It just looks like a proof of concept. They tested it in very controlled conditions. Did not see how it withstands being knocked over, dropped, covered in dust from storms. Their market is Africa. How many of the towns have road access? Will the product be damaged in transport on very rough roads? Can they be stacked in transport, and how many high (or will they be crushed)? Will adhesives fail after n temperature cycles in the blazing sun + nighttime cold? Can it be repaired by people living there? Almost every part looks to be made from scratch. The only thing off the shelf is the pink insulation foam. Can any of this be sourced in the target markets?
