135K is still cool. <Oak Ridge National Laboratory is helping to make the dream of high-temperature (from 20 K up to 135 K) superconductivity a reality. Since 1988, our High-Temperature Superconductivity Technology Center has blended materials research and wire development through Cooperative Research and Development Agreements (CRADAs) with industry. In the coming decade, high-temperature superconductors will revolutionize much of industry and technology. ORNL researchers are partnering with U.S. industry to hasten the revolution.> I've been watching since 1996 for superconductors to make inroads into cyberphone base stations [to improve spectral efficiency]. It has been tough row to hoe. suptech.com I test drove a superconductor railway in 1990 in Japan [admittedly only a model, about 0.5 metres long, [the track, not the train, which was only 10cm long] but it was fun - they also had a melon supported by superconductor on a magnetic ring]. It's still in the thinking about it category. Mqurice
