Biefeld–Brown effect

The Biefeld -Brown effect is a 1920 by Thomas Townsend Brown discovered in 1923 by Paul Alfred Biefeld at the Denison University in Granville (Ohio ), investigated physical phenomenon which is characterized by a thrust in the direction of the smaller plate of a charged high voltage asymmetric capacitor expresses.

The Biefeld -Brown effect is most likely generated by accelerated in the electrode array ions. Of the smaller plate of the capacitor molecules of the surrounding medium due to the high electric field strength there are ionized and accelerated in the direction of the larger plate. They tear through collisions with other non- ionized molecules and thus produce a net thrust which pushes the capacitor toward the smaller plate. Theories in this field builds on the plasma physics.

An often alleged ( by TT Brown) Biefeld -Brown effect in vacuum has not been previously occupied by reputable experiments. Further, it is often claimed, especially by pseudo-scientific sources that the effect on electric gravity, an unknown coupling of the electromagnetic field is, due to the gravity. This is rejected by scientists: First Experiments with lifters, small aircraft whose driving principle presumably based on the Biefeld -Brown effect that the strength of the shear force does not depend on the position and orientation of the device in space, and especially with the ground, which a gravitational effect excludes. On the other hand, the effect in the normal physics can quite explain.

For simple detection can be used a torsion balance, at the end of an asymmetrically constructed condenser is attached, which is at a high voltage source of direct current.
