    Donít Be Surprised if EmDrive Experiments Never Work

    Every few years the “EmDrive”, a proposed method of generating rocket thrust without any exhaust, hits the news. Each time, everyone asks: could this be it? Could this be the technological leap to revolutionize spaceflight? Don’t hold your breath. Here’s the basic idea behind the EmDrive. You take a chamber with a funky shape (usually …

    Why would I be surprised that the Emdrive never works? That’s like being surprised perpetual motion machines never work. It is, rather, what should be expected.

    Because it’s the 2020s and all kinds of crazy things are happening. If somebody built a working perpetual motion device tomorrow I’d probably shrug and go “Well, it’s 2021, this may as well happen.”

    None of the crazy things happening violate the laws of physics. There have been violations of good standards of human behavior, and violations of the upward trend of progress. With the latter's bad events and outcomes being largely a consequence of the former's bad decision making.

    I don't understand why it doesn't wiggle. I'm very surprised that it doesn't at least wiggle. There has to be a lot of "noise issues" that have to be canceled or suppressed. Personally, I am a fan of an external force making the thing move. Or some currently unknown interaction like the vessel shedding material on the outside from activity on the inside. I think the second idea is really cool, but making a tiny rocket is the opposite of what they want.

    I'm not familiar with the technical specs of the Em non-drive. But I am told the attempts at replicating the supposed directional motion have failed.

    Oh, I would hope and expect the laws of physics to say consistent, I’m just saying that my level of certainty about anything is a bit less secure than it used to be.

    It's a gorgeous looking model, all copper and silver looking. But it does look like a bell shaped ion thruster with the end capped off. Many of the diagrams show the beams or particles bouncing around the interior, which strikes me as being a good diagram of a vibrating pail of water. Like a vibrating pail of water, it does stand to reason that you should be able to introduce forces that should make it wiggle and tip over in unexpected ways. Also like a pail of water, it's bad engine design. For the life of me, I can't figure out why it wouldn't move. That part seems pretty easy to me.
