The best designs are those that can improve lives.  Ikea is designing a flat pack, easy to assemble housing unit intended to replace tents in refugee camps.  Unlike the typical canvas tents that last only about 6 month, these will last up to three years and will provide insulation and electric lights thanks to solar panels on the roof.  The icing on the cake: they are expected to cost $2,000 less than tents over a 3 year period.
