A steam powered submarine: the IctĂneo
https://www.lowtechmagazine.com/2008/08/submarines-1.html
Few Victorian inventions have the grace and charm of the IctĂneo, the series of two wooden submarines built by NarcĂs Monturiol i Estarrol in the second half of the nineteenth century.
Unlike some of the better known early submarines from his contemporaries in Germany, France and the United States, the Catalan inventor managed to build submarines that operated flawlessly.
The IctĂneo II was the first combustion engine driven submarine ever, pioneering concepts that were only rivalled in the 1940s. Sadly, both submarines were eventually scrapped and Monturiol died penniless and forgotten.
Monturiol’s IctĂneo (derived from the Greek words for fish and for ship) was launched in 1859 in Barcelona harbour to instant success. Monturiol, who possessed no scientific education, became a local hero. The submarine, made of olive wood supported with oak rings and sheathed in two-millimetre thick copper, measured only 23 feet (7 meters) in length and offered hardly enough space for the captain and the four man crew who powered the ship by cranking.
Despite it's low-tech appearance, the IctĂneo was a marvel of sophisticated technology, decades ahead of its time. The vessel had a double hull - a spherical inner shell that resisted the water pressure, and an outer fish-like shell that protected the submarine and was used for steerage and hydrodynamics.
Between both hulls were four ballast tanks, controlled from within the cabin by valves letting in water or forcing in air. During driving, pitch was controlled by a weight which could be moved along a rail. This micromanagement of buoyancy allowed the IctĂneo to remain at extremely precise depths - a feat which other submarines at that time could not achieve.
Hyper-Sub - Diver Delivery Vehicle
In the simplest of terms, the Hyper-Sub is the world’s first vessel that can operate as a long range, high horsepower utility speedboat and then, on demand, operate (independently) in a superior fashion as a diesel electric submarine. It can achieve this by combining time tested minisubmarine cabin(s) and systems with a proven speedboat hull and systems wherein the vessels surface hull is flooded in order to dive.
Secret Luxury Submarines Billionaires Have
Luxury submarines fit for billionaires and the world's richest people. With some costing over 100 million dollars, these are the most expensive submarines ever built.
