"But what?"

Luo Feng hurriedly asked, speechless in his heart, is the robot talking intermittently?

"But among them, there is a technology called soaking liquid, this thing, I'm afraid it's not easy to produce! Because such a thing, even if you know how to make it, you can't produce it without the corresponding factory equipment! ”

"Is this thing hard to produce? What about looking for ready-made ones? Luo Feng asked.

"The amount needed is too much! Finding ready-made ones can only be used for a short time, and they can't last too long! Xiaomei said.

Luo Feng also felt a little scratching his ears and cheeks.

If you think about it, too.

This is a big project, transforming so much fresh water every year, if you don't produce soaking liquid, and you go to find a ready-made one, then even if all the source planets are found, it won't last long.

For example, there is indeed some toilet paper used by human beings on the market today, but if it is not produced and only used, this thing will be consumed too much, and the inventory will soon be used up.

Xiaomei said: "Except for this soaking liquid, the others are much simpler, as long as you find enough materials, Xiaomei can also get a desalination system!" ”

"So how much concentrated brine do you know and how much it pollutes the ocean?" Luo Feng asked again.

"There will be no concentrated brine, everything will be filtered at the atomic level! Water to water, minerals to minerals! ”

Xiaomei smiled and said again, "However, the seawater of some planets contains special materials, and it is difficult for the reverse osmosis method to take effect!" ”

"So I suggest that the master should use more high-tech means to do it, it will be better!"

Speaking of which, Xiaomei also stopped.

After all, it doesn't seem to be good to see the owner's face.

The way I know I've said the wrong thing and suddenly stops is really cute.

So, Xiaomei said obediently: "As for the reverse osmosis method, everything else is very easy, but the soaking liquid I just told the master is a big problem!" ”

"Okay, anyway, what my friend needs is a desalination plant that a pre-nuclear civilization can build! That's the point! As for the solution that can't be solved, I'll think of a way! ”

Luo Feng said slowly.

"Pre-nuclear civilization, huh?"

Suddenly, Xiaomei heard a key word.

"Yes! That's what I said just now! ”

"If the pre-nuclear civilization is relatively low, they will not infiltrate some substances that are difficult to separate into the seawater of the ocean, so the scientific and technological content of the immersion solution can be reduced!"

Luo Feng nodded, for advanced civilizations, a lot of substances will definitely be developed, and they will all seep into the sea when the time comes.

For example, nuclear wastewater.

It's like the ancient times of the earth, and they can't get this kind of nuclear waste water if they want to.

That should be the truth.

"Speaking of this soaking solution, how do you use it?" Luo Feng asked.

Seeing this, Xiaomei quickly went to the printer next to her and printed a list, "Master, according to this method, the filter membrane is manufactured, and the seawater will pass through the filter membrane to obtain preliminary fresh water." With the soaking solution, soaking for three days, pure fresh water can be obtained, and the minerals needed in the seawater can also be separated. Filter membrane devices generally do not break, and the amount required is also very large, but there is no problem in the production of filter membranes in pre-nuclear civilization. It is this immersion solution that only 10 million tons of seawater can be obtained from 1 ton of immersion solution. ”

When Luo Feng heard this, his face changed slightly, a ton of soaking liquid only solved 10 million tons of seawater?

Then 10 billion tons of water per year only need 1,000 tons of soaking solution.

This efficiency is also terrible.

However, the amount of soaking solution is also very large.

"Master, it can only be said that in the pre-nuclear era, there were relatively few harmful substances in the seawater! Otherwise, the scientific and technological content of the soaking solution should be increased, and the amount should also be increased! ”

Xiaomei's meaning is very clear, because it is a pre-nuclear civilization, the scientific and technological level of the soaking liquid can be reduced, and the dosage is also reduced.

"If it's just this amount, we look directly for ready-made ones, and it's easy to find 1,000 tons of immersion liquid! After all, there are so many factories, construction sites, and mines on the Tianyuan Planet! They all need to be treated with soaking solution to treat wastewater or seawater! ”

Xiaomei opened her mouth to say this.

Luo Feng's face gradually unfolded.

If you can use ready-made ones, then it's a good thing.

The amount needed is too large, and it is not easy to find a ready-made one, and it will be consumed quickly.

If it is consumed, then even if there is a desalination plant on the other side of the earth, it will be useless.

After all, 1 ton of immersion liquid, in the face of pre-nuclear civilization seawater, can be very effective, can solve the problem of 10 million tons of seawater.

However, in the face of seawater in the high-tech era, one ton of immersion liquid can only convert 10,000 tons of seawater.

In this case, it is equivalent to 1,000 times less dosage.

That's naturally much easier.

"Then Xiaomei, you can find me 1,000 tons first! This equivalent can meet the annual demand of 10 billion tons of fresh water! ”

Luo Feng smiled.

You don't have to look for 1 million tons, it's really beautiful!

Fortunately, it is a pre-nuclear civilization, and the quality of the sea water is relatively good.

Otherwise, Luo Feng really couldn't do anything about this matter.

"Also, Xiaomei, the production method of the filter membrane, you plan it for me as soon as possible!"

It's simple, but it's a must.

"Knowing the master, I will plan a design plan as soon as possible, covering an area of 30 square kilometers, desalination of 100 tons of fresh water per year, is that what it means?"

"Yes, my Xiaomei is smart, do you want to adjust the lover mode and spoil you!"

Luo Feng was happy in his heart, and naturally joked.

"Okay, okay!"

"Hahaha!"

Luo Feng smiled, such a shameful thing, forget it, even if this robot actually experiences it more comfortably than humans.

But Luo Feng felt that all things are born, and men and women originally wanted that.

If you directly find a machine instead.

It's a bit against the sky.

Lao Tzu said that the Tao is to go with the flow, and if you don't go with the flow, you will one day go to destruction.

For example, if this robot replaces a woman, perhaps humanity is facing a rapid population decline.

That's the price of not going with the flow.

I waited for about half an hour.

This more than 30 square kilometers of desalination design drawings were planned by Xiaomei, which is worthy of being a robot, and this work efficiency is equivalent to hundreds of designers on the other side of the earth.

Luo Feng looked at the design drawing.

It's all in Chinese.

But when he saw that the steel pipes and equipment needed were completely astronomical, Luo Feng was silent.

To do it privately.

Few people can afford the cost of these materials.

In fact, it is equivalent to the filtration membrane technology, which is only a very simple technology that can be produced on the earth, and the filtered soaking solution is placed in water for three days, which is the most critical step.

The soaking liquid can't be produced on the earth, so Luo Feng needs to look for it here.

"Nicely designed, magnificent factory!"

"Not bad, Xiaomei!"

"Still. Then print out this set of filter membrane technology for me, and I will show it to customers! ”

Luo Feng knew that if he wanted to do this, it was impossible for Huaxia to just listen to Luo Feng's casual words and build such a big factory.

You have to see the actual technology to solve it.

"Also, get me some soaking liquid! I saw you treating your wastewater at home not long ago, this is what you should use, right? ”

"Yes, master, there should be a few boxes at home!" Xiaomei said with a smile.

That's all that is said and done.

Luo Feng was taken by Xiaomei to see the soaking liquid, this thing is like some ordinary shampoo.

But a pile of wastewater, or seawater, slowly starts to clean up under the soaking of this thing.

Although Luo Feng can't wait three days to see the effect.

But the planet uses it to treat seawater and wastewater, so it's certainly fine.

Back in the dormitory of the Great Northwest Secret Airport on this side of the earth, it was already late at 11 o'clock.

Luo Feng was a little hungry.

Pulled up Qin Dingguo, who was about to go to sleep, and went to eat supper.

In the war department, there is definitely no supper, but a few people are hungry, but they can go to the canteen to open a small stove.

The food is also very simple, chicken thighs, noodles, eggs.

Don't think about it, there are other prawns, grilled fish or whatever.

In this place, it is very good to have chicken legs and eggs, think about those soldiers in ancient times, what they ate was porridge and drank the river water in the open air.

But they still go to be soldiers, they can't starve to death, right?

Of course, there is no wine.

Luo Feng also secretly asked Qin Dingguo, I heard that the king of soldiers is not the king of wine?

However, Qin Dingguo said that the pilots here did not drink alcohol during their duties.

Unless it's a holiday home, then you can drink whatever you want.

After all, such a thing as the Air Force is really a baby bump.
