Datang: At the beginning, I wanted to rebel against my father-in-law

Chapter 247 The benefits of light bulbs!
"Could it be that there is something wrong with lighting candles?" Li Chengqian and others couldn't understand again.

Using candles for lighting is something that people in the Tang Dynasty do almost every day. They really can't figure out what's wrong with using candles in steel mills.

Could it be that Su Feng disliked wasting it?

Changsun Wuji shook his head slowly, this time even he couldn't figure out what the connection was.

"During the steelmaking process, a lot of dust will gather in the air. I just looked at it, and the ventilation effect of the entire steelmaking plant is very limited!"

"If the dust in the air is dense enough, these candles are very likely to cause an explosion. Do you think there is any problem?" Su Feng's face was so gloomy that he looked at the crowd and said in a low voice.

This is more serious than the boiler room poisoning thing!

Fortunately, I discovered it early, and there was no problem before that, otherwise, if something happened, it would be a big problem that shocked the world.

By the time.

Not only him, but everyone present can't escape the responsibility!

Hearing Su Feng's explanation, Li Chengqian, Changsun Wuji, and Li Jing finally realized that Su Feng had talked about the same case in chemistry class.

The same situation will occur in the flour mill. In the case of dense dust, there must be no sparks, otherwise it will cause a large-scale explosion.

This contains a lot of chemical knowledge. To be honest, when Su Feng was talking about this issue, they didn't take it too seriously.

In their view, the chances of this kind of thing happening are very small. From ancient times to the present, it seems that they have never heard of similar problems.

But I didn't expect... There is such a hidden danger in this steel factory!

Now knowing the possible consequences, even Li Chengqian and the others broke out in a cold sweat from fright.

joke.

If an explosion occurs in the entire steelmaking plant, I am afraid that even the imperial palace will be affected. Not only will it cause serious consequences, but even the court may become a joke.

"Then...then what should we do next?" Li Jing, who had never had a chance to express his opinion, finally raised a question at this moment.

"The steelmaking plant has to keep running at all times. It may be able to sustain it during the day, but at night, it can't work without candle lighting!"

Following Li Jing's question, everyone's eyes also focused on Su Feng.

They also wondered how the steelworks would keep running if candles were not available.

I see.

Su Feng took out a light bulb from his pocket, and slowly displayed it in front of everyone.

Regarding light bulbs, Li Chengqian and Changsun Wuji and other limited people have already seen them when they were in the north, and they know that this thing is very magical.

but.

Changsun Wuji didn't understand very much, why did Su Feng take out the light bulb at this time?
When he saw the light bulb in the north, he specifically asked the other party that the use of the light bulb must be coordinated with electricity, which is the generator that His Majesty cares most about.

And now there is no generator here at all, so there is no electricity, and it doesn't make any sense to take out the light bulb alone.

"My lord, if I remember correctly, this light bulb must be supported by a strong electric power. There is no generator here. How should the light bulb be used?" Changsun Wuji couldn't hold back the doubts in his heart, and still looked at Su Feng. raised the question.

and.

He was really curious why there were so many things in Su Feng's pocket, and every time he stretched out his hand, he seemed to be able to take out what he wanted.

All those present who knew the function of the light bulb looked at Su Feng with concern at this moment. Of course they hoped that the light bulb could also be used here.

But the fact that there is no electricity is right in front of us!

"There is naturally a solution to this!" While Changsun Wuji was stunned, Su Feng took out a fist-sized hand generator from his pocket.

The system rewarded him a lot for such a small generator before, and Su Feng didn't care about it at first, thinking that there might be a better opportunity before taking it out again.

Now that such a big loophole has been discovered, it is natural to use these generators.

After careful assembly, Su Feng gently shook the hand-cranked generator, and with the buzzing sound, the light bulb really turned on slowly.

As Su Feng's shaking speed gradually stabilized, the light bulb also reached the most stable effect, and the surrounding gradually began to brighten.

The scene was quiet, and almost everyone's eyes widened!

Especially for those who have never seen a light bulb, they were so shocked that they could not speak at this time. They never thought that besides candles and lamp oil, there are other things that can illuminate.

The most terrifying thing is.

This thing doesn't need to be burned, and it can emit such a powerful light just by shaking it a few times by Su Feng, it's simply unbelievable.

A considerable number of workers couldn't help but want to kneel at this moment. To them, what Su Feng did was like a miracle.

Changsun Wuji and the others looked at each other, and they all saw the shock in each other's eyes.

They have seen such a scene before, and they know that the light bulb has such a powerful effect, but they never knew before that besides the generator, this little gadget brought out by Su Feng can actually generate electricity.

According to the current trend, I am afraid that electric lights will be popularized in steel factories soon, which will not only solve the problem, but also bring unimaginable convenience to oneself.

"My lord, since these light bulbs are all related to steel, we happen to be in the steel factory, can this thing be mass-produced?" Changsun Wuji asked the question he was most concerned about.

In fact.

Ever since he returned to Chang'an, he had been wanting to get an answer, but he didn't find a suitable opportunity to ask.

Hearing Changsun Wuji's words, the others nodded in agreement.

Yes!

Now they are in the steel factory. If the light bulbs can be mass-produced, then from now on, they will say goodbye to candles and oil lamps, and enjoy the same benefits!

Taking this opportunity, Su Feng also briefly explained the structure of the light bulb, from the glass to the tungsten wire inside, including how to generate light and so on.

Especially the most critical part, that is, the tungsten wire in the bulb, can also be barely replaced by copper wire, but the service life will not be too long.

During the manufacturing process of the original light bulb, there will be nitrogen in the light bulb, which can greatly extend the service life of the light bulb.

of course.

It is impossible to achieve this with the current technology. According to Su Feng's expectation, the produced light bulb can only be used for more than a month at most.

But that alone is enough...
