Dr. Ning Li published three notable papers on her experiments with superconductors which suggest interactions between the gravitational, electric and magnetic fields; further evidence that the three really are but aspects of the same field.

In her third and last paper before her mysterious disappearance she mentions her team demonstrated that its really lattice-ions, not Cooper pairs that execute coherent localized motion consistent with the phenomenon of superconductivity. Further, her and her colleagues show that “coherent alignment of lattice ion spins will generate a detectable gravito-magnetic field, and in the presence of a time-dependent applied magnetic vector potential field, a detectable gravito-electric field.” This essentially means that gravity, electricity, and magnetism are not only undulatory manifestations of the same substance in different states, but also that each state can induce one another like a gear differential system.
The implication for this is a hoverboard that does not need to carry the energy to keep superconducting discs cooled and that can take advantage of the gravito-magnetic and gravitoelectric field interactions in designing via magnetic field architecture a geometry that repels the earth’s gravitational field with diminishing strength given distance in an inverse-square relationship. “Using about one kilowatt of electricity, Li claimed, her device could produce a force field that would effectively neutralize gravity above a 1 foot in diameter region extending from the surface of the planet to outer space. To demonstrate their research, they invited officials from the renowned science and technology magazine, Popular Mechanics, to visit their laboratory in Huntsville to see their work-in-progress, a 12-inch disk which acted as a HTSD. Upon the disc’s completion, they told the magazine, a bowling ball placed anywhere above this disc will stay exactly where you left it.” In 1999, Li left UAH to start her own company, AC Gravity, and commercialize a device based on her theories. Her colleagues obviously believed in her work as the chair of UAH’s Physics Department, Larry Smalley, also departed the university to join her. Public records show that in 2001, the U.S. Department of Defense gave AC Gravity a grant for $448,970 to research the technology. However, these results were never published.
In fact, Dr. Li never published anything again. And even though the business license for AC Gravity was updated yearly through 2018, there is no record of any further work done by the company.
Fixed superconductors in phase (coupled) with the earth’s gravitational field are able to invert, dampen, or strengthen the force of gravity as a voltage is applied to them. This is profound in that to have a hovering board able to carry any load all that would be necessary are room-temperature superconductors and fixed neodymium magnets in a specific geometrical arrangement for a coupled, resonant magnetic field and gravitational field architecture so that motion towards any direction at any speed is effortless and expends no more energy than staying still. Alternating current gravity is essentially altering the usually direct electrodynamic (electrostatic is a misnomer) current that imparts downward acceleration upon all gross matter.
Li’s career after 2002 is unknown. There is a document showing that she gave a presentation at the 2003 MITRE conference titled “Measurability of AC Gravity Fields.” The MITRE Corporation manages federally funded research for several U.S. agencies. At the conference, she presented along with a Redstone Arsenal official from U.S. Army Aviation and Missile Command, meaning that her research was still being conducted up to that point.
The trail on Li ends after her last documented correspondence in May 2003 when she sent a private email to colleagues claiming to have conducted an experiment in which she observed an “11-kilowatts of output effect.” The significance of that amount is still a mystery as well.
Her absence did not go unnoticed. In 2004, journalist Tim Ventura sent an email to another scientist in the field named Eugene Podkletnov with the subject line “Tracking Down Dr. Ning Li.” In the email, Ventura writes, “Every 2 months, I re-try the lining@comcast.net email address that you gave me for Dr. Ning Li — I can tell from return-receipts that somebody is reading her email, but I never get a reply.”

Podkletnov responded, confirming her wellbeing and that she was still working with the DoD but unable to talk about her work. He also told Ventura that he was unable to get a working email address or phone number for her.
As the years passed, the conversation regarding Li’s whereabouts started to amplify along with the conspiracies around it. In July of 2008, a scientist named Jack Sarfatti provided a rather alarming update during an interview that was later posted on YouTube and included in the video from Barely Sociable.
During the interview, Sarfatti claims that Li was no longer working for the DoD and had moved back to China to continue her work. The transcript of the interview conveys the seriousness of this accusation.
“This is very important from a national security and political point of view. One of the key scientists ….. is a Chinese woman named Ning Li. She has disappeared and gone back to China,” said Sarfatti. “She was working at NASA and the Redstone Arsenal but she has disappeared for several years now. The people at The Pentagon cannot reach her anymore. She is allegedly back in China and the Chinese are pouring money into similar experiments now. That’s why our intelligence guys are very interested. The most likely people to develop the first anti-gravity propulsion technology are the Chinese.”

Maybe ionize the borders or something and lean to control idk this is all conjecture obviously but the fact that gravity-shielding and tractor beam technology is there is undeniable as it has been empirically demonstrated via experiment.
The issue is that our modern physical theory is at a loss when trying to explain how alternating magnetic fields can generate gravitational fields akin to how alternating electric fields generate magnetic fields. It becomes stupefyingly simple when one realizes there is only one field undergoing state and energy transformations to yield emergent phenomena we take to be distinct.
