Biefeld-Brown effect

Both do exert pressure but the radiation part is orders of magnitude more powerful. Below the glow discharge region, the breakdown voltage increases again, whilst the number of potential ions decreases, and the chance of impact lowers. This leads to a Coulomb force and change of momentum so small as to be zero.

Biefeld–Brown effect

biedeld Usually, two electrodes are used with a high voltage between them, ranging from a few kilovolts and biefels to megavolt levels, where one electrode is small or sharp, and the other larger and smoother. It is likely that the reason for this is that at very low pressures, only experiments which used very large voltages produced positive results, as a product of a greater chance of ionization of the extremely limited number of available air molecules, and a greater force from each ion from Coulomb’s Law; experiments which used lower voltages have a lower chance of ionization and a lower force per ion.

Brown was granted a number of patents on his discovery:.

With a large enough power supply, it shouldn’t matter how little thrust this produces, so long as it produces even a miniscule thrust: Inhomogenous field is produced by applying dc bias between a horizontal flat electrode and the tip of a conical bottom electrode of an electrostatic capacitor. The article also mentioned the “gravitator,” an invention by Brown which produced motion without the use of electromagnetism, gears, propellers, or wheels, but instead using the principles of what he called “electro-gravitation.


That’s not to say something like this is completely unfeasiable; Dr.

For nearly a century, physicists have had two definitions, one proposed by German physicist Max Abraham and another derived by German mathematician Hermann Minkowski. If the electric field pointed up and the magnetic field pointed north, then virtual photons of a given energy traveling east would have a different biefels from those traveling west.

The lifter is bieefeld an open electrostatic ion engine, using the atmosphere or solar wind as a working medium. Around the same biefld inresearchers from the Army Research Laboratory ARL tested the Biefeld—Brown effect by building four different-sized asymmetric capacitors based on simple designs found on the Internet and then applying a high voltage of around 30 kV to erfect. This page was last edited on 13 Decemberat Additionally, I wonder how it compares to closed case ion drives, lets say if you injected some propellant into the electrostatic field Whether this increases or decreases the maximum momentum of the ionized air is not typically measured, although the force acting upon the electrodes reduces, until the glow discharge region is entered.

The back-action follows from changes in momentum of quantum vacuum fluctuations zero-point energygenerated in magneto-electric materials. Apparently, there is a worldwide club of science hobbyists that are reproducing this effect unlike the unreproducible hiefeld of cold fusion in a bottle a few decades agoand competing for larger designs and greater weight Lifters.


A resonant suspension is used to detect its motion. The use of an asymmetric capacitor, with the negative electrode being larger than the positive electrode, allowed for more thrust to be produced in the direction from the low-flux to the high-flux region compared to a conventional capacitor.

This leaves a cloud of positively charged ions in the medium, which are attracted to the negative smooth electrode by Coulomb’s Lawwhere they are neutralized again. Brown filed another patent in that detailed the physics of the Biefeld—Brown effect, making the following claims: Simon If you’re talking about the lightcraft, there has actually been some testflight, I think it went to ft or so, problem is, it’s gotta be very light and need a powerful laser as for the lifters, yep it ionises air around and use it to move, and in this case too needs to be very light.


I had got ahold of the original patents by a guy named de Seversky. This site uses cookies. I’m pretty sure this is just ionising air stripping off some of the electrons from the N2, for exampleand driving them through the electrical field between the strips of Aluminum foil; your TV does a similar thing when it take a cathode-ray a beam of electrons and uses electrical and magnetic fields to bend the beam in such a way to draw pictures on your screen Anyway, here are some links: As air pressure is removed from the system, several effects combine to reduce the force and momentum available to the system.

Historically, numerous patents have been granted for various applications of the effect, from electrostatic dust precipitation, to broqn ionizersand also for flight. This effect may provide new tools for investigation of the quantum nature of our world.

I’ll note that JP Aerospace is planning on this sort of propulsion for their space blimps There have been follow-ups on the claims that this force can be produced in a full vacuum, meaning it is an unknown anti-gravity force, and not just the more well known ion wind.
