The first design of a resonant cavity thruster claiming to be a reactionless drive was by Roger Shawyer in 2001. He called his conical design an "EmDrive", and claimed that it produced thrust in the direction of the base of the cone. Guido Fetta later built a "Cannae Drive", based in part on Shawyer's concept, [18] [17] using a pillbox-shaped ...
In a review of Google Drive after its launch in April 2012, Dan Grabham of TechRadar wrote that the integration of Google Docs into Google Drive was "a bit confusing", mainly due to the differences in the user interfaces between the two, where Drive offers a "My Drive" section with a specific "Shared with me" view for shared documents. He ...
The thrust estimates published in that work, however, were subsequently shown to be almost nine times theoretically possible levels even if 100% of the input microwave power were converted to thrust. [9] Ad Astra Rocket Company is developing the VASIMR. Canadian company Nautel is producing the 200 kW RF generators required to ionize the propellant.
A reactionless drive is a hypothetical device producing motion without the exhaust of a propellant.A propellantless drive is not necessarily reactionless when it constitutes an open system interacting with external fields; but a reactionless drive is a particular case of a propellantless drive that is a closed system, presumably in contradiction with the law of conservation of momentum.
The Z-drive is so named because of the appearance (in cross section) of the mechanical driveshaft or transmission configuration used to connect the mechanically supplied driving energy to the Z-drive azimuth thruster device. This form of power transmission is called a Z-drive because the rotary motion has to make two right angle turns, thus ...

According to Ad Astra as of 2015, the VX-200 engine requires 200 kW electrical power to produce 5 N of thrust, or 40 kW/N. [6] In contrast, the conventional NEXT ion thruster produces 0.327 N with only 7.7 kW, or 24 kW/N. [6] Electrically speaking, NEXT is almost twice as efficient, and successfully completed a 48,000 hours (5.5 years) test in ...
