I thought they felt it could allow for high speeds with no cavitation, and no concerns about approaching or exceeding the speed of sound under water on any surfaces...no cavitation.

Magnetohydrodynamic? It works. However, it requires lots of power, may attract magnetic stuff to the sub, and is not completely silent (big generators for the power, and with high currents electrolysis may become a problem).
