Biefeld-Brown effect is not understood. The order of magnitude of the net force on the asymmetric capacitor is estimated assuming two different mechanisms of. PDF | The Biefeld-Brown is a fascinating effect with which levitation can be reached without moving or rotating elements. Static voltage is. Biefeld-Brown effect Lifter. «on: 03/15/ AM». Has anyone heard of (or even built) one of these asymmetrical capacitor “Lifters”. I just saw a story on it.

The thruster would be thrusting in the direction of travel in orbit, not vertically. Unlike the Casimir effect, which is insensitive to the ultraviolet cut-off needed to make summations and integrals converge, this new effect depends critically upon high-frequency and is, in this sense, more like the Lamb shift.

There is even a limit to its thrust effectiveness: Propulsion Physical phenomena Anti-gravity. Fill in your details below or click an icon to log in: A theoretical derivation of this force has been proposed see the external links below. 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: Other ionic US patents of interest: Several researchers claim that conventional physics cannot adequately explain the phenomenon.

It might be useful as a thruster in LEO, where there is still some atmosphere, but less effective the higher in the thermosphere you get. To get to higher speeds, you need biefelld operate this at higher voltages.

Thrust gets extremely small at LEO atmospheric densities, even at the relatively low voltages NASA tested 10kk voltswhich is considered low. The test masses are gold-coated metal spheres, electrically isolated and suspended between the electrodes of the capacitor. In fields ofvolts per meter and 17 tesla—which can be created in the lab—the material should move at a rate of 50 biefwld per second, Feigel says, which should be measurable. Retrieved from ” https: From Wikipedia, the free encyclopedia.

Historically, numerous patents have been granted for various applications of the effect, from electrostatic dust precipitation, to air ionizersand also for flight. Look its this simple: Usually, two electrodes are used with a high voltage between them, ranging from a few kilovolts fefect up to megavolt levels, where one electrode is small or sharp, and the other larger and smoother.

As part of a study inU.

With a large enough power supply, it shouldn’t matter how little thrust this produces, so long as it produces even a miniscule thrust: Talley conducted a test on a Biefeld—Brown-style capacitor to replicate the effect in a vacuum. It seemed to me that effcet generated more lift biegeld could be generated by the ionic wind it developed, but it may have been electrostatically repelled from the carpeting as well. 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 eeffect this case too needs to be very light.



Below the glow discharge region, the breakdown voltage increases again, whilst the number of potential ions decreases, and the chance of impact lowers. Anyway, here are some links: Brown filed another patent in that detailed the physics of the Biefeld—Brown effect, making the following claims: The brrown 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.

He called it an “ionocraft”. This creates a high field gradient around the smaller, positively charged electrode.

In his patent titled “Electrokinetic Apparatus,” Brown refers to electrokinesis to describe the Biefeld—Brown effect, linking the phenomenon to the field of electrohydrodynamics EHD.

Biefeld–Brown effect

Hagen infor apparatus more or less identical to the later so-called ‘ egfect ‘ devices. Built the HV power supply from plans and parts from Information Unlimited, and rigged it up with a joystick so it was maneuverable around the room though it had an umbilical for the power.

Found this in the links that Redsky posted. 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.
