An inflatable tent that turns into concrete when it gets wet has been developed by a pioneering British firm, according to the innovation company PSFK.
The new Concrete Canvas Shelter, as it is called, is easily erected by two people in less than an hour and hardens into a concrete structure once it's been filled up with water and blown up, completely setting within a day, according to PSFK.
The UK-based Concrete Canvas company seems to have made the tent with the military in mind, but it will likely be useful in natural disaster situations as well.
National Geographic described the invention's implications as "far-reaching."
