In the summer of 1961 the upper stage of the rocket carrying the Transit 4A satellite blew up about two hours after launch. It was the first known human-made object to unintentionally explode in space, and it created hundreds of fragments of useless space junk.

On the night of February 27th, 2010, a magnitude of 8.8 earthquake hit Constitución, Chile and it was the second biggest that the world had seen in half a century. The quake and the tsunami it produced completely crushed the town. By the time it was over, more than 500 people were dead, and about 80% of the Constitución's buildings were ruined.

But the structures that Elemental delivered were a radical and controversial approach toward housing. They gave people half a house.
