Chinese Inventor Builds Homemade Submarine

Amateur inventor Tao Xiangli proves that with hard work and determination you can accomplish anything, even build a submarine.

Using old oil barrels and second-hand tools, Chinese inventor Tao Xiangli, built a functional electric submarine. Xiangli, age 34, spent two years tinkering on his dream machine and ended up paying 30,000 yuan (that's about $4,000) for his invention. According to China Daily, the submarine is fully functional and comes equipped with a periscope, depth control tanks, electric motors, manometer, and two propellers. After acquiring government permission, he decided to take his homemade sub for a test dive in a lake on the outskirts of Beijing on September 3, 2009.
