I recently read about proposed Eco-City in Tianjin, China that is set to be completed in 2020. It reminds me a lot of Sim City 2000.
Here is a bit from the article, which also has more 3D mockup pictures.
"The 30 square kilometer Eco-City in Tianjin, China is set to be completed in 2020. The Eco-project was designed by Surbana Urban Planning Group which will showcase the hottest new energy-saving technologies like wind and solar power, rainwater recycling and waste-water treatment/desalination of sea water. International news sites reported that the Eco-City is expected to house 350,000 residents in Tianjin. The city was said to be divided in seven sectors which differ in terms of landscaping and programmatic offerings. A Lifescape, an Eco-Valley, a Solarscape, an Urbanscape, a Windscape, an Earthscape and Eco-Corridors."
Hopefully it become a reality and works out better then Ordos, China, which was expected to house millions and is still currently a ghost town.
