Id love to see the big drives and gears on those huge freight ships! I bet they are massive. Ive seen the TV show where they detailed the building of a aircraft carrier and the size of things is just crazy, and they only need re-fueling every 25-30 yrs!! How is that even possible? since they are pretty much always on the move? Would the Govt have an energy technology that is super economical that they will not share with us..Gee I wonder!
