Ching Hai Lake.

This is the largest inland lake in China and the largest saltwater lake in the country, formed by the fault collapse between Datong Mountain, Riyue Mountain and Nanshan Mountain in Qinghai in the Qilian Mountains.

Qinghai Lake is located on the plateau, the average daily temperature in July and August is about 15 degrees Celsius, at this time it is also the most beautiful time of Qinghai Lake, thousands of acres of talented flowers around the lake are blooming, the blue periphery of the blue waves is scattered with golden bright yellow, the wild flowers of the alpine pasture are colorful, such as silk, countless cattle and sheep are fat and strong, dotted in the meantime.

An 11-member team of the Kunpeng Project set off in July.

The purpose of their visit was to investigate the current comprehensive environment, especially the environmental data of the lake bottom.

In the blink of an eye, it was already the end of the year.

Seven or eight working tents have been erected along the shores of the lake, and the most striking thing is the temporary signal station.

"Brothers, don't make a mistake, otherwise this year will only be spent here, Xiao Liu, go get something to eat, the meal is almost here." A huge work tent, the leader of the investigation team supervised everyone.

At about 11 o'clock in the morning, I saw two staff members driving an off-road vehicle and leaving the workplace, which was very remote, and there were no people who settled down nearby, and it took two hours to find a local place to live and buy food.

But even in December, they can occasionally see some tourists, and they also see a lot of road trips, and even curious people come to them to ask for directions or something.

Although the conditions are very difficult, it is also a pleasure to be able to get away from the hustle and bustle of the big city and be in the company of nature, but daily life is not very convenient.

At the same time, there were three people standing in the center of the lake, and there were a lot of equipment on the surface of the ice powder, and at the same time, they were also swaying from time to time to dig out ice holes to prevent them from freezing.

In winter, Qinghai Lake freezes and freezes in December every year, and the lake cannot be opened until the end of March.

After a while, two staff members in wetsuits surfaced one after another, and the staff on the lake immediately pulled them up.

"The measuring equipment has been put in the designated position, and this is the last time, so hopefully it won't go wrong."

On the other side, the organization of the expedition team also drove away with two assistants, drove three kilometers to the destination, and the team leader held a paper map in one hand and took a sip of the plateau auxiliary breathing apparatus hanging on his body with the other hand.

I've been here for more than half a year, but altitude sickness still makes him feel a little powerless, but he has survived most of the year.

Fortunately, working in such a difficult environment, the company gave impeccable treatment, and everyone who came to work here was offered an additional five times their usual salary, and the bonus was doubled.

"Boss, the final measurements are out, and most of the annual sunshine hours around the lake area are more than 3,000 hours, which is about 700 hours higher than the latitude east of Qinghai. The annual sunshine percentage reached 68~69%, and the total annual radiation was 171.461~106.693 kcal/cm²·year, which was 10~40 kcal/cm²·year higher than that of the North China Plain and the Loess Plateau at the same latitude. ”

The team leader nodded, looked at the vision in front of him and couldn't help but say: "The terrain of this area is flat and open, the area is large enough, yes, this is the best location for laying solar mirrors." ”

The power supply of the underwater data center at the bottom of Qinghai Lake will be an independent system, yes, it will be powered by solar power, and it will be 100% natural and pollution-free.

In order to make the underwater data center work here, Bluestar Technology has developed a solar tower power generation system, also known as a centralized system, which is a large area of the site with many large solar mirrors.

In technical terms, it is called a heliostat, that is, each pigeon is equipped with a tracking mechanism to accurately concentrate the sun's light on a receiver at the top of a tower, like a sunflower.

Hosted by artificial intelligence, once built, there is basically no need for anyone to manage it.

The concentrating rate on the receiver can be more than 1000 times, where the absorbed sunlight is converted into heat energy, and then the heat energy is transmitted to the working fluid, and then input into the thermal power machine through the heat storage link, which expands and works, drives the generator, and finally outputs it in the form of electrical energy.

It is mainly composed of concentrating photonic system, heat collection subsystem, heat storage subsystem, and electron system.

The solar power tower, which is mainly used for the power supply of the Qinghai Lake bottom data center, is codenamed PS09, and the solution to the power supply problem was discussed after the Qinghai Lake underwater data center was determined, so it was developed by the way, with an investment cost of about 1.12 billion yuan.

Then, the engineers of the "Kunpeng Project" found that they had accidentally made this thing the technological boss of the industry, and then found that this thing also had good commercial prospects.

The person in charge of the "Kunpeng Project" swore that he had absolutely no other ideas, but just wanted the data center at the bottom of the lake to have electricity.

In August this year, a salesman from Bluestar Technology went to Europe to promote the solution of commercial solar power plants, and the Spanish power company showed strong interest in it.

As for why it can accidentally achieve the status of the industry leader, the lens Bluestar Technology has successfully invested in R&D, the sunshine collector is also the successful R&D and design of Bluestar Technology's own investment, and the electric tower is still the successful R&D and design of Bluestar Technology.

Each mirror has an area of 150 square meters and concentrates sunlight on the top of the 247-meter tower.

This so-called solar power tower is, to put it bluntly, a way to boil water.

Today, Bluestar Technology Group is no longer an Internet technology company that simply sells advertisements since the day of All in cloud computing services.

The astronomical figure of more than $10 billion in annual R&D investment is false.

In the field of solar photovoltaic industry, Bluestar Technology is also inexplicably at the forefront, and the technology has been developed, and there is no reason not to use it commercially.

Huawei is one of its partners, some of Huawei's communication base stations need photovoltaic power generation in remote areas, and we found that Bluestar Technology can provide excellent solutions here.

Needless to say, let's cooperate.

"Boss, come back and eat when the meal is ready!"

"Got it."

……

Half an hour later, in a work tent.

Three or five people sit around at random, everyone is working while eating, or discussing something, where the people are, where the restaurant is, where the work is, in this difficult environment there is not so much attention.

I saw an engineer staring at the panel data on the computer screen and said: "The measurement statistics show that the temperature in the east and south of the lake area is slightly higher, with an average annual temperature of 1.1~0.3 degrees Celsius; The northwest and north are slightly lower, the average annual temperature is between minus 0.8~0.6 degrees Celsius, the average maximum temperature is between 6.7~8.7 degrees Celsius, the average minimum temperature is between minus 6.7~4.9 degrees Celsius, the extreme maximum temperature is 25 degrees Celsius and 24.4 degrees Celsius, and the extreme minimum temperature is minus 31~minus 33.4 degrees Celsius. ”

The team leader present took a bite of the roast mutton and said, "What about the moisture?" ”

Hearing this, the engineer who had finished eating quickly typed on the computer for a while, stared at the panel and said: "The annual precipitation in the lake area is less, but the east and south are slightly higher than the north and west, the annual precipitation in the east is 412.8 mm, the south is 359.4 mm, the northwest is 370.3 mm, the west is 324.5 mm, the annual evaporation reaches 1502 mm, the evaporation far exceeds the precipitation, the precipitation in the lake area changes seasonally, and the tax reduction is mostly concentrated in May ~ September." ”

The team leader asked, "What about the winds and sandstorms?" ”

But for a moment, the engineer dropped out of the data and reported: "The number of windy and sandstorm days in the lake area is one of the more areas in the province, and the prevailing northwest wind, due to the high altitude of the lake area, the west wind in the lake is more, and the high air has a great impact, and the whole year is mostly under the control of the west wind, but the spring breeze speed is the largest, under the action of the wind, the general wave is 2~3, the maximum is 7~8, and the number of days above 6 waves throughout the year is about 40 days." ”

Finally, the team leader asked, "Is there any data on the water temperature and ice conditions of the lake?" ”

"The highest temperature in August was 22.3 degrees Celsius, the average was 16 degrees Celsius, the underwater average was 9.5 degrees Celsius, and the lowest was 6 degrees Celsius, and the data just measured showed that the temperature in the upper layer of the subglacial lake was minus 0.9 degrees Celsius, and the bottom water temperature was 3.3 degrees Celsius," the engineer reported. In terms of ice conditions, the ice sheet of the whole lake new city began to stabilize in the first half of the year, the ice period is expected to be 108~116 days, the shortest historical data is 76 days, the longest is 138 days, the thickness is generally 40 cm, the maximum thickness is 90 cm, the maximum iceberg volume is about 10 cubic meters, and the indoor ice is expected to completely melt in mid-April. ”

The team leader nodded, took a new piece of roast mutton and said, "Tossing around in this wilderness for more than half a year is to get the data you reported, pack it and send it back to the headquarters." ”

At this time, another staff member suddenly said: "By the way, when you went out just now, a few people claiming to be from the Geological Bureau came to us. ”

The team leader asked, "What's the situation?" ”

The staff member said: "It seems that they know that we are working on hydroclimatology and climatology here, and hope that we can make a copy of the latest data and share it with the state." ”

Hearing this, the team leader suddenly said: "Playing the piano indiscriminately, the budget of our inspection team is more than 27 million, these precious data are the company's assets, and we don't have the right to decide to hand over the data, let them go to the company to talk, and the information is locked up, don't be secretly downloaded." ”

"Haha, don't worry, it's been uploaded to the company's cloud, and there's nothing left here, unless someone from them can break through the security system of the Nebula Star-Cloud."

"Shocking...... There are three days left to call it a day and go home, and if you want to go home early to hug your wife and children, don't make any moths at the last moment. ”
