; in coastal water, units form a seawall-like barrier mitigating coastal erosion.
