Nautilus (Verne) sea monster not yet known to science. To submerge deeply in a short time, "Nautilus" uses a technique called "hydroplaning", in which the vessel dives down at a steep angle. "Nautilus" supports a crew that gathers and farms food from the sea. "Nautilus" includes a galley for preparing these foods, which includes a machine that makes drinking water from seawater through distillation.
