Ma allora è vero che l'EmDrive funziona? Questo articolo di ricercatori

   A vacuum test campaign evaluating the impulsive thrust performance
   of a tapered radio-frequency test article excited in the transverse
   magnitude 212 mode at 1937 MHz has been completed. The test campaign
   consisted of a forward thrust phase and reverse thrust phase at
   less than 8 x 10^-6 torr vacuum with power scans at 40, 60, and 80W.
   The test campaign included a null thrust test effort to identify any
   mundane sources of impulsive thrust; however, none were identified.
   Thrust data from forward, reverse, and null suggested that the
   system was consistently performing with a thrust-to-power ratio
   of 1.2 ± 0.1 mN/kW.

Bye,
