  1. All these schemes remind me the old saw of why a person running on a skateboard doesn’t get anywhere.
    Or treadmill if you prefer something easier to visualize.

    E fields are cool, but put a charge in motion within and you also get a B field. It’s called EM for a reason.

    If they can run the experiment that can levitate a 1 gram test article and show that it is not emitting any radiation (photon, charged particle or otherwise) then it might warrant the expense of an orbital mission.

    Methinks they’ve likely just developed a better mouse trap er, I mean, ion drive. Nothing wrong with that, but it isn’t reaction-less.

    1. SpaceX makes it cheap enough to warrant an orbital test even if the physics are not in alignment with current understanding.

  2. Know it is a new interview but didn’t you post about these guys in April? Maybe it’s time for a cognitive test.
    Not sure their any new details
