ABSTRACT:
Apparatus, systems and methods for levitating and moving objects such as vehicles, doors and windows are shown and described herein. The embodiments incorporate a track with lower rails having lower permanent magnets and the object with upper rails having upper permanent magnets aligned with the lower rails and oriented to oppose the polarity of the lower permanent magnets. Ferrous backing plates may be incorporated behind the lower rails and/or the upper rails. Embodiments may also incorporated a third rail of an electroconductive material, and a driving disc positioned near the third rail. Permanent magnets in the driving disc may be rotated with the driving disc in the presence of the third rail to accelerate the upper rails with respects to the lower rails. The driving disc may be coupled one of the lower rails to maintain a desired alignment with the third rail.
