China claims to have a working version of NASA's impossible engine orbiting the Earth - and will use it in satellites 'imminently' ~ Dec 21, 2016

A fuel-free engine, described as 'impossible' to create, may now be a step closer to reality, according to leaked Nasa documents. Pictured is a prototype of the EMDrive

• The scientists say they've created a working prototype and are testing in orbit
• They've revealed plans to implement it in satellites 'as quickly as possible'
• They say it is 'currently in the latter stages of the proof-of-principle phase'
• EmDrive creates thrust by bouncing microwaves around a chamber
• The system has caused a stir as it it 'goes against' the laws of physics

THE EMDRIVE
The concept of an EmDrive engine is relatively simple.
It provides thrust to a spacecraft by bouncing microwaves around in a closed container.
Solar energy provides the electricity to power the microwaves, which means that no propellant is needed.
The implications for this could be huge. For instance, current satellites could be half the size they are today without the need to carry fuel.
Humans could also travel further into space, generating their own propulsion on the way.
But when the concept was first proposed it was considered implausible because it went against the laws of physics.
Its allegedly fuel-free nature also means the drive may directly contradict the law of conservation of momentum.
It suggests it would produce a forward-facing force without an equal and opposite force acting in the other direction.
