A small Japanese company has developed a modern, miniature version of Noah’s Ark in case Japan is hit by another massive earthquake and tsunami: a floating capsule that looks like a huge tennis ball.

Cosmo Power President Shoji Tanaka speaks as he stands next to the company's personal flotation device named "Noah", which could survive both an earthquake and the tsunami that might follow, at a port in Hiratsuka, south of Tokyo October 3, 2011. It's not quite a yellow submarine, since it's destined for travel on top of the water, not under it. But the round yellow pod, christened "Noah" for the maker of the ark, could mean the difference between life and death in the case of another killer earthquake and tsunami like the one that hit Japan seven months ago, said its inventor, Tanaka.
