20000 Leagues Under The Sea, by Jules Verne.
The story of Captain Nemo and his incredible underwater machine, the Nautilus. A submarine of considerable modern content (mysterious secret power plants, able to sustain underwater travel for extraordinarily long periods of time, complete living quarters, etc.), the Nautilus is Nemo s chief weapon in the war against Slaver s plying the African nations for their trade. This work was also popularized by Walt Disney Studios, bringing a rich color view of Verne s machines. Nemo while being a bit crazy is never-the-less a visionary both in terms of certain moralities as well as, of course, in his scientific discoveries and application to the underwater realm.
