The Biefeld–Brown effect is an electrical phenomenon, first noticed by inventor Thomas Townsend Brown in the 1920s, where high voltage applied to the electrodes of an asymmetric capacitor causes a net propulsive force toward the smaller electrode.Brown believed this effect was an anti-gravity force, and.

By a design of the structure of capacitors, the performance enhancement in ASC can be expected by the synergistic effect of non-faradaic capacitance and pseudocapacitance, which is confirmed with three different measurements: cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) determine the pseudocapacitive
When a high voltage (~30 kV) is applied to a capacitor whose electrodes have different physical dimensions, the capacitor experiences a net force toward the smaller electrode (Biefeld-Brown
We have verified this effect by building four capacitors of different shapes. The effect may have applications to vehicle propulsion and dielectric pumps.

This last winter under a government funded effort we tested our Asymmetrical capacitor devices in both Air (atmospheric conditions) and Vacuum ( lower than 4.5x10^-6 Torr). In both test cases the results were identical. ac ripple or impulse signals can have a marked effect on the output response of these types of devices and he was only
The phenomenon of the force originating on the high voltage asymmetrical capacitors is known for more than 80 years. There even has been a growing interest in this so called Biefeld-Brown effect in the recent years. 1 However the detailed description of all interesting aspects of this phenomenon is missing. One very important aspect is the existence

When a high voltage is applied on an asymmetric capacitor, it experiences a force acting toward its thinner electrode.

The high voltage was provided to the capacitors by the high-voltage power supply ( see Fig. 1 for a scheme). When such a power supply was switched on, the two asymmetrical capacitors began to rotate and accelerate quickly up to high speeds.
Our experimental measurements indicated the presence of a small, but persistent force in the scale of mgf, mainly for high values of the high voltage applied such as 6 kV on the asymmetrical capacitor, with maximum value for the force 278.83 mgf, for the maximum voltage applied (up to 6 kV) on the device sample.
Some different independent experiments [ 7] performed with asymmetrical capacitors as lifters using air as dielectric seem to indicate that such an effect can be possible, that is, the devices present anomalous variations of their weights or even levitation when they are subjected to the regime of high voltage applied.
These asymmetric capacitors became known as Asymmetrical Capacitor Thrusters (ACT). The Biefeld–Brown effect can be observed in ionocrafts and lifters, which utilize the effect to produce thrust in the air without requiring any combustion or moving parts.
