Abstract
A propulsion system has a means generating an electric current, an element generating a magnetic field substantially perpendicular to the electric current, an element forming a duct arranged so that by interaction of the magnetic field and the electric current a force in a liquid accommodated in the duct is produced and the liquid is moved, and a shaped element formed so that the moved liquid passes through the shaped element and applies a thrust force to the shaped element in a forward direction and then exits the shaped element to create a reaction force in an opposite direction to provide an additional thrust force applied to the shaped element.
