In August 1990 the U.S. Air Force Astronautics Laboratory at Edwards Air Force Base published "Electric Propulsion Study" (AL-TR-89-040), a report by physicist Dennis Cravens of Science Applications International Corporation (SAIC) that included an examination of whether electromagnetism and gravity might be coupled in ways usable for space propulsion.[1][2]
Background
The study was carried out from September 1988 to November 1989 under an Air Force technical assistance contract, with Franklin Mead as the Air Force task manager and physicist Pharis Williams as the main consultant, as part of the laboratory's look at future propulsion possibilities.[1]
Contents
The report reviewed theoretical ideas and claimed experiments, including the Biefeld–Brown effect, a "conductive submarine" and a "gravitational rotor", and explored the idea of inductive coupling between electromagnetic and gravitational forces. It concluded that such effects were speculative, with no confirmed basis for building a propulsion system, and recommended further study of radiation pressure and Biefeld–Brown effects.[1][2]
Context
The report was part of a long series of Air Force propulsion studies, from Project Outgrowth in 1972 to Veritay Technology's 1988–1991 tests of the Biefeld–Brown effect, which found no thrust in a vacuum. None of them describes working technology. The report is publicly available through the Defense Technical Information Center.[1][3][4]
