In place of a propeller or paddle wheel, [the Yamato 1] uses jets of water produced by a magnetohydrodynamic (MHD) propulsion system.… Inside each thruster, the seawater flows into six identical tubes, arranged in a circle like a cluster of rocket engines. The ten inch diameter tubes are individually wrapped in saddle shaped superconducting magnetic coils made of niobium titanium alloy filaments packed into wires with copper cores and shells. Liquid helium cools the coils to –452.13°F, just a few degrees above absolute zero, keeping them in a superconducting state in which they have almost no resistance to electricity. Electricity flowing through the coils generates powerful magnetic fields within the thruster tubes. When an electric current is passed between a pair of electrodes inside each tube, seawater is forcefully ejected from the tubes, jetting the [craft] forward.

This thing could park a couple of hundred warheads off Washington and New York and no one would know anything about it till it was all over.

There's only one Yamato I am interested in:

Huh, magnets is actually the right answer for once!

Looks like it ought to go a lot faster than 8 knots.

The japs are indeed crafty folk, Give 'em six months, they'll figure out a way to have sex with the liquid helium magnets, AND make a coin operated version.

You know, just the other day it seemed like I heard magma displacements.
Go figure. |

Last time I heard that thing we do about 2 and a half Kts with a propulsion plant power about 3.5 megawatts. The big problem with these things, I seem to recall, is that very quickly the electric current applied to the sea water begins to cause hydrolysis and very quickly the energy that should go into moving the ship goes into making gas bubbles.

They will lay off our largest city, and listen to our "rock and roll"...
