Home-made submarine!

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, reports Zhong'an Online.

"Metal barrels are possibly the best material for me because of their low cost," said Tao, a migrant worker in Beijing.

The 20ft submarine is cramped inside with room for only one person but it features pressure metres, monitoring cameras, a TV set, oxygen supply and headlights.

"Although the equipment is simple, it's enough for a basic submarine, and more importantly, it enables the passenger to see things clearly underwater," said Tao.

It took Tao more than a year of research and experiments, but he says the most difficult challenge he faced was not a lack of knowledge, but of funds.

"The devices for submarines are all expensive, so because I couldn't afford them I found a lot of inexpensive replacements," he said.

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.

Although he has only an elementary school education, Tao owns 17 patents, including a head massager, a washing machine and a shoe polisher.
