Chapter 241: Plotting against her

At that time, Lin Wanxia was drowsy again because of him, and she said vaguely, "I don't mind."

The words were said casually, and she didn't think about it at all.

So when she saw the crowd of people in the canteen the next afternoon, Lin Wanxia was surprised.

There were people in the canteen and outside.

Most of them had short flat heads.

Lin Wanxia took a long time to find her voice: "You don't have to... go to work?"

After becoming a military wife, I realized that the life of officers and soldiers is similar to that of working to some extent, but they are not as free as social animals, and are a little more demanding than 996.

Their daily routine starts at five or five thirty in the morning and ends at nine in the evening.

This whole day includes drills, training, work, and study.

To be precise, it is very similar to high school students.

But most of the classes they take are "physical education".

Occasionally, there are cultural classes.

It seems that they also have "cultural" classes on Tuesday afternoons and Fridays.

I vaguely heard that it seems to be an ideological and political education class and a theory class.

So each class lasts for a whole morning or afternoon.

I don't know what the theory class talks about.

The baby-faced man also squeezed in, "Sister-in-law, we heard that you are opening a class, so we came here! Don't worry, it won't interfere with business. If you don't mind, you can teach us as well?"

Lin Wanxia: "..."

She looked at the green and dark overhead, and said sadly: "But, my temple is really small, can't accommodate so many people?"

"This is easy." The baby-faced man said, "Jiang Ying has told you that if you agree to teach us, we will go to the classroom for class. The tents are ready for you."

Lin Wanxia looked outside along the baby-faced man's finger.

Only then did she find that there was a new tent between the family area and the camp area.

Lin Wanxia: "..."

What a couple!

They calculated her clearly.

What else could Lin Wanxia say? She followed everyone to the new classroom.

In order to make it convenient for the officers and soldiers who came to buy things, Lin Wanxia left the door open and posted a large piece of paper on the door before leaving. There

were a few words written on it, meaning that if you need something, you can pay or put the money yourself.

When Lin Wanxia posted the paper, she thought that the quality of the officers and soldiers must be impeccable, and she was not afraid that everyone would not give money.

The problem is, if it is okay to help yourself, why should she bother to teach everyone?

Thinking about it, Lin Wanxia still became a teacher seriously.

Because there are more "students", she has more things to talk about. In addition to basic literacy and arithmetic, she also taught some other things.

For example, geography and history are mixed with the common sense of fishermen taught by her grandpa.

These military wives don't like to listen, but the officers and soldiers like it.

In addition, their schedules were different, so they were divided into two classes.

Lin Wanxia taught two classes a day.

In the morning, she taught the sisters-in-law. In addition to Chinese and mathematics, she also taught them some modern women's consciousness.

In the evening, she taught the officers and soldiers, and taught more and more.

Then she had more and more students.

Later, Jiang Sinian simply stopped the evening classes, and everyone came to follow Lin Wanxia for evening self-study.

"Isn't this not good?" Lin Wanxia asked.

"What's wrong with learning knowledge?" Jiang Sinian asked back.

Lin Wanxia: "..."

The point is, is she a bad teacher?

Jiang Sinian encouraged her: "Be more confident, you are better than my teachers! The instructor said that he would bring the instructors to learn from you."

Lin Wanxia: "..."

***

It was already the end of June when the class schedule got on track and formed a habit.

When Lin Wanxia was not in class, besides looking after the canteen, she was assembling solar energy and windmills.

Assembling these was easy, but the difficult part was how to collect the electricity converted from solar energy into batteries, and then convert the collected electricity into daily electricity.

The people that Chen Manshu had found had not figured it out yet, they just found the parts that were needed.

For those that could not be found, some substitutes were made.

The batteries used were the most basic lead-acid batteries.

Batteries can directly convert chemical energy into batteries, and the first generation of batteries were lead-acid batteries.

Later, when technology developed, lithium batteries and the like appeared.

Lead-acid batteries have been enduring because of their high cost-effectiveness and simplicity.

They are lead dioxide plus dilute sulfuric acid. Of course, there are requirements for the density of dilute sulfuric acid.

When the battery is discharged, the metallic lead acts as the negative electrode, an oxidation reaction occurs, and lead sulfate is generated. The lead dioxide substrate acts as the positive electrode, and a reduction reaction occurs to generate lead sulfate.

When the battery is charged, the two electrodes regenerate metallic lead and lead dioxide.

It is a repeated charge and discharge.

The so-called storage battery generally refers to a battery pack. The voltage of a single cell is only 2v. The voltage in an everyday electric car is 6v, and the batteries in electric cars are also groups of batteries connected in series.

Lin Wanxia understands the theory. After all, there are storage batteries on docks now.

But theory is often different from practice.

Lin Wanxia struggled for several days but still found some flaws.

After understanding the theory of solar and wind power generation, Jiang Sinian fiddled with all these things for a long time and finally succeeded.

Lin Wanxia: "..."

She looked at Jiang Sinian with jealousy.

Talent is something that is purely a gift from God.

After the windmill was placed under the tent, the wires were connected to the room.

It happened that the wind was strong in winter and there was no shelter on the sea. The windmill kept running and the electricity in the tent kept running.

On the twenty-third day of the twelfth lunar month, the Little New Year, the first electric light was turned on in Xiangyang Island at night.

For Lin Wanxia, ​​there are so many things that can be done with electricity.

The first thing is to make heating.

The charcoal stove is still not convenient enough. It will make the room very dirty, and you have to worry about the children bumping into things and getting burned, and you have to add charcoal at a fixed time.

Once you forget, the temperature in the room will drop rapidly.

Lin Wanxia installed the earth heater when it first arrived on the island. The reason why she laid a layer of tatami-like wooden boards in the tent was to install the circulating water pipes underneath. I

wanted to use the stove before, but the pressure was not enough to achieve hot water circulation, so I had to give up.

Now we use electricity, install a small motor, put a basin of water in the corner, throw a hot pot in, and the hot water circulates. The room is warmer than before when the stove was lit.

Of course, the hot pot consumes too much electricity, so it can only be used at night. During the day, the stove is still used to heat water.
