If the EmDrive worked, you'd still need rockets to lift you into space. The EmDrive isn't projected to scale to ever be a launch system, nor even to get out of Earth's gravity well. Once out far enough, however; if calculations are correct, it was be cheaper than an Ion Thruster given enough time.

Unless performance drops with speed you can't escape WMD potentials should these drives have useful thrust.

Any useful tool is equally useful as a weapon.

Woodward and Fearn's Mach Effect work is demonstrably real (having been duplicated by three independent labs) and the EMDrive is not quite as real. The big question now is if the thrust can be scaled upto 1 G or more. If so, rockets and airplanes go away and are replaced by "flying vehicles". If not, we still have a great space drive for getting around the solar system, but will still need rockets for Earth to LEO launch. The Mach Effect equations suggest such scalability. The issue is materials. The colossal dielectric and electrostrictive material being developed would be necessary. Since the Mach Effect is essentially electro-mechanical at high voltages, materials life-times are a serious issue here.

Building a commercial device is engineering, an we've done similar engineering before. Piezo electric stuff an capacitors are known, and it will simply be a matter of time to get reliable systems.

Correct me if I am wrong, but my impression is that the [EDIT:- current, not original] thrust levels versus energy input is at least a million times less than originally claimed based on the more recent test results margins for error. As such, even if the physics works, thrust will be much less than even current ion thrusters per input energy amount (admittedly needed reaction mass may be less). As such, acceleration would be very slow and time to a target would be prolonged compared to even ion thrusters with their reaction mass included.

Theoretically, acceleration to interstellar speeds (say 20% the speed of light) might be possible with a fusion reactor providing the power. But if it takes you a thousand years to reach that speed it is not useful.

I don't know about em drive, but as I recall, Mach effect has a couple of orders of magnitude of improvement available from better materials, drivers, etc. That can be had.

I recall they were limited in how high they could drive both in frequency and power, both of which would boost thrust. They were also looking at capacitance materials with higher values, K I think was the letter they used. That and frequency were supposed to scale exponentially as I recall.
