Abstract: Inductrack III configurations are suited for use in transporting heavy freight loads. Inductrack III addresses a problem associated with the cantilevered track of the Inductrack II configuration. The use of a cantilevered track could present mechanical design problems in attempting to achieve a strong enough track system such that it would be capable of supporting very heavy loads. In Inductrack III, the levitating portion of the track can be supported uniformly from below, as the levitating Halbach array used on the moving vehicle is a single-sided one, thus does not require the cantilevered track as employed in Inductrack II.

Abstract: Methods and systems for levitation on uncharged and non-magnetized arbitrary surface are disclosed. The levitation system generates electric fields in order to cause dielectric polarization on the surface on which levitation is to be caused. Methods and systems are disclosed in which the polarity of the electric field that is produced by the system is switched in a controlled manner. Due to kinetic inertia of the effective dipole moment of the uncharged and non-magnetized arbitrary surface, the dipole moment cannot maintain the changes in response to the changes in polarity of the electric field that is produced by the levitation system and thus, a repulsive force is generated between the levitation system and the non-magnetized arbitrary surface. The controlled repulsive force initiates and maintains the desired level of levitation with respect to the uncharged and non-magnetized arbitrary surface.
