A system for providing a hybrid vehicle with a practical source of auxiliary power. The system includes two electric motor / generators connected to each other in such a fashion so that when one electric motor / generator functions as a motor, the other becomes a generator with their roles being reversed depending on whether the system is in an auxiliary power mode or energy storage mode. Connected to one motor / generator is the vehicle drive train. Connected to the other motor / generator is a pressure energy storage system, which in the energy storage mode converts the force of rotation into pressurized gas for storage in an energy system and delivered in the form of electric current by the one motor / generator, and in the energy delivery mode converts the stored energy of the energy storage system into electric current for delivery to the one motor / generator which is part of the vehicle drive train to provide auxiliary power for practical hybrid vehicles.

An engine power extraction control system controls the main propulsion engines and the electrical machines that are coupled thereto to supply an appropriate amount of aircraft thrust and electrical energy to the aircraft. The engines and electrical machines are also controlled so that the propulsion thrust that is generated is split between the various turbines in the main propulsion engines to maintain an adequate surge margin and to minimize residual thrust generation.

A heat absorbing radiator and a gas turbine engine or a reciprocating piston engine are used to recapture and reconvert wasted heat energies into electric power and finally into hydrogen-deuterium fuel by having the engine's tailpipes submerged in cold compressed air inside the heat absorbing radiator pipes in reverse air flow to further drive the same engine. In order to capture fusion heat energy a hydrogen bomb is detonated in deep ocean to catch the flames by the water and the hot water energizes compressed air inside heat absorbing radiator pipes. In order to produce fusion energy an electric arc is passed thru / across liquid or gaseous deuterium by an electro-plasma torch and by a sparkplug in an internal combustion engine, or by detonating a dynamite inside liquid deuterium. Diamond is produced by placing carbon inside a hydrogen bomb which is then detonated in deepwater. Deuterium fusion flame is used first in smelting glass into large structural sizes before running an engine.

A turbofan exhaust nozzle includes a fan duct defined between a fan nacelle and core engine cowling. The duct includes an arcuate outlet at the trailing edge of the nacelle. A movable flap is disposed in a minor portion of the fan duct, with a remaining major portion of the fan duct having a constant flow area. The flap may be moved between stowed and deployed positions to locally decrease flow area inside the duct for noise attenuation.

A power generation system and method includes a first gas turbine system comprising a first combustion chamber configured to combust a first fuel stream of primarily hydrogen that is substantially free of carbon-based fuels. The first gas turbine system also includes a first compressor configured to supply a first portion of compressed oxidant to the first combustion chamber and a first turbine configured to receive a first discharge from the first combustion chamber and generate a first exhaust and electrical energy. The power generation system further includes a second gas turbine system comprising a second combustion chamber configured to combust a second fuel stream to generate a second discharge. The first compressor of the first gas turbine system is configured to supply a second portion of compressed oxidant to the second combustion chamber. The second turbine system also includes a second turbine configured to receive the second discharge from the second combustion chamber to generate a second exhaust and electrical energy and a second compressor configured to receive the second discharge comprising carbon dioxide. The second compressor is also configured to discharge a recycle stream to the second combustion chamber and a split stream to a separator system adapted to recover carbon dioxide.

An internal combustion engine combusts a first fuel or a second fuel. A method for controlling the engine comprises supplying first fuel to at least one combustion chambers of the internal combustion engine, stopping the supply of the first fuel to the combustion chamber in response to an engine operating condition, and fueling with the second fuel to the at least one combustion chamber after a predetermined period, so as to maintain an engine speed within a predetermined range.

A system for generating electricity includes a generator and an interface. The generator is coupled to the interface and provides data to the interface regarding electricity generation. The interface is coupled to a control node for monitoring and controlling the generator. The control node may be coupled to the generator through a medium such as the internet. In some aspects of the invention, a continuous emissions monitoring system is provided for fossil-fuel based generators to enhance operation and reduce emissions of such generators.

A hybrid clean-energy power-supply framework integrates a fuel cell, solar cell, and wind energy, applies a max power tracking rule, raises the output power of a solar cell and wind energy to supply a power load and transfer the surplus electrical energy to a water-electrolyzing apparatus for producing hydrogen and oxygen, and provides a fuel for a fuel cell power generating system. Furthermore, the present invention utilizes features of each clean-energy power generating system, depends on the powerful calculation capacity of a central processing unit to monitor and dispatch each power generation and supply system, and thus ensures the reliability of supply power and reduces the power generation cost. Such a framework can selectively grid-connect with the utility power or run as a stand-alone power supply system and has a mechanism for preventing the island effect.

A hybrid-vehicle drive unit supports a motor-generator with high precision, improving the efficiency of the motor-generator, and reducing the size of the motor-generator, independent of any influence of centering precision of the crank shaft and of deformation of the torque converter. According to the invention, a motor housing is disposed between a converter housing and an internal combustion engine, and a bearing is fitted to a lateral wall provided in a front portion of the motor housing. Rotor supporting members are independently supported by the bearing. Eccentric rotation of the crank shaft resulting from explosive vibrations of the engine is counteracted by two flex plates. Owing to a predetermined clearance, one of the rotor supporting members as a separate component is free from the influence of deformation of the torque converter.

A high efficiency combined cycle internal combustion and steam engine includes a cylinder and a piston with an internal combustion chamber outward of the piston, a fixed cylinder cap and a steam expansion chamber inside the piston. The cylinder cap can be heated to reduce condensation of steam entering from a steam generator fired by waste combustion heat. Following exhaust, residual steam can be recompressed prior to admitting the next charge of steam. A wrist pin connected to an inner end of the piston skirt inwardly of the cylinder cap is coupled to a connecting rod secured to a crankshaft. One valve or a pair of steam inlet valves are connected to communicate in series within the cylinder cap inside the piston. The steam mass admitted is regulated to reduce fuel consumption. Coolant can be superheated in the combustion exhaust manifold.
