"NASA scientists have been daydreaming about a new kind of rocket engine that could carry astronauts to Mars in 70 days without burning any fuel. Now, in a new paper published in the peer-reviewed Journal of Propulsion and Power, they say that it might really work.
The paper, written by astrophysicists at NASA's Eagleworks Laboratories, tested a electromagnetic propulsion system, or “EM drive,” that generates a small amount of thrust simply by bouncing microwaves around a cone-shaped copper chamber. No propellant goes in, no exhaust comes out, and yet, somehow, the engine can make things move.
If you think that news sounds too good to be true, you've got good instincts — it just might be. This “impossible” fuel-less engine appears to violate one of the fundamental laws of physics." Washpost
I look forward to the learned discussion to follow. pl
