Claims

1. A MAGNETOHYDRODYNAMIC EFFECTS CRAFT ADAPTED TO TRAVEL THROUGH A SURROUNDING FLUID MEDIUM WHEREIN THE ZONE OF THE MEDIUM ADJACENT THE CRAFT IS RESPONSIVE TO MAGNETIC FIELDS TO CONDUCT MUTUALLY INDUCED EDDY CURRENTS, COMPRISING A PLURALITY OF ELECTRICALLY CONDUCTIVE COIL MEANS CAPABLE OF PRODUCING MAGNETIC FIELDS SURROUNDING THE CRAFT UPON CONDUCTION OF ELECTRIC CURRENT THERETHROUGH ARRANGED SERIALLY ALONG AN AXIS OF THE CRAFT PARALLELING A DESIRED DIRECTION OF TRAVEL, MEANS FOR APPLYING POLYPHASE ALTERNATING CURRENT ELECTRIC VOLTAGES TO SAID COIL MEANS TO PRODUCE A PLURALITY OF MAGNETIC FIELDS FLUCTUATING RESPONSIVE TO ALTERNATING CURRENTS IN SAID COIL MEANS WHICH ARE PHASED AND MAGNETICALLY SUPERIMPOSED TO PRODUCE A COLLECTIVE DRIVING MAGNETIC FIELD SURROUNDING SAID CRAFT WHOSE POINT OF MAXIMUM FLUX DENSITY REPETITIVELY PROGRESSES FROM A LEADING END POSITION RELATIVE TO SAID DIRECTION OF TRAVEL TO A TRAILING END POSITION, AND SWITCHES BACK TO SAID LEADING END POSITION, SAID DRIVING MAGNETIC FIELD BEING OF SUFFICIENT STRENGTH TO INDUCE EDDY CURRENTS IN THE ADJACENT ZONE OF SAID FLUID MEDIUM AND THEREBY CONSTITUTE THE FLUID MEDIUM AN EQUIVALENT ELECTRICAL CONDUCTOR INTERACTING WITH SAID DRIVING MAGNETIC FIELD TO BE DRIVEN IN THE DIRECTION OF TRAVEL OF THE DRIVING MAGNETIC FIELD AND EFFECT PROPULSION OF SAID CRAFT IN THE SELECTED DIRECTION OF TRAVEL.
