Smart city

A **smart city** is built with underlying technological systems that collect data in real-time which is analyzed and used to manage services and operations. Data collected from citizens and devices is processed and analyzed to monitor and manage traffic and transportation systems, water and energy utilities, amenities, and so on, to improve the quality of life of its citizens.

Information and communication technology (ICT) and devices connected to the Internet of Things (IoT) network to optimize the efficiency of city operations and services. Smart city applications are real-time and interactive, which allows challenges to be overcome efficiently. Such cities attract citizens from far and wide, and as more and more areas become urbanized, this could lead to megalopoli and eventually an ecumenopolis. Care has to be taken to preserve green areas, ensuring it is a green city.

### Technologies

* Smart grids with renewable energy sources such as solar power and wind power. Energy Data Management Systems (EDMS) can help to save cities energy by recording data and using it to increase efficiency.
* Smartphones and similar mobile devices allow citizens to connect to the smart city services.
* Smart homes
* Smart mobility and intelligent transportation systems
* Smart cards possess unique encrypted identifiers that allow owners to log into e-services. This aggregates data about citizens and their preferences to improve the provision of services and to determine common interests of groups.
* Embedded smart chips inserted into people under their skins can be used in the same way as smart cards.

### Future

* Floating cars are now extremely common to see on the roads. They float silently on cushions of magnetism created by a room-temperature superconducting pavement. They rarely need refuels since there’s almost no friction to slow them down as they travel.
* The external appearances of buildings can morph and change shape because of their claytronic surfaces.
* Advertisements in the form of 3d holograms are extremely commonplace.
* Electricity is passed wirelessly from building to building.
* Cameras and sensors are everywhere and they can track the footsteps, body movements, and facial expressions of every person and instantly identify those people. Even the internal biological states of humans can be monitored such as their neural activity and pulse, which can give clues about their immediate intentions.
* Android police can be summoned instantly because robotic officers now appear to grow out of the ground. This is made possible through the use of claytronics and nanobots embedded into buildings, roads, and sidewalks.
* Worker robots now outnumber humans even in downtown areas that would have been typically crowded with cars and people in earlier times. This is partly because people of today spend the majority of their time connected to virtual environments, which are many orders of magnitude more interesting than real life.
* Building surfaces, windows, and roofs are completely resistant to dirt, bacteria, rain, and graffiti. And they can self-repair in the event of damage. The coatings for these buildings are often applied to cars and other vehicles as well.
* Roads and pavements are made of special materials that clean themselves and absorb trash.
