This is an interesting development. Fundamental questions need to be answered like how much thrust could be produced by this type of engine? Such engines could be highly useful for the realization of space colonization. There is however the necessary critique on the research method of NASA, which you can find at http://blogs.discovermagazine.com/outthere/2014/08/06/nasa-validate-imposible-space-drive-word/
Roger Shawyer is one of the most persistent and driven individuals in the world.
For years, he has been working on a new type of propulsion engine that could theoretically run forever without needing any fuel. He calls his device the EmDrive.
The engine works by bouncing around microwave radiation in a small space to produce thrust, rather than burning a propellant fuel. The microwaves are produced by solar power which is generated from panels on the outside of the engine.
When he first began proposing the idea for a quantum vacuum plasma thruster, Shawyer was laughed at. Most scientists he talked to told him the idea was ludicrous, saying that (among other issues) it defied the theory of conservation of momentum.
Only a group of Chinese scientists was willing to actually try…
