Radial and axial bearings support an axle shaft attached to a flywheel apparatus to provide rotational support and limit axial movement during rotation of the flywheel. A cage generally surrounding the flywheel and receiving the flywheel within its hollow interior includes a cylindrically shaped side wall positioned adjacent to and concentric with the outside surface of the flywheel to rapidly absorb energy should distortion or shattering of the flywheel occur due to centrifugal force. Means for connecting the flywheel cage to a source of vacuum such as the intake manifold of a thermal engine is utilized to at least partially evacuate the interior of the flywheel cage and thereby increase the ability of the rotating flywheel to store and maintain kinetic energy. A plurality of lubricant passages and reservoirs supply lubricant to the bearings associated with the axle shaft of the flywheel.
