Discussion Overview

The discussion revolves around the mechanisms by which asymmetric capacitors might achieve lift, specifically examining the Biefeld-Brown effect and related phenomena. Participants explore theoretical explanations and practical experiences related to this effect, questioning the underlying physics and the validity of claims surrounding it.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant questions how an asymmetric capacitor can lift its mass even with high voltage (60 kV), expressing skepticism about the mechanism being purely electrostatic.
  • Another participant claims to have built a functioning device that achieved lift in a vacuum, although they acknowledge that this may not convince skeptics.
  • Several participants reference the Biefeld-Brown effect and ionocraft as related concepts, suggesting that ion wind may be the primary mechanism at play.
  • One participant expresses doubt about the term "asymmetric capacitance," suggesting that the effect is simply due to ion wind rather than any exotic physics.
  • A later reply indicates a realization that the effect does not work in extremely low vacuum, which diminishes their interest in the topic.

Areas of Agreement / Disagreement

Participants express differing views on the mechanisms behind the lift produced by asymmetric capacitors, with some supporting the idea of ion wind while others remain skeptical about the explanations provided. No consensus is reached regarding the validity of the claims or the underlying physics.

Contextual Notes

Participants note limitations in understanding the effect, including the dependence on vacuum conditions and the ambiguity surrounding the term "asymmetric capacitance." There are unresolved questions about the nature of the forces involved and the validity of anecdotal claims.

Yes, I know it is not anti gravity, but what mechanism do you think causes it. Could someone theoretically show me how an asymmetric capacitor can overpower its mass even with something like 60 keV between the conductors. I just don't see how a capacitor lifts off the ground no matter what voltage I put between the plates. I don't think it is something exotic like a Casimir effect, but what is it, pure electrostatics?

Sorry, I meant to say 60 kV, sixty thousand volts. To anyone doubting that these things work, I have built one and it did fly, even in a vacuum. I know that's little in the way of convincing to someone who might think I'm a quack.

No, I'm not even sure the term "asymmetric capacitance" has any meaning. This is simple ion wind that propells these things.

(It isn't a good idea to trust the explanation of someone who think's they've found anti-gravity)

I haven't been involved with this effect very much, but I remember encountering it in the internet. I suppose it's all about these things: http://en.wikipedia.org/wiki/Ionocraft http://en.wikipedia.org/wiki/Biefeld-Brown_effect

Some more or less cool photos about the topic: http://www.guns.connect.fi/innoplaza/energy/plasma/lifter/corona.jpg http://www.guns.connect.fi/innoplaza/energy/plasma/lifter/detail.jpg

Thanks, this is all I needed. My curiosity has been quenched when I realized this thing doesn't work in extremely low vacuum. The only thing I found interesting about it was that it worked in vacuum, but now that it appears it only works in weak vacuum all my interest has disappeared.
