Does "EmDrive" quantum effect produce thrust, in violation of Newton's Third Law?

[QUOTE="freyar, post: 6384739, member: 40227"] I haven't watched MythBusters, so I can't really answer that with personal experience. My admittedly second- or third-hand understanding is that MythBusters is showing people that they can think about and test claims critically, even if in a non-rigorous way. That's great! It's an introduction to the scientific mindset. That's vastly different than claiming to produce quantitative scientific research. That's fine, but we'd be in bad shape if someone didn't come along behind him and do the work in a scientific way --- we'd end up like pakleds from TNG. The answers to your questions are a) We have no data from experiments that can be expected to provide results sensitive enough to tell. If EmDrive worked, it would violate not just an empirical law of physics but a mathematical theorem, so it would be indeed amazing. b) With extreme certainty, I would say we are paying $100 for 0 thrust. This kind of machine comes up now and again --- it seems like you could make a perpetual motion machine out of one of these, and perpetual motion machines are a dime a dozen. But none of them work (and the US Patent Office has a policy against granting patents to them, when it remembers to follow it). c) Unless you want to be a pakled, this is not just an academic question....
