Current limits to wire technology

摘要: High-temperature superconductors could be a boon to the power industry, carrying large currents with virtually no energy loss. Unfortunately, these brittle materials are difficult make into wires, so in practice they powdered and encased silver strips, drawn out align powder crystallites. But current capacity of tapes is still severely limited. That probably due misalignment crystallites, according new magnet-optical imaging studies. So for commercial applications, slightly different processing strategies may needed — or an entirely type tape.
