Hang on, the NASA researchers say (as Mike has noted with annoyance):
<3.2.7. Biefeld-Brown and Variants. In 1928 a device was patented for
creating thrust using high-voltage capacitors [50]. Since then, a wide
variety of variants of this "Biefeld-Brown" effect, such as "Lifters" and
"Asymmetrical Capacitors" have claimed that such devices operate on an
"electrostatic antigravity" or "electrogravitic" effect. One of the most
recent variants was patented by NASA-MSFC [51]. To date, all rigorous
experimental tests indicate that the observed thrust is attributable to ion
wind [52-54].
Vacuum tests currently underway, sponsored through an additional
Congressional earmark to the West Virginia Institute for Scientific
Research, also indicate that this effect is not indicative of new
propulsion physics. These tests are now assessing the more conventional
performance of such devices [55].
These "Biefeld-Brown," "Lifter" and "Asymmetrical Capacitor Thrusters" are
not viable candidates for breakthrough physics propulsion. >
