As we learned from Wall-E, people with half a mind for themselves probably won't be kosher with living with 1.1 million or so other inhabitants within a pyramid. That being said, there's always the brainwash approach to getting 'em in there, and if hordes of people were ever filed into the conceptual Ziggurat, Mother Earth would surely appreciate it.

The 2.3-square kilometer building would be able to house over 1 million people and be "almost totally self-sufficient energy-wise." By tapping into the planet's renewable resources, designers assert that it could practically be carbon-neutral, and given that transport within the machine would be connected by an "integrated 360-degree network," fuel-burning cars would be pointless.

As with most things in Dubai, this one seems larger than life, but if the Burj Al Arab is any indication, there's at least a minuscule chance this thing comes to fruition.
