Abstract

An apparatus is disclosed for the propulsion of water vehicles. A magnet field as well as an electric field with essentially perpendicular field lines are produced in a pipe through which surrounding water flows. In this manner, a force is exercised upon charge carriers within the surrounding water and this force is used as a propulsion force for the water vehicle. The pipe is surrounded by a solenoid coil which is arranged essentially coaxially to the pipe. A first electrode is arranged essentially along the axis of the pipe and a voltage source is switched between the electrode and the pipe, acting as a second electrode. An Archimedes' screw is arranged in the cylindrical gap between the electrode and the pipe in order to deflect the surrounding water circulating about the axis into an axial direction, or the screw is rotationally rigidly connected to a moving conductor arranged perpendicularly to the direction of the magnet field.
