    The chances are it will eventually be found to be spurious, once NASA can cobble the cash together to test it properly. That they're not taking it seriously enough to be able to raise the funding to do so, tells you all you need to know really.

    But reddit said it could be creating a warp field...

    Exceptional claims require exceptional proof.

    Given the amount of power involved I'd be shocked if there wasn't some interaction with the test setup.

    A Cookes Radiometer will whizz around in sunlight and that's just a few hundred watts/square meter.

    2.5Kw of microwaves ( 2.45GHz isn't WiFi friendly) and they measured 720mN
    or the same as a weight of 0.073mg

    It is indeed rubbish. More specifically, the notion that it propels itself by violating Newton's 3rd law, or by exploiting the quantum vacuum, is rubbish.

    The device itself is interesting insofar as it teaches us important lessons about accounting for variables in lab experiments. It is in the same category as the recent experiment in Europe that originally detected neutrinos travelling faster than the speed of light.
