NASA Confirms ‘Impossible’ Thruster Actually Works
7th September 2014
Shawyer’s engine provides thrust by “bouncing microwaves around in a closed chamber.” That’s it. There’s no need for a propellant of any kind like rocket fuel. When filled with resonating microwaves, the conical chamber of the thruster experiences a net thrust toward the wide end. These microwaves can be generated using electricity, which can be provided by solar energy. In theory, this means that the thruster can work forever, or at least until its hardware fails.

Now, American scientists at NASA have given the EmDrive a go, and once again confirmed that it actually works. The test results were presented on July 30 at the 50th Joint Propulsion Conference in Cleveland, Ohio, and astonishingly enough, they are positive. The team behind the drive still doesn’t know why it works, just that it does.
