A process of utilizing combustion products from fossil fuels to produce hydro-electric power through a process of allowing such products to displace water from a tank for operating a turbine or pelton wheel. The process allows hydro-electric power to be generated at a greatly increased efficiency. Preferably, two tanks are used to receive combustion products which exert pressure to displace the water. Alternatively, oxygen or air and a fossil fuel such as natural gas are introduced into the tank and combusted therein to generate the combustion products. The process allows existing power plants to generate additional power, and thus greatly increase the overall efficiency of the plant.

Methods for producing hydro-electric power

An energy conversion device comprises an acoustic resonator, a pulse combustion device for creating a standing wave within said resonator, and an electric alternator. The alternator is coupled to the resonator to convert acoustically driven mechanical vibrations into electrical power.

RMS energy conversion

A thermally driven gas resonance device includes a resonance tube (3) which expands in cross-section along its length from one end to the other, a heat source (2) located at the one end of the resonance tube, and an igniter (14) to trigger oscillations in a gas in the tube. The heat source (2) is preferably a pulsed heat source having a repetition frequency corresponding to a resonant frequency of the gas tube (3). The mechanical energy produced in the oscillating gas may be used to operate a pressure swing gas separator by including a bed (16) of molecular sieve material in the other end of the tube (3). Alternatively, the mechanical energy may be used to drive a heat pump (19). In this case a heat sink (21) is located at the other end of the tube (3), a regenerator (20) is also located adjacent the other end, and ports (8) on the side of the regenerator (20) towards the heat source (2) effect heat exchange between the gas in the resonance tube (3) and a source of low grade heat.

a heat pump system selectively operable in cooling and heating modes of operation and having an internal combustion engine prime mover which produces refrigerant vapor compression, and which produces excess heat for rejection, is provided with a first heat exchanger that evaporates compressed refrigerant in the system heating mode of operation, with a second heat exchanger which uses prime mover rejected heat to heat a working fluid, and with a fluid distribution arrangement which is selectively operable to flow the heated working fluid in heat exchange relation to said first heat exchanger also, in the system heating mode of operation to provide a defrost capabilities and to improve heat pumping heating capacity at low ambient temperatures

Gas engine driven heat pump system

An internal combustion hydraulic engine for use in motor vehicles and the like comprises at least one piston having a first piston head and a second piston head; a first or combustion cylinder at least partially surrounding the first piston head for receiving fuel and air; an igniter for inducing combustion of the fuel-air mixture in the first cylinder; and a second or hydraulic cylinder at least partially surrounding the second piston head for receiving fluid such that the action of the combustion of the fuel on the first piston head induces the second piston head to pressurize the fluid in the hydraulic cylinder Preferably, the pressurized fluid communicates through a high pressure tank with a hydraulic motor to convert fluid pressure into rotational power

Internal combustion hydraulic motor and method of operation

A pulse combustion powered apparatus is disclosed for temperature conditioning and pressurizing fluids The alternating periods of positive and negative pressure of the combustion gases of a pulse combustion burner drive a reciprocating compressor and the rejected engine heat is recovered by heat exchange with a primary fluid The compressor may be included in a reversible refrigeration circuit to provide heating and cooling of secondary fluids
