  • Patent number: 3992885
    Abstract: A drive arrangement for the auxiliary aggregates of a motor vehicle equipped with an internal combustion engine which includes an electrical power supply system with a generator and a battery; only those auxiliary aggregates which have a power requirement dependent on the rotational speeds are thereby driven from the internal combustion engine as heretofore whereas all auxiliary aggregates which have a power requirement independent of the rotational speed are driven in common from an electrical motor operating at substantially constant rotational speed and fed from the electrical power supply system; a thermionic converter operable by means of the fuel of the motor vehicle is thereby provided as generator.

  • Patent number: 3991563
    Abstract: The housing of the power plant defines a chamber at a level below the surface of a surrounding body of water; and also a series of penstocks which open into the water at points between the level of the chamber and the surface of the water, and which discharge into the chamber. The hydroelectric power generating means in the plant include turbines in the penstocks, and means for discharging the tailwater from the respective turbines including nipples on the housing which communicate with the chamber and open into the body of water at levels below that of the chamber.

  • Patent number: 3979597
    Abstract: A solar energy powerplant has a group of tall, vertical towers open at both ends and containing a plurality of wind-powered impellers mounted in vertically spaced locations within each tower, such that thermal updrafts in the tower drives the impellers. Vertically spaced, radially projecting heating chambers are mounted externally on each tower and each chamber has an air inlet to admit ambient air and an air outlet into the tower for heated air. The heated air entering the tower for the solar heating chambers forms an updraft for powering the impellers. The heating chambers also contain heat exchange tubes which connect with an insulated water reservoir in the base for the towers.

  • Patent number: 3978344
    Abstract: A process for generating energy by utilizing the osmotic pressure resulting when two liquids having different chemical potentials are each placed in contact with opposite sides of the same semipermeable membrane. The process is particularly applicable to the production of energy from the system sea water/fresh water. The sea water is in the form of an enclosed body having an outlet orifice in communication therewith. The fresh water passes through the semipermeable membrane causing the osmotic pressure which ejects a stream of salt water through the outlet orifice.

  • Patent number: 3970917
    Abstract: A system is disclosed for storing electrical energy and for converting DC power to AC power. The system includes a very large flywheel which is mounted in an evacuated housing and is driven by a plurality of wheels powered by DC electric motors which receive current from an input power source. An independent plurality of wheels coupled to AC generators selectively engage the rotating flywheel to withdraw energy from the rotating mass of the flywheel in the form of alternating current. Control systems are provided for adjusting the radial position of the drive and output wheels in dependence upon the speed of the flywheel. Additional control systems are provided to change the number of driving motors or output generators in contact with the flywheel depending upon the input power available or output power required.

  • Patent number: 3965362
    Abstract: Waste matter is incinerated utilizing pure oxygen in addition to the oxygen obtainable through ambient air thereby raising the temperature in the incinerator to an amount of the order of 500.degree.F greater than the incinerator temperature normally encountered when only ambient air is introduced into the incinerator. The incinerator combustion gases are passed into a waste heat boiler to generate steam for operating a steam turbine incorporating an electric generator. A portion of the electric power developed by the generator is utilized in conjunction with an electrolytic cell structure to perform an electrolysis operation upon water to separate the water into its constituent parts (hydrogen and oxygen). A portion of the hydrogen is utilized in the burner plenum of the waste heat boiler to increase the temperature of the incineration combustion gases.

  • Patent number: 3965363
    Abstract: Taking advantage of numerous sources of fueless energy such as the heats of volcanoes, hot springs, active and inactive oil and natural gas wells, geothermal heats and other natural steam power, some of these energy sources intermittent, and others continuous, are here combined to provide a steady flow of continuous fueless power for stationary or movable power plant use. It saves fossil fuels for uses far more important than their combustion, and does not pollute our human environment.

  • Patent number: 3943370
    Abstract: A friction-drive electricity generating method and equipment utilizing the driving wheel of motor cars, where, in order to make it possible to generate electricity efficiently for a long period by using the engine power of motor cars, a base plate with a jack attached is fixed to one of driving wheels of the motor car in such a manner that it may be held between them and then a dymamo is installed, removably and tilting freely, on the said base plate so that the driving wheel may be lifted up with the said jack and so that electricity may be generated by pressing the dynamo shaft against the driving wheel while it is being revolved by the motor car engine.

  • Patent number: 3936652
    Abstract: A heat source heats air which rises in a duct having at least a one hundred meter vertical rise. Cold air enters the bottom of the duct through one or more horizontal passages containing vanes driven by moving air as a power source. The heat source may be a heat exchanger connected to an atomic reactor, a fossil fuel plant, a solar collector, or a geothermal heat supply. The heat exchanger may be located in the duct or in the one or more horizontal passages. In some applications, solar energy may directly heat the duct or a grid therein to cause an air flow.
