Yamato-1: Das weltweit erste Schiff mit magnetohydrodynamischem Antrieb

The original could do 8 knots, which doesn’t sound like much but it was just a proof of concept.

If/when much higher temperature superconductors are found I think you will see this concept revisited.

I read the article, and if I understand correctly, the machine has a base plate of pre-famulated amulite surmounted by a malleable logarithmic casing in such a way that the two spurving bearings were in a direct line with the panametric fan. The latter consisted simply of six hydrocoptic marzlevanes, so fitted to the ambifacient lunar waneshaft that side fumbling was effectively prevented.
Now basically the only new principle involved is that instead of power being generated by the relative motion of conductors and fluxes, it is produced by the modial interaction of magneto-reluctance and capacitive diractance.
The main winding was of the normal lotus-o-delta type placed in panendermic semi-boloid slots of the stator, every seventh conductor being connected by a non-reversible tremie pipe to the differential girdle spring on the “up” end of the grammeters.
