High-Temp Superconducting Tape

DrLudicrous writes "The NYTimes is running a little overview of the current state of mass produced superconducting materials. A company named Superpower (another blurb on them here) is making a layered superconducting tape out of ceramic materials- ceramics that are high-temperature superconductors (no resistance at liquid nitrogen temperatures, 77K). This is much cheaper to maintain than technologies based on superconducting metals, which tend to require liquid helium (~4 Kelvin) temperatures. A note of contention: the article mentions that superconductivity is not well understood -- high-temperature superconductors are not, but classical 'low-temperature' superconductors are well-described under the Bardeen-Cooper-Schrieffer (BCS) theory."
