Abstract: A closed-cycle cryogenic engine is provided for propelling vehicles or generating electricity at high power densities without consuming any working fluid. The engine comprises a working fluid having a high specific heat that remains in a gaseous phase. The high temperature heat reservoir is the natural environment and the low temperature heat reservoir is created artificially by evaporating water. By isothermally compressing the working fluid at low temperature by absorbing the heat of compression by evaporating water, it is possible to extract a large amount of natural heat energy from the environment and convert a large fraction of it into net output work. Since the latent heat of evaporating water is very high, very little water is consumed which represents the engine's only fuel.

Abstract: Method of operating a solar thermoelectric power plant that allows operation of high-, medium- and low-pressure superheating turbines with both superheated steam and saturated steam. The plant includes energy storage in high-pressure liquid tanks. The method described allows the direct introduction of saturated steam into a superheated steam turbine. This steam may receive an intermediate reheating between the high-pressure turbine and the low- and medium-pressure turbines to achieve conditions of superheated steam. The mode of operation proposed in the invention facilitates the operation of the plant in periods without sunshine (during transient periods, such as passing clouds or night time) or during discharge of accumulators (saturated liquid tanks at high-pressure).

Abstract: Method for the natural-draught cooling of a high-concentration thermoelectric solar plant that includes a central receiver or tower with a heliostat field, wherein the tower is used as a natural-draught cooling tower. The steam originating from the turbine will be made to circulate through a series of condensers located at the base of the tower, where said condensers condense the steam therein and discharge the condensation heat to the atmosphere. The fluid responsible for this heat exchange is the air at ambient temperature at the base of the tower. Once condensed, the steam is pumped back towards the receiver so that it can be re-used as a heat-transfer fluid. The cooling air travels up through the tower and exits through the highest part thereof. The plant can be used to reduce not only its own electricity consumption, but also water consumption.

Abstract: Thermal energy can be stored in a fluid-based thermal storage system for later use. The stored thermal energy may be derived from steam generated using insolation in a steam-based solar power system. The thermal storage system can store energy when insolation is generally available. Alternatively or additionally, the thermal energy may be derived from electricity from the electrical grid. For example, the thermal energy can store energy when the electrical grid has excess electricity available for storage. At a later time, the energy stored in the thermal storage system can be released to heat pressurized water or steam in addition to or in place of steam generated by the insolation. For example, the stored thermal energy may be used in preheating the solar power system during startup, in supplementing steam output of the solar power system, or to replace steam generation during low insolation periods.

Abstract: The invention relates to energy conversion and generation systems, and more specifically, to a system and method of generating and converting energy by way of a pressure differential in a working fluid. A Pressure Power System is described comprising a cold sub-system, a warm sub-system, a work extraction system, and a hydraulic pump arranged in a closed loop. The cold sub-system and the warm sub-system are respectively maintained at lower and higher temperatures relative to one another, so that a Working Fluid circulated through the closed loop by the pump, will have different equilibrium vapor pressures in the two sub-systems. The different respective state functions of the Working Fluid results in two different levels of elastic potential energy, and subsequently, a pressure differential between the two sub-systems. A work extraction system is positioned between the two sub-systems to convert the elastic potential energy/pressure differential into useful kinetic energy.

Abstract: The present invention in several embodiments is an apparatus for producing potable distilled water and solar-thermal energy, as co-products of the generation of steam from sea water by concentrated solar radiation. This apparatus would be comprised of an array an Fresnel lenses of the same or substantially the same focal length which preferably each have an area of approximately 1 square meter, which are oriented in the appropriate 3-dimensional plane in relation to the sun to collect the maximum amount of solar energy over the area of the lens; the lens array would follow or “track” the sun across the horizon in two dimensions. The lens array would focus the collected and concentrated solar radiation in one discrete area of a boiling of several square centimeters, in order to produce steam which is then used to create power and is condensed to provide distilled water.
