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. Unfortunatly, being a shock-driven process, the structural integraty of vehicle degrades quickly, in addition to only being useful in the lower atmosphere.

The vacuum of empty space is a restless place. Paul Schatzkin, Defying Gravity: NASA has done a study of this technology, and this technology is actually pretty good in very low browh environemnts. The lifter is essentially an open electrostatic ion engine, using the atmosphere or solar wind as a working medium.

The effect of inhomogenous electric fields i. Other ionic US patents of interest: It seemed to me that it generated more lift than effdct be generated by the ionic wind it developed, but it may have been electrostatically repelled from the carpeting as well.

From Wikipedia, the free encyclopedia. VP of International Spaceflight Museum – http: He found that virtual photons traveling through the material would have a strange asymmetry.

From the 1st of Feb.

The reduction in force is also a product of the reducing breakdown voltage of air, as a lower potential must be applied between the electrodes, thereby reducing the force dictated by Coulomb’s Law. Email required Address never made public. Found this in the links that Redsky posted. This implies that the quantum vacuum is the seat of something in motion whenever static fields are set up with non-vanishing Poynting vector, as Maxwell and Poynting foresaw.

Initial analyses favor a direct correlation between the sample masses and the differential signals. I think we’ve gota case of cross purposes here There is even a limit to its thrust effectiveness: 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.


In fields ofvolts per meter and 17 tesla—which can be created in the lab—the material should move at a rate of 50 nanometers per second, Feigel says, which should be measurable.

I concede that the thinner the vacuum, the lower the thrust, that is a given, but nor is this dependent on any crazy physics either: Common to positive results is that the force observed is small in comparison to experiments conducted at standard pressure. However, this effect works using either polarity for the electrodes: 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.

In a series of papers co-authored with fellow university physicist Douglas G. Campbell pointed out to a Wired magazine reporter that creating a true vacuum similar to space for the test requires tens of thousands of dollars in equipment.

Brown believed that his large, high voltage, high capacity capacitors produced an electric field strong enough to marginally interacted with the Earth’s gravitational pull, a phenomenon he labeled electrogravitics.

Biefeld-Brown effect Lifter

The whole apparatus is setup in an underground chamber below a large climate controlled laboratory. Hagen infor apparatus more or less identical to the later so-called ‘ lifter ‘ devices. A light balsa frame, aluminum foil, some wires, and 30, volts will make a levitating model craft for which no clear explanation exists for that behavior.

Leave a Reply Cancel reply Enter your comment here He called it an “ionocraft”. Additionally, I wonder how it compares to closed case ion drives, lets say if you injected some propellant into the electrostatic field How should one define the momentum of an electromagnetic field permeating matter?


As air pressure is removed from the system, several effects combine to reduce the force and momentum available to the system. Given internal ion engines need efect near vacuum to work in as well, the only difference is that a lifter could theoretically use the proton flow of the solar wind if its electrostatic field could be strong and large enough much like the magnetoplasma sail depends on solar wind as well.

You are commenting using your Twitter account. The test masses are spheres of equal sizes but different density hence different masses. By now, many ecfect are familiar with the idea that the vacuum contains energy — in fact a great deal of it — and that some can be extracted to do physical work. This page was last edited on 13 Decemberat Patent 3, — was granted to G.

Both do exert pressure but the radiation part is orders of magnitude more powerful. Latest Solar Wind Values Thrust gets extremely small at LEO atmospheric densities, even at the relatively low voltages NASA tested 10kk voltswhich is considered low. Based on an analysis of experimental data taken on the Biefeld-Brown effect, a case is made for describing this effect as a secondary electrostatic effect related to the global electric field.

Rffect observed changes in angular momentum agree with the classical theory. As for the maser lightcraft, I’d never heard of it, sounds interesting, do you have any more info on this?

The effect is generally believed to rely on corona dischargewhich allows air molecules to become ionized near sharp points and edges.

InBrown filed a patent that claimed that a net force on the asymmetric capacitor can exist even in a vacuum.

Biefeld–Brown effect

Talley conducted a test on a Biefeld—Brown-style capacitor to replicate the effect in a vrown. Instead, they proposed that the Biefeld—Brown effect may be better explained using ion drift instead of ion wind due to how the former involves collisions instead of ballistic trajectories. Brown filed another patent in that detailed the physics of the Biefeld—Brown effect, making the following claims:
