High-temperature superconductivity makes a bid for the power grid

Four wire strips made of the high-temperature superconductor BSCCO (foreground) can carry as much current as a copper cable about 100 times larger in cross-sectional area. American Superconductor

Workers assemble the first 1,000-horsepower high-temperature superconducting motor at a Rockwell Automation plant in Cleveland.
