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. "Nautilus" is not able to refresh its air supply, so Captain Nemo designed it to do this by surfacing and exchanging stale air for fresh, much like a whale. "Nautilus" is capable of extended voyages without refuelling or
Nautilus (1800 submarine) proposal to the Minister of Marine, who granted him permission to build. Fulton built the first "Nautilus" of copper sheets over iron ribs at the Perrier boatyard in Rouen. It was long and in the beam. Propulsion was provided by a hand-cranked screw propeller. The hollow iron keel was the vessel's ballast tank, flooded and emptied to change buoyancy. Two horizontal fins, diving planes in modern terms, on the stubby horizontal rudder controlled angle of dive. Overall, "Nautilus" resembled a modern research submarine, such as the NR-1, having a long teardrop hull. The design included an observation dome, somewhat similar
