Transcript of Renaissance Submarine

The first form of the submarine was developed by Leonardo da Vinci however he kept it a secret because he didn't want to make war more scary. The Submarine In 1578 William Bourne, a British mathematician and writer on naval subjects, made another submarine plan but it was never built. It used tanks that made it submerge when they were filled an it was emptied when they wanted to make it rise to the surface. Cornelis Drebbel was born in the Netherlands in 1572 and
died being extremely poor in 1633. He also invented the
"Perpetual mobile", Thermostat, Thermoscope, and Optics.
Cornelis also did work in Dyeing and in Chemical Technology.
He was a very smart man. In 1620 Cornelis Drebbel invented a submarine that was a rowboat covered with leather that had oars. The oars came out of water tight seals. Also 12 people could fit. It could stay under water for 2-3 hours however it could only go 15 feet under sea. Cornelis' submarine was alot like William's because the submarine's outer hull had a wooden structure covered with leather, and oars coming through tight fitted leather flaps which let it propell above water and below. Leonardo da Vinci was the first to think of the submarine however he never built it because he didn't want to make war more scary. As you can see these great people had a big impact on the modern day submarine we use today. Without the renaissance who knows if the submarine would have ever been built.
