Title:
【発明の名称】エネルギー貯蔵装置
Document Type and Number:
Japanese Patent JP2992578
Kind Code:
B2
Abstract:
A rotary member (2) is continually held suspended in the space by a strong pinning force (fishing effect) of high temperature oxide superconductors (1) under superconductive state. The magnetic field of the magnets (3) on thus suspended rotary member (2) is distributed concentrically about the center of the pinning force, so that the rotary member can be continually rotated in a non-contact state while being lifted off the high temperature oxide superconductors (1). Thus, by utilizing the external energy via an input/output device (10,11), the theory member (2) is rotated in a vacuum tank (6) under highly vacuum state and is held continually rotating for an extended period of time. By taking out the kinetic energy of rotary member via the input/output device, the stored energy can be taken outside.
