Build a city that runs entirely on solar energy and other renewable energy sources, with a sustainable, zero-carbon, zero-waste ecology

Model it after the city that is currently being constructed on the outskirts of Abu Dhabi in the U.A.E. – Ecological Model City Masdar. Masdar will have many innovative green technologies which include electric vehicles, guided in part by magnets embedded in the road, will act as driverless taxicabs serving 83 stations situated throughout the roughly 2.5-square-mile city. Meanwhile, two electric rail systems will connect Masdar to the outside, carbon-polluting world. Source: http://www.sciencedaily.com/releases/2009/06/090629081849.htm
