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?
