The Three-Body Problem: The Most Competent Wallfacer of All Time

Chapter 186 Artificial Ecosystem

Jiang Yu remembered that Qi Guanglu was over 70 this year, but he looked younger than eight years ago.

Zhao Yun smiled and said: "People are in good spirits every happy event. Professor Qi's project team has made such great achievements, which makes Professor Qi look a lot younger."

Qi Guanglu's achievements here are obvious. When Jiang Yu came last time, although a new variety of wheat was planted here, the surrounding environment was still relatively desolate.

Now it is already a lush green scene, and sparse forests can be seen in the distance.

Qi Guanglu smiled and introduced to Jiang Yu: "Actually, there are no new breakthroughs in the Green Green Project. We have thought of the method of creating green space here before, but it has only made enough progress in technology in recent years."

He took Jiang Yu and others: "Please follow me."

This piece of green in the desert, the outermost is the grassland, and walking tens of meters inside is the main crops in the north such as wheat and corn.

As soon as he entered the crop area, Jiang Yu felt that the air humidity here seemed to have changed.

Qi Guanglu walked in front and introduced: "In fact, many people shout about soil erosion every day, but they don't know the meaning and harm of soil erosion.

"A poplar tree can store several hundred kilograms of water during the rainy season, and a poplar forest can almost absorb excess rainwater that can cause floods.

"Without flooding, we can ensure that the land resources in the forest will not be lost, and the water absorbed by the trees will be gradually released into the surrounding environment, ensuring that the surrounding environment has enough water.

"But when there are no forests, soil and water cannot be retained, and complications of soil erosion will follow.

"If you don't have trees that absorb water, you're prone to floods. If you don't have trees that release water continuously, you're prone to drought."

While listening to Qi Guanglu explaining these knowledge, Jiang Yu saw a tall white pagoda not far away.

This white tower is made of metal, and from the bottom to the top, there seems to be a circle of small holes.

Qi Guanglu was leading them to the direction of the White Tower, he smiled: "Here, you must no longer feel the dryness in the desert."

He smiled mysteriously: "We used to think that no matter how hard we tried in the desert, a gust of dry wind could take away all the moisture in the air.

"But our results have changed the previous cognition, when enough plants are planted in the desert.

"Their respiration can change the climate of the desert to a certain extent.

"Just like the example of soil erosion I just mentioned, when the vegetation that can adjust the water resources of a region comes back, the climate of the whole region will become healthier."

Lu Qingfeng asked curiously: "But this is also a 'chicken and egg' concept. How can there be enough plants in the desert? Can it produce respiration that changes the climate of the desert?"

Qi Guanglu pointed to the white tower in front: "That's it. We call it a small ecological adjustment system. Although it has yet to be perfected, you have also seen that it has created an oasis."

Jiang Yu looked at the White Tower and asked curiously: "What is its working principle?"

Qi Guanglu answered with a smile: "Do you still remember the plans proposed by our water transportation team 12 years ago?"

Jiang Yu nodded: "I roughly remember."

"The plan to build a climate regulator in space was abolished five years ago." Qi Guanglu said: "This plan is too advanced, and the theoretical and technical resistance is too great.

"So we put all our energy into the plan of the hydration system.

"It was inspired by artificial starch, and although it is difficult to transport water, it is relatively easy to transport the hydrogen and oxygen that make up water.

"This is thanks to the huge investment in Moon City, which designed a special train for us to resist pressure and refrigeration, and built a railway of more than ten kilometers, so that liquid oxygen and liquid hydrogen can be directly transported here from the sea.

"This special train runs once a day and can transport thousands of tons of liquid hydrogen and liquid oxygen at a time."

Jiang Yu and others looked at the circles of small holes in the White Tower and roughly understood how the system works.

Qi Guanglu continued to explain: "If it is more than 1000 tons of water, it is a drop in the bucket, but it is different to transport liquid hydrogen and liquid oxygen separately.

"In the liquid state, they are equivalent to compressed hydrogen and oxygen, with a higher density and a large one-time carrying capacity, while liquid water is difficult to compress.

"We have a hydrogen production plant and an oxygen production plant in Qinhuangdao, which directly use seawater to produce hydrogen and oxygen, and then transport them here.

"After adding liquid hydrogen and liquid oxygen to the small ecosystem in proportion, the two liquid gases are first gasified and then synthesized into water vapor through reaction.

"Water vapor is released from these small holes and spread evenly to the surrounding vegetation."

Jiang Yu nodded, he was more concerned: "How about the cost?"

Qi Guanglu smiled and said: "The water transportation team has made relevant technical breakthroughs, especially hydrogen production technology, because nuclear tests in space now require a lot of hydrogen.

"This has greatly improved the efficiency of the hydrogen production industry, and at the same time reduced the cost a lot.

"The liquid hydrogen we use does not require further purification, and the oxygen production process has already been perfected.

"The electricity generated by wind energy and solar energy in the test field is enough to convert liquid gas into liquid water.

"Generally speaking, it is difficult to pay back the cost of this common crop, so now we are cultivating some economic crops.

"However, the significance of this system is indeed extraordinary, and it has completely ended the difficult, costly, and easily repeated problems of sand control in my country since the last century.

"If there is enough money, there will be no more deserts in the country, and even the world will no longer have deserts!

"Human arable land has doubled, and there will be no more sandstorms!

"We have mastered the way to transform the earth! This is a great progress for human civilization!"

Qi Guanglu joked: "At that time, we must pay attention not to increase the global oxygen content as a whole."

Jiang Yu squatted down and touched the green grass beside the White Pagoda. The green grass grew so thick that the sand below became compact.

The green grass covers the sand below, and the vitality covers the barrenness.

He asked, "How big is the test field now?"

"Nearly [-] mu." Qi Guanglu replied: "This is a relatively early batch of experimental fields, mostly crops, and there are some forests with well-developed roots in the north.

"We found that [-] mu is probably the dividing line for improving the local climate. The local climate below will not change much, but above it will be significantly improved."

Jiang Yu smiled and said: "This system has another huge use. When it is further matured, it can change the environment of the planet!"

　I'm sorry, I just saw that the recommendation ticket has reached the standard for updating. I don't have time to write today. I will put it tomorrow for adding the recommendation ticket.

　　Ask for a monthly ticket and a recommendation ticket.
