NASA Anti-Gravity Files Revealed: The Ning Li Story

Tonight we will be holding a special event to commemorate the life and accomplishments of Chinese American Physicist Dr. Ning Li - a superconductor researcher who worked at the Center for Space Plasma and Aeronimic Research, University of Alabama in Huntsville in the 1990s.
In 1999 she left the university to form a company, AC Gravity, LLC to continue her anti-gravity research. The company was given a U.S. DOD grant for $448,970.00 in 2001 to continue anti-gravity research. The grant period ended in 2002 but no results were ever made public.

In a series of papers co-authored with fellow university physicist Douglas Torr and published between 1991 and 1993, she claimed a practical way to produce anti-gravity effects. She claimed that an anti-gravity effect could be produced by rotating ions creating a gravitomagnetic field perpendicular to their spin axis. In her theory, 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.
