First claim

What is claimed is:

1. An energy storage device comprising:
multiple bulk superconductor rings;
at least one superconductor wire coil between the multiple bulk superconductor rings, the multiple bulk superconductor rings and the at least one superconductor wire coil interconnected to define a closed geometric shape; and
a spacer between two or more bulk superconductor rings of the multiple bulk superconductor rings, wherein the spacer electrically isolates a first bulk superconductor ring of the multiple bulk superconductor rings from a second bulk superconductor ring of the multiple bulk superconductor rings, and wherein the first bulk superconductor ring is configured to induce a magnetic field in the second bulk superconductor ring.

2. The energy storage device of claim 1 , wherein the multiple bulk superconductor rings and the at least one superconductor wire coil are included in an aircraft or a spacecraft as an energy storage device.

3. The energy storage device of claim 1 , further comprising a plurality of spacers between the multiple bulk superconductor rings.

4. The energy storage device of claim 3 , wherein the second bulk superconductor ring is electrically isolated from a third bulk superconductor ring of the multiple bulk superconductor rings.

5. The energy storage device of claim 1 , further comprising an insulating layer between two or more bulk superconductor rings of the multiple bulk superconductor rings.

6. The energy storage device of claim 1 , wherein the closed geometric shape is a curved shape.

7. The energy storage device of claim 1 , wherein the at least one superconductor wire coil comprises a plurality of superconductor wire coils spaced around the closed geometric shape.

8. The energy storage device of claim 1 , further comprising an electrical interface configured to couple the at least one superconductor wire coil to at least one of a power supply or a load device.

9. The energy storage device of claim 1 , further comprising a particular ring comprising a superconductor material, wherein a first superconductor wire coil of the at least one superconductor wire coil is housed in the particular ring.

10. The energy storage device of claim 1 , wherein a first superconductor wire coil of the at least one superconductor wire coil is configured to induce a magnetic field in each of the multiple bulk superconductor rings.

11. The energy storage device of claim 1 , wherein the multiple bulk superconductor rings are configured to be magnetically linked while a current runs through a first bulk superconductor ring of the multiple bulk superconductor rings.

12. A method of operating an energy storage device, the method comprising:
generating a magnetic field in a region of at least one superconductor wire coil responsive to a charging current applied to the at least one superconductor wire coil;
