Wikipedia quote:
A research group at the Dresden University of Technology also tested a small EmDrive in a hard vacuum and reported predicted as well as unexpected thrusts.[10][14]

The actual, published, paper:
[tu-dresden.de]

Apparently their conclusion was 'We saw stuff, but we can point out possible areas of interference, so we can't draw any proper conclusions.'

They also point out repeatedly they aren't trying to replicate the original experiment for confirmation purposes, but to identify potential interferent elements -- a goal which they accomplised quite well apparently.


I refer back to my original point... I'm strongly reminded of the first time the 'airfoil' shape of a whing was introduced and nobody understood why it did what it did ;0
