After Liao Bin left the presidential palace, he visited many other powerful figures in Angola one after another, which is nothing more than sending flying cars and money to open the way, plus the land that Qingquan Science and Technology wants is indeed the most barren Namib Desert, in the name of scientific research experiments, and promised to help Angola to carry out desert greening for free after the results are produced in the future.

Within a few days, Liao Bin received the consent of the Angolan government, and the two sides officially signed a cooperation, Qingquan Technology exchanged 10 billion US dollars worth of new seeds for the right to use 1,000 square kilometers of land on the Atlantic coast of Namib for 30 years, which was used as a scientific experiment to study the technology of controlling the arid desert!

For the Angolan government, pie is falling in the daylight! A broken desert, nothing can be exchanged for 10 billion US dollars of new seeds, a few powerful people in power, everyone's pockets will bulge in an instant, not to mention that these are still new energy trees that can provide a source of income for a long time!

Moreover, Qingquan Technology is also very good, and every person in power in Angola has sent an atmospheric and beautiful "Shengshi Datang" flying car, plus an activity fund that is not known to the outside world!

For Qingquan Technology, the real cost is not much, 10 billion US dollars of seeds are just seeds, not cash, as for the cost of seeds, so it has been reduced to a very low level! What really needs to be spent on cash is to open the way for those in power!

It didn't cost much money to get a piece of land, although the agreement is written with a 30-year right to use it for desert management research, but when it really comes to the hands of Qingquan Technology, it is not so simple, this is the most important retreat base that Qingquan Technology is ready to use!

1,000 Hercules cargo transport flying cars are fully loaded with goods, which can transport millions of tons of materials at one time; 10,000 flying cars with the surname of 10,000 families transported all the construction workers in charge of construction at one time.

This time, Qingquan Technology set up its own construction company, recruited construction workers, technical personnel, etc., and now the overall environment is still not good, there is a surplus of talents in the construction industry, and Qingquan Technology has found all kinds of talents with a casual move.

Mo Qingming stopped his "Shengshi Datang" flying car, and as soon as he flew around, a hot wave hit, and the golden desert was like a wave, forming countless beautiful crescent moons.

It's unusually desolate, only near the sea are some desert plants, cacti, etc., and other creatures are not visible at all, maybe some desert snakes, scorpions, etc., but most of them are hiding in that hole at this time.

The sea is very clean, blue, and the cloudless blue sky corresponds to the sky, as if it is a reflection, which makes people's hearts open, there is a bookish atmosphere, scolding Fang Xuan, pointing to the heroic spirit of the country!

"How? This is a good plot, isn't it? Liao Bin saw that Mo Qingming was in a daze, came over and patted him on the shoulder and said with a smile.

"You are embarrassed to say that more than 100 billion US dollars have been exchanged for this barren land, and the company does not know how much money to invest here to build a similar base! The barren land is still uninhabited and spent! Mo Qingming shook his head.

He was really not very satisfied with this place, it was all desert area, there was nothing, it was too desolate!

"What I want is a barren and inhabited barren land, how did the boss explain it to me at the beginning, and now that the world has been carved up, only such a place can make our company make a big move, otherwise where can we hide it!" Liao Bin also shook his head, there is no way, if the company wants to develop, it is natural to get rid of various restrictions from China.

But all the lands of the earth already have owners, even the Antarctic ones have owners, uh, they are penguins! No matter what country the company goes to, it will be subject to various restrictions, and it can only find a backward country, find a barren land, and slowly develop!

"Yes! But then again, building a huge base in such a desolate place is also a huge achievement! Mo Qingming smiled very sullenly, for everyone at Qingquan Technology, everyone is a young person, what are you afraid of!

"Let's take it step by step, the first thing that the future base needs to solve is the problem of water, there is nothing without water, we are useless if we have great ability!"

That's right, this base was named the future, the future base by the people of Qingquan Technology!

"Didn't you see the company lining me? Rest assured, our material company has already developed a variety of new materials for seawater desalination, plus other new seawater desalination technologies, this place will be flooded in the future! Mo Qingming smiled proudly.

Liao Bin is not engaged in technology, he is responsible for sales, he doesn't understand technology at all, and he can't help but be a little curious!

"Tell me about it!"

With Mo Qingming's slow introduction, the desalination technology was fully displayed in front of Liao Bin.

Desalination is the use of seawater desalination to produce fresh water. It is an open-source incremental technology that realizes the utilization of water resources, which can increase the total amount of fresh water without being affected by time, space and climate, and can ensure a stable water supply such as drinking water for coastal residents and water supply for industrial boilers.

The process of obtaining fresh water from seawater is called seawater desalination, and the seawater desalination methods used now include seawater freezing method, electrodialysis method, distillation method, reverse osmosis method, and ammonium carbonate ion exchange method that can achieve profitability, and the reverse osmosis method of reverse osmosis membrane is used to quickly occupy the market with its advantages of simple equipment, easy maintenance and equipment modularization, and gradually replace the distillation method to become the most widely used method.

There are more than 100 scientific research institutions in more than 10 countries in the world that are conducting research on desalination, and there are hundreds of desalination facilities of different structures and different capacities in operation. A large, modern desalination plant can produce thousands, tens of thousands, or even nearly a million tons of fresh water per day.

The cost of water is decreasing, and in some countries it has been reduced to about the same price as tap water, and in some areas the amount of water desalinated has reached the scale of national and municipal water supplies.

Now the world's mainstream seawater desalination technology is mainly the traditional distillation method (thermal method) and reverse osmosis method (membrane method) two categories, of which low multi-effect distillation, multi-stage flash evaporation method and reverse osmosis membrane method are the world's mainstream technologies, distillation method is currently the most widely used, with the advantages of low seawater pretreatment requirements, high quality of desalinated water, etc., the disadvantage is serious energy consumption, dirt is difficult to treat!

The reverse osmosis membrane method has the advantages of low investment and low energy consumption, but the requirements for seawater pretreatment are high, that is to say, when using the reverse osmosis method for seawater desalination, some treatment of seawater should be carried out in advance.

Of course, in addition to these two seawater desalination technologies, there is also a frozen seawater desalination treatment technology, which uses the three phases of seawater, even if the three phases of seawater vapor, liquid, and solid coexist and reach a special point of equilibrium. If the pressure or temperature deviates from the three-phase point, the equilibrium is disrupted and the three-phase will automatically tend to one or two phases.

Vacuum freezing desalination is a low-cost desalination method that uses the three-phase principle of seawater, using water itself as a refrigerant, so that seawater evaporates and freezes at the same time, and ice crystals are separated and washed to obtain desalinated water.

Compared with distillation method and membrane desalination method, frozen seawater desalination method has low energy consumption, light corrosion and scaling, simple pretreatment, small equipment investment, and can treat seawater with high salt content, which is an ideal seawater desalination method.

However, both the freezing method and the distillation method have disadvantages that are difficult to overcome, among which the distillation method will consume a lot of energy and produce a large amount of pot scale in the instrument, while the fresh water obtained is not much; The freezing method also consumes a lot of energy, but the resulting fresh water tastes bad and is difficult to use.

After listening to Mo Qingming's chatter, Liao Bin finally understood some knowledge of seawater desalination, thought about it and said: "How can you say it, you have invented a special material, and you are going to use the membrane method to desalinate seawater, right?" ”

Mo Qingming smiled and said, "Clever! I'm researching materials, so naturally I start from the materials, but you're not entirely right, this time I brought the latest research desalination film materials here! ”

"I don't understand your technology, how can this film desalinate seawater?" When it comes to technology, Liao Bin is confused.

"Membrane separation technology refers to the technology of selective separation of mixtures of molecules of different particle sizes at the molecular level when passing through the semi-permeable membrane, simply put, it is to separate the water molecules and sodium molecules in seawater, because the water molecules are smaller than the sodium molecules, so when the film is designed, it only needs to open the pore size only through the water molecules!" Mo Qingming patiently explained!

"How simple is it?" Liao Bin's eyes widened, it was hard to imagine that this seawater could be turned into fresh water as long as it passed through a simple film, so how could the world still be short of water!

"The principle is how simple, but this biomimetic material is very similar to the cell membrane of biology, before we have developed a new technology, its cost is still very high, and the yield is very low, can not be promoted, the price of seawater produced is too expensive, can only use the second-level reverse osmosis method, through reverse osmosis to desalinate seawater. Now, you can get fresh water by simply pressurizing the seawater through a new material film! Mo Qingming smiled proudly.

Within the company, especially on the side of the research institute, the competition between each other is still very fierce, everyone doesn't care about material things, but they take the internal honor very seriously, after the material company accepted from Mo Qingming, it is inferior to other research departments, but he Mo Qingming has always been in a high position as a director, and he needs to come up with achievements that can subdue others.

This time, the bionic filter membrane led by Mo Qingming can realize the rapid, simple and low-cost desalination of seawater, which can be said to be a promising technology!

There are so many countries and regions in the world that are short of water! Not to mention other countries and regions, the Beijing-Tianjin-Tangzhou region, North China, and the northwest inland region in the north of the country are all very short of water, which seriously hinders the development of all aspects of society, but if there is this kind of cheap and simple new materials, there will be an inexhaustible supply of water, and you can use it as you want!
