Superconducting materials motors

In 1996, a 50 m underground superconducting cable (wound from 6 km of a BSCCO ribbon) and a 150 kW superconducting electric motor were successfully demonstrated. Further development of practical superconductor devices might well depend more on the development of suitable refrigeration technology than on the preparation of new superconducting materials.

Electric power is produced by spinning a magnet inside a coil. The use of superconducting materials allows one to make electric motors and generators that are more efficient than the conventional generators woimd with copper... 

Can these superconducting motors and bearings be combined to create that nonpolluting, quiet, simple-starting dream vehicle, the electric car Perhaps. Room-temperature superconductors seem to be close at hand, and engineers have been able to build smaller motors and chassis with lighter materials, and space-age fuel cells that are similar to batteries but which draw their energy from a chemical fuel that is supplied while the cell is in use.
