I picked up a planet

After putting this matter in order, Zhang Long saw Liu Jiahui’s eyes showing gratitude. She helped Lu Wei to go to the hospital.

It seems that Jiahui is someone who has a boyfriend! Zhang Long thought so silently in his heart, it was inevitable that he would feel a little embarrassed about this first love!

“If you need my help, just come to the Mastiff Dragon Company to find me!” , Zhang Long said this to Liu Jiahui, who was about to leave!

Liu Jiahui only turned her back to Zhang Long, and there were no other words to describe such an atmosphere.

Both of them know that the other party is no longer the same as themselves…

August.

A jeep drives on the edge of Africa’s vast Sahara Desert. A few Huaxia people walked down from the car.

Ni Kun is a college student who just graduated this year, because of his good 1o1 ranking, he was hired by the multinational Mastiff! Before the excitement passed, Ni Kun was sent to Africa!

Ni Kun wanted to cry without tears, so he had to complain in his heart about Zhang Long Cao Nima, who belonged to the exploration field team and was responsible for research and other matters.

Morocco, on the eastern coast, Mastiff has built a new ‘desalination research institute’ here to do desalination research.

There are many ways to desalination.

There are common distillation, freezing, solar energy, multi-stage flash evaporation, and molecular permeation.

However, he does not plan to promote the “cloning of humans” technology immediately.

Organ transplantation technology will not encounter much resistance, but the nutrition chamber technology and cloning technology for in vitro breeding babies are still ethically controversial, and even many people find it difficult to accept that it may take ten years to gradually accept.

Zhang Long thought that after a year, the first hospital was built in the desert and the organ transplant technology could be made public.

In addition, there is another thing, the area of desert contracted by Mastiff dragons.

This was expected by Zhang Long, and he did not express any dissatisfaction.

“500,000 square kilometers is completely enough, it is impossible to encircle all deserts, and the above will not allow it.” , Vice President Zhou Liang frowned.

“But this is equivalent to the area of several provinces, and it will cost 50,000 to 10 trillion yuan to transform it all.” , Financial Lin Ruoshi took the report and read.

“In the future, most of the profits earned by the mastiff dragon in the domestic market will be invested in this desert, which is estimated to be barely enough.” , Thinking of this, Zhang Long shook his head.

A few years ago, Mastiff entered the desert, and Ma Dongqiang was very interested in this, saying that he found the meaning of life and wanted to make some contribution to the cause of environmental protection. Now the liquidity in Ma Dongqiang’s hands should be more than 20 billion!

“The time is basically ripe, and those idle funds can almost absorb a wave.” , Zhang Long still wants Ali to join the group. Ali’s Ma Dongqiang was particularly interested in purifying trees before, and if he gave Ma Dongqiang the two technologies of purifying trees and seawater purification, he would definitely join the group to build a factory in Africa!

The above methods, the Mastiff focuses on the “molecular penetration method”

This method uses a semi-permeable membrane that only allows solvent permeability and no solute permeability to separate seawater from fresh water. Under normal circumstances, fresh water diffuses to the seawater side through a semi-permeable membrane, so that the liquid level on the seawater side gradually rises until a certain height is stopped, this process is infiltration. If an external pressure greater than the osmotic pressure of seawater is applied to the seawater side, the pure water in the seawater will reverse osmosis into the fresh water.

The biggest advantage of molecular permeation is energy saving.

This technique was picked up by Zhang Long from the ruins of Blue Star, and although Blue Star’s climate has changed drastically, there is no sea water now, but the feasibility of using this technology on Earth is very high.

There are no other reasons, one is cost; Rate…… Other desalination methods have more or less flaws, but molecular permeation can take care of both.

On this day, Zhang Long made a video call to inquire about the recent research status of the institute.

Zhang Long asked: “Professor Li, how is your nanomolecular permeable membrane research, and whether the production efficiency and cost of fresh water have achieved advantages over other desalination methods?”

“It has reached the standard of large-scale application.”

In the video, Professor Li Le said: “I have struggled in this field for nearly 20 years, and now I see hope to eliminate the cancer of the earth, ‘desert’. ”

“A set of large-scale desalination equipment, using the ‘Lee’s nano-permeable membrane’ produced by Shangmalong, can seep out 12 tons of fresh water per second, and produce more than 1 million tons of fresh water per day… Enough for a city of one million people. ”

“If 100 such desalination units are built, they can meet the survival needs of 100 million people.”

“If 1,000 are built, the entire Sahara Desert can be turned into a land full of life.”

“The construction cost of such desalination plants is about 1.5 billion yuan per building, and the average electricity consumption per ton of water in the process of producing fresh water is about 1 kWh.”

“Assuming that the electricity cost is 3 Mao one degree, and then the cost of pipeline construction, management and maintenance, the average desalination cost per ton of fresh water will not exceed 3 yuan / ton.”

“It’s a little more expensive than pumping fresh water from Lake Baikal directly, but it’s not too expensive, it’s within the affordability.”

“Mr. Zhang, I propose to buy the desert here and develop it with the company’s most advanced desert treatment technology, I believe that in just one or two decades, we will have a large area of oasis!”

“Mastiff will become the world’s largest land contracting company, and that land alone will bring huge benefits to the company.”

Zhang Long nodded.

Fresh water 3 yuan / ton, all costs are included, this cost performance is really possible, to meet the standard of large-scale production.

During this time, Mastiff also sent commercial representatives to conduct commercial negotiations with North African countries such as Morocco, Libya, Algeria, and Niger, and purchased 1.5 million square kilometers of desert… The total expenditure is about 150 billion yuan (these are the profits obtained by the Mastiff dragon from overseas operations).

All permanent contracts were signed, and now desalination technology is already available.

The mastiff dragon can shake off its arms and make a big fight in the Sahara.

But the time is not yet fully ripe.

In fact, desert environments are not as easy to manage as they think.

Especially in the large desert where the climate often changes abruptly, sometimes a sandstorm will make all efforts go to waste.

Even if there is plenty of fresh water, it is useless, the wind will blow off the newly planted trees for seconds, and the moving sand pile will flood the newly built house… It seems like a small amount of sand, but it can drown everything.

But the mastiff dragon is not helpless in this regard.

Especially in a very large desert like the Sahara, the Mastiff Dragon simulated a set of effective transformation schemes in a supercomputer.

This plan is called “dominating Africa.”

That is, using high-strength graphene materials, in the desert, build a semi-ellipsoidal transparent cover with a diameter of 1.5 kilometers and a maximum of 150 meters, called a “dome”

This large, transparent cover is very strong and has a smooth surface to withstand sandstorms above category 18.

In addition, considering that the sunlight in the desert area is abundant and strong, the surface of the transparent cover is also coated with a thin layer of solar power generation material, which generates enough electricity for tens of thousands of households.

A large, deep pond was dug inside the dome to hold fresh water pumped from the sea.

Plant some date palms around the pond, build some houses, warehouses and factories… Once the sandstorm came, enough people would take refuge including 100,000 people.

But the domed base is not for human habitation, but to facilitate the transformation of the desert.

After each dome is erected, the drone will evenly spray a special glue into the desert around the base, and the glue (Hao Zhao Zhao) will solidify the fine grains of sand together, thus losing mobility and cannot be swept away by the wind.

Immediately with the domed base as the core and a radius of 100 kilometers, each base is responsible for the transformation of 3.14 square kilometers of desert… About 300 bases can handle the entire Sahara Desert.

And with sufficient equipment and manpower, it will take about ten to fifteen years to complete the transformation.

But the more fatal drawback is that it is expensive.

The construction cost of a single dome base and supporting facilities exceeded 100 billion.

If you build three hundred, you need 30 trillion … And that’s just the construction cost.

If all the costs are added together, the transformation of the entire Sahara Desert is estimated at more than 100 trillion.

With the financial resources of the Mastiff Dragon, it is impossible to complete such a huge project… Zhang Long also did not consider paying so much money.

So what to do?

The only way to seek cooperation from other countries is to invite private capital to join and solve financial problems.

Ali’s Ma Dongqiang was particularly interested in purifying trees before, and if he gave Ma Dongqiang the two technologies of purifying trees and seawater purification, he would definitely join the group to build a factory in Africa! _
