At the beginning of the civil castle, the Ming God of War was a little panicked

Chapter 395 The First Generator
What Tong Xuan is going to do is a hand generator, and the main equipment includes wooden supports, copper coils, magnets, glass lampshades and carbonized bamboo wire.

The bracket can be made by yourself, it is nothing more than a few wooden frames and nails.

There are ready-made magnets, just find one of the right size and use it.

Glass lampshades are cumbersome and need to be customized at a glass factory. Fortunately, the glass factory is also in Xishan, so there is no need to run around.

As for carbonized bamboo shreds, you need to cut the bamboo and burn it yourself.

Copper wire and cotton yarn are also readily available. So far, Zhu Jianshen has finally done a serious thing, which is to wrap all the copper wires with cotton yarn, and it is a thick layer, using more than a dozen rolls of cotton yarn.

Worried that he would make trouble when he was idle, Tong Xuan found another bundle of copper wire and dozens of rolls of cotton yarn for him to continue winding.

Zhu Jianshen was very interested at first, but later on, he gradually lost his patience, and just circled around in a hurry, perfunctory.

After three days like this, Zhu Jianshen, who had been wrapped in cotton yarn for three days, became more and more irritable.

"Master Tong, I've finished everything."

Tong Xuan took a look, the cotton yarns were thick and thin, messy, but he didn't care too much, after all, he was a child, so it was pretty good to be able to finish these.

Zhu Jian looked at him eagerly, as if saying, I'm just a child...

"Your Highness, please step back."

Tong Xuan was about to assemble it when he suddenly remembered the fire in the laboratory and hurriedly signaled Zhu Jianshen to keep a distance.

There are definitely risks in doing experiments. It doesn't matter if something happens to you. If you hurt the prince, the crime will be serious!
Zhu Jianshen was very obedient, took a few steps back, then found a small bench to sit down, and turned on the onlooker mode.

"Master Tong, what are you doing?"

"Master Tong, why does the copper wire need to be wrapped with cotton yarn?"

"That glass..."

"Your Highness!"

Tong Xuan felt irritable, so he had to interrupt: "Don't talk yet, I'll explain to you later, okay?"

"okay!"

Zhu Jianshen resisted the urge to do it, and watched Tong Xuan assemble the parts in front of him one by one.

Soon, a hand-cranked generator was assembled. Tong Xuan took a deep breath, held down the handle, and gently shook it twice.

However, nothing happened.

Tong Xuan frowned, and continued to shake. The wooden stick was slowly turned with the magnet, and he looked at the glass cover again. The carbonized bamboo wire inside did not respond at all.

Strange, why?

He couldn't understand it, because the drawings were given by the emperor. In his perception, the emperor is omnipotent, and it is absolutely impossible to be wrong.

Think about it, from improved firearms to steam engines, trains, ironclad ships...every invention can be called a miracle. How can a small generator go wrong?
There must be a problem somewhere!

Yes, I must have been negligent...

In desperation, the movements of his hands also became faster. Suddenly, he felt a flash of fire in front of him...

Tong Xuan took two steps back subconsciously, and then saw that the cotton yarn wrapped around the copper wire caught fire!

Zhu Jianshen jumped up from the bench excitedly, and shouted: "Yes, it was the same that day!"

After finishing speaking, he turned his head and ran away.

Tong Xuan came to his senses, looked around and saw that there was nothing to take advantage of, so he took off his coat, stepped forward and patted, and soon, the fire went out.

Zhu Jianshen had already run out of the door, but he didn't see Tong Xuan coming out, so he shouted: "Master Tong, come out quickly!"

However, he yelled twice, but he didn't see any movement inside. He thought something happened to Tong Xuan, so he boldly went back to the door and looked around.

"Hey, the fire is out?"

Tong Xuan didn't answer, just stared blankly at the natural generator just now, lost in thought.

Cotton yarn catches fire, what does it mean?
At least it can show that electricity has been generated in the copper wire!

He removed the copper wire, replaced it with a new one, and tried again.

This time, the filament flickered for a moment, and then the cotton yarn caught fire again.

Tong Xuan's eyes were full of hope. He probably understood one thing. The rotation of the magnet could indeed generate electricity in the copper wire. This point could ignite the filament or the cotton yarn.

Moreover, as long as the cotton yarn catches fire, the electricity is gone.

He hurriedly took out his pen and notebook and recorded his findings.

Then, continue to replace with a length of copper wire and experiment again.

Shockingly, this time, the carbonized bamboo wire in the glass cover continued to shine, and the cotton yarn outside the copper wire did not catch fire!
Tong Xuan was overjoyed, and kept shaking the magnet with his hand. After a while, finally, the bamboo thread flickered for a moment, and then went out.

He just stopped and found himself sweating profusely from exhaustion.

I want to take a pen and paper to record, but I can't even lift my arm.

Zhu Jian squatted beside him and asked, "Master Tong, that, that thing just now...is it a candle?"

"no!"

Tong Xuan shook his head with a gratified smile on his face.

"Is that...an oil lamp?"

"Not at all."

Tong Xuan closed his eyes and lay back, feeling relaxed all over.

It worked!
"Master Tong, don't lie on the ground, it's so cold..."

Before Zhu Jianshen finished speaking, Tong Xuan held him in his arms.

"Your Highness, we succeeded, succeeded!"

Tong Xuan was very excited, and at this moment, he didn't care about the dignity of the monarch and his ministers, just like a child, he hugged Zhu Jianshen and laughed loudly.

Zhu Jianshen rode on him and said, "Master Tong, what is that?"

"It's a generator!"

"What's a generator?"

"It is to generate electricity through a set of devices, which is the electricity of thunder and lightning in rainy days!"

"Lightning...isn't it from the Thunder God and the Lightning Mother?"

"Ha ha!"

Tong Xuan smiled, and said: "With the generator, there is no need for Thunder God and Lightning Mother!"

Zhu Jianshen turned his head, glanced at the so-called "generator", and asked, "What's the use of electricity?"

"There are too many uses!"

Tong Xuan closed his eyes, his face brimming with joy of success.

"The first one is the electric light!"

"Light...what is it?"

"It is a lamp that uses electricity. With electric lamps, there will be no need for oil lamps in the future."

Tong Xuan opened his eyes, hugged Zhu Jianshen and put it aside, then picked up a pen and paper and began to record.

He had to record the experimental results as soon as possible, and then look for the reasons for the failure of the previous experiments.

As for the last time, although it was successful, it was obvious that the filament was not resistant to burning and could not continue to emit light.

This alone requires a lot of energy to improve. Specifically, it is to find different varieties of bamboo from various places, use different methods in carbonization, and finally find a filament with good luminous effect and fire resistance.

However, what he couldn't understand was why in the previous experiment, the cotton yarn around the copper wire caught fire, but in the last experiment, the filament was burned, but the cotton yarn was intact.

Tong Xuan thought for a long time, but was still at a loss.

I'm afraid only the emperor can answer this question, but he doesn't want to bother the emperor with these trivial questions.

So, he removed the copper wire, held it in his hand, and looked at it carefully.

This copper wire was already the first time Zhu Jianshen had wound it, because the cotton yarn around it was very thick and tightly wrapped.

Suddenly, a thought flashed through his mind.

Could it be related to the tightness of the cotton yarn wrapping?

However, the cotton yarn outside the first two copper wires has been burnt clean. Thinking about it now, I don't remember what it looked like at that time.

"Your Highness, do you still remember that the copper wire that caught fire in the laboratory was wrapped with a lot of cotton yarn?"

After Zhu Jianshen listened, he tilted his head and thought for a while before saying, "Not much!"

Tong Xuan's eyes lit up, and he asked again: "Your Highness, remember clearly?"

"Ok!"

Zhu Jianshen nodded and said, "Those cotton yarns are not tightly wrapped, and a lot of copper wires are exposed, just like this!"

As he spoke, he pointed to the ground. The copper wire should be wrapped by him later, far less careful than the first one.

Tong Xuan picked up the thread and observed it carefully.

Soon, he found a clue.

All the copper wires have been made into cylinders, and this wire, due to the loose wrapping of the outer cotton yarn, leads to direct contact between the copper wires.

Look at the thread that was successfully tested just now, but it is tightly wrapped and has no contact at all.

By now, he seemed to understand.

"Your Highness, please stay away!"

Tong Xuan replaced the filament and then the copper wire that was in contact. When ready, he shook the handle. With the rapid rotation of the magnet, there was a sizzling sound, and a burst of electric sparks burst out from the copper wire. Immediately afterwards, the cotton yarn ignited again. .

Zhu Jianshen stayed far away and shouted: "Master Tong, it's on fire!"

Tong Xuan did not rush to put out the fire, but danced excitedly, as if he had found the door to the new world.
-
Supervisor of ceremonies, Wynn's heart is about to break.

As the chief eunuch of the Ouchi, the Forbidden City caught fire twice in a row. Isn't this a slap in the face?

Are those people from the Academy of Sciences studying how to set fire every day?

If it goes on like this, will people still be allowed to live?

This is the palace, if something goes wrong, who will be responsible?

He first found Belin, and the two of them accompanied the emperor on a trip to Nanyang. They were also comrades who had carried guns together. If you have something to say, there is no need to go around in circles, just be straightforward.

However, regarding this problem, Belin was also very helpless.

Because many projects of the Academy of Sciences require experiments to verify, and doing experiments will definitely be risky.

What he can do now is to strengthen preventive measures, and ask the students to pay attention to safety as much as possible during the experiment, so as not to cause accidents.

In desperation, Wynn had to do it himself and make great efforts to rectify it.

Inside and outside the imperial palace, the six ministries and nine ministers, the Imperial Academy, the Academy of Sciences, and all yamen must be thoroughly checked to see if there are flammable and explosive materials, whether there are fire prevention measures, and there are even emergency plans for how to deal with fires.

As for candles and oil lamps, they are strictly controlled.

Where candles are needed, an application must be made in advance, and they will be distributed strictly according to demand.

After dawn, if it is not used up, it must be turned in to the warehouse, and it will be reapplied after it is used at night.

For the Liubu Jiuqing and Hanlin Academy, the use of candles and oil lamps is not too large, because this is the outer city of the imperial palace, and they are only on duty during the day, and must leave the Meridian Gate at night before dark.

At most, it is cloudy and rainy, when the light is not good, or when it gets dark early in the winter night, you need to turn on the lamp.

Now the director of ceremonies strictly controls the lights and candles, so don't light them. If it gets dark early, just leave work early.

Or sit and drink tea, and get off work when it's time to drink.

On weekdays, if it is cloudy and rainy, just make do with it, do the work if you can, and drink tea if you can't.

However, the impact on the Academy of Sciences is greater.

Because many experiments in the Academy of Sciences required fire, oil lamps, candles, and even coal were indispensable.

And these things are all strictly controlled.

If you want, you can, hit the application.

If the application is approved, it will be distributed according to the amount, and there will be full supervision by the Dongchang's fan service, and the unused must be handed over in full.

But the problem is, this application process is troublesome.

After all, the Supervisor of Rituals is not engaged in scientific research. He doesn't know what project or experiment to do, so that during the review, he always chops up as he can. If he sees that you apply for ten catties of lamp oil, he will ask, one catty is enough not enough?

Not enough, what about the two catties?

not enough?
That two and a half catties, no more!

In short, it will never be issued in full.

In just a few days, the Academy of Sciences was full of complaints. Belin approached Wynn under great pressure, hoping that the Supervisor of Rituals could relax the restrictions on materials such as lamps and candles. Otherwise, the progress of many projects of the Academy of Sciences would be affected.

In particular, some key issues are at the critical point, and now they are stagnant, which will not only affect the progress, but also affect morale.

Wynn said with a half-smile: "Our family is also very difficult to do. The sky is dry and the things are dry. The Academy of Sciences needs so much candle oil every day. If the water runs out, who will be responsible?"

Belin replied: "The Academy of Sciences will handle it with caution."

Wynn smiled lightly and said: "Dean Bei, you and I both work for the emperor. We should be considerate of each other. There have been no major incidents in the Forbidden City for many years. Your Academy of Sciences conducts experiments every day... Sigh, our family is also very difficult do it!"

Belin explained: "Since it is science, of course it needs experiments to prove it, otherwise how to prove it?"

"Our family doesn't understand what you said, but we know that there must be no accidents in the Forbidden City, otherwise, our family has a hundred heads and it's not enough to chop off!"

"Eunuch Huai, there's no need to make such a big fuss, right?"

"This is really not a big deal!"

Wynn shook his head and said, "I don't need our family to say more about how the power laboratory gets water?"

"But, that's just... a special case..."

"Who can guarantee that other laboratories will not travel under special circumstances? This is the imperial palace, and the emperor's safety is always the first priority. Besides, the Six Departments, the Nine Ministers, and the Imperial Academy didn't say anything. Only the Academy of Sciences complained. Our family thinks , you, the dean, should take care of it."

Bellin was extremely annoyed, but there was nothing she could do.

Because he has no way to refute, or in other words, he also knows that there are indeed some hidden dangers in the laboratories under his control.

Now, your director of ceremonies directly cuts across the board, not even giving a candle or a catty of lamp oil. Isn't that too much?
If he encounters resistance in other areas, he will go directly to the emperor.

What's more, if you encounter someone who deliberately makes things difficult for you, you will be beaten up if you are in a hurry.

But not this time.

Wynn is right, this matter is really difficult.
