Abstract
An improved gas-electric power delivery system is provided. The invention provides an array of internal combustion engine-powered electric generators and an array of electric drive motors wherein each electric drive motor connects to a common shaft. The common shaft of the electric drive motor array connects to a mechanical load of varying power demand. The electric drive motors draw power from a battery in response to demands on the motors by the varying power demands of the external load. The array of electric generators charges the battery and each such generator turns on and off, as needed, to maintain the battery charge in response to demands on the battery by the electric drive motor array. Each electric motor connected to a common shaft in the electric motor array also turns on and off, as needed, to meet the varying power demands of the external load.
