Tao Xiangli, a Chinese inventor, is reported to have built a functional submarine:
Amateur inventor Tao, 34, made a fully functional submarine, which has a periscope, depth control tanks, electric motors, manometer, and two propellers, from old oil barrels and tools which he bought at a second-hand market. He took 2 years to invent and test the submarine which costs 30,000 yuan (US$4,385).
This comes a month after a Chinese farmer was reported to have built a helicopter from spare parts.
