Lifter. Does it actually works in vaccum?

AI Thread Summary
The discussion centers on whether lifters work in a vacuum, with mixed opinions on their effectiveness. Some participants argue that lifters can generate force even in a vacuum, primarily due to ion wind effects, although the force is minimal. The original experiments by Beifeld and Brown used symmetrical capacitors, which still produced a force, suggesting that asymmetry may enhance but is not essential for the effect. Concerns are raised about the quality of vacuum systems used in these experiments, which may still allow for some ion wind generation. Overall, the consensus leans towards limited effectiveness of lifters in a vacuum, leading to disappointment among participants.

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?

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 :(
 
The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...
Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds? Best regards, DaTario
Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
