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) six, to be provisioned for 20 days at sea. The upper surface was provided with 30 "carcass" compartments. The hull was to imitate a sea-going sloop with conventional-looking mast and sails that could be lowered and unstepped for submersion. Her two-bladed propeller, still hand-cranked, folded up out of the water when surfaced to reduce drag. When submerged, air came through two streamlined ventilation pipes, and light from the conning tower. However, none of this was actually constructed. Nautilus (1800 submarine) Nautilus was a submarine first tested in 1800. Though preceded by Cornelis Drebbel's vessel of 1620, "Nautilus" is often considered
