Biefeld-Brown Effect

The Biefeld-Brown effect produces thrust in an asymmetric high-voltage capacitor — no moving parts, no fuel combustion. A sharp emitter wire at high voltage creates a corona discharge, ionizing air molecules. These ions accelerate toward the grounded collector, dragging neutral air along and generating a net ionic wind force. The visualizations below explore the plasma physics, electrohydrodynamic (EHD) thrust mechanics, and electric field geometry.
