1. A transport device (23) for displacing over a floor for transporting at least one object and/or one person by means of at least one rolling device (3), the transport device (23) having:
a drive element (4) at least indirectly caused to rotate by the rolling device (3), wherein the drive element (4) comprises at least two drive magnets (12), an output element (7) comprising two or more output magnets (15) wherein the number of drive magnets (12) deviates from the number of output magnets (15), and the output element (7) is rotatable about an axis of rotation (11);
at least one non-magnetic shielding element (5) adapted and configured for modifying the alignment of the magnetic field disposed between the drive element (4) and the output element (7), and
at least one stator winding (8) disposed adjacent to the output element (7) in a manner such that when the output element (7) rotates about the axis of rotation (11) electric current is generated in the at least one stator winding; and
electrical contacts (10) configured for directing the electric current generated in the at least one stator winding (8) to a battery, the battery being configured for providing power to a device (24) other than the transport device (23).
