Ning Li is an American scientist best known for her controversial claims about anti-gravity devices. She previously worked at the University of Alabama, but left to form her own company AC gravity LLD. The whereabouts of Ning Li are currently unknown......
According to Li, rotating ions create a gravitomagnetic field perpendicular to their spin axis. If a large number of ions could be aligned, (in a Bose-Einstein condensate) the resulting effect would be a very strong gravitomagnetic field producing a strong repulsive force. The alignment may be possible by trapping superconductor ions in a lattice structure in a high-temperature superconducting disc.See also
