Hi Kibo,Was ist denn aber mit dem Gerät nach Shawyers Bauweise?
das hat auch Schub erzeugt, nach dem hier (EmDrive - Wikipedia, the free encyclopedia) zu urteilen:
NASA replication (EmDrive)
In July 2014, a NASA team at Eagleworks Laboratories, led by physicist Harold G. White, reported on an evaluation of a tapered resonant RF cavity similar to Shawyer's EmDrive, with positive results.[16]Testing was performed on a low-thrust torsion pendulum that is capable of detecting force at a single-digit micronewton level, within a sealed stainless steel vacuum chamber, but at ambient atmospheric pressure, because the RF power amplifierused an electrolytic capacitor not capable of operating in hard vacuum.
NASA's tests of the tapered RF cavity were conducted at very low power (50 times less than Shawyer's 2002 experiment and 150 times less than the Chinese 2010 experiment) but a net mean thrust over five runs was measured at 91.2 µN at 17 W of input power. A net peak thrust was recorded at 116 µN at the same power level.[16]
