Biefeld–Brown effect - debunked

The Biefeld–Brown effect is an effect that was discovered by Paul Alfred Biefeld (CH) and Thomas Townsend Brown (USA). The effect is more widely referred to as electrohydrodynamics (EHD) or sometimes electro-fluid-dynamics, a counterpart to the well-known magneto-hydrodynamics. Extensive research was performed during the 1950s and 1960's on the use of this electric propulsion effect during the publicized era of the United States gravity control propulsion research (1955 - 1974).

An article by Martin Tajmar (see below, or a summary) describes an experiment designed to test the possibility that this effect may need some other effect than ion winds for its explanation. No such effect was found, to the limit of experimental accuracy. In particular, no thrust could be observed in a vacuum

The fantastic floating device called a lifter has no moving parts, no onboard fuel, and no shortage of wide-eyed admirers. Even inside NASA.
