To obtain energy that requires no resources and causes no pollution or noise, as well by making proper use of permanent magnetic force to obtain a power source, and combining this power source with superconductivity.

(1) A large permanent magnet is not manually moved but is moved by moving a flywheel by a foot-operated or an immobilized battery or the like. (2) Then, the low temperature of superconductivity is obtained by a high-performance secondary battery. Thus, only the required amount of permanent energy that requires no resources can be obtained together with power only when needed into the future.
