Ionocraft

Ionocrafts (otherwise known as "lifters") are devices that propel themselves into the air without any physical moving parts. They're popular as "science fair" projects because they are relatively simple to produce but aren't particularly powerful - so don't expect the F3600 to be coming to a sports channel near you any time soon.

[edit] Basic construction

Very basic lifters usually consist of a Balsa wood frame that is tethered to the ground with some loose string. Around the frame a strip of tin foil (with it edges rounded) is fastened. The frame holds a thin metal wire just above the tin foil. The wire and the tin foil are connected to the two ends of a high voltage DC power supply, serving the purpose of electrodes.

[edit] Theory of operation

When high voltage is pumped into the system, the air between the two electrodes is ionized (meaning, the electrons are stripped and transferred from it) by a corona discharge. This causes the ionized air to move from the wire to the tin foil. Collisions with neutrally charged air molecules creates a net force, a "wind" that propels it into the air.[1] This effect is called the Biefeld–Brown effect.

[edit] "Alternative" (cough cough) theories of operation

Since one of the men who discovered the Biefeld-Brown effect, Thomas Townsend Brown, believed that the effect may provide an explanation for UFO flight, lifters have created a large buzz in the UFO community. They tend to believe that lifters are not propelled by the ionization of air, but by anti-gravity. The problems with this is that lifters have been shown not to work in a vacuum (no air to ionize).
