摘要： This invention is a trough solar collector that uses the principles of high leverage in order to produce a lightweight, inexpensive thermal solar collector. The parabolic reflectors are held in proper shape by rigid ribs that are spaced apart along the length of the collector. The structure of the trough is held rigid by a unique sun-tracking system that not only guides a long trough row to point it toward the sun, but also maintains the whole length of the row in rigid configuration. Small-diameter cables are wrapped around a rotatable pipe that extends along the row. The cables extend around circular arches attached to the parabolic ribs that provide high leverage for rotating the troughs. Since the arches rotate in unison, the long trough row is maintained in rotational rigidity. Rather than having heavy concrete foundations and heavy structures to support the troughs, lightweight support posts are placed into the ground, and guy wires maintain the position of the posts.

摘要： A means is provided to produce fresh water from seawater on both the boiler side and the condenser side of an OTEC power plant. Part of the warm ocean surface water is evaporated, and its vapor transfers heat to the working-fluid boiler as the vapor condenses. The condensation of the vapor provides fresh water. On the condenser side, the condensation of the working-fluid vapor from the turbine in the condenser releases heat that evaporates seawater that runs down the outside of the condenser surfaces. The vapor from the seawater is condensed by a heat exchanger that uses input from colder seawater. As the cold seawater accepts heat from the condensing vapor, it becomes slightly warmer and provides the source of seawater that accepts heat from the condenser. The condensing vapor on the heat exchanger becomes fresh water that is drawn out as potable water. To provide additional fresh water, a multi-stage desalination unit uses the warm water discharge and the cold-water discharge from the OTEC plant to provide a temperature gradient that causes evaporation and condensation in each stage of the unit.

摘要： A motor, expander, compressor, or hydraulic device is formed with an oscillating rotating piston comprising a cylinder having an axis of rotation and end surfaces and defining an oscillating compression volume and an expansion volume. An axial sealing member separates the compression volume and the expansion volume, and seal members seal the end surfaces of the piston. Valves operate to close the compression volume and open the expansion volume at each oscillation of the piston. Means are provided for reversing the rotation of the cylinder at the end of a compression cycle of the piston. One or more pistons may be provided that contact other pistons along axial surfaces to form axial seal surfaces with rolling contacts that reduce friction energy losses.

摘要： This invention is a water producer that extracts water from the air. One embodiment of the invention adiabatically compresses and heats the air. The heated air is cooled through a counter-flow heat exchanger so that it becomes supersaturated and water condenses. The air is then cooled further and passed back through the heat exchanger to recover its former heat. It then passes through an adiabatic expander to recover energy. A second embodiment utilizes a unique isothermal compressor/expander to compress the humid air isothermally so that the air becomes supersaturated with water, and the water condenses. The air is then cooled to remove the heat of condensation of the water and returned to the isothermal compressor/expander to recover energy. A third embodiment draws in humid air through a counter-flow heat exchanger to cool it down below its dew point so that water is collected. The air is then cooled adiabatically and passed back through the counter-flow heat exchanger and on to a compressor, which compresses the air back to ambient pressure and pushes the air out. These embodiments can be used to desalinate seawater, brackish water, or desiccant aqueous solutions by having a humidifier evaporate water from the liquids to make the input air to the water producer very humid.

摘要： A solar energy collection system harvests solar energy from large open areas. A length of flexible solar collector is provided for unrolling along a supporting surface. A first layer of the solar collector is an uninsulated base panel for directly contacting the ground or other supporting structure. A plurality of parallel conduits are sealed along the length of the flexible base panel and have a high light absorption and a low infrared emission for containing a flowing liquid to be heated by solar energy from the sun. A length of a covering material is placed parallel to the base panel and between the parallel conduits and the sun and sealed to the base panel for containing a low pressure fluid to reduce heat loss from the flowing liquid and to inflate the structure formed by the ground cover and covering material. Heated fluid from the parallel conduits is collected in a header for delivery to a power generating system. The heated liquid is passed through a boiler for boiling a fluid with a low boiling point, such as a refrigerant, and the vapor can then be used in a conventional power plant for generating output energy. In one embodiment, the power plant condenser is cooled by the evaporation of water sprayed into cooling air adjacent the condenser.

摘要： The present invention identifies several configurations of conducting elements capable of storing extremely high magnetic fields for the purpose of energy storage or for other uses, wherein forces experienced by the conducting elements and the magnetic field pollution produced at locations away from the configuration are both significantly reduced over those which are present as a result of the generation of such high fields by currently proposed techniques. It is anticipated that the use of superconducting materials will both permit the attainment of such high fields and further permit such fields to be generated with vastly improved efficiency.
