preposterous bullshite or potential breakthrough?

what’s missing from this picture? yes, that’s right, the huge ground-cloud from some good ol’ fashioned newtonian friendly thrust. roger shawyer, managing director of the u.k.‘s satellite propulsion research (spr ltd.), has been trying for a few years now to side step the need for such massive raw thrust with tests on a prototype of what could possibly be the worlds first true reactionless drive, called the emdrive. the prototype has been greeted with much

skepticism, reactionless drives essentially being akin to that historical mainstay of quackery- perpetual motion machines. shawyer is not your average backyard junk-heap inventor and though the emdrive completely violates newton’s third law the math of the emdrive’s microwave propulsion is evidently o.k. and the prototype is actually producing thrust. pretty interesting. for more detail on the science check out the stories at eureka and the engineer. what do you think? path to anti-grav volkswagens or more poundage on the dookie pile?
