Ships of the past were propelled by wind or by oars; contemporary ships are propelled by ejection of water towards the back of the ship using either a propeller or a pump; but the Kinetic energy of the water is lost/wasted; I have invented a propulsion system in which the water is ejected to the back of the ship using a pump through a pipe, on the end of which is fixed a divergent pipe that acts as a diffuser, of such shape and dimensions that the water in it slows its speed (to the back of the ship) to the same speed as is the forward motion of the ship; consequently the absolute speed of the water to the back of the ship (measured according to the bottom of the sea,) is zero, and therefore the theoretical efficiency of this propulsion system is 100%.
