"The Line" is touted as a one-building city in the desert, stretching over 106 miles (about 170 kilometres) and housing nine million people. Designers say The Line will be powered entirely by renewable energy. The futuristic city will be run with the help of artificial intelligence and will feature an enormous artificial moon. It won’t have any roads, only flying taxis and high-speed railways that connect the various parts of the city, according to a press release.
