Remember high-temperature superconductors? These high-tech darlings of the late 1980s brought a Nobel Prize to their discoverers and generated endless speculation about how their near perfect conduction of electricity would revolutionize the world we live in! A key obstacle in realizing large-scale applications of these novel materials was the difficulty of forming long, flexible wires that can carry large amounts of supercurrent per unit area, from these highly brittle, ceramic superconductors that essentially resemble “mud”.It turns out that from a technical or performance standpoint, a mile-long, flexible, single-crystal-like wire of the highly brittle, ceramic superconductor was required. From a cost and fabrication standpoint, an industrially scalable, low-cost process was needed with the goal being to meet or beat the price of ordinary copper wire! This constituted the first holy-grail in fabrication of high-performance, superconducting wires, namely, fabrication of single-crystal-like superconducting wires by the kilometer at a price/performance metric equivalent to that of copper. Once this seemingly insurmountable objective was addressed via fundamental technical innovations, a second holy-grail became apparent for realizing large-scale applications where high-applied magnetic fields were present. This related to substantially improving the vortex-pinning within the superconducting wires which could only be accomplished by introducing periodic, nanoscale, non-superconducting regions separated by nanoscale dimensions, within kilometer-long superconducting wires. Of course, all of this had to be accomplished without adding any significant cost! In this talk Professor Amit Goyal of the State University of New York (SUNY) at Buffalo will take you on a journey from the discovery of high temperature superconductors towards realizing practical, large-scale, applications of these novel materials by addressing the key scientific and technical challenges mentioned above. The eventual solutions are one of the first, large-scale, high-technology applications of nanotechnology, the only example of "epitaxy-by-the-mile" and of self-assembly of nanomaterials by the mile! These HTS wires are now enabling commercial nuclear fusion for limitless clean energy generation, loss-less transmission of energy, superconducting magnetic energy storage systems, next-generation MRI and NMR, MagLev for transportation and all-electric planes and ships with superconducting drivetrains for defense applications.
