If humanity ever wants to truly explore the outer reaches of our solar system or travel to other stars, we’re going to have to build a better engine for our spacecraft. In fact, this engine will have to be so good that it will be capable of generating thrust without consuming propellant. That’s right: If we ever want a four-hour trip to the moon or a two-month trip to Mars, we’re going to need a rocket engine that doesn’t need rocket fuel.
This is the idea behind the radio frequency resonant cavity thruster—otherwise known as EmDrive—a theoretical reactionless engine powered by turning electricity into microwaves and bouncing them around a closed metal funnel.
The EmDrive has been dismissed as “[URL='http://www.space.com/29363-impossible-em-drive-space-engine-nasa.html']impossible” on more than one occasion because it appears to violate Newton’s Third Law of Motion, which states that for every action there is an equal and opposite reaction. But if a leaked NASA paper posted online last Saturday is to be believed, then not only are NASA scientists pursuing an EmDrive, but they actually made one that works......[/URL]
