Power Coil

Also known as accumulators, devices for storing energy in the magnetic fields of a superconducing coil.

Manufactured in different sizes, power coils resemble a ring or disk of EM shielding enclosing a core of room-temperature superconductor. The purpose of this casing is twofold: to hold the superconductor together against the outward force of its magnetic field trying to blow it apart, and contain the results of any failures.

Because superconductors have zero resistance to electrical currents, once charged the stored energy will for all practical purposes remain forever as long as the coil is not placed under load. If the coil loses superconductivity (such as though excessive heating) the stored energy will dissipate as heat, melting the coil and possibly causing an explosion.
