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

• 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

Scientists in China claim they’ve created a working prototype of the ‘impossible’ reactionless engine – and they say they’re already testing it in orbit aboard the Tiangong-2 space laboratory.

The radical, fuel-free EmDrive recently stirred up controversy after a paper published by a team of NASA researchers appeared to show they’d successfully built the technology.

If the physics-defying concept is brought to reality, it’s said the engine could get humans to Mars in just 10 weeks.

But now, scientists with the China Academy of Space Technology claim NASA’s results ‘re-confirm’ what they’d already achieved, and have plans to implement it in satellites ‘as quickly as possible.’

With no fuel to eject, the EmDrive would violate Newton’s third law, which states that for every action, there is an equal and opposite reaction.

At a press conference in Beijing, however, researchers with Cast confirmed the government has been funding research into the technology since 2010, and claimed they’ve developed a device that’s already being tested in low-Earth orbit, IBTimes UK reports.

It comes just a month after anonymous sources told IBTimes UK that tests on the EmDrive were underway aboard Tiangong-2.

‘National research institutions in recent years have carried out a series of long-term, repeated tests on the EmDrive,’ Dr Chen Yue, head of the communication satellite division at Cast said at the press conference, IBTimes UK reports.

‘NASA’s published test results can be said to re-confirm the technology. We have successfully developed several specifications of multiple prototype principles.

‘The establishment of an experimental verification platform to complete the milli-level micro thrust measurement test, as well as several years of repeated experiments and investigations into corresponding interference factors, confirm that in this type of thruster, thrust exists.’

Cast is a subsidiary of the Chinese Aerospace Science and Technology Corporation (CASC) and the manufacturer of Dong Fang Hong satellites.

According to Li Feng, chief designer of Cast’s communication satellite division, the team has built a prototype that so far generates just a few millinewtons of thrust, IBTimes UK reports.

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.

China will leave the US in the dust in basically every area.
