Chapter 254 Water City
The Marine Materials Laboratory is the most important laboratory of the Blue Ocean Project.

Feng Yunde has been working with researchers in this laboratory to develop the materials used in the Blue Ocean project.

If the bionic fish gills are the cornerstone of the Blue Ocean Project, the materials developed by the Marine Materials Laboratory are the backbone of the Blue Ocean Project.

Zhou Yu found Feng Yunde beside a pool of more than ten square meters.

He is putting a palm-sized city model in the pool.

They nodded to each other without making a sound to interfere with the progress of the experiment.

The undercurrent in the pool is surging, and the water surface is constantly rippling. The waves beat against the edge of the pool, splashing water.

Zhou Yu knew something about the Blue Ocean project. When he saw the pool experiment, he knew that the pool represented the ocean that covered 70% of the land surface. This palm-sized city model represented the most important part of the Blue Ocean project, the water city.

The most important goal of the blue ocean project is to develop the ocean, which cannot be done by boat every day.

If you really want to develop the ocean, the staff must stay in the development area for a long time.

People staying on board for a short period of time will not have any problems. If they live in a small cabin for several years, even normal people will have psychological problems.

Only water cities can solve most of the problems encountered in ocean development.

After reading the experimental data, Feng Yunde breathed a sigh of relief and said: "The base of the floating city can already withstand super strong typhoons. As long as the houses on the floating city are specially constructed and reinforced, and houses with more than three floors are not built, they will not be able to withstand super typhoons. The typhoon also has enough self-protection ability."

Zhou Yu stepped forward and asked, "Is the floating city ready to be officially put into use?"

Feng Yunde nodded and said: "Mr. Zhou, we have verified the model and simulated it with a quantum computer, and the designed floating city can already withstand super typhoons.

Even in the event of a super typhoon, the floating city can provide citizens with a safe enough shelter to avoid the disturbance caused by the super typhoon. "

"The water city design has already taken shape. How is it fixed on the water? Will it float with the ocean current?" Zhou Yu asked with concern.

"The water city we designed can drive in a designated direction under the propeller, but it has a very strong anchoring system.

Even in the event of a super typhoon, it can be firmly fixed on the sea surface instead of floating with the wind. "Feng Yunde said proudly.

He then introduced to Zhou Yu the reason why the floating city can achieve this effect.

The base of the floating city is made of super buoyancy material to ensure the maximum displacement of water volume and the strong buoyancy to maintain the survival of the floating city.

Due to the difference in size and load of the water city, the super buoyancy material will go deep into the water 10-50 meters.

Archimedes discovered very early on that the buoyancy provided by water is equal to the weight of the water displaced by the object.

If an object is completely immersed in water, the material will appear in three states in water according to the density of the material.

The density of the material is less than that of water, and it floats in the water.The density of the material is equal to that of water, and it is suspended in water.The density of the material is greater than that of water, and it sinks in the water.

The density of super buoyancy material is much smaller than that of water, and the volume it can displace is relatively considerable.

The most important thing is the toughness, hardness, and wear resistance of this material are excellent, not inferior to metal alloys at all. It also has very good corrosion resistance and can exist in seawater for a long time.

After Zhou Yu listened to Feng Yunde's narration, he asked suspiciously: "This kind of super buoyancy material has very good properties, but only this kind of material is not good for building a floating city.

He is like placing a wooden block with a high center of gravity in the water, and the wooden block will overturn if there is a slight fluctuation in the water.

If the mass carried by the block suddenly decreases, it will also rise rapidly, causing the entire block to topple over.

The overturning of a wooden block will not have serious consequences, but the overturning of a floating city will cause tens of thousands or even hundreds of thousands of people to die under the sea. "

Feng Yunde said confidently: "Mr. Zhou, if there is only super buoyant material, this kind of material constitutes a floating city, then it must be the most garbage floating city.

In addition to the super buoyancy material to provide sufficient buoyancy, we also have a very advanced anchoring system.

Floating cities are sometimes located in the deep sea and cannot be anchored by piling.

The conventional anchoring scheme is very similar to a ship's anchor, which uses a large mass of objects to form an anchor to fix the floating city.

But this kind of scheme is a very poor scheme, and the large-mass anchor consumes the vital buoyancy of the floating city.Let the facilities related to the water city be poorly arranged.

Especially under the influence of ocean currents and undercurrents on the seabed, the suspended anchor will also drift with the ocean currents, directly affecting the city on the water, which is not the best fixed solution.

We have discovered a hydraulic material that, when fused with water, can change the properties of the water, turning the water into a jelly-like colloid.

At the same time, the density of the water is not changed, so that the hydrogel remains in its original position.

In this way, a large-area hydrogel can be produced at a certain water depth by using a mesh rope.

Once the large-area hydrogel is formed, it is resisted by water and cannot move in water.

Compared with the mass anchor, this hydrogel will not affect the buoyancy of the floating city, but it can fix the floating city in a relative position.

The anchoring system composed of this hydrogel is very stable. Even in the event of a super typhoon, it can hold the floating city tightly and stabilize it in the super strong wind and waves. "

Zhou Yu heard Feng Yunde's introduction, and he understood the powerful role played by this hydrogel material.

"How is the safety of this hydrogel material, and whether it has an impact on the marine ecosystem." Zhou Yu asked.

"Mr. Zhou, the hydrogel material is similar to jelly. Marine organisms cannot enter it, and it has no toxic side effects. Even if it is eaten by organisms, there will be no problem in the stomach, and it will not affect the marine ecosystem. .

A material that fuses with water to form a hydrogel, which slowly degrades in the marine environment.

When degraded to a certain extent, seawater will become viscous, and then slowly return to normal seawater state.

Its critical point is one year, and the hydrogel must be continuously replenished with the materials that make up the hydrogel every year.

If we abandon the original location of the floating city, it will only take a year for nature to decompose these hydrogels and turn them into flowing sea water again.

This is a very safe and reliable anchoring system that will not affect the marine ecological environment, and it can also firmly pull the floating city and fix it in a relative position. "

Zhou Yu gave a thumbs up and praised the performance of this material. He knew that Feng Yunde and the others must have worked hard to develop a hydrogel material that is extremely suitable for water cities.

Knowing the characteristics of the water city, Zhou Yu and Feng Yunde walked out of the laboratory, and they discussed the planning of the water city with relevant experts.
