The em drive is a 'reactionless' drive that uses a resonant microwave chamber to 'somehow' develop a propulsive force from some mojo in the qantum vacuum. The principle is explained here Emdrive - Theory - Principle of Operation, although the exact physics is not understood. The RF resonant cavity thrusterwas invented by British aerospace engineer Roger J. Shawyer. The device uses a magnetron to produce microwaves for thrust, has no moving parts and needs no reaction mass for fuel. Both NASA and Chinese labs (perhaps others) have been able to build devices that replicate the effect. At present it only produces a tiny amount of thrust, but it does seem to be able the replicated.
A drive that doesn't need propellant and can be run for long periods of time would be perfect for an in system drive, and while the current devices are a long way from a practical drive it is perhaps the most hopeful approach yet for exploring the solar system.
During some laser Interferometry tests of the drive NASA recently found some evidence to suggest that the some of the laser light may have travelled faster than light in some parts of the resonant chamber. One explanation for this could be the generation of a warp bubble, and this would be the most exciting development in space propulsion. It could be NASA having a 'cold fusion' moment and there are any number of technical errors producing the result.
