Abstract:
1. An AC current generator comprising: a stator comprising an outer shell of non-magnetic material enclosing an evacuated chamber and having a distribution of a plurality of ferromagnets attached to an inner surface of said outer shell; a rotor comprising at least one inner core of non-magnetic material located at a stability location within said evacuated chamber and having a distribution of a plurality of diamagnets attached to an outer surface of said inner core, and at least one magnetic flux detection unit located within at least one magnetic field generated by at least one group of ferromagnets of said plurality of ferromagnets, wherein displacing said rotor from said stability location towards said at least one group of ferromagnets generates a change in magnetic flux in said magnetic field thereby generating an AC current in said at least one magnetic flux detection unit; wherein each member of said plurality of ferromagnets comprises a disc-shaped ferromagnet; wherein said outer shell of non-magnetic material is selected from the group consisting of aluminium, antimony, copper, gold, lead, magnesium, platinum, silver, tin, titanium, tungsten, vanadium and zinc and/or any combination thereof.
