A month later, early in the morning, by the waterfall.

Han Tianyun looked at the generator that had been improved countless times, and his expression was very excited.

Since hunting the rhinoceros with Xiaohua that day, their food crisis has finally passed.

That's right, Xiaohua is the primitive little girl.

Because the meadow at the end of the stone field was full of small yellow flowers that looked like a half-moon, he gave the little girl a random name for the little flower.

As an earthling, this kind of irresponsible naming is shameful.

But in this inexplicable world, Han Tianyun's mind was not on the matter of choosing a name, he had more important things to do.

For example, build a generator.

For a month, the thunderstorm never returned, and the beast tide seemed to have disappeared.

He didn't know if it was good or bad, but even with the help of Xiaohua, the dangerous forest still couldn't go deep into too many areas, let alone find a way to get out of it.

That's why he put the manufacture of generators on the most important agenda.

Based on the memories of his previous life, these days, he has made many small tools, such as drilling wood to make a fire like the Australian brother, burning a fire not far from the entrance of the cave, and roasting the rhinoceros meat that he carried back into jerky, which was stored in Xiaohua and their own tree holes.

Another example is the sharp edges and corners of animal horns, which are used to cut extremely hard rhinoceros skins and snake skins, and make several highly defensive animal skin clothing.

What's more, he used those extremely flexible snakeskins as the insulation material for wrapping copper wires.

It can be said that he did all this both to survive and to make generators better.

Because hunting in the forest is just a way to keep them alive.

He is not like Xiaohua who can absorb the black fog in the forest to strengthen himself, and if he wants to change, he has to think of another way.

Building a generator is all he can think of at the moment.

Originally, this idea was born because I wanted to use electrical energy to resist the beast tide, but since the beast tide is gone, it doesn't matter whether it generates electricity or not.

But in the past month, Han Tianyun has another bold guess in his heart.

Since people in this world can use thunder and lightning to stimulate their bodies and then embark on the path of cultivation, wouldn't the electricity emitted by generators be more stable and safer?

You must know how violent and terrible the thunder and lightning quenching body that the nurse has been asking him to go to the cold pool to accept.

And now that there is no thunderstorm, there is naturally no chance of thunder and lightning quenching.

These days, as Xiaohua enters the forest to hunt, Han Tianyun is more and more shocked by her powerful strength.

When he hunted the rhinoceros, he seized the opportunity to stab the rhinoceros chrysanthemum, which was regarded as a blind cat touching a dead mouse, but since then, Xiaohua has learned to use the horns of beasts, and all opportunities to hunt wild beasts have been lost to him.

A fourteen-year-old boy, plus his age before the crossing, is probably an uncle in his forties, and eating a little girl's soft rice is not a shameful thing.

All this aroused the obsession in his heart to embark on the path of cultivation.

So, he decided to build a generator.

If lightning can bring out the potential of people, then the electric current from the generator should have the same effect.

Even if it doesn't work, you have to try to be willing.

"Well, line. Xiaohua, who was dressed in snakeskin, kneaded two copper wires and handed them over with copper wires wrapped in snake skin, with some curiosity in her eyes.

These days, Xiaohua can already speak some simple monosyllabic words, and the progress of the language is very rapid, and I believe that it will not be long before she can communicate normally.

Of course, all of this is because of my own intentional teaching.

After all, he has been a human being for two lives, and it is not very difficult to guide a primitive person who has eliminated hostility.

Before she met herself and the nurse, Xiaohua's life was like a blank slate, except that she could imitate the roars of various beasts, and was no different from ordinary beasts.

But since the success of that hunt, Xiaohua's sense of identification with them has grown rapidly, and when he sees him drill wood to make fire and roast fragrant and delicious cooked meat, his eyes turn to admiration and awe.

Not to mention that he also made a well-fitting and beautiful snakeskin coat for Xiaohua, which made her look at her with an indescribable complexity.

This kind of gaze, Han Tianyun still enjoys it very much.

Therefore, he is particularly concerned about Xiaohua's learning of languages, and tries his best to make her re-understand the things around her.

After all, in this world of only three people, Xiaohua's strength is one of the important guarantees for their survival.

Thinking of this, Han Tianyun grinned, took the copper wire from her hand and connected it to the wire left by the generator, slowly lifted the generator bearing, and moved it to a position where the waterfall water could impact the blades of the water wheel.

Then, he quickly lifted the boulder that he had prepared on the side and pressed the bearing on the rocky ground next to the waterfall.

Xiaohua also had experience, moved another boulder, quickly pressed on the other end of the bearing, and completely fixed the bearing of the turbine.

In order to fix the bearing, Han Tianyun thought of a lot of ways, and finally used the beast horn to grind out two small holes of suitable size on these two stones, which basically solved the problem.

Then he brought in a few more rocks and completely compacted the boulders on both sides.

"Come on! Now is the time to witness the miracle. Han Tianyun tore open the bark rope that held the blades of the water turbine and shouted excitedly.

Xiaohua stared at the changes in the turbine with wide eyes, and her expression was very focused.

......

According to the experience of the previous life, the principle of the hydrogenerator is actually very simple, but it is just cutting the magnetic inductance line to generate electricity.

But in fact, it is so difficult to make a hydro generator with bare hands, and just thinking about it can be daunting.

If it weren't for the thunder wedges of the permanent magnet and the high-purity red copper left by the poisonous spiders, it would be a fool's dream and impossible.

Not to mention that due to the limitations of the tools, the water wheel produced cannot withstand the impact of the turbulent waterfall at all, and even if the water wheel can rotate normally, how to stabilize the thunder wedge on the rotor has become a problem.

Even if the problem of magnet fixing is solved, what material should be used to make the stator, how should the copper wire be wound, what insulation should be taken between turns, and how to avoid short circuits and other problems will follow.

Taking 10,000 steps back, even if the turbine is running normally, it will eventually emit electricity, but what material can be used to completely fix the motor and ensure that the bearing does not shake indiscriminately is also a problem that cannot be bypassed.

As for the concepts of stator windings, electric potential, and magnetic potential, Han Tianyun has never heard of it at all.

Not to mention how to determine the rated current, power, and voltage according to the number of turns of the coil, he must not understand the technical issues.

A scumbag who can only score about 30 points in junior high school physics exams, wants to build a hydrogenerator in a different world where he doesn't even have Du Niang, and I'm afraid that people will laugh out of his big teeth when he says it.

But as the so-called ignorant are fearless, Han Tianyun thinks that building a generator is very simple, and he has several successful precedents in his junior high school experimental class.

This obsession made Han Tianyun recognize it, and he would definitely succeed.

Originally, Han Tianyun was not a person who gave up easily, and it could even be said that he was a tendon who hit the south wall and didn't look back, otherwise he wouldn't have hit the street every year for a dream, and he would have started over again every year, and finally died suddenly in front of the computer due to overwork, and crossed over to this other world.

Anyway, his purpose is only to emit current, as for how much power and how much voltage of current, it is not a matter of much importance.

Then let's start experimenting!

The first experiment ended with the scattered splashing of the turbine blades, and the second blade was strong, but because the bearing was not fixed and the shaking was too large, it finally fell apart completely......

In this month, he has failed more than 20 times, and even nearly 100 catties of copper wire have burned half of it.

How else to say that failure is success well?

With the accumulation of more than 20 experiences, Han Tianyun polished and improved again and again, and just today, he rearranged the number of turns of the copper coil again, feeling that he was very close to success.

Finally, with the rapid rotation of the water wheel, the bearing rotated at a constant speed, and there was no violent shaking, and at the same time, there was a constant buzzing sound between the coils, and everything was developing in a good direction.

The cold sky clouds did not dare to come out, and their eyes widened to observe the operation of the water turbine.

Five minutes later, the generator was still functioning normally, and the snakeskin copper wire in the distance erupted in strings of sparks among the weeds beside the path.

"It's done! Han Tianyun was overjoyed, and rushed towards the copper wire with an arrow step.

The next moment, he did not hesitate to put two copper wires on his hands.

In this primitive world, where is it possible to make light bulbs or multimeters and other current testing instruments, the best and most direct way to perceive the current is to use the body.

Anyway, lightning can't kill you, and you're afraid that the tiny current emitted by this generator won't be successful?

Zizi ......

The hairs on Han Tianyun's arms stood up, and a scorching smell quickly spread down his arms to his body, and soon, even the hair on the top of his head stood on end.

"Haha!"

Han Tianyun couldn't help but let out a hearty laugh, he was all too familiar with the feeling of this kind of electric current swimming on his body.

After a month of hard work, the electricity was finally sent out by him!

In this life, people really have to come up with a few bold ideas and immature suggestions from time to time, what if they come true one day?

Of course, there are still too many conveniences in this strange world, for example, on the cliff to the west, there is a rushing waterfall, which provides an excellent water energy resource for power generation.

For example, the trunk of the demon tree that was cut off by lightning is smooth and strong, and after polishing, it is a good material for making brackets and water turbine blades.

Another example is the snakeskin of the python, which cannot be pierced with the horns of the beast, and is very flexible and insulating, which is an excellent material for fixing magnets, brackets, turbine blades, and even wrapping copper wires.

What's more, the long horns left by those fierce beasts are as good as pig iron, all of which have good magnetic conductivity, which has become a ready-made material for him to make rotors.

As for the stator used to wind the copper wire, he found a section of the trunk of a bucket, and with the help of the nurse, it took half a month to hollow out little by little with a horn knife and grind out a hollow cylinder with a diameter of more than 30 centimeters.

Ten minutes passed, and Han Tianyun felt the continuous flow of electricity from his body, while observing the generator that was still running normally, and his heart was both excited and apprehensive.

At this moment, Xiaohua, who was standing on the sidelines and watching, suddenly let out a whining and screaming, and a hungry tiger pounced on him like a hungry tiger.
