China claims to have built working version of NASA's impossible engine

Dr. Chen Yue, Director of Commercial Satellite Technology for the China Academy of Space Technology (CAST) announced on December 10, 2016 that not only has China successfully tested EmDrives technology in its laboratories, but that a proof-of-concept is currently undergoing zero-g testing in orbit (according to the International Business Times, this test is taking place on the Tiangong 2 space station).

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

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.

At a press conference in Beijing, 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 shown below.

‘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.’

On November 20th, NASA's long-awaited EM Drive paper was peer-reviewed and published. And it showed that the 'impossible' propulsion system appears to work. Tests carried out by both NASA and independent researchers confirmed that the drive was able to produce thrust in a vacuum that would allow us to reach the moon in just four hours, Mars in 70 days, and Pluto in just 18 months.

The NASA Eagleworks Laboratory team in what is the first peer-reviewed research ever published on the EM Drive, lays out the hypothesis for how the EM Drive could produce thrust – something that would appear impossible according to our current understanding of the laws of physics.

The full and official peer-reviewed paper regarding the drive appeared online through the American Institute of Aeronautics and Astronautics (AIAA)’s Journal of Propulsion and Power. It's a big milestone, said Motherboard yesterday, "but keep in mind that peer-review doesn't mean the argument necessarily holds water, only that the measures taken to arrive at the conclusion were considered sound."

The EM Drive, or Electromagnetic Drive, is a propulsion system first proposed by British inventor Roger Shawyer back in 1999 based on the theory of special relativity, electricity converted into microwaves and fired within a truncated cone-shaped closed metal cavity causes the microwave particles to exert more force on the flat surface at the large end of the cone (there is less combined particle momentum at the narrow end due to a reduction in group particle velocity), generating thrust.
In order to minimise the internal Doppler shift (the change in frequency or wavelength of a wave for an observer moving relative to its source), circular polarisation and a phase-locked loop control the microwave input to the thruster, which maximises thrust as it accelerates.

Critics say that according to the Newton's law of conservation of momentum, EM Drive theory cannot work as in order for a thruster to gain momentum in one direction, a propellant must be expelled in the opposite direction, while the EmDrive is a closed system.

EM drive inventor, Roger 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. Instead of using heavy, inefficient rocket fuel, it bounces microwaves back and forth inside a cone-shaped metal cavity to generate thrust that it could power NASA to Mars in just 70 days.
