A charging system with a least one high temperature thermal energy exchange system is provided. The high temperature thermal energy exchange system includes at least one heat exchange chamber with chamber boundaries which surround at least one chamber interior of the heat exchange chamber, wherein the chamber boundaries include at least one inlet opening for guiding in an inflow of at least one heat transfer fluid into the chamber interior and at least one outlet opening for guiding out an outflow of the heat transfer fluid out of the chamber interior. At least one heat storage material is arranged in the heat exchange chamber interior such that a heat exchange flow of the heat transfer fluid through the heat exchange chamber interior causes a heat exchange between the heat storage material and the heat transfer fluid.

A steam reciprocating piston engine that uses a pressurized working fluid to drive first and second pistons in reciprocating power strokes is disclosed. A piston is configured for reciprocating motion within the cylinder and traverses between bottom dead center and top dead center positions. An uppermost stop is reached wherein the working fluid is allowed to escape the cylinder through one or more exhaust ports whereby the fluid travels through a closed loop circuit ultimately directing pressurized fluid back into the cylinder inlet. Momentum causes a spring connected mass to continue upward maintaining the piston above the exhaust port so as to allow escape of the working fluid. Return of the piston and mass is caused by opposite movement of a second piston whereby another stroke is initiated. Power output may be transferred to any suitable system.

A steam turbine 1 includes a turbine body 11 which includes a rotor 5 which is configured to rotate around an axis Ac, and a casing 6 which covers the rotor 5 to form a flow path through which steam flows in an axis Ac direction, together with the rotor 5, a thermal insulation member 12 which is provided to be in contact with an outer surface of the casing 6 in a high-pressure side region 61 out of the high-pressure side region 61 and a low-pressure side region 62 of the steam in the axis Ac direction of the casing 6, and a soundproof cover 13 which covers the low-pressure side region 62 out of the high-pressure side region 61 and the low-pressure side region 62 via a space between the outer surface of the casing 6 and the soundproof cover 13.

System for electrical energy generation from steam comprising at least one stage, each stage including: a steam-driven rotating toroidal ring; a housing comprising a toroidal cavity for containing the rotating toroidal ring, the housing further comprising at least one steam inlet, the housing further comprising a plurality of steam outlets for removing pressurized steam from the channels for at least a second portion of rotation of the rotating toroidal ring within the toroidal cavity; at least one bearing arrangement comprised by or attached to the housing within the toroidal cavity; and at least one pair of electrical coils, each electrical coil located on the outer surface of the housing at locations diagonally opposite from the other coil of each pair across the axis of the minor radius of the toroidal cavity and within the specific region where a time-varying magnetic field will occur as the rotating toroidal ring rotates.

Provided is a solar thermal power generation facility that includes: a compressor; a medium heating heat receiver that receives sunlight and heats a compressed medium from the compressor; a turbine that is driven by the compressed medium heated by the medium heating heat receiver; a power generator that generates electric power by driving of the turbine; and a tower that supports these components. The compressor, the turbine, and the power generator are formed as arranged devices. A plurality of the arranged devices are aligned in a vertical direction.

Thermal energy storage systems are disclosed in this application. Systems of the inventive subject matter are designed to reduce maintenance requirements by sequestering, for example, corrosive fluids that might otherwise damage difficult-to-fix internal components are kept out of those components by introducing a non-corrosive heat transfer fluid to facilitate heat transfer between a thermal energy storage medium (e.g., molten sulfur) and a potentially corrosive working fluid. Thus, the potentially corrosive fluid is kept out of a thermal energy storage tank containing the thermal energy storage medium, which, by design, is difficult to repair when internal components corrode or otherwise require maintenance.

Provided is an energy storage device, including: a first heat exchanger configured to exchange heat between gas and solid particles; a gas supplier configured to supply gas to the first heat exchanger; a heater configured to consume power to heat any one of or both of gas fed from the gas supplier to be supplied to the first heat exchanger and gas present in the first heat exchanger; a solid-gas separator configured to separate gas and solid in a solid-gas mixture discharged from the first heat exchanger; a high-temperature tank and a low-temperature tank each configured to store the solid particles separated by the solid-gas separator; a first heat utilization device configured to use thermal energy of the gas separated by the solid-gas separator; a high-temperature particle supplier configured to supply the solid particles stored in the high-temperature tank to the first heat exchanger; and a low-temperature particle supplier configured to supply the solid particles stored in the low-temperature tank to the first heat exchanger.
