Inventor Guido Fetta describes EMdrive related propellentless Cannae drive aka Q drive system

Guido Fetta describes created unbalanced electromagnetic forces within the chamber. Guido says summing the lorentz forces has a propellentless force.

Guido Fetta, inventor of the Emdrive related Q-Drive. Dr Fetta has taken down his Cannae web-site, but the Internet Archive has kindly preserved it. The Mail has confused Dr Fetta’s efforts with Eagleworks’s own. While Eagleworks tested his Drive, and others, the testing invalidated the specific hypothesis that Dr Fetta was assuming in his design. As the Eagleworks paper from last year noted, the Cannae-design Q-Drive had notches in the dielectric disk, while the ‘null’ test article did not. Both produced positive results, thus providing experimental data against Fetta’s specific hypothesis of how the drive creates thrust.

Fetta, an independent inventor with a background in chemical engineering, explains that the drive is a “superconducting resonating cavity.” An imbalance in the cavity, Fetta says, creates thrust.

Fetta had tested a superconducting version of the “Q-drive” or Cannae drive on 13 January 2011 several years prior to the Eagleworks test campaign. The RF resonant cavity was suspended inside a liquid helium-filled dewar. The weight of the cavity was monitored by load cells. Fetta theorized that when the device was activated and produced upward thrust, the load cells would detect the thrust as change in weight. When the Cannae drive was energized by sending 10.5 watt power pulses of 1047.335 MHz RF power into the resonant cavity there was a reduction in compressive force on the load cells consistent with thrust of 8-10 mN. The results have not been published in the scientific literature, but were posted on Cannae LLC’s website.

Roger Shawyer, Emdrive inventor, stated that the Cannae drive “operates along similar lines to EmDrive, except that its thrust is derived from a reduced reflection coefficient at one end plate,” which he says “degrades the Q resonance factor of the device and hence the level of thrust that can be obtained”
