<p>A flywheel (10) having superconductor bearings (110) has a lower drag to lift ratio that translates to an improvement of a factor of ten in the rotational decay rate. The lower drag results from the lower dissipation of melt-processed YBCO, improved uniformity of the permanent magnet portion (120) of the bearings (110), operation in a different range of vacuum pressure from that taught by the art, and greater separation distance from the rotating members of conductive materials.</p> |
