摘要:
A window/light shelf system enhances the daylight illumination with no glare. The air space between the double panes of the window is enlarged, and a mini blind-like, light reflective or absorbing, low transparent glass plates unit is integrated in the middle to control the daylighting and to eliminate the glare. With the light reflective unit open and closed per solar/climate conditions, the system serves as a window, a light shelf with no glare, a solar heating source in the winter, and a solar heat reflector in the summer.

A water-heating solar parabolic collecting and concentrating apparatus comprises a pair of inclined parabolic reflectors positioned side by side on a rotary framework with upwardly extending water-heating tubes positioned along the focal lines of the respective reflectors. The tubes are split longitudinally into forward and reverse flow water passages by vanes which also provide heat transfer enhancing fins projecting diametrically from the tubes. Inlet and outlet hoses from the respective tubes extend through a turntable base forming part of the framework on which the collectors are mounted, for rotational sun-tracking under the power of a timer-controlled electric motor.

A condenser of solar energy on a moving structure, with east-west solar tracking and a modular liquid lens, the former consisting of a system capable of concentrating the solar energy by the incorporation of one or several modular liquid lenses, and the latter comprised by the connection of different transparent lenticular recipients, capacitated for installation on a metallic structure of spherical or cylindrical shape which, by means of the action of a divergent lens and a liquid prism transmits the heat to the fluid in a primary circuit which by means of a heat exchanger provides the temperature necessary for the different energy uses.
摘要:
A combined solar-wind energy conversion system in which the combined effects of solar and wind energy are utilized in raising water from a lower to an upper water storage tank to increase its potential energy for generation of electricity. Incoming solar energy heats water to form steam which is temporarily stored. The stored steam is vented to one of first and second steam storage tanks from which it is coupled to first and second water pumping tanks. When the water enters one of the water pumping tanks, it forces the water temporarily stored therein to flow upwards the first steam storage tank. As soon as the water pumping tank is emptied, the steam condenses forming a partial vacuum in the tank. The vacuum causes water to be drawn from the lower water storage tank into the corresponding water pumping tank and the process repeated. The second water pumping tank is filled while the first water storage tank is emptied. Water flowing from the first water storage tank turns an electrical generator. Wind energy is also used to raise water from the second water storage tank to the first water storage tank to increase the available energy. When excess electrical energy is available, it is used to electrolyze water into hydrogen and oxygen which are stored for later burning during periods when insufficient wind and solar energy are available.

An extensive photovoltaic array for generating electric power from solar radiation as in a power plant includes an extensive unitary structural grid having substantial extent in both x and y directions and supported on a pedestal. The unitary structural grid is defined by a multiplicity of structural members connected to one another at angles and defining spaces therebetween. The structural grid has a depth sufficient to provide structural rigidity to the photovoltaic array. A large multiplicity of lens assemblies, each including at least one lens, is directly supported by and in spaces defined between structural members of the unitary structural grid. The lens assemblies close the upper side of the unitary structural grid. All other sides of the unitary structural grid are also closed. A plurality of solar cells are located within spaces defined between structural members of the structural grid and positioned to receive solar radiation that passes through respective lenses of the lens assemblies. The lens assemblies and the structural members of the structural grid have an integrated relationship.
摘要:
The invention is a solar-powered, Rankine cycle, two fluid, engine useable for many functions, especially for pumping liquids from the ground such as water or oil in remote locations. The engine driven by heat energy collected in standard collectors or in solar ponds utilizes a heated fluid such as water to transfer the heat from the collectors to a tank where a volatile working medium is transformed into a pressurized vapor. The heated working medium is then fed to a double acting cylinder where work is extracted from the working medium. The engine is a rather slow moving engine, with the valving controlled by electric switches which are driven by storage batteries. The storage batteries are continuously charged by solar energy. If the source of energy is heat collected by standard collectors, a tracking device for the collectors, also driven by solar power, is incorporated in order to attain high collection efficiencies. The engine is used to drive either mechanical or hydraulic pumping devices. The invention is especially suited to remote locations, and for those purposes where constant vigil of the engine is impractical. The engine and the accessories are self sufficient in that they require little or no maintenance, and are not dependent on a fuel or electricity supply.
摘要:
Solar energy system incorporating a dirigible motor-driven collector and an electronic sensor for turning the collector to follow the sun. The collector is turned progressively during the day to occupy successive positions during predetermined time periods in which it collects solar energy most efficiently, at the end of the day automatically returning the solar collector to its initial, morning position. The system is controlled by an arrangement which is composed largely of a novel combination of commercially available units, thereby cutting its cost and increasing its reliability.

The invention introduces a coplanar rotational method of tracking the sun for use in a focusing solar collector that comprises of one or more linear focusing means such as cylindrical parabolic mirrors and linear lenses. Such a solar collector has one or more linear focal regions. It is particularly advantageous to use this tracking method in a large panel collector having multitude of linear focusing means. A plane parallel to the linear focal region or regions and perpendicular to the front plane of a solar collector is denoted as a focal plane. In applying the tracking method to the solar collector, the collector is rotated around an axis perpendicular to the front plane so that the sun'rays become parallel to the focal plane. The front plane remains substantially on the same plane during the tracking operation.
摘要:
An application and a method for receiving and transmitting thermal solar energy. A collector of solar energy reflects solar energy to a heat pipe which transmits vapor produced therein to a condenser to release and utilize the thermal energy carried by the vapor either to perform heating functions or to be dissipated as the vapor is condensed.
