Thanks, but I'm really seeking some stats, perhaps I can find them on the AMSC website. I'm all for greater efficiency, but my concern is that this could be a solution in search of a problem. Electric motors now are typically between 85 and 95% efficient, it might make sense to buy a more expensive but efficient electric motor (using a copper rotor for example), to go from 85% to 95%, but might not make sense at all for most applications to pay for a HTS motor to go from 95% to 97%, especially if that new HTS motor requires a liquid nitrogen cooling system to operate (added space, safety issues, and reliability issues).

I'm sure the Navy is considering all the issues and if I were a commerical shipbuilder I'd wait until I knew what the Navy's decided and why.
