Basically, you pass a magnetic field through the medium in one direction, an
electric field through 90 degrees to the magnetic and the medium will flow
in a direction perpendicular to both fields.  So, the medium must be bipolar
(H2O is) and pass electric current. H2O doesn't very well in a pure state,
so I believe this only works decently in salt water.....That's what I
remember without looking it up, so I may be wrong.

Try submitting a bit about it and some pictures to New Scientist, Scientific
American, Popular Science and Popular Mechanics, because anyone who has
enough money to develop one of these things and knows a bit about subs would
love to have one of these things, especially if it is more efficient that a
prop.

Just out of curiosity; how does this thing work? I've heard about E-MHD
systems before (Hunt for the Red October, the Yamato 1), but have never
heard
quite how the system is supposed to work.
