Abstract
Abstract A method and an apparatus for propelling water vehicles in surrounding water are disclosed. The water has carriers of electrical charge. For propelling the water vehicle, the latter is provided with an elongate pipe being immersed in the water for allowing the water to flow therethrough along a longitudinal axis thereof. An electric field (E) is generated within the pipe with electric field lines extending radially with respect to the longitudinal axis. Further, a magnetic field is also generated within the pipe, the magnetic field having field lines extending circumferentially about the longitudinal axis. Thereby, a force (F) is exerted upon the charge carriers by simultaneous action of the electric field (E) and the magnetic field (B) on the charge carriers. The force (F) is directed parallel to the longitudinal axis to thereby propel the water vehicle.
