Methods for producing bearing surfaces
First Claim
1. In a system comprising:
- a shaft which defines an axis of rotation; and
a body adapted to rotate around said axis wherein;
said body comprises at least one continuous surface which faces toward the axis; and
a portion of said body is disposed between said continuous surface and said shaft;
a process for producing a bearing surface, comprising the steps of;
placing a liquid proximate the continuous surface;
rotating the body around the axis such that the liquid forms a substantially uniform layer in contact with the continuous surface; and
positioning a member opposite the bearing surface.

Abstract
Flywheel-based energy storage devices are provided along with methods for their use and fabrication. The devices have the capacity to store electric energy as kinetic energy and to generate electric energy from the stored kinetic energy. Preferred devices comprise a pair of counter-rotating anisotropic flywheels which are designed to rapidly rotate within an evacuated housing. The flywheels comprise a lightweight hub and a circumferentially-wound fiber rim. The hub and rim are fabricated from materials having high tensile strength and are connected with system of novel tube assemblies positioned around the hub parallel to the axis of rotation, The flywheel are principally supported by magnetic bearings and are further stabilized during rotation by a self-restoring liquid bearing system.
