Chen Jin's design is quite good, and the feasibility is also very high.

However, he does not plan to promote the "life extension medical" technology immediately.

The technology of nutrition chambers for in vitro infant cultivation is still ethically controversial, and even difficult for many people to accept...... It may take thirty or fifty years for people to gradually accept it.

There is no resistance to life extension technology.

Five years.

Chen Jin considered waiting for five years later, the first Xinghai Hospital was built in the desert, and the life extension technology could be made public.

In addition, there is another thing that after the desert area contracted by Xinghai Technology reaches 500,000 square kilometers, the remaining desert will no longer be allowed to be contracted by Xinghai Technology, and no matter how much money there is, this is the upper limit of the land contracted by Xinghai Technology.

This was expected by Chen Jin, and he did not express any dissatisfaction.

"500,000 square kilometers is completely sufficient, and it is impossible to encompass all the deserts...... The above will not be allowed. ”

"But this is equivalent to the area of several provinces, and it will cost 50,000 to 10 trillion yuan to transform them all."

"In the future, most of the profits earned by Xinghai Technology in the domestic market will be invested in this desert...... It is estimated that it is barely enough. ”

Thinking of this, Chen Jin shook his head.

A few years ago, Xinghai Technology entered the desert, Aunt He Jia was very interested, saying that she had found the meaning of life and wanted to make some contributions to the cause of environmental protection.

Now the liquidity in the hands of my aunt should be more than 20 billion, right?

"The time is basically ripe, and those idle funds can almost absorb a wave."

However, these funds are not used in the deserts of the country.

It's the desert that is ten times as vast as abroad.

……

20X8, May.

Africa, Sahara Desert.

On the east coast of Morocco, there is a desalination research institute - Xinghai Desalination Research Institute.

On this day, Chen Jin made a video call and asked them about their recent research.

"Professor Bi, how is your research on nanomolecular permeable membranes? Does freshwater have advantages over other desalination methods in terms of production efficiency and cost? Chen Jin asked.

There are many ways to desalinate seawater:

There are common distillation methods. This is divided into high-temperature and low-temperature distillation, high-temperature distillation has high efficiency, and low-temperature distillation is more energy-saving.

There is a freezing method. Fresh water is separated from seawater by freezing at low temperatures.

There is the solar energy law. Solar distillation is a simple solar distiller consisting of a tank with a black porous felt core floating hole and a clear, closed-edged glass covering on top of the tank. Sunlight is projected through the transparent overlay onto the bottom of the black, adiabatic trough and converted into heat.

There is a multi-stage flash evaporation method. Flash evaporation refers to the phenomenon of rapid evaporation of part of seawater at a certain temperature under the condition of sudden decrease in pressure. Multi-stage flash seawater desalination is to evaporate heated seawater in multiple flash chambers with gradually decreasing pressure, and condense steam to obtain fresh water.

and molecular osmosis. This method is also commonly referred to as the "ultrafiltration method".

This method uses a semi-permeable membrane that only allows solvents to pass through and does not allow solutes to pass through 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 does not stop, this process is called osmosis. If an external pressure greater than the osmotic pressure of the seawater is applied to one side of the seawater, then the pure water in the seawater will reverse osmosis into the fresh water.

The biggest advantage of molecular osmosis is energy saving.

Among the above methods, Xinghai Technology focuses on the "molecular osmosis method".

For no other reason, one is the cost; The second is efficiency...... Other desalination methods have some shortcomings to a greater or lesser extent, but the molecular osmosis method can take both.

"It has reached the standard of large-scale application, Mr. Chen."

In the video, Professor Bi Yongfu said: "I have been working in this field for nearly 20 years, and now I see hope for the eradication of the 'desert' cancer of the earth. ”

"A set of large-scale desalination equipment, using the 'Bi Nano Permeable Membrane' produced by Shangxinghai Technology, 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. ”

"The construction of 100 sets of such desalination devices can solve the survival needs of 100 million people."

"If you build 1,000 of them, the entire Sahara Desert can be turned into a land full of life."

"The construction cost of each such desalination plant is about 1.5 billion, and the average electricity consumption per ton of water in the process of producing fresh water is about 1 kilowatt-hour."

"Assuming that the electricity cost is 3 cents per kilowatt-hour, and then the cost of pipeline construction, management and maintenance is included, the average desalination cost per ton of fresh water will not exceed 3 yuan per ton."

"It's a little more expensive than pumping fresh water from Lake Baikal, but it's not too expensive, and it's within the tolerance range."

"Mr. Chen, I suggest buying the desert here and developing it with the company's most advanced desert management technology, I believe that in just one or two decades, we will have a large oasis!"

"Xinghai Technology will become the world's largest land contracting company, and just those lands can bring huge benefits to the company."

Chen Jin nodded.

Fresh water is 3 yuan/ton, all costs are included, this cost performance is really okay, and it meets the standard of large-scale production.

During this time, Xinghai Technology also sent business representatives to conduct business negotiations with Morocco, Libya, Algeria, Niger and other North African countries, and purchased 1.5 million square kilometers of desert ...... The total expenses are about 150 billion (these are the profits obtained by Xinghai Technology in overseas business activities).

The contracts are signed in perpetuity.

Now the desalination technology is also mature.

Xinghai Technology can throw off its arms and do a big job in the Sahara Desert.

But the time is not quite ripe yet.

……

May 29th.

in the virtual world.

"Alice, what's the vote out? There's nothing wrong with being re-elected, right? ”

Chen Jin asked with his hands folded.

"With a vote rate of 82.17%, he won re-election without any suspense, and created the highest re-election support rate in history." Alice said.

"But I think the media scolds very fiercely, almost none of the mainstream media support Longfro, it is completely one-sided scolding, and there are also a lot of online polls, saying that the probability of Longfrew's re-election is no more than 1%......"

"Fake news masters, these are all false reports, but the final vote is true, and that's the only merit of this system."

Alice said again: "In addition, we have to add a batch of bodyguard robots to Longfro, and it is better to double the number of people." Since the beginning of this year, Longfro has been assassinated 187 times, an average of more than one per day, and I think this frequency will increase in the future, and the methods will be more intense and extreme, and we must be better prepared. ”

You must know that those whose interests have been damaged will never give up.

"I rub, 187 times?"

Chen Jin shook his head, this is just the beginning, and when the next action is launched, wouldn't the assassination frequency be even crazier?

It seems that except for the stand-in robot that can't die, under normal circumstances, God can't save country M.
