Watch:
The planned city in Paredes, Portugal, aims to be an environmentally sustainable city. Although it has similarities with other eco-cities, this one will have a brain, just like a living organism: a central computer that regulates everything from its water use to energy consumption.
Infrastructure and intelligent applications of the city are compared to the basic functions of a living organism: the brain uses information from sensors in every building (the nervous system) to control temperature, humidity and energy use; the kidneys collect and reuse water; cameras in public spaces (eyes and ears) are used in numerous applications such as finding parking space or lost children in shopping malls; while the stomach receives all waste and cleans materials of organic contamination before separating them for recycling. The city is planned to be fully built by 2015.
