Title: Rotor ring for inertial energy storage rotor

Abstract: An improved rotor ring for use in an inertial energy storage rotor, the rotor being defined by a plurality of independent, concentric rotor rings rotatable about a vertical axis. The improved rotor ring includes a cylindrical body portion, fabricated from a fiber composite, and an unreinforced resinous face member attached to one or both of the opposing end faces of the ring. The resinous face member includes a number of radially oriented grooves which are adapted to accept clamps and other elements used to assemble and hold together the rotor rings.
