Among the theoretical explanations he provides there are A Note on the Principles of EmDrive force measurement Principle of Operation Theory paper None of these appear to be peer-reviewed. (ii) NWPU group Applying Method of Reference 2 to Effectively Calculating ...

the video show that the principle of helicopter works in a zero-g (no gravity) environnement, not that the principle works in space. The helicopter is able to lift on earth (and int the space shuttle) because of the viscosity of the air. Whitout any friction, there is no move. In space, there is really few particles. So the friction would be very low and ...

It sounds like what you're looking for in general is an SSTO (Single Stage To Orbit -- http://en.wikipedia.org/wiki/Single-stage-to-orbit -- meaning it doesn't drop off boosters on the way up) rocket with a high payload fraction ( http://en.wikipedia.org/wiki/Payload_fraction -- meaning most of the spacecraft isn't fuel and fuel tank). Unfortunately, ...

The answer based on accepted physics is trivial: none. That's why they call it science FICTION. One can theoretically reduce the amount of propellant, but then the required power these ships would have to develop would go trough the roof. Keep in mind that a medium sized rocket develops on the order of 10GW of power for a few minutes during first stage burn ...
