Cosmo Power, a Japanese engineering company, has developed the “Noah” a four person mini-ark to help residents along Japan’s coast survive a future tsunami. The “Noah” is a four foot diameter bright yellow sphere made of fiber-reinforced plastic. It is self righting and can survive a 33 foot drop. It also can be used as a toy house for children. The pod retails for about $3,800 and more than 1,000 have been ordered.
