here's a clip from

"The search to tap electromagnetism has been going on for decades, and researchers have approached it both theoretically and in actual experimental application. Electrogravitics is described as a synthesis of electrostatic energy and gravitics, which sets up a local gravitational force independent of the Earth's. The essence of electrogravitic thrust is the use of a very strong positive charge on one side of a vehicle and a negative on the other, producing a driving force from a region of high-flux density to low-flux density. Scientists first began considering this propulsion concept in the 1920s, but the field literally took off after World War II when American physicist Thomas Townsend Brown constructed a prototype aircraft propelled by electrogravitic force.
Brown designed and built a flying aircraft whose thrust was derived by an electrogravitic charge combination, a feat he repeated many times with demonstrations witnessed by scientists and the military."
Has anyone else ever heard of "American physicist Thomas Townsend Brown"?
(I found this site while searching for exotic new energy sources- things on the bleeding edge of physics research. This is from one of the pages I found.)
edit: I discover from the same page that the above excerpt is from a book... sold on the site. Imagine that.
