Discussion Overview

The discussion revolves around the effectiveness of lifters in a vacuum environment, specifically questioning whether they can generate lift without atmospheric conditions. Participants explore various aspects of the phenomenon, including experimental setups and the underlying mechanisms involved.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • Some participants question whether lifters work in a vacuum, noting that opinions are divided on this issue.
  • There is a claim that Beifeld and Brown's experiments used symmetrical capacitors and still produced a force, although this is contested.
  • One participant suggests that while asymmetry may enhance the effect, it is not strictly necessary for lift to occur.
  • Another viewpoint indicates that ionization of copper at the anode could produce some force in a vacuum, albeit minimal, and highlights that many vacuum systems used in experiments may not be effective, allowing ion wind to still be generated.

Areas of Agreement / Disagreement

Participants express differing opinions on the functionality of lifters in a vacuum, with no consensus reached on whether they can effectively generate lift without atmospheric conditions. The discussion remains unresolved regarding the mechanisms at play.

Contextual Notes

There are limitations regarding the assumptions made about the experimental setups and the definitions of terms like "ion wind." The effectiveness of vacuum systems used in experiments is also questioned, but no definitive conclusions are drawn.

I'm sorry if you guys discuss this already but I need some clarification. The more I find out about this topic the more puzzling it becomes. Straighten this out for me. Thx

1) Does it actually works in vaccum? Many say yes and few say no.
2) When Beifeld and Brown did the experiment, they did not use asymetrical capacitor (meaning they use symtrical) and it still experience a force. Is this true?
3) If it not ion wind, what is?
 
Physics news on Phys.org
1) No. See 3)
2) I think asymmetry improves the effect but isn't necessary. I'm not sure, however.
3) Ion wind
 
you'll probably get some force in vacuum due to the ionization of copper at the anode, however it won't be much. Also if you notice most of the vacuum systems used in these experiments aren't very good, and as such the effect will still persist as ion wind an still be created.

it's a sad result :(
