I've watched the show for years, but I'm going through the whole series right now. A thought came to me. What powers the saucer section when it's separated from the starboard section? Engineering and the engine is in starboard. So, starboard can be powered by that. But is there a secondary, smaller engine for the saucer? If so, would there be a secondary engine room somewhere in the saucer section? If it does have its own engine for seperation purposes, would it have as much power as the main engine? Would it have to recharge (or whatever) more often? Can the saucer go to warp on its own?
