Pinkcloud.dk says that there are 49,000 oil silos around the world. They are made to contain compressed liquefied petroleum gas and stand up to rough conditions. The structurally stable spheres offer numerous advantages for solar power generation and rainwater collection. Best of all, they're already built- so no more energy needs to go into creating new buildings while the silos lay abandoned.
