Lifter in a Vacuum : Electrodynamic Ion Propulsion

This video shows a series of experiments of a ion craft / space ship propelled by high voltage, in a vacuum chamber at a series of different atmospheric pressures. If one wants to build an ion ship that is capable of traveling in outer space, the vacuum barrier must be overcome. Curiously as the vacuum pressure decreases, the electrical impedance decreases, as so does the thrust / lift of the lifter. T. Towsen Brown conducted similar experiments to validate his theories in Electrogravity and anti-gravity.
