  • Patent number: 7891186
    Abstract: A waste heat recovery system is provided for an internal combustion engine having a piston, a cylinder and an intake manifold, significantly improving gas mileage efficiency without reliance on alternative fuels. The system includes a heat loop having a heat transfer fluid, a compressor in fluid communication with the intake manifold to supply compressed air thereto, a Stirling engine operated and optimized via thermal communication with the heat loop, and operatively coupled to the compressor. The system includes a chiller in thermal communication with the heat loop, and with the intake manifold to cool the compressed air communicate to the cylinder. The system may include additional Stirling engines operating other devices, or being operated by a device, such as a propeller. A vehicle can incorporate the system and route fluid to and from a radiator. The system can be used in both portable and stationary applications.

  • Patent number: 7654073
    Abstract: A power-generating system is provided for operating adiabatically and reducing emissions of greenhouse gases contributing to global warming. The system may include gas reactors and/or combustors that burn a fuel and an oxygen-containing gas under substantially adiabatic conditions such that high-pressure combustion products and low pressure combustor housing cooling air are combined to produce a medium pressure working fluid. Higher thermal efficiencies reduce emissions of greenhouse gases. Products of combustion can be processed to further reduce emissions of carbon dioxide and other greenhouse gases from portable and stationary exhaust-producing devices using different fuels. The system may also include solar collectors that pick up a spectrum of solar energy by means of cells containing fluids, aligned to concentrate the solar rays. The collectors may pick up direct and/or diffused solar radiation and can be used to power self-propelled vehicles or function as a roof of a building.

  • Patent number: 7134285
    Abstract: An adiabatic power generation method and apparatus includes at least one combusting device to combust any suitable fuel and an oxygen-containing gas to produce hot high pressure combustion gases. Also includes modified present art combustors, wind and solar energy sources. A portion of the expanded gases, or ambient air is mixed with the combustion gases to form a mixture of gases as working fluid that is fed to a work-producing device.

  • Patent number: 6955052
    Abstract: A power generation method and apparatus includes a plurality of gas reactors that combust fuel and an oxygen-containing gas under substantially adiabatic conditions such that hot high pressure combustion gases flow alternately and substantially continuously from each reactor to a work-producing device wherein the combustion gases are expanded to provide work. A portion of the expanded gases, or ambient air can be mixed with the combustion gases to form a mixture of gases fed to the work-producing device.

  • Publication number: 20020100678
    Abstract: Hydrogen and Oxygen are ducted in the flame zone of a reactor chamber. A body of water and or steam is admitted into the outer zone of said reactor and with intimate contact with the flame zone will generate steam. Said steam is confluent with steam generated by combustion of said Hydrogen and Oxygen. Net steam flow is used externally for generating power, heating and cooling purposes.

  • Patent number: 5617608
    Abstract: A ram air duct directed to a vehicle's windshield receives ram air from behind a vehicle's engine coolant radiator which air is rammed through the radiator to heat the air and into the ram air duct by motion of the vehicle causing a heated air curtain over the windshield. During use at slow speeds, a fan may assist air movement from the radiator into the ram air duct. Supplemental heat may be obtained from electric heaters or the engine exhaust manifolds or both. To reduce vehicle drag due to its trailing vacuum and to the turbulence it causes, an air-collecting scoop is provided at the top of the windshield to receive air of the curtain as it leaves the windshield. The collected air is then ducted to the rear of the vehicle and exhausted into the trailing vacuum to reduce vehicle drag.

  • Patent number: 5548522
    Abstract: A modular wiring system using a plurality of field interface devices modularly selectively interconnected by wire bundles with redundant capacity to form a network of field interface devices each connected to a reference circuit, maintained at near-zero ground through a fluid electrolyte flowing through a grounded electrically-conducting pipe to which each field interface device is connected, is continually controlled by a central microprocessor that monitors electrical load and modifies connections of wires between bundles through switches within each field interface device to optimize load distribution within the system. Electrolyte flowing in conductive pipes is charged as it neutralizes potential differences between the field interface devices. The electrolyte is deposited in a grounded reservoir in which the electrolyte discharges its charge to anodes and cathodes therein in the manner of a battery, thereby extracting energy of the electrolyte before the electrolyte is pumped back into the ground pipes.

  • Patent number: 5542708
    Abstract: A versatile binder for binding leaf materials, including sheets of paper as well as carpet samples, is provided with a bellows between legs of a binding bracket for adjustment in receiving differing thicknesses of materials to be bound. The bellows is actuated with a manual air pump mounted on the binding bracket under a bladder. A torsion spring-biasing binding clamp is further provided to secure the bound materials in place once the bellows have been positioned. An alternative binding clamp is provided in one or more tapered pins on an upper bracket member matching frustum bores in blocks mounted to lower bracket members, frictionally.binding the two members together when the tapered pins are urged into the frustum bores.

  • Patent number: 5507350
    Abstract: A remote fire fighting method provides for remote and early response delivery of solid carbon dioxide in capsules by means of standard artillery guns to cool the fire and displace needed oxygen from the fire, useful for fighting fires difficult to approach such as forest fires as well as fires in developed areas, such as urban multistory buildings. Projectiles of encapsulated solid carbon dioxide are produced and strategically stored refrigerated until a fire occurrence at which time they are launched as a projectile from standard artillery guns in a pattern that surrounds the windward side adjacent and outside the fire followed by a pattern of launched projectiles about one-third of the way into the fire from the leeward side such that carbon dioxide gas from said first and second sets envelopes at least a portion of the fire area and migrates through the fire, chilling it and excluding oxygen for combustion therein to arrest progress of and extinguishing the fire.
