(and note, Q-thruster is basically just a resonant cavity tuned to a specific RF modulation mode, that contains a dialectric element. The Q-thruster IS an Emdrive, but not all Emdrive designs are Q-thrusters.)
Quantum Vacuum Plasma Thrusters
are different from RF Resonant Cavity Thrusters, though, with different (proposed) mechanisms behind their 'creation' of momentum. (The first allegedly creates and ejects reaction-mass from virtual particles, thus getting around the need for a 'reaction mass' supply, the second involves unequal radiation pressures at each end of a chamber, thus getting around the need for
any reaction mass.)
Unless somebody is deliberately conflating it all into one confusing mess, which it increasingly sounds like they are...
I probably should wait until someone can come up with a half-decent theory (that explains
which effect they're actually trying to use), rather than inventing something just a hop-and-a-skip away from a Perpetual Motion engine (let's call it a PME of the zeroeth kind, as nobody is claiming actual inputless-perpetuity or the creation of energy from nothing,
a la PMEs of the first and second kind, merely creation of momentum-change from nothing) and trying to work out what it
isn't doing, out of so many possibilities, one theory at a time. That's just too slapdash, whatever the budget and engineering difficulty behind it all...
