How much input power would it take to generate enough drive force to propel a small spaceship? It appears we are speaking about many billions of watts under the present conditions. I assume that future developments will improve the performance, provided it is real.

They tested the Cannae version (as reported by Wired) -- 40 micronewton at 28W , but ALSO a "tapered" version, which is an emDrive -- 91 micronewton at 17W.
