An analytical study indicated that a flywheel-only propulsion system could satisfy the performance requirements specified by the Office of Air Programs, Environmental Protection Agency, for a city bus, and that flywheel/heat engine hybrids could meet the requirements for cars, vans, and buses. In all cases substantial emission-free ranges could be achieved with hybrid systems by using the engine only periodically (at constant load) to recharge a large, high-energy flywheel. Experiments verified the principle of the 'superflywheel' by spin tests of unidirectional materials in rod or bar rotor configurations. (Author)
