Abstract
An electric propulsion system for a vehicle having an electric drive motor. A generator supplies electric current to the motor. A dual shaft turbine engine having a compressor and a gasifier coupled with a first shaft and a power turbine, flywheel and generator coupled to a second shaft provide electric current to the electric drive motor. The first and second drive shafts are uncoupled and are allowed to spin independently of one another. Exhaust gases from the gasifier turn the power turbine, thus the turning power turbine turns the generator and flywheel as a unit.
