CEAS 2009: The Emdrive spaceplane

Electromagnetic drive, huh. Maybe they can help Mr. Moller finish his aircar before they move on to the heavens.

The EmDrive is generally considered to be in the same crackpot fringe as perpetual motion and free energy devices. Every reputable scientist who has commented on it believes it doesn't work.

The EmDrive, if it worked, would violate conservation of momentum, which is a fundamental principal of physics that every theory of physics that is accepted or seriously considered by the mainstream scientific community obeys.

The EmDrive's designer claims a theory of operation based on commonly accepted physical principals. But all of those physical principals have been mathematically proven to always conserve momentum. So the EmDrive designer's calculations have to be in error. The only way a reactionless drive could possibly work would be through principals of physics that are unknown to science, and the EmDrive's creator claims no such principals.

Please see the Wikipedia article entitled "EmDrive" for more details.

The whole Emdrive propulsion concept is technically questionable. So if Emdrive is the "enabling" technology for this vehicle, it doesn't sound too promising.

After doing a bit of reading online about the Emdrive, it looks, if I may use the British term, like a load of codswallop.
