A superconducting magnetic energy storage (SMES) device including a first coil made of superconducting material, a cooling mechanism for cooling the first coil to superconducting temperatures, a second coil inductively coupled to the first coil for inputting emergy to, and/or outputting energy from, the first coil, and a switch for switching the first coil between a superconducting condition and a non-superconducting condition. The first coil is arranged as a closed loop electric circuit having no connecting device mechanically connected to it for inputting or outputting energy. The switch includes a third coil for the application or removal of a magnetic field for switching the first coil between its non-superconducting and superconducting conditions. A method inputs energy to and/or outputs energy from the first coil and a power supply system utilizes the device and method. |
