Superconductor Fiber

The ability of superconductor materials to conduct electricity with nearly zero resistivity is well known, but limitations such as the requirement for extremely low operation temperatures has limited the realization of this potential. The "superconducting optical fiber" takes advantage of pre-existing technologies and manufacturing techniques to allow for efficient cooling of the superconductor core with an extremely small footprint. The basis fiber structure includes a superconductor core, holes displaced around the core for the encapsulation of liquid nitrogen, and outer glass cladding. This novel design lends itself to various geometries and compositions. A composite fiber structure including a fiber optic core, conductor, and superconductor is envisioned as one such possibility. Our invention demonstrates a step change in superconductor cable designs, as well as the potential for significant advances in the efficient use of materials with existing manufacturing techniques.
