So is it conceptually possible to imagine some kind of propulsive device being built using the reverse Casimir effect described in the article? Something that might have the propulsive power of an ion engine, where its not very powerful but can run constantly? I know next to nothing about the math behind this, other than a rough and overly simplified understanding of the physics outlines, so feel free to laugh at me with gusto.
