Reading the paper, they still have a lot of trouble distinguishing a genuine thrust signal from a thermal expansion signal. I'm still betting on this thing not working and the signal being a measurement error.

That said, I am genuinely impressed with the work described in the paper, this is good experimental science and a lot of hard work.

Clearly no

III. Conclusions

...

Although this test campaign was not focused on optimizing performance and was more an exercise in existence proof, it is still useful to put the observed thrust-to-power figure of 1.2  mN/kW in context. The current state-of–the-art thrust to power for a Hall thruster is on the order of 60  mN/kW. This is an order of magnitude higher than the test article evaluated during the course of this vacuum campaign; however, for missions with very large delta-v requirements, having a propellant consumption rate of zero could offset the higher power requirements. The 1.2  mN/kW performance parameter is over two orders of magnitude higher than other forms of “zero-propellant” propulsion, such as light sails, laser propulsion, and photon rockets having thrust-to-power levels in the 3.33–6.67  μN/kW (or 0.0033–0.0067  mN/kW) range.

There's only one way to prove this thing works... get Musk to send one up.

The thrust is so ridiculously low that there's no way to know if it's working or not. And even if it produces thrust, chances are it's just going to be one of the many sources of measurement error, and not any "real" effect they're trying to prove the existence of.

I saw one really interesting analysis that talked about the supposed thrust to power ratio of this device. Remember for a second that photons have momentum, and a spotlight actually produces a tiny amount of thrust. Well, when you compare the thrust to power, the spotlight would supposedly produce more thrust per watt of input power than the em drive.

Imagine how much faster these technologies would happen if NASA wasn't forced to hire a bunch of useless purple haired dykes and niggers in the name of "diversity".

I love new EMDrive news. We should be researching the living shit out of it until either its proven to be an error,or gives up its mystical secrets,so it can be made better,more efficient.

The implications of this working are unimaginable.

That's basically what we're doing. And consistently, the results come up as "Well, we can't entirely rule out it's measurement error, but we're not quite sure it works either."

We also dont know why it works if it does,so we cant make a better one until we understand more. The person that stumbles upon the magic improvement(if there is one) will be richer than the guy who stumbled upon vulcanization of rubber.Knowing how fate generally rhymes,the supposed leap-forward will be something stupid,like filling the cavity with neon,or making the cavity a lopsided loop rather than a cone.

That costs money. If I remember there are 2 or 3 independent groups working on this. To fund another entirely independent group would cost ~5 million dollars and take ~10 years for them to get up to speed. You also have the problem that there are only so many places with equipment sensitive enough to test the EMdrive and building more of those is hard and costs money too. Finally, who else knows enough to do the research? The three groups I mentioned might be able to take one-two new students, train them and make them useful every year at best. Research is slow, we all have to just accept that.

It's a sympathetic wave pulse engine, the problem is scaling it up enough to be useful.

As far as it actually working or not, it's been replicated hundreds of times by home physicists... And china on their space station, but I take anything out of china with a grain of salt because they propagandize EVERYTHING.

If we're struggling to prove that the thing even works, how could we possibly use it in a practical application?

In 1944, we were struggling to prove that nuclear fission even worked. In July 1945, we had the first successful test, and in August, we bombed Hiroshima.

Does anyone know how many Sheboons worked out the (((Math))) to make this work?
