Chapter 254 (2/2)
The second way is to transform the land that is not suitable for planting crops into the land that is suitable for planting crops.
Experts once had relevant ideas: ”sea water is lifted from the northwest coast of Bohai Sea to an altitude of 1200 meters, to the southeast of Inner Mongolia Autonomous Region, and then along the east-west direction of the 42 ° line of north latitude to the surface of the trough, passing through Yanshan and Yinshan to the north, leaving Langshan to the West and entering Juyan sea, bypassing the rest of Mazong mountain and entering Xinjiang. The terrain of Xinjiang is higher in the East and lower in the West. After entering Xinjiang, the sea water can form self flow. Then, the natural river course of Shule River ”flowing from the east to the west” is used to flow into Lop Nur, the eastern margin of Tarim Basin
This is the project of ”sea water transfer to the west”. It is supposed to fill the dry salt lake, salt lake and closed structural basin in the desert with a large amount of sea water to form man-made sea water river and lake, so as to suppress the desert. At the same time, a large number of sea water rely on the abundant solar energy natural evaporation in the northwest to increase rainfall as the water and gas supply source of wet to wet northern climate, so as to achieve the goal of controlling China's deserts and sandstorms and completely changing the poor ecological environment in North and Northwest China.
When this idea was first put forward, it aroused a wide debate and query from the national public opinion, which has not yet subsided. Some people even ridiculed it as a joke like ”tiling the Great Wall”.
In fact, there were many shortcomings in this assumption at that time. The main reason was that the cost of the project was too high, and the cost of transporting seawater was too high. In addition, there was a large-scale land salinization risk when seawater entered the inland.
However, with the small nuclear fusion furnace technology provided by Zhang Wei, i.e. the success of controlled nuclear fusion, all these problems are not problems.
As we all know, helium-3 is the raw material of nuclear fusion. Every kilogram of helium-3 burned can produce 19 megawatts of energy. 100 tons of nuclear fuel helium-3 can meet the energy demand of the whole year on earth. However, the capacity of chang'e-7 spacecraft that is being manufactured by the state exceeds 500 tons. That is to say, as long as chang'e-7 transports helium-3 to the moon once, it can meet the energy demand of the earth for five years We can also see from these data that as long as nuclear fusion power plants are widely used, the cost of electricity will inevitably be reduced to an appalling level.
With such a low cost of electricity, the cost of desalination will also be greatly reduced. After desalination, fresh water can be introduced into North and Northwest China to control deserts and sandstorms and completely change the harsh ecological environment in North and Northwest China. The whole construction work of the project can be completely constructed by intelligent robots, which do not need wages, only need cheap power and energy, and can work 24 hours without complaint, with strong working ability, which can greatly reduce the cost of the project. As for the cost of transporting water, according to the calculation, raising a ton of water to 1280 meters above sea level requires 6.4 degrees of power consumption. This cost is a little high in the past, but it is not worth mentioning now.
Therefore, the project of ”sea water transfer to the west” can be fully implemented now.
Not only that, the project can be expanded. There are eight deserts from east to West in the north of China. They are Horqin, Hunshandak, Maowusu, Kubuqi, Ulan Buhe, Tengger, Badain Jilin and Taklimakan deserts. In the past, we didn't have a big way to take these deserts, but now we can completely break the traditional mindset and make full use of the vast water of Bohai Sea to transform all these deserts into cultivated land or residential areas, which is equivalent to adding several provinces of land to the country. With such a large amount of land, the country's population will be more than one billion, and its food will be fully self-sufficient, which is totally beneficial to thousands of people The feat of autumn.
In addition, China can build a large number of desalination plants to provide cheap fresh water and completely solve the problem of water shortage faced by major cities in China.
It has to be said that with the technology of small nuclear fusion atomic furnace provided by Zhang Wei, many ideas that seemed to be difficult to realize in the near future, or that seemed to be wishful thinking by many people, can be implemented now. This is the power of technology, and this is the change brought about by Zhang Wei.
Zhang Wei said he was calm about this. Compared with the star transformation he was going to carry out in the future, these projects are just small cases. (to be continued. )
