  • Method of storing electric power
    Patent number: 4189925
    Abstract: A method for storing electric power and later utilizing the stored power is described which includes the steps of converting the electric power to chemical energy of molecular hydrogen, reacting the hydrogen with a source of carbon to produce a hydrocarbon compound such as methane or methanol, storing the hydrocarbon compound, and then supplying the hydrocarbon compound as fuel to a generator which operates to generate electric power. In one embodiment of the invention the hydrocarbon fuel is used to heat stored compressed air which is in turn used to drive a turbogenerator.

  • Remote data readout system for transmitting digital data over existing electrical power lines
    Patent number: 4040046
    Abstract: A system for providing remote readout of a plurality of groups of data indicating devices including a control unit for each group of data indicating devices for receiving interrogate data signals transmitted over a communication line or RF signal link from an interrogate unit at a central location to the locations of the control units, and for transmitting the interrogate data to transponders associated with the indicating devices over existing electrical power lines to which the control unit and transponders are connected via existing electrical outlets. The transponders are responsive to the interrogate data to generate reply data representing the reading of an associated indicating device for transmission over the electrical power line to the control unit which effects the transmission of the reply data to the central location.
