This last year has seen a number of natural disasters and conflicts. For those whose lives are in jeopardy, there is a new invention which could prove significant.
Concrete Canvas Shelters, designed by British engineers Peter Brewin and Will Crawford, are a type of inflatable fabric shelter, that when sprayed with water, turn to hard concrete within 24 hours. The original design has won a number of awards including the Saatchi & Saatchi Award for World Changing Ideas.
The shelters provide safer living space for refugees, as unlike tents they are lockable, fireproof, cool in the sun and will last for decades.
The shelters can then also be covered with sand, soil or snow to provide extra protection or warmth.
