Two days later, Zhang Wei walked out of the scientific research building with two robot bodyguards equipped with weapons, drove a bulletproof flying car, and went to the capital to attend a food strategy meeting.

After arriving, staff immediately greeted him and led him to the meeting site. Along the way, almost everyone greeted him with smiles on their faces. He also responded enthusiastically, although he did not have any know!

After arriving at the meeting site, Zhang Wei is still the protagonist of the stars, and he is a well-deserved focal point. There is no way, Zhang Wei has such a big influence in the country now, even if he wants to keep a low profile!

Not long after, the meeting officially started, and the participating experts offered their ideas and suggestions, and various plans emerged one after another.

Some experts said that we should use the current influence of the country to carry out food diplomacy to ensure the supply of the world's major food countries to us.

Some experts said that it is necessary to research higher-yielding crops, and at the same time increase research and development efforts in chemical fertilizers and other production factors to ensure a steady increase in grain yield per mu.

Some experts said that it is necessary to increase the intensity of purchasing agricultural land overseas, grow food overseas, and then transport it back to China.

Some experts say that the current space technology is developed enough that it is possible to install countless huge mirrors with strong light reflection ability in space to reflect the sunlight in space back to the earth and prolong the illumination time of crops. Plants produce nutrients through photosynthesis, and transport nutrients to the top of the plant. Extending the light time can increase the photosynthesis of plants and increase the yield. Moreover, these mirrors installed in space have many uses, such as keeping the city in 24-hour light to create a real city that never sleeps; reflecting enough light to the cold north to turn the north into a cool autumn or a hot summer; It can even be used as a weapon. Countless mirrors can reflect sunlight to a certain city in an enemy country at the same time, allowing the city to withstand the power of nine suns or even eighteen suns at the same time. This is definitely a strategic weapon.

...

Zhang Wei felt very speechless, everyone considered almost all the plans that could be considered, and the plans he was going to propose were also mentioned in advance by everyone, so that he had no plans to propose.

Fortunately, he still has something to do, because he still has the status of a consultant in this meeting, responsible for evaluating the feasibility of each plan from a technical perspective, and making a score. For the assessment he gave, the chief and others attach great importance to it, because he is the well-deserved first person in the scientific world!

The meeting lasted for two days, and finally formulated a huge food strategy, food diplomacy, overseas purchase of agricultural land and other measures in parallel, and the seawater transfer project to the west was also determined to be fully implemented. As for installing mirrors in space, this mind-blowing plan has been put on hold for now.

That night, "News Network" reported the matter in detail, which immediately aroused heated discussions.

"This food strategy is very necessary. Since the beginning of this year, global natural disasters have occurred frequently, and food crises will inevitably break out. According to expert analysis, this situation may become the norm in the future. Affected by this, food prices will definitely continue to rise. We You have to prepare early."

"We really need to pay attention to the food problem. People can not play Deep Blue 1 for a month, but they can't go without food for a day. Our country has such a large population. Once a food crisis occurs, even if we can buy food from abroad, it must be expensive. Don't Overestimating the conscience of capitalists. A few years ago, even things like garlic and salt could be fried n times, and a bowl of instant noodles could be fried for 50 when there was a traffic jam on the highway. The production cycle of food is so long and there is no substitute. There is a gap, people are about to starve to death, a catty of rice is two hundred yuan, do you want to buy it or not?"

"During the Spring and Autumn Period, the Prime Minister of Qi State, Guan Zhong, ordered the people of the country to wear silk and spent a lot of money to buy it from the silk-producing countries of Lu and Liang. On the one hand, the wearing of silk was prohibited, and on the other hand, the sale of grain was prohibited. Soon after, there were countless hungry people in the two countries, and Lu Liang was subordinated to Qi State and fell.

Food issues must be taken seriously. "

"Wasn't the westward sea diversion project proposed a long time ago, and then it was considered unfeasible? Why is it proposed again now, and it is fully implemented? Is this reliable?"

"It is undeniable that if the seawater diversion project succeeds, it will bring unimaginable returns to our country. Taking Xinjiang as an example, the area of ​​plain oases suitable for human survival is less than 4.2% of the total area of ​​Xinjiang's 1.66 million square kilometers of land. , if the sea water transfer project to the west is really successful, this land of more than one million square kilometers will become a land suitable for human survival!

However, from a rational point of view, the westward transfer of seawater seems to be unreliable, and the seawater should be desalinated first, and then introduced to Northwest and North China. The cost is too high! If we want to achieve the goal of "controlling my country's deserts and sandstorms, and completely changing the poor ecological environment in North and Northwest China", based on Xinjiang's average annual precipitation of 155 mm and evaporation (optimistically estimated at 50), at least 49.6 billion cubic meters will be needed Sea water flows in. Raising the Bohai Sea to an altitude of 1280 meters requires about 6.4 kilowatt-hours of electricity, and the total power consumption will reach 317.44 billion kilowatt-hours, which is equivalent to four times the annual power generation of the Three Gorges Project in 2008 of 80.8 billion kilowatt-hours.

In addition, the cost of seawater desalination must be calculated. The current mainstream seawater desalination technologies are mainly reverse osmosis, multi-stage flash evaporation and low-temperature multi-effect. Among them, reverse osmosis has the lowest operating cost. Plus the cost of chemicals is about 0.5 yuan/ton of fresh water (related to the pretreatment process), and the direct operating costs are these two. The electricity price adopts the industrial electricity price, the peak power is about 1.0 yuan/kWh, the valley power is about 0.5 yuan/kWh, the average electricity price is 0.7 yuan/kWh, and the direct operating cost per ton of water is about 3.3 yuan. If labor costs, maintenance, reverse osmosis membrane replacement and other costs are considered, the operating cost (excluding depreciation) is generally 45 yuan per ton of fresh water.

All in all, the project volume is too large and the cost is too high. With the current level of technology, it is simply a science fiction theme! "

"Anti-gravity flying cars have appeared, intelligent robots have appeared, and our country is about to land on the moon. These are all sci-fi. Compared with the westward diversion of sea water, it is nothing at all. I think it is worth trying! Maybe the country has mastered it. How about a technology that we don’t know about that can reduce costs on a massive scale?”

Regardless of the reaction from the outside world, the food strategy was launched soon, and the seawater diversion project to the west was officially launched. At the same time, major coastal cities short of water have also started construction of a large number of seawater desalination plants, and the entire country has become a giant. construction site.

While these construction works were going on vigorously, the first spacecraft of Future Technology Company was officially completed! ***book*** (Sikushu)
