Dr. Charles Buhler has run 2,000 vacuum chamber experiments showing a propellantless thrust force that persists after the power is switched off, and cannot be explained by ion wind, magnetic effects, or classical energy conservation. The input is pure electricity and the output is millinewtons of thrust counteracting gravity. Youtube Our American Alchemist had a long interview this week with Dr. Charles Buhler.

This work if it is true is better than cancelling gravity. This is using no propellant to create thrust that counters or applies force for propulsion and other effects.

The effect and propulsion if real would already be useful for no fuel maintenance of orbits for satellites.

Increasing the propulsion effect are materials that can handle higher voltages and other material properties.

The founders have their own vacuum chamber and are building a larger walk-in vacuum chamber.

They have eliminated issues about ion wind which is a propulsive force.

A true electrostatic pressure force that enabled unlimited propellantless drive with nuclear power sources for years of acceleration would enable drives that could reach near light speed. Interstellar and interplanetary travel would be possible. It would become similar to the world of the Expanse TV show.

Nextbigfuture has covered this work before.

Buhler has tried to use standard physics QED (Quantum Electrodynamics) to explain what he is seeing. There was some prior work that used QED to explain Coulombs Law. Coulombs Law explaining everything that we know about two atoms and two charges. Coulombs law is more complete than the simplified Maxwell equations. The effect has to do with exchanging virtual particles. His physics theory discussion starts around 1hour 55 minutes into the video.
