In The propeller is giving way to the pump-jet propulsor on larger submarinesInteresting. If I understand correctly, they need a electrode that's in physical contact with the sea water. I'm not sure I understand it entirely, but there's a video on the Tech Ingredients channel that explains magnetohydrodynamic pumps: [VIDEO]
