Abstract
A flywheel assembly used for mobile energy storage incorporates a molecular pump and an internal chamber containing molecular sieves. The molecular pump shares the shaft, bearings, and motor of the flywheel rotor, and maintains the high vacuum desired in the vicinity of the flywheel rotor. The gases which evolve from the rotor during its operational life are pumped into the chamber containing the molecular sieves where they are adsorbed.
