Astana, the capital of Kazakhstan, which for a while was thought to be fictional, plans to build a huge transparent tent over its citizens that will be big enough to contain 10 football fields but will actually be a climate-controlled city complex called Khan Shatyry. The tent material will be of a special kind, designed to trap the sunlight during the bitter Kazakh winters, according to press reports, and we already envision a whole city asphyxiated.
