The "sea city" is about to be built. Do you want to emigrate to the sea?

In 2500 AD, due to the melting of polar glaciers, the earth became Wang Yang, people lived on water, and the soil became a rare thing ... This is the picture described for us by the sci-fi movie Future Water World. In fact, our planet is indeed facing the threat of rising sea level.

Compared with the beginning of the 20th century, the sea level has risen by nearly 20 cm. It is estimated that this number will reach 65 cm in 2 100 ... after one hundred years, where will human beings live safely, and will they live on the seabed like Atlanteans? The good news is that engineers are building a new home at sea-a city floating on the sea!

Everyone has heard of the "greenhouse effect". For many people, the greenhouse effect may not be so obvious, but those who live on islands far from the mainland don't think so, because the greenhouse effect means losing their homes.

For example, Tuvalu, a Pacific island country that is about to sink, is calculated according to the speed of sea level rise in previous years. It is estimated that in 50 years, at least 60% of Tuvalu's land will be completely submerged.

There is also Nauru in Oceania, an island country with an average elevation of only 45 cm. They will move the whole population to Australia in the future. It seems that it is really urgent for a country surrounded by the sea to find its own way out.

But can moving to a higher place guarantee long-term security? In order to race against the rising sea level, engineers are considering building an ocean home for mankind. Sounds like science fiction, right? Let's see what blueprints the engineers have planned.

The offshore city designed by a company in Florida, USA, is called Freedom. It looks like a huge cruise ship! Full of steel and industrial beauty, the top floor of this big guy is almost exactly the same as an aircraft carrier-the purpose is to let the plane take off and land. Freedom is 1372 m long, 229 m wide and 107 m high, almost four times as long as the world's largest cruise ship "Queen Mary 2"! If you want to walk from the bow to the stern, you must work hard.

Free travel has all kinds of facilities, with a total of 25 floors and about 18000 rooms. In addition to regular houses, libraries, schools, hospitals, restaurants and factories, you can also find all the facilities of the land community here. Freedom is expected to accommodate 50,000 long-term residents and 20,000 crew members, as well as 30,000 visitors and 65,438+0,000 people!

It is powered by solar energy and wave energy, and can circle the earth once in two years, which is almost a modern version of Noah's Ark. Buy a house and travel around the world in the future! High cost performance!

However, ships are used for sailing after all. In order to truly realize the maritime city, engineers try to solve the problem from another angle, and "Utopia" is one of the embryonic forms. Utopia is like an electric vacuum cleaner standing on the sea with four feet, which can keep balance in the rough sea. The azimuth thruster on each foot also makes it easier to control.

And its own length and width is not less than 100 m, its height is 1 1 deck, and the observation deck at the highest point is 65 m away from the sea level. Coupled with the perfect life and entertainment service area, it is no wonder that designers confidently say that "Utopia" is a complete "micro-country"

In addition to the "Utopia" at sea, scientists also built a floating city in Tahiti. This water kingdom with an investment of more than 60 million US dollars will be completed in 2020. Each platform in the floating city is about the size of a baseball infield, and these platforms will be connected through special channels.

Floating cities are distributed in a network, like a huge spider web on the sea. There are not only villas, apartments, research institutions, underwater restaurants and other entertainment facilities, but also aquaculture farms, medical and scientific research facilities.

What makes the builders proud is that all the materials used to build this city are environmentally friendly and recyclable. Marine ecosystem can produce oxygen and electricity, and recover carbon dioxide and waste at the same time. The purification and softening of water is completed by the ecosystem, which basically realizes the ecological chain of resource recycling.

"Water draft" and "floating city" can make residents get food in the ocean and be self-sufficient. They can also use seawater to generate electricity. Seawater can be desalinated into edible water, and there is a green ecological park that can filter wastewater.

Cities built on the sea also have Dubai people's "floating seahorses".

This floating villa looks like a small box from a distance. The seemingly ordinary appearance hides low-key luxury and countless black technologies. Each floating villa has three floors, one under water and two above water. The most interesting thing is the underwater floor, including a master bedroom and a bathroom.

The first floor above sea level is an open living room, dining room and kitchen. There is also a leisure area outside the living room where people can enjoy sunbathing. The top floor is a mini-bar and jacuzzi. Close the retractable curtains by remote control, and the sunshine deck instantly becomes people's living space. This "floating seahorse" covers an area of about 300 square meters and costs about180,000 RMB.

In addition, the Netherlands is also developing double-decker houses floating on the sea. The first floor of the house is designed underwater, which can lower the center of gravity and be more stable at sea. The designer's idea is that these offshore houses can form communities in the vast sea at any time, and then develop the city; Of course, you can also split from Haicheng and travel around the world at any time.

The increasing population and rising sea level test the wisdom and creativity of human beings to the greatest extent, and also promote the study of settlement at sea.

Although it is difficult for human beings to give up their feelings for the land, it is also an advantage of human beings to take things as they are, adapt to local conditions and sing on any hill. For human beings in the future, life is to get up in the morning. The sunshine on the sea makes the room full of gold, and huge fish migrating along the ocean current swim outside the transparent kitchen wall. Open the door at night, there will be sea breeze and stars ... will they still miss their down-to-earth life?
