What is it with everyday Chinese folks building extraordinary things? Last month farmer Wu Zhongyuan built a helicopter from wood and metal. This month Tao Xiangl is scooting around the waters near Beijing in a hand-built submarine.
Meanwhile, I just created charcoal while trying to make a bagel.
The rig cost Tao 30,000 yuan ($4,385) and two years to build, and includes a periscope and depth control tank. No mention of a sonar system, but knowing the Chinese farmers these days that DIY achievement has to be just a matter of time. [China Daily via Gizmo Watch via DVICE]
