ps: I have a reference to the description of the power generation, please do not sit down with the number of the party, if there is anything wrong, welcome to remind.

Yang Ruo was wearing protective clothing, and when she was sealing the iron pipe, she almost held her breath, and after she finished doing this, she quickly left, taking a big breath of fresh air.

It's terrible to have no common sense.

On the whole, the biogas digester made by Wang Fuzi is still doing well. The only drawback is that the sealing is not done well. But it was this only deficiency that became the fatal wound.

Because biogas is doped with oxygen, it is very dangerous. Not only is it easy to cause gas explosion. Moreover, with impurities, biogas is not easy to burn, and it is even less difficult to generate electricity.

Therefore, the principle of this biogas digester seems simple, but it is not simple. One is not good, and a major danger will occur.

These safety factor issues are more complicated, and Yang Ruo didn't have time to tell Wang Fuzi that he didn't want this old man to put himself in danger.

Fortunately, she arrived in time, otherwise if the old man had a whim and used fire to light the methane, maybe he would not only have lost his life, but the house here would have been blown away.

Yang Ruoke has become a sinner through the ages.

There are no plastic pipes here, so they can only seal the pipes by connecting the bamboo joints or making hollow iron pipes.

Hollow iron pipes should be of uniform thickness and large enough space. A fine pipe like this would not be made by an ordinary blacksmith shop.

However, Wang Fuzi didn't know what to do, which Yang Ruo was very satisfied with.

After removing the armor, Yang Ruo popularized the basic knowledge of biogas with Wang Fuzi and Shen Mu.

After listening to Yang Ruo's introduction, Wang Fuzi was also afraid for a while.

"So, I did something bad with good intentions?"

Yang Ruo said with a smile: "You actually did a good job, but the sealing is not good, and the biogas digester we are going to make now only needs to be several times larger than yours." ”

Hearing Yang Ruo's affirmation, Master Wang had a smile on his face again. "The old man knows, we'll do this later, just to seal those pipes to death, right?"

"Yes, the biogas produced is the purest and we can use it to generate electricity."

Then Yang Ruo checked the power generation equipment, and the carbon rod he needed was available.

Everything is very complete, and I have all the carbon rods I need, conductive saline solutions, and wooden boards. Conductive ropes, which are used as positive and negative electrodes, are wound around thin iron rods.

The 20-square-meter biogas digester has also been dug up, and you just need to throw something into it that can produce biogas, and then you can do it.

Of course, the specific operation of these things does not need Yang Ruo to do, she only needs to tell Wang Fuzi and Shen Mu how they work, and she must be able to do it with their ingenuity.

"Now I'm going to teach you how to apply chemistry to generate electricity. If in the future, we can use the power of the wind, as well as the heat of the sun, to generate electricity. Then when we cook in the future, or even read at night, we don't need to use oil lamps, but electric lights, and these electricity can be used continuously. ”

Yang Ruo's great idea made Wang Fuzi excited, even Shen Mu, who had always been weak, had a trace of longing in his heart, and he didn't know what the electricity Yang Ruo was talking about.

According to Yang Ruo's request, Shen Mu found a white porcelain bottle made of glass, which was used to make a light bulb, and the size was just right.

And there is an iron box made of pure iron in the material, which can be used to conduct electricity. The tin box is poured with a pre-prepared solution of highly concentrated saline, and then a large amount of wood paper scraps are mixed into the solution.

After doing this, choose a wooden board about the size of a tin box, and drill a small hole in the middle, which is used to put the carbon rod.

Then, according to the principle of power generation, Yang Ruo tied the positive and negative electrodes of the iron rod to the left and right ends of the carbon rod respectively, and then inserted the two iron rods into the highly concentrated salt water respectively, but the carbon rod would not directly touch the bottom of the box.

In this way, the iron box is the negative electrode, the brine solution is the electrolyte, and the conductive function of the carbon rod is done.

When Yang Ruo wore gloves and put the carbon rod and conductive iron wire into the water, the white porcelain bottle really lit up with a porcelain white light.

According to the proportion of brine concentration that Yang Ruo is equipped with, the power generation generated this time is estimated to provide a day's electricity.

"Ah Ruo, this is the electric light in your mouth?"

"Yes, this is the electric light, and the heat it produces is also very hot, so you can't get close to the bulb when you have your hands. And this kind of bright light will shine farther, not afraid of wind and rain. ”

In fact, the biggest difficulty now is that there is no copper wire here. If there is a copper wire, as a wire, it is a matter of minutes and seconds to electrify the entire Castle Peak Academy.

Yang Ruo didn't know how far the industrial level of Chengguo had developed at this time, and if the problem of wires could be solved, the problem would be solved.

Wang Fuzi and Shen Mu looked at the so-called electric light for a while, and when they saw such a small thing, the light emitted could illuminate the entire room as if it were daytime, and their mouths were also amazed.

"Girl, if our big biogas digester is successfully established, will it be more powerful than this power generation to generate electricity with these biogas digesters?"

"Of course, if only you had this wire here. I can get the entire Castle Peak Academy to be equipped with electric lights. After finishing speaking, Yang Ruo immediately picked up the charcoal pen in his hand and drew a diagram of the wire on the paper, which is best made of copper, so that it is easier to conduct electricity.

Then the copper wires should be wrapped in plastic to prevent them from being exposed, so that when people touch them, they are not easy to conduct electricity.

Taking the wire plan drawn by Yang Ruo's hand, Shen Mu hurriedly said: "I know a mine owner, if it doesn't work, I'll go to him and ask if this kind of copper wire can be refined." ”

When Yang Ruo heard this, his eyes couldn't help but light up, "If this kind of copper can be extracted and then made into copper wire, our Qingshan Academy will have benefits." By then, we'll have a lot of wires here, and the whole college will be electrified. ”

Shen Mu then asked Yang Ruo a few more details, and it was not until she understood all the principles of this power generation that she carefully put away the wire drawing.

The three of them have been studying the principle of power generation there for most of the day.

When it was almost time to eat at noon, Aunt Yun came, and after seeing Yang Ruo, they spoke politely.

Aunt Yun was also surprised by Yang Ruo's call.

Shen Mu then left, leaving Yang Ruo to learn to cook with Master Wang.

Today, Master Wang brought Yang Ruo to his kitchen in a serious manner.

Last time, he didn't use the kitchen much, and the place he went today is where he usually cooks.

After entering the house, there was a huge warehouse, which contained all the ingredients. Yang Ruo even saw that there was a small ice storage here.

These are used to make frozen ingredients, after all, Wang Fuzi is from the imperial chef in Kyoto, you know, the dishes they usually cook are for the emperor to eat.

In case something goes wrong, it's the head falling to the ground.

Therefore, they pay attention to cooking, which is to make every perfect and bring out the taste of each food to the extreme.
