Ananova reports on a retired Chinese man whom the government has allowed to build amateur submarines:
Li Yuming, 68, who has only an elementary school education, has built seven submarines since 2003, reports IC Media. Li, from Hanyang, Hubei Province, has now been granted a license to make recreational submarines, yachts, ferries and fishing boats.
The retired shoe maker spends all his free time inventing things: “I like challenges, especially those which seem impossible,” he said. Li’s first four submarines were not fully seaworthy and the fifth one he built was the first to notch up a successful voyage.
His latest creation is an unmanned submarine which is just one metre long but which can dive to a depth of 30 metres. Experts say Li?s spirit is commendable, but his submarines are not entirely practical. “Most of his constructions are based on imagination and the final products are quite rough,” one told IC Media.
