Reappeared information on successful experiments for NASA's impossible in terms of today's physics engine EmDrive, invented by Roger Schoyer (Roger Shawyer). The main components of this engine magnetron oscillator and a high quality factor. According to the creator of this engine, the working draft is created by oscillation of microwaves, which repel the inner walls of the closed metal container. This concept is totally contrary to the law of conservation of momentum.
However, NASASpaceflight published data from tests of this engine in a vacuum. Results are in the range of 50 to 900 millinewtons, and there is a strong trend to increase traction with increasing feed energy. Creator of EmDrive is estimated that it is possible to create superconducting cosmic version of the engine that can deliver thrust of 300 Newtons per kilowatt of electricity produced by a compact nuclear reactor. In this power source it is possible to create an unmanned space probe, which can reach the system Alpha Centauri for 10 years.
To provide thrust of 300 Newtons per kilowatt is necessary to increase the proportion of energy supplied to thrust not inconsiderable 300 times. Tested by NASA prototype creates a real static thrust, but the project is ridiculed by almost the entire scientific community. In the prototype using 12 KW magnetron with water cooling. There were 134 test and so far has registered a maximum thrust of 214 millinewtons per kilowatt. The questions are many, but it is possible this be the future of the Earth spacecraft.
