"Success!" Jiang Xingchen stood up and asked loudly, "Light bulb?"

The material aspect has already been solved, because tungsten was not found, according to the memory of the previous life, Jiang Xingchen chose the carbonized bamboo silk. The difficulty lies in the production process of the bulb and the experiment of vacuuming. This is because not only does it drain oxygen and energy, but it also increases the thickness of the glass to resist pressure, which requires a lot of experiments.

As for the inert gases such as argon gas rushing into the bulb, the current technology of Xingchen Ling cannot reach it. First of all, the separation of gases has not yet been studied. Of course, with electricity, compressors can be studied, whether it is gas separation or ammonia synthesis, which will play a significant role in future development. In particular, with synthetic ammonia, it will play a huge role in the development of weapons in the future.

"That's right! For such a long time, our glass production technology is very mature, and we have already researched certain results, and the process problem was quickly solved. The vacuum reference is a pump, and I don't know if the effect will work. But the light bulb is indeed lit!" Xian Ning said excitedly, the world's first electric light was born in her own hands, which really made her so excited.

"Let's go, let's take a look!" Jiang Xingchen didn't care about writing any novels, and Mei'er's advice to not let work was left behind, and she trotted out of the door......

Inside the laboratory, the thick curtains all around were falling, and it was pitch black. There was silence in the room except for the sound of breathing, and everyone waited for Jiang Xingchen to shake the generator with his own hands.

"Buzz~" The sound of the rotor turning at high speed sounded, and a little light appeared in the middle of the room, illuminating more than a dozen faces around.

The flickering lights made Jiang Xingchen's face flicker a little, but the happy smile could be seen clearly by anyone. Just like Xian Ning said. The first electric light was born, and the meagre power generated by a hand-cranked generator alone was about as bright as lighting several candles at the same time.

"Stars. How is it?" asked Xian Ning with a smile.

"Very good!" Jiang Xingchen nodded with satisfaction and said, "Make a bigger generator again." Use a steam engine to drive the rotor and try again. ”

"Okay, I'll start immediately, and call Mei'er and Grandpa Fu over tomorrow night to feel the electric light together......!"

After Jiang Xingchen returned to his ward, he couldn't do anything, just like Xian Ning, the excitement brought by the successful development of the electric lamp, no matter how good his mentality was, he couldn't control the mood fluctuations in his heart.

The story of the novel could not be written, and he didn't even fall asleep until late. What appeared in my mind was the appearance of the stars leading the lights of thousands of homes in the future.

It wasn't until late at night that Jiang Xingchen's mood calmed down a little, as he thought of his next plan. The invention of the light bulb is only the beginning, and the construction of the power grid is the big one. The construction of power plants and the laying of lines need to be slowly explored from scratch, and he has no experience and knowledge in this area.

In addition, it is necessary to train professionals, electricity is not a joke, and if you don't get it right, you will die...... There is also research on transformers. The study of enameled wire, as well as the design and use of series and parallel connection after connecting to the household. So this is just the beginning, it is still very early to really popularize electricity, and there are many problems that need customer service.

Unconsciously. Jiang Xingchen fell into a deep sleep, and when he woke up, it was already the next morning, and the sun was already rising.

Sit up slowly. On the table next to it is warm rice porridge, as well as fried wild pheasant eggs and a few side dishes. Jiang Xingchen couldn't help but smile warmly. At first glance, it was prepared for herself by Mei'er. Although they now have someone to serve them, Mei'er still insists on cooking every day after he has been injured.

After washing up and having breakfast. Jiang Xingchen sent someone to find Xian Ning, Grandpa Fu, and Mei'er. The light bulb has been invented, and then the grid plan is to be implemented, which is another mega-project, a power plant, a wiring lay, and a household.

Grandpa Fu and Mei'er talked while remembering, allocating funds, materials, construction, and training professionals. Xian Ning also lost the excitement of yesterday, and was very serious. Just like Jiang Xingchen said, there are still many difficulties to overcome in the future, and they are very dangerous.

Not to mention, the days ahead need to go hand in hand, power grid planning, telegraph development, and the production of clocks and watches.

"It seems that some of the days ahead will be busy!" said Xian Ning secretly in her heart. At the same time, there is some expectation, after the injury is healed, she is more enthusiastic than before. On the one hand, she is passionate about research and wants to see these great inventions born in her own hands. On the other hand, it is also a reward for Jiang Xingchen. When she first woke up, Jiang Xingchen said that it was a joke to let her work hard in the future, but she took it seriously.

"Brother, should we bring Old Man Duan Qingshi here?" Mei'er asked, the power grid is going to enter the house eventually, how can it be done if you don't tell Duan Qingshi.

"Go to the Lord's Mansion at night and see the effect of the electric lights with your own eyes. I'll talk to him later!" Jiang Xingchen said.

"Sir, if you put it into the power grid plan immediately, you will have to use the money to build the railway...... And we have more than one power grid, and there must be one over there in the steel plant!" said Grandpa Fu with a frown. If the development of various places is accelerated at the same time, the funds are really too scarce, and every project is the big head.

"The dividends of this batch of paper and cement are coming soon, and there are also a lot of sales of perfume, soap, tea, porcelain, clothing, and honey, so let's use them for preliminary preparations!" Jiang Xingchen said.

"Sir, how can there be so many! Although these products earn a lot, they also pay a lot. The annual investment in the new city is more than 300 million, and we also have tens of thousands of craftsmen, private soldiers, and soldiers to support, and the number of laborers in various places is hundreds of thousands, all of which need to spend money...... Also, fighting these battles also consumes a lot. This year's tourism industry in the territory is simply losing money, plus those demon beasts and wild wolves......"

"Stop!" Jiang Xingchen hurriedly raised his hand, every time Grandpa Fu calculated this for him, his head was big.

"Just say, do you have any money invested in the early stage?" Jiang Xingchen asked.

"Yes, there is, but we have to leave a batch of emergency responses, and we can't put all of them into it! The construction of the power grid not only requires site selection and surveying, but also has to have a line erection or something, and the cost of preliminary preparation is also a lot!" Grandpa Fu continued to complain.

"It's easy to deal with emergencies, the construction of the railway will not be so fast, use that first...... Han Xiaowu's construction over there is not a matter of a short period of time, and the money over there can be called!" Jiang Xingchen's voice fell, and when he saw that Grandpa Fu was about to speak, he hurriedly waved his hand and said: "That's it, it won't be long before there will be money, I promise!"

Grandpa Fu finally nodded and stopped talking, Jiang Xingchen couldn't help but breathe a sigh of relief, and both Xian Ning and Mei'er couldn't help but sigh.

The day passed quickly, and as night fell, a generator the size of a small round table was sent into the Lord's Mansion in Newtown. At this time, the courtyard was already full, waiting to see the lights come on. (To be continued......)
