Electrogravitics

Not to be confused with Gravitoelectromagnetism, in which gravity behaves similarly to electromagnetism.

Electrogravitics is claimed to be an unconventional type of effect or anti-gravity force created by an electric field's effect on a mass. The name was coined in the 1920s by the discoverer of the effect, Thomas Townsend Brown, who spent most of his life trying to develop it and sell it as a propulsion system. Through Brown's promotion of the idea, it was researched for a short while by aerospace companies in the 1950s. Electrogravitics is popular with conspiracy theorists, with claims that it is powering flying saucers and the B-2 Stealth Bomber.

Since apparatuses based on Brown's ideas have often yielded varying and highly controversial results when tested within controlled vacuum conditions, the effect observed has often been attributed to the ion drift or ion wind effect instead of anti-gravity.[1][2]
