One-Man Submarine Built By One Man

Tao Xiangli may only have an elementary school education, but he built his own 20-foot, 1.8-ton submarine from some metal barrels and miscellaneous parts he could scrap together. Fitting only himself, the interior also houses pressure meters, oxygen tanks, headlights, video cameras and a TV monitor. The entire submarine cost Xiangli $4,366, or about one year's pay. Its maximum cruising depth is 10 meters. [Ananova via Gearfuse]
