A spherical pod, named "Noah's Ark", designed by Chinese inventor Liu Qiyuan floats on a river during a test in Xianghe, Hebei province, December 12, 2012. Liu, who has spent 1.8 million yuan ($288,000) on building six "Noah's Ark"s in 8 months with the help of his former furniture factory's workers, is working on his seventh pod. The 17 cubic-metre volume vessels were built to serve as lifeboats in the event of earthquakes, tsunamis and floods.
