Hate to break this to you, but light has a thrust. It's been known for ... like decades. Just shine a light out of your spacecraft and you got thrust.

Problem is, the retard that "invented" this claims not even light is used as a propellant. Supposedly the system is completely closed.

Preservation of momentum is an indisputable fact, so of course he would get a lot of flak. If his experiments show otherwise, he is more than certainly doing something wrong, likely as you suggest he is letting electromagnetic waves escape in one direction, creating thrust in the other.

But esacping light will not explain the numbers given. 2.5 kW of light only correspond to about 8µN thrust, not 720 mN.

This thing is quiet obviously either a hoax or based on some very stupid experimental errors, which explains why he is ridiculed by other scientists. The only question here is why the author of this article was not capable of identifying the mistake in the original experiment and make fun of it in this article. That's like science reporting 101.
