Abstract:
A power plant includes a high temperature fuel cell (6), a volume expansion heat engine (11) producing mechanical energy, and a combustion chamber (9) coupled to receive from said fuel cell at least a portion of unconsumed fuel and apply high pressure combusted gases to the engine. A reformer (3) can feed fuel to said fuel cell. A distributor (8) distributes fuel cell exhaust fuel selectively to the reformer and the combustion chamber and varies the ratio of exhaust fuel fed to the reformer and combustion chamber in accordance with predetermined power desired from said fuel cell and engine.
Abstract:
In a general aspect, a system can include a reactor for combusting fuel and producing high-temperature, high-pressure liquid as a byproduct, and at least one vessel defining a cavity to be partially filled with water, with an air pocket within the cavity above the water. The system can further include respective valves to control admission of liquid from the reactor into the air pocket when the air pocket has a pressure lower than an operating pressure of the reactor, and to control emission of the water from the at least one vessel through of the vessel after the water in the at least one vessel has been pressurized by the liquid from the reactor. The system can also include a hydroelectric drive system for receiving water emitted from the cavity, and for converting energy in the received water into electrical energy.
Abstract:
This patent discloses three improvements in thrust vectoring ignition chamber engine described in my indian patent 201821027867 which uses multipurpose double action scotch yoke actuator. First is substituting bilaterally operated bipartitioned slot with quad-laterally operated (quad-partitioned) H-slot in scotch yoke actuator. Second is employing multiple slots instead of single slot in the scotch yoke actuator in conjunction with appropriate modification in the operation mechanism. Third is making arrangement in the scotch yoke operation mechanism which can allow mounting of crank farther from cam gear mounted on ignition chamber without increasing the size of cam follower gear. This patent discloses four models implementing above mentioned improvements. These improvements overcome drawbacks like sideward thrust, wear due to friction, etc. prevalent in conventional scotch yoke actuator.
Abstract:
This patent discloses thrust vectoring ignition chamber engine in which ignition chamber is an annular cylinder having nozzles mounted such that during fuel suction phase they are sealed and during ignition of fuel they are unsealed so that hot jets of ignited fuel escaping through nozzles cause coupled rotatory motion on the ignition chamber. Engine uses specially designed dwell barrel cam mechanism for two phase suction and compression of fuel which facilitates the separation of fuel valve from ignition chamber. Flywheel mounted on extension of ignition chamber functions as output of the engine. Timing of electrically controlled nozzle seal and fuel valve can be adjusted so that each half rotation of flywheel completes three phases namely fuel/air suction, compression and combustion, instead of two rotations as required in engine according to prior art. This engine can give improved power boost by firing for every half revolution.

This patent discloses thrust vectoring ignition chamber engine. Thrust vectoring ignition chamber used in this engine is an annular cylinder having nozzles mounted in a way such that during fuel suction phase they are sealed and during ignition of fuel they are unsealed so that hot jets of ignited fuel escaping through nozzles cause coupled rotatory motion on the ignition chamber. Engine uses specially designed dwell barrel cam mechanism for suction and compression of fuel. Flywheel mounted on extension of ignition chamber functions as output of the engine. Each half rotation of flywheel completes three phases namely fuel/air suction, compression and combustion. Thus this engine fires for every half revolution and therefore can give improved power boost.

Abstract:
Fuel mixed in water is combusted in a reactor having an internal operating pressure and temperature greater than 3200 psi and greater than 374°C, where the combustion of the fuel is exothermic. Air and fuel are pressurized for introduction into the reactor to a pressure greater than the internal operating pressure using energy generated from the combustion of the fuel, and the pressurized air and the pressurized fuel are injected into the reactor. Pressurized water from the reactor is injected into a drive water column that is partially filled with water to increase a pressure of the drive water column, and water at a temperature less than 100°C is injected into the reactor to replace water from the reactor that is injected into the drive water column. Pressurized water from the drive water column is used to drive a hydroelectric drive system to produce electrical power.
