Chapter 108: Instantly ranked second in the country

(I was not in a good state yesterday, so I posted an extra chapter, and also posted the wrong chapter. I didn’t post 108, but I clicked on the wrong chapter and posted 109. Didn’t everyone notice it?)

Weibo and Douyin are full of announcements of various cities completing the construction of public wireless power.

Some netizens even summarized these announcements and posted a video, which instantly became popular.

Many netizens also posted videos of using wireless power, and some big Vs and self-media also followed suit to release explanations of the impact of wireless power use on the future.

The recent traffic code is wireless power transmission, and the news in the entertainment industry has been suppressed. The hot searches of those stars are not seen in the top ten or even the top twenty.

However, during this period, a star grasped the key point and also posted a video of his test use of wireless power, which directly ranked first in the hot search.

But he was scolded by the general public again, saying that he only knows how to use traffic.

In the end, he was forced to close the comment area, and then instantly dropped out of the hot search list.

Everyone is speculating whether he couldn’t stand being scolded and spent money to withdraw the hot search.

This frightened some other stars who wanted to take advantage of the popularity, and they immediately deleted the information they were about to send.

As time went by, public wireless power was covered throughout the country, and almost everyone upgraded the Worry-Free Power APP and completed the registration.

The Worry-Free Power APP directly broke through 900 million, reaching more than 954 million users,

and directly ranked second in the domestic APP user list, second only to the 1.009 billion Fetion users.

The growth of Worry-Free Power users is simply unreasonable, which makes all companies dumbfounded. While they were racking their brains to think about marketing plans and find some customers, Worry-Free Power did it easily.

And they only paid 1 yuan to get a user.

For them, it is good to find a valid user for 50 yuan.

Fortunately, the server ordered from Huaban has been put into use long ago, otherwise this wave of relying on their original server would have been paralyzed long ago.

This is that the Yidian server is only used to store user information and verify device information, and does not provide other services.

The transaction information of the electronic RMB is only a transfer, and all services are provided by the state.

The electronic RMB, which was originally slow to promote, has suddenly increased by 954 million users and has been directly popularized throughout the country.

Then the government began to communicate with major network platforms to increase the payment channels of electronic RMB.

At night, on the rooftop of the large flat.

Liu Sen lay on the recliner, blowing the night breeze and resting.

"Brother Sen, we just talked about a cooperation today." Liu Ying and Yin Dan sat on the side and said to Liu Sen.

"Well, you can make your own decisions." Liu Sen said with his eyes closed.

Now all the company's affairs are basically decided by the two of them, unless it is a big deal or involves the laboratory, it needs to be reported to Liu Sen.

"Brother Sen, we think we still need to tell you about this matter, because this is a new field." Liu Ying said.

Listening to them say this, Liu Sen also cheered up and opened his eyes to look at them.

Seeing that Liu Sen was ready, Yin Dan said, "The company seeking cooperation this time is a medical device company. They want to produce a pacemaker that can receive wireless power."

This pacemaker is equipped with unlimited power transmission, which is really good. There is basically no need to worry about replacing the battery because it is out of power. In this way, the device can be used for life without any problems.

And the leadless pacemaker can be made smaller, less traumatic to people, and the cost can be reduced a lot.

Liu Sen nodded to indicate that there was no problem, and then he thought that his job was in this industry.

He wanted to enter the medical instrument industry at the beginning, and at that time he wanted to use his ability to improve accuracy and detection speed.

It seems that now is the time to start this project, and his influence is already there.

And this is definitely an industry that benefits the country and the people.

Liu Sen asked Liu Ying, "Are there any unfinished buildings of Hengda near our park? Is there one that is going to be built into a hospital?"

Liu Ying thought for a while before saying, "It seems that there is. It has been there. The building has been built, but it is just an empty shell without water, electricity and decoration."

"I plan to build a general hospital and use it there. By the way, I will also study medical equipment."

Most domestic medical companies rely on foreign imports, especially high-end equipment. 70% of the equipment in the country is imported from abroad, and the rest are basically low-end equipment.

In 2021, the total amount of imported medical equipment in China was 15.57132 billion US dollars. I believe that many people did not expect this data, and this data is still increasing at a rate of about 15-25% every year.

You must know that the national health expenditure in 2021 is only 1920.5 billion yuan. You can imagine how high the proportion of medical equipment is.

His entry into this industry can reduce the country's shortcomings and guarantee the medical care of all employees.

"You can communicate with the government, buy the place, and contact Jinling to cooperate with several large hospitals there to jointly complete the construction of the hospital. The current unfinished project will be used as the first phase, and all the places outside will be taken over for future expansion."

"Acquire a medical device manufacturer."

Both of them agreed, and then started chatting with Liu Sen. They drank Lingxin tea for a while, which can refresh the mind and eliminate fatigue, and then went into the swimming pool to play for a while.

The next day, the two of them arranged the opening of the hospital and the acquisition of the medical equipment company.

Liu Sen is still studying the electric propulsion engine.

In fact, when it comes to electric propulsion engines, many people don’t know that China’s space station uses electric propulsion engines, and it is the first space station in the world to use electric propulsion engines.

Although electric propulsion engines use electricity, they actually also need "fuel". Of course, this fuel is called propellant or propulsion medium, and it does not undergo chemical combustion.

The Chinese space station uses xenon. Xenon becomes plasma under the action of the electric field, and then ejects the engine to generate thrust under the action of the magnetic field and electric field.

Although xenon gas will not catch fire, xenon gas that becomes plasma can also emit light, just like fire, so electric propulsion engines also emit fire, of course not the flame after chemical combustion.

Electric propulsion engines have very high specific impulses and are particularly fuel-efficient. For the same work, they only need to carry one-tenth or even less of the fuel of chemical fuel engines.

So they are widely used in space.

After all, it is not easy to transport fuel to space. The rocket load is limited, and every bit of weight is carefully calculated when it is launched.

He has tried many working fluids, including hydrogen, xenon, and iodine.

It is found that iodine has many advantages. First, it has a higher specific impulse than hydrogen, and it is economical and easy to transport as a solid.

Of course, iodine also has many disadvantages.

Iodine is a solid and needs to be heated to become a gas, which makes the engine system much more complicated. Not only does the iodine need to be heated, but the entire delivery pipeline also needs to be heated, otherwise the iodine will easily stick to the pipeline, and if it accumulates too much, it will block the pipeline.

Iodine is corrosive. Whether it is metal or plastic, it will be corroded by iodine, so the space for storing iodine and the pipeline for transporting iodine vapor need to take anti-corrosion measures.

After iodine becomes plasma, its cations are more corrosive than xenon cations, and the inner wall and electrodes of the thruster are more susceptible to corrosion.

In other words, if iodine is used as propellant, the life of the engine will be shorter.

However, these shortcomings are not a problem. The new special glass material is directly used as the engine body, which can meet all requirements, is very easy to process, and has a very low cost.
