Superstar: Self-Sustaining City of the Future ?  

I've posted a few conceptual green buildings that are stretching the boundaries of the possible lately, but this new one from Inhabitat probably belongs more in the realm of green building fantasy than reality - The Superstar: Self-Sustaining City of the Future.

The city of tomorrow takes to the skies in an incredible new concept from Beijing-based MAD Architects. Although its spires may look menacing, the aptly named Superstar is a completely self-sustaining city that is capable of producing all of its own power and food while recycling all of its waste. Conceived as a future-forward update to the contemporary Chinatown, the Superstar will travel the globe, supplying its host cities with energy, commerce, and cultural activities. ...

As a completely self-sustaining city, the Superstar will be capable of housing 15,000 people. It will grow its own food, recycle all of its waste, and produce its own power, even feeding some energy back into its host city’s grid.

The Superstar will also be capable of traveling around the globe, sharing Chinese culture with the cities in which it docks. Inside, one can experience fine Chinese cuisine, purchase quality Chinese goods, and participate in cultural events and celebrations. It will also offer health resorts, sports facilities, drinking-water lakes, and even a digital cemetery to remember those who have passed. According to MAD’s website, the first destination of the super star will be on the outskirts of Rome, where it will provide “an unexpected, ever-changing future imbedded in the Eternal Past”.
