Regarding the design of dust removal equipment, the original idea was to build a thermostatic tank, through battery power supply to ensure that the water temperature inside is normal, once it needs to be used, after the water pump is pressurized, the ultrasonic oscillation principle is used to beat the water molecules into a fog, spread down from the top, and remove the suspended dust around them.

However, the idea is beautiful, the reality is cruel, after consulting a number of dust removal equipment, the answer is: no.

The reason is very simple, the accuracy of small civilian equipment can not meet the requirements of the vacuum environment - normal pumping tools need the cooperation of gaskets, that is, rubber, plastic and other parts, but the properties of these parts restrict the working environment of the overall equipment: below minus 50 degrees, can not work.

The processing capacity of the cryogenic area (below minus 100 degrees Celsius) required by Nie Peng is basically only available to super-large overall industrial equipment, such as industrial gas liquefaction technology, although the technical threshold is not high, but with the current energy structure of the lunar base, it is impossible to drive these big guys.

It is often hundreds of kilowatts of energy consumption, so where can Nie Peng find high-voltage electricity?

Well, let's use a watering can for the time being.

"Coal - steam engine, gasoline - internal combustion engine, TMD to the moon, except for solar energy, there is only nuclear fusion left. It's really embarrassing, I have to think of some other solution" Nie Peng muttered to himself while writing and drawing on paper, pondering how to solve the energy problem on the moon.

Ding dong. WeChat sound.

Pick it up and take a look, Jiaying sent it.

[How did you explain it to your mother?] 】

[Confession is lenient]

[Yo, you really have a girlfriend? What does it look like? 】

[Look in the mirror by yourself]

[Hey, what an old joke, my sister didn't agree]

[Hey, I'd better rent a girlfriend temporarily]

[Radical method? 】

[Hey, the first confession was rejected, so embarrassing]

[Good insincerity]

[Sincerity? Does it count if you invite you to eat]

Where are I waiting for you? 】

【。。。。 What about your festival? 】

[Don't talk nonsense, I'm hungry]

[Okay, Wanda Plaza, I just have something to discuss with you]

sent WeChat, immediately took the clothes in a hurry, and ran out of the door after saying a word to my mother, Nie's mother looked at the freshly cut vegetables, and her brows wrinkled:

"Don't say it early, I have to eat so many dishes until I can"

Wanda Plaza is very close to Jiaying's apartment, and when Nie Peng arrived by taxi, he had already seen her standing there waiting alone.

"Waiting a long time?" Nie Peng stepped forward, probably because of an impulsive confession in the morning, and it felt very unnatural at this time.

"It's okay, just arrived." Jia Ying naturally held Nie Peng's arm, as if she was not affected at all.

"Let's go, what to eat?" Throwing the problem at the other person is always a good way to solve the embarrassment.

"Eat roast duck! I just saw the photo on the big screen, my saliva was dripping, and I was hungry" Speaking of eating, Jiaying suddenly became interested.

"Hey, foodie." Nie Peng sighed.

"What words! This is called only food and beauty can not be disappointed! You are here for the beauty, I am here for the food, we complement each other" Jiaying's undisguised joy is very infectious.

"You can be said to be crazy when you eat, you shouldn't be a writer." Nie Peng praised.

"Where is it, Mr. Nie praised it, by the way, what are you going to tell me?" Jiaying asked.

"Ah, Silikang placed another 3 million orders. Just received it in the afternoon. Nie Peng returned.

"Euros?"

“RMB”

"3 million RMB?" Jiaying frowned, "Why is this purchase so little?" 0.6 grams? She took it for granted that the order trading varieties were intermediates, and thought to herself, how could she have set such a point at one time.

"It's not an intermediate, it's a rented tank. They rented 15 of them. Nie Peng explained.

"Fifteen? Do you know what's inside? ”

"I don't know yet, after the cultivation tank is ready, I will personally escort the car, after all, this thing is not good to pass through the hands of outsiders."

"Okay, if you buy a car tomorrow, you just have enough time to get a license plate. I can be your driver," Jiaying said on the side.

"Why are you so positive?" Nie Peng looked at Jiaying in surprise.

"Brother, can you not be active? If this rental is related to the clinical treatment of Sanin syndrome, do you know the value of this first-hand information? Jia Ying said as she drew a big circle in the air with her hands.

"That's enough to more than double your assets!" The look was as if he was in worship, and then he added, "No matter how much principal you have!" ”

"Ah, it sounds very good" Nie Peng thought along Jiaying's train of thought, finally able to reduce some pressure.

"Hey, you're waiting to make money, what are you going to do?" Jiaying looked at Nie Peng's stupid appearance and asked curiously.

"Well, I'm going to buy you a spacesuit, otherwise you can only move around ten meters by my side, how uncomfortable." Nie Peng said.

"Wow!! The first time I heard that a girl's spacesuit should be a lot more expensive than clothes, right? And what about the rest of the money? Jiaying didn't have the concept of the price of a spacesuit in her mind, and she thought that she would die for more than 100,000 yuan. So I wanted to ask Nie Peng how to use the money left after buying the spacesuit.

"The rest?" Nie Peng looked confused, "There's nothing left, the money may not be enough, where is the left?" "After calculating the price difference, there is still a difference of nearly 10 million, where is the left?

“。。。。 Eh, the spacesuit you are talking about, how much money is it? Jiaying seemed to understand something, and asked weakly.

"30 million" Nie Peng added, "It may not be possible to buy it yet, let's see if there is a channel when the time comes"

"You mean ... You're going to give me a piece of 30 million clothes??? Jiaying's mind was a little out of the corner. This gift is also a little too nondescript, right, it can't be worn out, and it can't be discounted, can it be photographed and sent to Moments?

"This is a must, the environment on the moon is so complicated, what if you don't prepare a spacesuit, what if you are in danger?" There is still a sentence that has not been said: you are the only one who can go to the moon with me at the moment, and I still count on your help when the time comes.

"Wearing 30 million clothes, I can only wear them on the moon, ah, why do I have a feeling of wanting to shout out, so depressed. What do you mean by that word? It is.. Dressed for a night out? Jiaying struggled to think.

"Brocade Night Walk"

"Yes, brocade night walk. Hey, let's not talk about this for now, how much money do you have in your account now, set aside for backup, don't move the rest in the near future, let's get ready to eat big fish. Jiaying thought of the big news that Ah Si Likang might break, and couldn't help but be moved.

"Well, I'll transfer 1 million to my mother, and there is still more than 6 million left, or I'll just hit your account and save trouble." Nie Peng said indifferently, as if he was talking about a business of a few hundred yuan.
