Actually, they did. On http://www.emdrive.com/ they say "No propellant
is used in the conversion process". In the previously linked page
there was the example of a satellite that needs 1.7 tons of
propellant, which wouldn't be required with their drive.

So it's a perpetual motion machine, which happens to be reactionless.
The best of both worlds :-)
