摘要： A unique method and ternary cycle process that captures heat from low temperature sources currently considered not commercially usable to produce electricity and desalinate water. In one cycle a novel flash tower operating at vacuum pressure causes a fraction of low temperature water to flash into steam. The steam passes to an indirect heat exchanger with a circulating refrigerating agent such as CO2, which condenses the steam on its outside surfaces to produce desalinated water product. The steam heat of condensation vaporizes the refrigerating agent, which is part of a binary refrigerate cycle that uniquely conditions it for turbine expansion to produce electricity in a connected electric generator.

摘要： A solar plant including a solar field for production of steam, a turbine using steam, and an excess steam storage and draw off system. The system includes a latent heat thermal storage module and a liquid displacement thermal storage module including a liquid volume and a steam blanket. The modules are connected together so that the steam produced passes through the steam blanket before passing through the latent heat module, condensing, to be injected in the liquid volume, the lower part of the liquid volume being connected to the solar field and to an outlet of the turbine to let in or return cold liquid. The liquid volume acts as a liquid displacement reservoir.

摘要： The Power Generating Dome provides a structure that creates shelter, insulating the contents or individuals inside from the elements, while also generating electrical power. The electrical power is generated using one or more methods, the methods being interchangeable and varying depending upon the location of the Power Generating Dome, the time of day, and the seasons.The first and primary method of power generation is to harness the energy created by rising air. The rising air powers a turbine, and the turbine generates electricity.The second method of power generation is an omni-directional horizontal wind turbine, powered by wind blowing past the Power Generating Dome.The third method of power generation is a parabolic mirror used to turn water to steam.

摘要： In a system where the thermal energy of a geothermal fluid is applied to an ORC system, the energy is enhanced by the use of solar energy to thereby increase the temperature of the fluid being applied by the ORC system. A single heat exchanger version provides for direct heat exchange relationship with the geothermal and solar fluids, whereas a two heat exchanger version provides for each of the geothermal and solar fluids to be in heat exchange relationship with the working medium of the ORC system. Control features are provided to selectively balance the various fluid flows in the system.

摘要： An auxiliary steam supply system in a solar power plant includes a solar receiver having a superheater section, a turbine, a steam circuit, a thermal energy storage arrangement and an auxiliary steam circuit. The thermal energy storage arrangement, including a thermal energy storage medium, is configured for the steam circuit to receive a portion of the steam to heat the thermal energy storage medium. The thermal energy storage arrangement may receive the steam from any location across the superheater section. Moreover, the auxiliary steam circuit generating auxiliary steam flow, which thermally communicates with the thermal energy storage arrangement to be heated, is introduced to any location across the superheater section. Capacity of the thermal energy storage arrangement may be relatively small as compared to the solar receiver and may be compact for placement on top of a tower.

摘要： Method for conversion of energy, by which a sun energy, or heat energy, or radiation energy is converted in an other form of energy, where the energy in its heat form or in the form of radiation is supplied to a vaporizer of a heat pipe, and this energy is converted in the energy of a working gas of the heat pipe through (as a consequence of) the absorption of this energy by the working liquid of the heat pipe; the energy in its heat form is extracted (conducted away) from the condenser of the heat pipe, and the energy of movement of the gas of the heat pipe is converted in others, not heat forms of energy, in particular into electric energy, where additionally to the capillary or gravitational forces, usually acting in the heat pipe transport zone to recover the heat pipe liquid, an additional energy, in its mechanical or electrical or any other not-heat form, is supplied to the working liquid of the heat pipe, among other possibilities, from outside in respect to the heat pipe, and this additional energy is converted in a mechanical energy of a mechanical movement of this heat pipe working liquid, and at the same time one directs the gas flow from the vaporizer to the condenser through one or several constrictions, where the cross-section area of this constriction or these constrictions in the plane, which one is perpendicular to the direction of the gas flow, is essentially mach less than an average cross-section area of the vaporizer or condenser, which way an effectiveness of energy conversion is increased.
