This is an interesting video: NASA Chief (Dr. Charles Buhler): We Just Built Antigravity Propulsion!

Here's the description from https://www.youtube.com/@JesseMichels (American Alchemay):

Dr. Charles Buhler has run 2,000 vacuum chamber experiments showing a propellantless thrust force that persists after the power is switched off, and cannot be explained by ion wind, magnetic effects, or classical energy conservation. The input is pure electricity and the output is millinewtons of thrust counteracting gravity. He believes his work vindicates the legacy of midcentury antigravity pioneer Thomas Townsend Brown and will lead to the future of propellantless deep space travel.
