Cosmo Power President Shoji Tanaka speaks as he stands between the company's personal flotation devices named "Noah," that could survive both an earthquake and the tsunami that might follow, at the company's factory 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.
