A futuristic power system installed on a Japanese experimental ship (Yamato 1). It can achieve only six knots, which is a long way from catching the 40-knots-plus jetfoils. But it is as remarkable as the first steam-ship: it has no paddles, propellers or jet-driver. Actually, it has no mechanical power-transmission system at all. But it relies on the "Lorentz force" - i.e. a thrust that is generated when a magnetic force is applied vertically into the water and an electric current discharged horizontally across its path.  1, fiche 1, Anglais, - superconducting%20electromagnetic%20propulsion%20system

SEMP thrusters are made up of superconducting magnets wrapped around ducts in the hull of Yamato 1. Electrodes pass a current through the seawater as it is drawn into the front of the ducts. The magnets, cooled at -269° C, then punch a huge magnetic force into the water. The resulting "Lorentz force" causes the water to squirt through the rear of the ducts to propel the ship along.  1, fiche 1, Anglais, - superconducting%20electromagnetic%20propulsion%20system
