A new city in the future

  Someday in the future, you may live 200 meters below the dark sea surface, or live in a super high 290-story skyscraper. Some large cities in the world are already facing the problem of population overload, and 100 years later, the population of the earth may exceed 11.3 billion. Therefore, urban planners are racking their brains, giving full play to their imagination, and using various available technical means to ensure that human living spaces are safe, comfortable and livable in the future.
  Architects and engineers from the University of Westminster in London, UK, showed us the top ten most popular designs for future urban planning, such as floating cities, roof agriculture, and underground buildings. Some construction methods are now in use, but a number of optimization projects are still needed to cope with the growing population and deteriorating climate issues.
  City floating
  sea-level rise for the future of low-lying coastal areas will be a major threat, therefore, urban planners must pay attention to the relationship between the city and the water surface. Interestingly, although these areas are threatened by water, safe and dry residential areas can be built.
  Scientists from the Institute of Ocean Homes in the United States have developed square and pentagonal concrete platforms with a bottom side of 50 meters. The platforms are equipped with hollow areas so that the building platform can float in the water. The two shapes of building infrastructure can be more These forms are combined together.
  The city of New Orleans in the United States often needs to deal with flood disasters and has experience in flooding. Marine technology experts from the University of New Orleans tested floating construction platforms in a large tank, and simulated artificial water wave tests of different heights and widths. These concrete platforms must withstand the erosion of seawater in the future, resist the erosion of waves, and have sufficient Strength of.
  Port gateway to space,
  the future of the city will be provided with space port, where people can take the aircraft space travel. Before we actually settle in the new world, we may already be able to perform short-term space missions.
  The first commercial space port on Earth, the US Airport, has been built in the desert of New Mexico, USA. According to the plan, Spacecraft II will be the world’s first passenger traveling spacecraft. This aircraft is manufactured by Virgin Galactic, can carry 6 tourists to an altitude of 110 kilometers to experience a 5-minute weightless state, and can overlook our earth from space.
  Seven other space ports in the United States are also planned to be built to allow manned space travel. According to experts, such space travel will become a reality within a few decades.
  Print out your house
  future house may be printed out from the large-scale machinery. Chinese technology companies have begun to use related technologies to print architectural structures. The printer used for the job is 6.5 meters high, 10 meters wide, and 40 meters long. According to their construction rate, it only takes 24 hours to print 10 fully functional villas. The printing materials used are all recycled materials, such as rubber and glass replaced from old buildings, which is more environmentally friendly. The quick-drying cement can be used as a raw material to print out the basic unit structure of a house, which can be easily combined and stacked to build a 5-story housing building. The printed wall is hollow with zigzag grooves for easy assembly and stacking. The hollow wall makes the building have good heat insulation. The room is warm in winter and cool in summer. There is a well-designed cross-beam network inside the wall to support the building and ensure its strength and safety.
  Houses printed by 3D technology have extremely high commercial value, because the recyclable materials used in this construction technology can reduce the cost of building materials by 30% to 60%, while the project cycle is short and the required labor costs are low.
  Urban dimension to extend from the bridge
  to the future, the city’s large population could grow to 40 million. In order to solve the traffic congestion caused by overpopulation, in the future, many roads and tracks will be extended from the ground to the air with the help of very large bridges. Now, in order to relieve the traffic pressure, Dubai has proposed the design idea of ​​building super-long bridge roads, which can span the entire city.
  Underwater city
  underwater city exist only in science fiction right? That’s not necessarily true. At present, hotels and laboratories have appeared in some countries and regions in the world, and they are all located at a depth of about 20 meters underwater.
  But if you ask Japan’s Shimizu Company, they will tell you that we can also enjoy deeper submarine space. Shimizu has developed underwater spiral structure construction technology. According to the plan, an underwater city can accommodate 5,000 people and can effectively avoid extreme weather such as typhoons. To build such a submarine city, it is necessary to construct a complex oxygen supply system and a safe retreat system, as well as appropriate methods to effectively utilize the unlimited energy in the deep sea. Scientists plan to use methane as an energy source to extract this substance from carbon dioxide emitted by marine microorganisms. There are temperature differences in different depths and regions in the ocean. Through the conversion of ocean thermal energy, this energy can be used to generate electricity. In addition, the seawater desalination system can effectively use marine water resources to meet the living needs of seabed residents.
  This far-sighted Japanese company hopes that the underwater city will lead to the seabed through a 15-kilometer-long spiral channel, where there will be entertainment areas and scientific research institutes.
  Depth cloud skyscraper
  matter of humans right now, the construction of high-rise buildings, such as the end of a two kilometers towering buildings, not difficult to resolve technical problems, but the amount of money spent. Even if the ground is porous and the ground is loose, engineers can use some methods to build tall buildings. The 828-meter-high Alifa Tower skyscraper in Dubai was built on the sand. 192 pillars were drilled into the ground 50 meters deep, firmly supporting the concrete foundation, making the tall building stable and solid.
  The next super-tall building that will exceed this height is the King’s Tower in Saudi Arabia. The project will be completed in 2019. The tower is designed to reach a height of 1 kilometer. The King’s Tower will not always be in the forefront of the tallest buildings, because people will continue to make breakthroughs in the height of the building. Experts predict that in the next 40 years, there will be buildings as high as 1.6 kilometers in the world. If this trend of chasing high buildings continues, there will be super-tall skyscrapers with a height of 3 kilometers in 2115.
  The city’s rooftops agro-ecosystems
  in many cities there have been small-scale vegetable cultivation roof. Hydroponic planting technology is a productive planting system that combines plant cultivation and water tank fish culture to promote each other. This technology makes the roof farming model more effective and cleaner.
  During the breeding process, the fish will emit a lot of organic matter and accumulate in the water tank or fish pond. The bacteria in the water can decompose these wastes and turn them into a “nutrition package” for plants. Next, the water is purified and returned to the fish pond to provide a clean environment for the fish.
  Raising large livestock on the roof, such as cattle and sheep, can provide humans with indispensable meat food, but it is difficult to achieve outdoor grazing. In the future, rooftop agriculture will meet this challenge through technological innovation and optimization of building structures.
  Underground construction
  in the future, may be like the ground, like underground, built a number of floors, however, the cost and the time cost of underground construction in approximately 10 times more than the ground floor, will face more technical challenges. The underground geology is complex. To build multi-story underground buildings, the underground concrete structure must be very strong and able to resist internal collapse. The deeper you build, the stronger the support around the building must be. The groundwater level also has an important impact on the construction of this kind of building structure. The presence of water will make it difficult for cement to solidify and harden. A good drainage system must be designed to solve this problem.
  Foldable transportable portable housing
  for those who are keen wandering life, the future of environmental protection capsule housing is very attractive. This small capsule apartment will be powered by wind and solar energy, and can be placed anywhere, allowing you to settle down anywhere in the world and fully enjoy the natural scenery.
  In a crowded city, it is not easy to settle down. If the houses can be stacked, it will be convenient for the homeless and help those struggling in the city to get a place to live.
  Global warming may lead to unprecedented floods and tornadoes, forcing people to leave their homes and move elsewhere. Living in a dangerous zone with frequent disasters like the Philippines, people can choose to live in a foldable portable house, which is convenient for people to quickly move to a safe place. In fact, some of these portable houses exist, but they are only used for entertainment at present.
  Low-carbon constant temperature building
  Engineers and architects can save resources on the basis of existing technology, make full use of natural energy, and create a low-carbon and environmentally friendly building microclimate through sophisticated design. The warm air rises upwards, and the air duct can adjust the temperature inside the building, allowing green plants to absorb the energy of the sun. These are simple techniques to control carbon emissions.
