The claim is 1KW to hover 3 tones. In space it means 1G acceleration for 3 tones by 1KW. Observers in cabine with working emDrive in both cases (Earth/Space) experience 1G and should not distinguish where this 1G came from according to the "principle equivalency". However, claim states that acceleration increases the kinetic energy so thrust is going down thus, the observer in the cabin on the Earth continue experience 1G while, observer in the space-cabine does not experience 1G thus the author of emDrive discovered a way to violate the "principle equivalency". How emDrive may "know" when it should produce the thrust 1G and when it should not; it must feel the gravitational gradient ;o) so when emDrive in free fall and it is powered on it stops the fall and hovered, but when emDrive is in free fall in space it realises that it is wrong place to produce thrust thus, to keep its credibility it does not produce thrust, somehow it feels the presence of gravity...
