That night, news broadcast reported the incident in detail, which immediately caused a heated discussion.
”This food strategy is very necessary. Since this year, there have been frequent global natural disasters, which will inevitably lead to food crisis. According to the analysis of experts, this situation may become normal in the future. Affected by this, food prices will definitely continue to rise. We must prepare as soon as possible.”
”We really need to pay attention to the problem of food. People can not play dark blue 1 for a month, but they can not eat for a day. There are so many people in our country. Once there is a food crisis, even if we can buy food from abroad, it must be a high price. We must not overestimate the conscience of capitalists. In the past few years, even garlic and salt can be fried n times. When there is a traffic jam on the highway, a bowl of instant noodles can be fried to 50 times. The production cycle of grain is so long and irreplaceable. Once there is a large-scale gap, people will starve to death. A Jin of rice costs 200 yuan. Do you want to buy it or not? ”
”In the spring and Autumn period, the Prime Minister of the state of Qi, Guan Zhongling, ordered the people of the state of Lu and Liang to wear silk, and spent a lot of money to buy silk from the silk producing state of Lu and Liang, raising prices, so that the people of Lu and Liang could plant mulberry and sericulture instead of rice. After that, the state of Qi banned the wearing of silk and the sale of grain on the one hand. Soon after, there were countless starving people in the two countries. Lu Liang returned to the state of Qi and died. The state of Qi did not move its swords and soldiers. This is the warning given to us by history. We must pay attention to the food problem. ”
”Didn't the project of transferring the sea water to the west come up long ago, and then it was considered infeasible? How can it be put forward now and implemented in an all-round way? Is it reliable? ”
”It is undeniable that the success of the project will bring unimaginable returns to our country. As for Xinjiang, the area of 1.66 million square kilometers of land is less than 4.2% of the total area of the plain oasis suitable for human survival. If the project of water transfer to the west is successful, the land of more than 1 million square kilometers will become the land suitable for human survival!
However, from a rational point of view, it seems that the West Water Diversion Project is not very reliable, and it is also too expensive to desalinate the sea water first and then introduce it to the northwest and North China! If we want to achieve the goal of ”controlling deserts and sandstorms in China and completely changing the ecological environment in North China and Northwest China”, we need at least 49.6 billion cubic meters of seawater inflow according to the average annual precipitation of 155 mm and evaporation < in Xinjiang. It will take about 6.4 kilowatt hours to lift the Bohai Sea water to 1280 meters above sea level, and the total power consumption will reach 317.44 billion kilowatt hours, which is 4 times of the 80.8 billion kilowatt hours generated by the Three Gorges Project in 2008.
In addition, the cost of desalination should also be calculated. At present, the mainstream desalination technologies are mainly reverse osmosis, multi-stage flash evaporation and low temperature multi effect. Among them, the operation cost of reverse osmosis is the lowest, and the average power consumption per ton of water is about 4 degrees. In addition, the chemical cost is about 0.5 yuan / ton of fresh water, and the direct operation cost is these two kinds. The industrial electricity price is adopted for electricity consumption, with peak electricity of about 1.0 yuan / kWh, valley electricity of about 0.5 yuan / kWh, average electricity price of 0.7 yuan / kWh, and direct operation cost of about 3.3 yuan per ton of water. If labor, maintenance, reverse osmosis membrane replacement and other costs are considered, the operation cost is generally 4-5 yuan / ton of fresh water.
All in all, the project volume is too large and the cost is too high. In terms of the current level of science and technology, it's just science fiction! ”
”With the emergence of anti gravity flying cars and intelligent robots, our country is about to land on the moon. These are very science fiction. Compared with the sea water transfer to the west, they are nothing. I think it's worth trying! Maybe the country has mastered technologies that we don't know, and can reduce costs on a large scale? ”
No matter what the reaction from the outside world, the food strategy was soon launched, and the project of water transfer from the west to the East was officially started. At the same time, a large number of desalination plants have been built in many coastal cities with water shortage, and the whole country has become a huge construction site.
While these construction works are going on vigorously, the first spaceship of future technology company is officially completed! (to be continued. )
