No, German Scientists Have Not Confirmed the “Impossible” EMDrive

Some numbers to compare:

They got 20uN with a 700W magneton, that is 20uN/700W = 0.03 mN/KW. (Probably some energy is "lost" and the "real" efficiency is higher, but when you claim to break the physics law the measurements must be foolproof.)

The maximal theoretical output of a device that don't break the currently accepted physics laws is 1/c = 0.0033 mN/KW. So this measurement is 10x bigger than the theoretical maximum.

The 18-month-to-Pluto calculation use 0.4 N/KW = 400 mN/KW, that is approximately one half of the maximum claim of any of this device family, but most experiments get much smaller results. The 0.4 N/KW is 130,000x bigger than the theoretical maximum and 13,000x bigger than what they got in this experiment. So if a device with the same output of this experiment, the trip to Pluto will be much longer.

(Disclaimer: Just to be clear, I think this is only an experimental error.)
