Yang Zongfu spent 2 years and 1.5 million yuan ($23,400) in creating his safe bubble.

With a diameter of 4 meters and a weight of 6 tons, the ark has a safe seat, observation and ventilation systems with basic living facilities designed to avoid disasters, radiation and high temperatures.

A physics professor with Nanchang University Liao Qinghua said Yang's "Noah's Ark" is basically feasible and can be made with physics theory.

A man from Shanxi province is said to have booked 15 "Noah's Ark" invented by Yang, according to the Modern Express.

Yang has more than 300 national patents for inventions and was received by Chinese Premier Wen Jiabao in 2008 for his idea on shoveling snow equipment.
