The sand that can be seen everywhere on the earth, will this material be a scarce resource?

Zhong Guoqiang said seriously: "The sand Han Yuxin mentioned is construction sand."

"Yes." Han Yuxin said worriedly: "It's construction sand, and now it is starting to become in short supply."

It was a long story, and one or two words were incomprehensible. Then, she took the two of them to a nearby teahouse to sit down.

Near the window, Chen Yao, Han Yuxin and Zhong Guoqiang sat down, and the waiter filled the three of them with three cups of black tea.

Han Yuxin took a sip of tea and said slowly in a tone: "Senior Brother, do you know that the sand in the ocean and the sand in the desert cannot be used as building materials, right?"

Of course, Chen Yao knew that if he studied physics seriously in middle school, he would know the reason.

30% of the earth's land is desert. Not only can the desert not be used for cultivation, it wastes land resources, but it will also cause sandstorms to pollute the environment.

For any country in the world, controlling deserts is a headache.

Someone once suggested that desert sand be used as building materials and transported to urban construction buildings, urban pavements, and desert problems will be solved?

However, desert sand cannot be used as building materials. It is weathered, with too small particles, too poorly bonded to concrete, and also contains alkaline substances.

The sand used in construction is river sand, which is thicker and relatively round, and is the best material for building sand.

However, naturally formed sand is very long, and stones are washed and separated from the rivers, which takes thousands of years to form a large amount of river sand.

Due to over-exploitation, the sand in many rivers has been mined and is becoming increasingly scarce.

It also affected the river ecology, and the country began to ban illegal sand mining.

The river sand is getting less and less, so the sea sand is the sea sand. 70% of the earth is the ocean, and the ocean has endless sand.

However, the salt content of sea sand is too high, and the salt will corrode and the building will easily collapse over time.

The sand in the desert cannot be used, and the sand in the ocean cannot be used. It seems that there is only river sand, but it is becoming increasingly scarce.

In the 1980s, a ton of sand in China cost only 2 yuan, and it doesn’t even cost money. You can just pull a car back to a nearby river.

In 2000, it was only 10 yuan per ton, and in 10 years it was only 15 yuan per ton. However, since 2018, the price of sand began to soar, rising to 140 yuan per ton, a surge of 1,000%!

Yes, one thousand percent.

The rise is faster than gold and diamonds, who would have thought that sand will become a scarce resource one day.

Professor Zhong Guoqiang slowly talked about the sand while drinking tea, but Chen Yao didn't say anything and listened to him.

In fact, there is not a small amount of sand in China. After all, there is sufficient rivers. However, if the demand is too high, it becomes a shortage of voluntary voluntary.

The annual sand consumption in the world exceeds 40 billion tons, accounting for half of the country, about 20 billion tons. However, the natural river sand formation is very long, and the mining volume has exceeded the speed of natural formation.

There are less and less sand in high-quality buildings, but the country still needs to build it, and it needs to be used to build houses, bridges, urban pavements, etc.

Seeing the price of sand soaringly, there was no other good way.

Although there is a technology that can use machines to crush stones, that is, artificial sand making, the cost is not low and it is not a long-term solution.

What if the stones are mined for one day?

The mining of tens of billions or tens of billions of tons every year is not a joke, and one day the stones will be dug up.

Legend University is now facing such a difficult problem. The price of sand suddenly soared and exceeded the budget and had to stop working.

Chen Yao touched his chin and thought for a while, and said, "It is definitely not a long-term solution to form just by nature."

This is certain, it takes thousands of years for nature to form, and many rivers have been dug up.

"Artificial sand making is a good way," said Han Yuxin.

Chen Yao shook his head slightly: "It is not a long-term solution. The best way to use desert sand to solve the shortage of sand. Secondly, it can also control sandstorms."

It’s simple to say, it’s not that easy to transform desert sand into building sand. Perhaps technology is not the main reason, and the most difficult one is the cost.

Technology research and development does not solve the cost, it will always be just a niche and cannot be used on a large scale.

70% of the world's freshwater resources are in Antarctica. Transporting the ice from Antarctica to the desert can solve the shortage of water resources there. However, the cost is too high and it is difficult to achieve.

Therefore, if we want desert sand to be really used by humans and used as building materials, in addition to solving technical problems, we also need to solve cost problems.

"Senior Brother, do you really have a way?" Han Yuxin was very curious.

If he really does it, it will be a great thing of great merit. You can win the Nobel Peace Prize!

Chen Yao nodded with a smile: "There must be a solution."

Regardless of whether the remaining dormitory buildings can be completed or not, the construction notebook of Legend University can be completed and enrolled students can be started.

The hardware is fine, and it has reached the level of a top university. The biggest problem is software, especially teaching talents.

Chen Yao asked Zhong Guoqiang: "Professor, I want to invite you to be the dean of the School of Artificial Intelligence at our school. Are you willing?"

As a famous domestic artificial intelligence scientist, he has a high status in the science and technology industry. If he can join in, he can enhance the school's teaching strength.

Zhong Guoqiang said: "I want some time to think about it."

After thinking about it, he added: "No matter whether I join or not, I will introduce talents from home and abroad to teach in your school."

In addition to artificial intelligence, there are also many cutting-edge disciplines such as brain wave applications, large-scale circuit integration, software and Internet, and a considerable number of teachers are engineers from legendary trajectories.

After graduation, you can enter the legendary trajectory and work, which is quite attractive to students. After all, you can get a monthly salary of 30,000 yuan when you join the company, and not all companies can offer it.

Unlike other traditional universities, this university will adopt more advanced teaching methods to train at least one of two or three Nobel Prizes, physics, chemistry, and medicine.

In the long run, let it become a cradle of top talents and contribute to the country's basic teaching cause.

After a while of discussion, the matter was determined. As for the technical issues of desert sand transformation, Chen Yao will find another way to solve it.

Zhong Guoqiang put down his teacup, stood up and went back to Shenzhen University to attend class immediately.

Chen Yao paid and walked out of the teahouse with Han Yuxin. It was sunny outside, and the cool breeze was very comfortable on his body.

She scanned the vast university campus around her: "Senior brother, I think you have a great ambition to start a university."

Chen Yao smiled and asked back: "What ambition?"

Han Yuxin said: "You want to be the principal of the world's number one institution!"

Since university is called legend, you must be worthy of this name.
