^^ I would say that greatly depends on the details. If you put in electricity and got out a controlled gravitational force, then yes. But if it requires a whole lot of M/AM plasma, then no.
The 23rd century can afford to feed its gizmos in ways we can not.
Of course, that's just as true for replicators, holodecs and what ever else.
Interesting question: if you put in a kilowatt of power and the gave plate converts this at, say, 0.1% efficiency, what units would you measure the field in? Newtons? Newtons per second? Newton-meters per second?
