Anyone heard about this?

Here's the leaked NASA report: https://drive.google.com/file/d/0B7kgKi ... ktQlU/view

I haven't read it all due to my slow internet and I can't search anything but from what I can see, there is a potential flaw in the experiment in that it appears they didn't compensate for induced eddy currents from the microwaves induced in the copper cone. Magnetic field and all. Of course, It's pure speculation on my part but there was no mention of this in the discussion of possible other effects so could can not be ruled out.

Ages ago. :)

Edit: IIRC China is going to try it in orbit on a satellite. My guess is, the satellite will eventually be lost because the drive doesn't work; and we'll hear nothing until someone leaks the failure to the media.

Not sure why they would want to do that when ion drives are proven and provide orders of magnitude more thrust for the same power input.

Because this supposed EM Drive claims you need a lot less fuel. And fuel of course is weight.
