The Marine Materials Laboratory is the most important laboratory for 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 on the edge of a pool of more than ten square meters.

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

They nodded to each other, not 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, and the waves crash on the edge of the pool, splashing the water.

Zhou Yu knew some about the Blue Ocean Project, and when he saw this pool experiment, he knew that the pool represented 70% of the surface area of the ocean, and this palm-sized city model represented the most important part of the Blue Ocean Project.

The most important goal of the Blue Ocean Project is to develop the ocean, and the development of the ocean cannot always be carried out by boat every day.

If you really want to develop the ocean, you have to stay in the developed sea area for a long time.

Personnel will not have any problems if they stay on the ship for a short time, but if they live in a small cabin for several years in a row, no matter how normal they are, they will have psychological problems.

Only a floating city can solve most of the problems encountered in marine development.

After reading the experimental data, Feng Yunde breathed a long sigh of relief and said: "The base of the floating city has been able to resist super typhoons, as long as the houses above the water city are specially built and reinforced, and no houses with more than three floors are built, there is enough self-protection ability in the event of a super typhoon."

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

Feng Yunde nodded and said: "Mr. Zhou, we have verified the model and designed a water city that can withstand a super typhoon through quantum computer simulation.

Even in the event of a super typhoon, the floating city can provide citizens with a safe enough shelter to avoid the harassment brought by the super typhoon. ”

"The design of the floating city has taken shape, and how will he fix it on the surface of the water, and will it drift with the ocean currents?" Zhou Yu asked with concern.

"We designed a city on the water, which can be pushed in a certain direction by a propeller, but it has a very strong anchoring system.

Even if it encounters a super typhoon, it can be tightly fixed on the sea surface instead of drifting with the wind. Feng Yunde said proudly.

He then introduced to Zhou Yu the reasons why the water city can achieve this effect.

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

Due to the difference in size and load of water cities, super buoyancy materials will go deep into 10~50 meters underwater.

Archimedes discovered at a very early age that the buoyancy provided by water was equal to the gravitational force of an object discharging water.

When an object is completely immersed in water, the material takes on three states in the water depending on the density of the material.

The density of the material is less than that of water, and it is in a floating state in the water. The density of the material is equal to the density of water, and it is suspended in water. The density of the material is greater than that of water, and it is in a sinking state in the water.

The density of super-buoyant materials is much smaller than that of water, and the volume of water it can dislodge is also considerable.

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

After listening to Feng Yunde's narration, Zhou Yu asked suspiciously: "The properties of this super buoyancy material are very good, but only this material is not good for building a water city."

It's like placing a block of wood with a high center of gravity in the water, and the slightest ripple in the water will cause the block to capsize.

If the mass of the block is suddenly reduced, it will also float rapidly, causing the entire block to capsize.

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

Feng Yunde said confidently: "Mr. Zhou, if there is only a super buoyancy material, which constitutes a water city, then he must be the most garbage water city."

In addition to our super buoyancy materials that provide sufficient buoyancy, we also have very advanced anchoring systems.

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 anchor, using a large mass object to form an anchor to fix the city on the water.

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

Especially under the influence of submarine currents and undercurrents, anchors in a suspended state will also drift with the currents, directly affecting the water city, which is not the best fixing scheme.

We found a hydrogelling material that, when fused with water, can change the properties of water, turning it into a jelly-like colloid.

At the same time, it does not change the density of the water, so that the hydrogel remains in its own place.

In this way, as long as a mesh rope is used, a large area of hydrogel can be made at a certain water depth.

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

This hydrogel does not affect the buoyancy of the floating city relative to the mass anchor, 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 tightly hold the water city and let it stabilize in the super wind and waves. ”

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

"How safe is this hydrogel material, and does it have an impact on the marine ecosystem?" Zhou Yu asked.

"Mr. Zhou, the hydrogel material is similar to the material jelly, marine organisms cannot enter it, and it does not have any toxic side effects, even if it is eaten by creatures, there is no problem, 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.

After degrading to a certain extent, the seawater becomes viscous and slowly returns to its normal state.

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

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 water again.

It is a very safe and reliable anchoring system that does not affect the marine ecology and can also hold the water city firmly in its relative position. ”

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

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