This is a concept of a foldable house created by Spanish designer Martin Azua. When it’s folded, the synthetic cupola fits a man’s pocket. But once you need a shelter, you may instantly inflate the “House” with body heat or solar rays. The material is reversible and you may choose whether to reflect inner or outer heat waves and so keep the shelter either warm or cool inside.
Just think if every homeless person in the world had one of these….just a thought.
