Who needs the laws of physics, anyway?
Not NASA. At least, that is what a new peer-reviewed paper indicates. The paper discusses what was a fuel-free rocket engine, which tests now show works. But how does it work? And what does this mean for the future of space travel?
In IT Blogwatch, we are ready for liftoff.
Want to know what exactly this new type of rocket engine is? Sarah Kaplan has the background:
NASA scientists have been daydreaming about a new…rocket engine that could carry astronauts to Mars in 70 days without burning any fuel. Now, in a new paper…they say that it might really work…The paper…tested a electromagnetic propulsion system, or “EM drive.”
The idea for an EM drive was first published a decade ago by British engineer Roger Shawyer. He argued that…the thrust comes from radiation pressure. Microwaves inside the cavity create an imbalance of radiation that pushes against the walls and generates thrust.
So why is an EM drive important? Trent Moore explains:
