Twenty Thousand Leagues Under the Seas
The Nautilus remains underwater for months, powered by electricity and supplied almost entirely from the sea. Nemo uses it to abandon life on land.
The Abraham Lincoln encounters the Nautilus.
The chase begins in the western Pacific east of Japan. Aronnax, Conseil and Ned Land are taken aboard the vessel they had mistaken for a sea monster.

How close was the Nautilus to a real submarine?
Verne specifies a complete submarine: double hull, ballast tanks, diving planes, screw propulsion, electric lighting, and a pressure-resistant observation salon.
Fact-check
Nemo’s battery is the missing invention
Less than twenty years later, the all-electric Gymnote carried an eleven-ton battery and traveled only tens of miles underwater. Nemo’s sodium-from-seawater cells require an energy source the ocean cannot provide for free.

Original plates and later editions show how each generation pictured the same journey.
