Abstract: A device and method for generating electrical energy from hydrogen and oxygen, includes a combustion engine, a heat recovery steam generator connected into the exhaust gas duct of the combustion engine, wherein the heat recovery steam generator has only one pressure stage. An H2—O2 reactor is provided to which steam from the heat recovery steam generator, water, oxygen and hydrogen are fed, such that, in the H2—O2 reactor, a reaction of oxygen and hydrogen forms steam, the water that is introduced is evaporated, additional steam is generated, the resultant superheated steam is fed to a steam turbine, and a generator connected to the steam turbine provides an electric power. High-pressure feed water is injected from the heat recovery steam generator into the H2—O2 reactor via a line to control the reaction in the H2—O2 reactor in a targeted manner and set the steam exit temperature from the H2—O2 reactor.

Abstract: A solar-powered generator captures solar energy and generates steam with the energy. The generator includes a container formed with an inner spherical wall defining an inner chamber and having an inner reflective surface containing photovoltaic cells and an outer spherical wall defining an outer chamber located between the inner and outer spherical walls. The container is formed to allow for sunlight to enter the inner chamber. An inlet port is configured to allow water to enter the outer chamber and an outlet port is configured to allow steam to exit the outer chamber, whereby sunlight entering the inner chamber through the passage bounces off of the inner reflective surface allowing thermal energy to heat the water in the outer chamber to create steam to generate electricity through an external steam turbine. While simultaneously using radiant energy to be absorbed by photovoltaic cells to generate additional electricity.

Abstract: Extra heat in a closed cycle power generation system, such as a reversible closed Brayton cycle system, may be dissipated between discharge and charge cycles. An extra cooling heat exchanger may be added on the discharge cycle and disposed between a cold side heat exchanger and a compressor inlet. Additionally or alternatively, a cold thermal storage medium passing through the cold side heat exchanger may be allowed to heat up to a higher temperature during the discharge cycle than is needed on input to the charge cycle and the excess heat then dissipated to the atmosphere.
