You can't have it both ways. You call it a "drive", and claim that
it does what a normal reaction-mass "drive" does, namely cause a
stationary mass to move in a fixed direction. If you claim that it
does this without the usual reaction mass being sent in the other
direction, then what you are claiming it does violates conservation
of momentum, regardless of your claim otherwise. The amount of
energy used is irrelevant, and you know that.
I suspect it may indeed do something useful, but it cannot do what
its plain (but vague) description intends us to believe it does.
