PinkCloud.DK has come up with a design that could transform 400 oil refineries around the world into giant energy positive communities. When the planet hits peak oil and there is no longer any use for the 49,000 silos that are used to store reserves, these spherical structures could make the perfect solar-powered homes. Their shape optimizes sunlight capture and they are also airtight, waterproof, and structurally bulletproof. An individual silo can be turned into a single family day-lit home, or whole refineries can be converted into interconnected communities that share resources.
