450 words of underwater city composition

In the future, there will be a second home for mankind-an underwater city that makes full use of marine resources.

In order to resist the great pressure of seawater, this underwater world was built in a huge coral colony. Through a long corridor, you can enter this huge coral community. Many huge round water polo balls have been built here. This is a house where human beings live. Humans immigrated here from land.

The climate in the underwater world is very similar to that on land. You must ask, how can you live without sunshine and water on the seabed? You don't have to worry, there are two huge machines in the deepest part of the underwater world, one is a sunlight processor and the other is a well-known seawater desalination device. This solar processor is directly connected to the ground, absorbs the sunlight from the ground, and then transmits it to the solar cell at the bottom of each water polo through the pipeline, and then converts it into electric energy and transmits it to the energy lamp at the top of the water polo. The seawater desalinator directly absorbs seawater, desalinates seawater, and then sends it to the water polo.

Underwater world is an environmentally friendly world. In order to protect the environment, people ride a well-trained dolphin. Because the living space has been broadened, there are no high-rise buildings here, only rows of energy-saving bungalows.

Although the construction of the underwater world will be very difficult, I firmly believe that as long as we exert our intelligence and dexterous hands, staying in the underwater city will never be a dream in the near future.

Two future undersea cities

One day in 20XX, I became an engineer in an underwater city in a blink of an eye.

I want to build an underwater city full of infinite fun. Between this thought, a picture of the construction of an underwater city was formed in my mind.

The picture is like this-first of all, I want to install a radar underwater detector, so that in a certain land area, I can avoid the attacks of big fish and monsters, because the detector will call the police first, and then automatically set a protective cover to prevent big fish from getting in. With the safety system, we should now consider how people breathe air and how to build houses. I will build a house with a special kind of brick. The more magical the bricks used in this house, the better, because the most important thing is to create fresh air and make people breathe "tasteful". Secondly, a brick house can be any color you want, because all you have to do is draw a place outside the house by hand, and then say a color you want this place to change. When you find that the new year is coming, you can point to the house "intercom" and say "red". The house will turn red and make you feel really happy. If you want to see the scenery outside in the house, you can say "transparent" into the intercom, and the house will be very obedient and transparent, so you can enjoy the scenery outside in the room. ...

If you feel that water has entered the room, you can buy a "backwater" and install it at the door. As long as you press a button, the water will be automatically discharged and will never enter the room again, so live boldly! Everything is wrong. As an engineer, I will definitely come up with a good solution!

I am looking forward to the future underwater city!

Three future undersea cities

In 2054, due to natural disasters such as tsunami and earthquake, the last part of the land was flooded. So, where will the surviving humans live after losing their homes? Don't worry. Scientists have thought about this problem for a long time, and have designed our future marine home.

Underwater cities are made up of huge transparent bubble houses, which are firmly fixed on the bottom of the sea and will not move with the ocean currents. There is a huge pipeline connection between each bubble house, which becomes the traffic artery of the underwater city like a road. Everything in people's daily life in the city hasn't changed much. Crops are soilless, people breathe oxygen released by plants, and plants absorb carbon dioxide. Solar energy collected from the sea surface is the main energy source, and the "garbage converter" can also convert all kinds of garbage into the energy people need. The "seawater desalination device" provides us with the fresh water we need every day. Through the "ecological cycle simulation technology", people can also feel the seasonal changes in spring, summer, autumn and winter. The beautiful underwater scenery outside the bubble house is your back garden. If one day, you want to enjoy the real sunshine, then take a "multi-functional submarine" and go to the sea castle for a holiday!

On the blue sea, there is a huge luxury hotel floating, which consists of 220 rooms, bars, restaurants, shops and theaters, all of which are located at sea and have a large area. If you want to go there, guests can take the train located in the tunnel from land to this sea hotel.

By the way, people's means of travel at that time were private underwater submarines. If you want to put a good place, go to the underwater parking lot! There is no charge for parking there, and the safety measures try to reassure you. It is parked in the underwater parking lot and will not waste the precious space of the underwater city. Drivers can get here by subway or on foot.

Ocean world, this is a happy paradise for our future life!

Four future undersea cities

In the future, due to the shortage of living space for human beings, people will no longer live on land, but in beautiful oceans. Now let's visit the underwater city!

Take this little pill first. It has the function of letting us breathe underwater and protecting our eyes, and the effect can last for one year. All right! Let's just jump into the water! As soon as you jump into the water, the first thing you see is a gate. There is a robot beside the gate. It enthusiastically said to us: "Welcome to the underwater city of' Blue Ocean'. Please choose between' going home' and' visiting'. " Let's go home first! "Whoosh" moment, I have returned home, my parents have been waiting at home, with their consent, I took my' marine pet-crystal fish' to play.

Whoosh, the flying fish bus came, and I got on the bus with my pet fish. The car is very big, it can seat thousands of people, and its speed can be compared with that of the train, but there has never been a traffic accident. There are many recreational facilities in it, but when I got to the station, I got off with my pet fish.

When the Amizia Garden arrived, my fingerprints were gently placed on the unmanned ticket counter at the door. The door opened with a bang and I went in. Very beautiful, with coral and seaweed ... colorful, it's just a fairyland in the water. At this time, a nine-color fish swam over. "It's half past nine, at the bottom of the sea. What can I do for you? " "No, thanks." That fish is a guide to future technology. It is beautiful and cheap. "Feng Zaimin, it's lunch time, and your mother is waiting for you at home." The underwater broadcast made a sound, so I had to reluctantly leave this unforgettable underwater wonderland.

This is the future underwater city.

5 undersea cities

In the future, there will be a second home for mankind in the world-an undersea city that makes full use of undersea resources.

In order to resist the great pressure of seawater, this underwater city is built in a huge coral. Through a long corridor, you can enter the underwater city. Many huge round water polo balls have been built here. This is a house where human beings live, and there are many human beings who immigrated from land.

The climate in the underwater world is very similar to that on land. You must ask, how can you live without sunshine and fresh water at the bottom of the sea? Don't worry, there are two huge machines in the deepest part of the underwater world, one is the sunlight processor and the other is the seawater desalination device. This sunlight processor is directly connected to the ground, absorbs sunlight from the ground and then transmits it to various houses through pipes. The seawater purifier directly absorbs seawater, then carries out fresh water treatment, and finally sends it to the major water balloons.

Underwater world is an environmentally friendly world. In order to protect the environment, cars, motorcycles and other vehicles that pollute the environment have been eliminated and replaced by well-trained dolphins. Dolphins are very similar to humans, so they are very suitable for transportation.

I believe that as long as we use hard-working hands, we can make the underwater city construction successful!
