Part of the several hundred tonnes associated with the "CV" margin is set aside for a couple of steam plants, condensers and distilled water plants. Too late for Lizzy, but with the way things are, still just about possible for PoW. Of course, whether the capacity of these plants would be enough to feed a C-13 (or BS6.....) at a rate sufficient to launch every minute is another question.....as is whether we could re-establish a steam module in the engineering courses, or accommodate the required clankies aboard ship.
