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. Additionally the source of electric fields is made to have a large area in order to increase the repulsive force on the levitation system.
