Patent application US2007170798 is for a “Device of levitation of an item over an optimized base by means of permanent magnets. The equilibrium is stable along one or two axes by means of these permanent magnets, and along the one or two others by means of a combination of electromagnets of near zero consumption at equilibrium.” Click on the video to see it in action. The invention is reminiscent of the frog-levitating apparatus and theory by Geim and Berry honored with the 2000 Ig Nobel Prize in physics.
Thanks to investigator Manaz Ganji, who works with Janick Simeray, the inventor, for bringing this to our attention.)
