Thanks to U.S.-based Survival Capsule LLC, they have come up with what is deemed to be one of the most advanced concepts of the two-man design, where it is being reworked on to ensure that eventually, it can hold up to at least 10 people inside. In a nutshell (pardon the pun), the ‘tsunami survival capsule will be a place where people run inside for safety whenever there is an impending tsunami. I would suppose that the insides of the tsunami survival capsule would have seats that require “passengers” to be strapped in, as you can never quite tell just which direction you would be bouncing in when the tsunami hits.
These ‘tsunami survival capsules ought to be placed on top of public buildings as well as houses, since that would increase the chances of survival as no matter how tough it has been created to be, surely it cannot withstand the drop of a 10-ton piece of concrete that had just broken off a building. Theoretically speaking, the tsunami survival capsule will protect its “passengers against fast floating debris.
