China's development is based on the invention of a British engineer Roger Shayvera, whose home country ridiculed for pseudoscientific fraud. Engine creates a craving unusual way: without combustion and without any moving parts.
"EmDrive" is a closed conical container which resonate under the influence of microwave radiation and creates a craving with a wide side "nozzle".
Chinese prototype "EmDrive" compared to modern jet engines it is incredibly easy and cheap to manufacture
It is possible that the "hack" Roger Shayvera be a breakthrough, which will provide space and atmospheric technique entirely new stunningly efficient engine. This is actually "anti-gravity" — the guy in the air without the roar of jets and noise propellers. While EmDrive provides little traction, which is enough to break up a small satellite (which in principle is in itself a great achievement).
Shayver but believes that the use of superconductors will increase traction at times — including the possibility of the separation of spacecraft from the surface of the planet and out into orbit. By 2016, the engineer plans to build the first prototype on superconductors, which will in the long term to increase engine thrust thousands of times.
