Abstract To provide for electrical contact to conductive fluid circulating in a magnetic field, and power transfer between an output shaft and the circulating fluid (the power transfer direction depending upon whether the machine operates as a generator, or as a motor), a fluid-type housing of insulating material is provided to have the fluid circulating therein, electrically conductive zones are located in the housing to provide electrical connection, and rotating blades in the form of paddle wheels, or the like, sealed against the outside are placed in the moving, conductive fluid. In one form, the housing is formed of circular, insulating discs with conductive cylindrical end walls and a conductive center, around which a super conducting magnet is placed; fluid ducts lead off from the center and a peripheral region of the discs; to turn the paddle wheels; in another embodiment, a toroidal, ring-shaped conduit is formed with magnets placed staggered along the duct, with conductive zone on facing, opposite sides of the duct offset from the magnets, the rotor and its blades being located in a bulge formed in the duct and in mechanical driving power transfer relationship to fluid circulating around the toroidal ring duct.
