摘要:
A hygroscopic power plant utilizes low salinity liquid (e.g., sea water having a salinity of about 4%) and a source of high salinity liquid (e.g., brine having a salinity of about 38%) for generating electricity. The plant includes a flash chamber to which liquid is supplied and within which water in the liquid is flashed into steam producing more concentrated liquid. A steam turbine is responsive to the steam for generating electricity and producing heat depleted steam. A condenser is provided to which high salinity liquid and the heat depleted steam are supplied for directly contacting the steam with the high salinity liquid whereby the steam condenses on the liquid producing diluted high salinity liquid. A regenerator is provided for evaporating water from the diluted high salinity liquid to produce the high salinity liquid supplied to the condenser. Apparatus is provided for combining the low sea water liquid with the concentrated liquid produced by the flash chamber to form the liquid supplied to the flash chamber.

A solar power station has a heat source in the form of the heat storage layer of a solar pond, a heat sink in the form of the wind-mixed layer of the pond covering the halocline interposed between the heat storage layer and the wind-mixed layer, and a power plant associated therewith. The power plant includes a boiler responsive to water from the heat storage layer for vaporizing a working fluid, a prime mover for producing work by extracting heat from vaporized working fluid, and a condenser cooled by water from a cooling pond connected to the solar pond such that only water in the wind-mixed layer is exchanged with the cooling pond. The wind-mixed layer serves to dissipate heat from the condenser and the volume of water in the cooling pond increase the heat absorption capacity of the heat sink.

Weather in the vicinity of a land mass such as a continental arid zone near, and usually eastward of a body of water is modified by preferably propelling a ship pulling a submerged body having plurality of vertically displaced foils having an angle of attack that effects an upward displacement to the water in response to the surface displacement of the ship. The upward displacement of the water moves cooler sub-surface water toward the surface thereby cooling the surface water and reducing its heat loss in the summer. As a result, the heat capacity of the water is increased and additional heat will be stored in the water as a consequence of the greater absorption of solar radiation thereby increasing winter storms and the amount of rainfall over the land mass during the winter.

The weather near a continental arid zone is modified by increasing the heat storage of the seas westwardly of the arid zone during the summer. The heat storage is increased by mixing the relatively warmer surface water with relatively cooler deeper water thereby reducing the surface temperature of the seas during the summer. Cooling the surface of the water will increase the radiant heat flux due to solar radiation and decrease the radiant heat loss from the surface during the summer thus increasing the amount of heat stored in the water an available for evaporation during the winter. Mixing is achieved by pumping water from a lower level in the seas to the upper level. In one embodiment of the invention, normal wave motion provides the mode of power for the pumping operation. In another embodiment, mixing is achieved by a paddle that is operated by wave motion.

A centrifugal heat engine comprises a first member rotatably mounted on a second member. The first member has an annular chamber on its periphery containing a vaporizable working fluid, and a central chamber separated from the annular chamber by a bulkhead. The central chamber contains an operating liquid and an hydraulic turbine mounted on the second member which projects into the central compartment and divides the same into two axially displaced compartments each of which contains operating liquid. The working fluid in the annular chamber is heated and vaporized. A conduit conducts vaporized working fluid in the annular chamber into one of the compartments wherein the vaporized working fluid expands in the operating liquid producing a liquid/gas mixture in the one compartment. Rotation of the first member creates a pressure differential between the two compartments that is related to the rotational speed of the first member and the density distribution of the fluids in the two compartments. The turbine contains a structure in cooperation with the first member for effecting a fluid path for the operating fluid between the two compartments such that rotation is imparted to the first member.

Power is produced by a power plant using a salt-water solar pond comprising an upper wind-mixed layer, a halocline and a lower convective heat storage layer. The power plant includes a heat engine for utilizing heat present in the heat storage layer of the solar pond and a condenser, which preferably is cooled by liquid droplets. In accordance with a specific embodiment of the invention the power plant is positioned within the solar pond and a flash evaporator is used in the heat engine to produce steam which is supplied to a turbine connected to a generator, the heat depleted steam exiting from the turbine and being cooled by liquid droplets in a direct-contact condenser. The size of the droplets is selected such that the heat extracted in the condenser penetrates the majority of the liquid content of most of the droplets.

The wind-mixed layer of a salt-water solar pond is dynamically stabilized against wind by creating a two-layer flow regime in the wind-mixed layer. Lighter less dense water flows in one direction adjacent the surface of the pond and heavier, more dense water flows in the opposite direction beneath the lighter water. The two-layer flow regime can be created by selectively connecting the wind-mixed layer to a source of brine whose density exceeds the average density of water in the wind-mixed layer. Alternatively, the two-layer flow regime is created by selectively adding fresher water to the surface of the solar pond at the surface thereof to replace evaporation losses.
摘要:
A halocline is maintained in open body of salt water at a depth to which a significant amount of solar radiation penetrates by inducing an upward vertical flow in the body of water sufficient to counter wind-mixing and molecular diffusion thereby establishing an ascending or rising solar lake. The upward flow is induced by injecting into the body of water a concentrate with a density greater than the density of liquid at the lower end of the halocline, the concentrate being formed by evaporating liquid drawn from the surface of the body of water. The halocline suppresses convention currents and allows solar radiation to heat the halocline as well as a layer of liquid therebelow to temperatures significantly higher than the surface temperature. Heat for useful work can be extracted from the heat storage layer beneath the halocline.In a modification, the linearity of the halocline and its consequent stability are controlled by inducing a downward vertical flow simultaneously with and equal to the upward flow thereby establishing what is termed a standing solar lake. The downward flow is induced by flash evaporating liquid drawn from the heat storage layer.
