It uses super-conductivity to facilitate levitation. Flux pinning creates an 'on-rails' movement between the two components (the superconductor and the magnetics on the ground). Defects in the magnets and gaps would create areas of resistance, much like they do in toy-scale versions of this same concept, but you'll still be pinned to the magnetics as long as that superconductor stays cold. There will be no 'astronaut-in-space' movement, because the board will only be able to achieve quantum levitation over a bed of magnetics, which will be many pieces and not defect-free. http://quantumlevitation.com/the-physics/ http://quantumlevitation.com/the-physics/ http://www.ted.com/talks/boaz_almog_levitates_a_superconductor?language=en http://www.ted.com/talks/boaz_almog_levitates_a_superconduct...
