Potential NASA Commercial Applications: Manufacturers of large electrical systems desire to increase the efficiency, and decrease the size and weight of their systems in order to reduce costs. Presently manufacturers of transformers, motors, generators, fault current limiters, transmission cables, and magnetic resonance imaging (MRI) systems are pursuing superconductor wires to achieve these objectives. To make major cost improvements with superconducting systems, the barriers have been the higher cost of cooling at liquid helium temperature (4 K) for traditional metallic superconductors and the high wire cost for ceramic high temperature superconductors at 20-30 K temperatures. Low cost MgB2 superconductor wires operating at 4 25 K can overall lower the upfront and ongoing operational costs of superconducting systems. Potential Non-NASA Commercial Applications: Besides stator and rotor coils, magnesium diboride superconductors can benefit NASA applications for many applications where light weight power components are required such as cables, generators, motors, transformers, inductors, and power conditioning equipment. Other magnet applications that magnesium diboride wires can be considered for are magnetic shielding in space applications, ADR coils, magnetic bearings, actuators, MHD magnets, and magnetic launch devices.
