EFFICIENCY: Simple Superconductors With ORNL Method.

Energy Optimization News, August, 2004

A simplified chemical solution approach to producing a second generation (2G) high-temperature superconductor (HTS) wire has resulted in high electrical current performance. Researchers from the Department of Energy's Oak Ridge National Laboratory (ORNL; Website: http:// www.ornl.gov/HTSC/htsc.html), the University of Tennessee (UT), and American Superconductor Corporation of Westborough, MA have successfully demonstrated a superconducting wire sample produced by using all-solution methods that carried an electrical current of 140 amperes in liquid nitrogen meeting their key performance milestone for 2004, which was to exceed 100 amperes. The results were presented at the annual Department of Energy (DOE) Peer Review meeting in Washington on July 28.
