Anonymous Coward writes: "Chinese Karaoke technician Tao Xiangli has built a working submarine mainly from oil barrels and scrap. The 34 year old constructed the one man 6.5m long craft in just 2 years and claims it can dive to a depth of 10m. The craft has its own oxygen supply, underwater cameras and pressure monitors. So far it has cost him 30,000 yuan ($4,400) but he hopes that the invention will bring him fame and financial backing.
