To be honest, I thought this was a complete meme and it was never going to happen, but this is really crazy. It could absolutely change the way we transport things. Like I mean, flying cars, moon bases, no energy crisis, etc. Now, of course, this is in the very early stages, and all of those things are in the very optimistic case, but science is in a very exciting place right now. [quote]The EmDrive is the invention of British scientist Roger Shawyer, who proposed in 1999 that based on the theory of special relativity, electricity converted into microwaves and fired within a closed cone-shaped cavity causes the microwave particles to exert more force on the flat surface at the large end of the cone (i.e. there is less combined particle momentum at the narrow end due to a reduction in group particle velocity), thereby generating thrust. His critics say that according to the law of conservation of momentum, his theory cannot work as in order for a thruster to gain momentum in one direction, a propellant must be expelled in the opposite direction, and the EmDrive is a closed system. However, Shawyer claims that following fundamental physics involving the theory of special relativity, the EmDrive does in fact preserve the law of conservation of momentum and energy.[/quote] Also, for anyone who doesn't know what any of this means, the picture above is a pretty solid explanation for the layman.
