A Chinese labourer with only a basic school education has made a submarine at home. Tao Xiangli made the 1.6 tonnes submarine mostly from metal barrels and improvised parts by hand.
Tao said the basic submarine cost him £2,200, the equivalent of a year’s pay. Tao is now in the final phase of debugging the submarine and hopes it will make its maiden voyage within the next week in Beijing. He says it can dive to a maximum depth of 10 meters, and should be quite safe.
