Biefeld-Brown effect

The Biefeld-Brown effect is a phenomenon where a specially designed electrical device, called a capacitor with asymmetric electrodes, appears to generate a small thrust or force when high-voltage electricity is applied. This force seems to push the device upward or in a specific direction. Some researchers suggest this may be related to ion movement or electromagnetic forces in the air around the device, but no definitive scientific explanation has been confirmed. It’s often discussed in the context of advanced propulsion concepts, but the effect remains subtle and is not yet practical for propulsion systems.
