New Superconductor Wire Beats High Current-Carrying Goal
American Superconductor Corporation announced on October 29th that its latest flat wire product made from high-temperature superconductor (HTS) materials significantly exceeds DOE's goals for carrying current. The company's 10-meter lengths of tape-like HTS wire can carry at least 100 Amperes of current per centimeter of width, which is more than double DOE's goal. DOE was aiming for December 2003 when it set the goal, so the company's achievement is also early. Tests at DOE's Oak Ridge National Laboratory verified the performance of the company's second-generation, coated-conductor wire.
American Superconductor expects to continue its rapid pace of development, thanks to a recent $2 million cost-shared grant from the U.S. Department of Commerce. The grant will go towards a scale-up of its manufacturing process, with the aim of commercially producing limited volumes of the wire by 2005. The company claims the new wire should perform the same as its current HTS wire product, but at as little as one-fifth the cost.
