WebAugust 6th, 2014 - The story begins several years back with a British inventor named Roger Shawyer and his EmDrive a prototype rocket engine which he claimed generated thrust by bouncing microwaves around in an enclosed metal funnel National Geographic Magazine EmDrive In 2001, Shawyer founded Satellite Propulsion Research Ltd, to work on the EmDrive, which he said used a resonant cavity to produce thrust without propellant. The company was backed by a SMART award grant from the UK Department of Trade and Industry. In December 2002, he loosely described a prototype … See more The EmDrive is a concept for a thruster for spacecraft, first written about in 2001. It is purported to generate thrust by reflecting microwaves inside the device, in a way that would violate the law of conservation of momentum and … See more All proposed theories for how the EmDrive works violates the conservation of momentum, which states any interaction cannot have a net force; a consequence of the conservation of momentum is Newton's third law, where for every action there is an equal and … See more The strongest early result, from Yang's group in China, was later reported to be caused by an experimental error. Tajmar published an explanation of how all reports of apparent thrust could have been caused entirely by failing to account for all sources of error or … See more • Official website, Cannae • Official website, EmDrive • Oberhaus, Daniel (5 June 2024).
