China built NASA's utopian engine

A version of a fuel-free engine is considered "impossible" in physics, successfully tested by Chinese scientists.

Scientists at the China Aerospace Technology Academy say the engine version called EmDrive is being tested in the Earth Orb 2 space station lab, Popular Science, on December 19. believe.

The idea of ​​making an EmDrive engine without fuel or any of the traditional rocket launchers inside could bring people to Mars within 10 weeks, thought to be "unimaginable" or " unimaginable" by many scholars. Feasibility".

In fact, without using fuel, an engine could not work because it was contrary to Newton's Rule 3 . The law proposed by physicist Isaac Newton confirms that the force does not appear separately but appears in pairs of forces - jets. In other words, force only appears when there is interaction between two or more objects and the pair of forces is the same but opposite.

However, during a seminar in Beijing, experts from Cast, a subsidiary of China Aerospace Science Corporation (CASC), announced that the Chinese government subsidized technology research. Since 2010 and the device they developed is being tested on Earth's low orbit.

"In recent years, research institutes have conducted long-term tests on EmDrive. Test results published by NASA in November confirmed the existence of this technology. We have successfully developed. some engine models, " said Dr. Chen Yue, head of Satellite communications at Cast.

"We do a lot of experiments to complete the propulsion on a micro scale, as well as go through a few years' process to find out the influencing factors. We can confirm that this kind of motivation can still be active in the universe ".

However, according to Cast's design director Li Feng, their engine version created thrust of a few milinewtons. To work on satellites, the repulsive force must reach about 0.1-1 Newton."This technology is entering the next phase, with the aim of applying it to current satellites as quickly as possible. Despite many difficulties, we are confident that we can do it," Li Feng said.

The EmDrive engine uses completely solar energy to create thrust by allowing the microwave to repeatedly hit the wall of the chamber. It has the ability to increase velocity to 9.4% of the speed of light, meaning it can fly to Mars within 70 days, to Alpha Centauri star system 4.37 light-years from Earth after 92 years, according to NASA.

The idea of ​​this engine was first introduced by British researcher Roger Shawyer in 1993. Four independent laboratories have studied this idea, including the US Aerospace Agency (NASA). NASA's Eagleworks team has announced that it will launch the EmDrive engine design in December 2016.
