The most grand festival of this era has just passed, and people are still talking about the various exciting aspects of the Lantern Festival Gala, among which the magic performed by Wang Yunzhi is naturally a focus.

As for Liu Guo’s report, it has attracted people to pay attention to the new term “chemistry”.

"Brother, you are very knowledgeable. Do you know what 'chemistry' is going on?"

"Ahem, this 'chemistry' is known to the following point, which is a secret of Taoism that has not been passed down. In the Tang Dynasty, Taoism refining alchemy techniques were said to be the descendant of Taoism. It can be seen from this that it is not surprising that the Harbin and Tang Dynasty are proficient in Taoism alchemy techniques."

"So that's it! Brother said it right."

This is a conversation between passers-by A and B. In fact, there are various far-fetched statements surrounding the new word "chemistry".

On this day, Mao Geng was holding a meeting in the conference room. The topic of the meeting was a plan for electric lights.

Because of the Lantern Festival Gala, this electric light is no longer a secret, but there is still some controversy among time travelers about whether it is practical.

"This bamboo charcoal wire electric lamp has a lifespan of only a thousand hours. It takes six hours a day to order half a year. Haha, it was originally a durable light bulb, but it turned out to be consumable. I think it would be better to wait until the tungsten wire is pulled out before the tungsten wire is pulled out before the tungsten light is put into the tungsten light. Before that, the problem of power generation and power transmission are definitely a system project. When the tungsten wire is pulled out, it is estimated that there will be mature solutions to the power generation and power transmission problems. It will not be too late to use the light again at that time."

The speaker was Zhao Yuchun. Mao Geng looked at the guy who wanted to get everything in one step. He thought to himself that he didn't know how his father would have such a name that was homophonic to "stupid". It was obvious that Zhao Yuchun was not stupid, but he seemed too aggressive every time. Someone once laughed at Mao Geng's name as similar to "Maohun", but Mao Geng himself had no taboos on this point. Considering that there was a star's name in later generations who was also homophonic to "stupid", this did not prevent Li Yuchun from being glorious.

"What's wrong with bamboo charcoal wire electric lamps? After Edison invented the bamboo charcoal wire electric lamps in 1880, Curry did not invent the tungsten wire drawing process in 1909. It was not until 1910 that the bamboo charcoal wire electric lamps were gradually replaced by tungsten wire electric lamps. In history, bamboo charcoal wire electric lamps were used for thirty years. As for the consumables mentioned by Team Leader Zhao, what's wrong with selling consumables! I think it's good to sell consumables. Those who sell consumables in later generations made a lot of money. At least, as a teacher, I envy others who sell consumables, haha!"

Qian Airu thinks that it would be good to have bamboo charcoal wire electric lamps in this era. Moreover, when Teacher Qian imagined that Edison was counting money when he was selling bamboo charcoal wire electric lamps, he felt that this process could not be omitted.

Mao Geng found it a bit ridiculous, but the black-hearted capitalists in later generations were like this. For example, even 4G technology has matured, monopolists are still making money in 2G mobile phone services, and then 3G mobile phones are late. When 4G is commercialized, 5G technology has actually passed the test. This strategy seems to have been carried forward in the Song Dynasty.

So Mao Geng asked:

"Lao Gu, look, when can I pull out the tungsten wire?"

"It's hard! After He Chian went to Lin'an, he contacted Xin Qiji and found black stone, which is tungsten ore in Dayu, Jiangxi. This is not difficult. In history, Dayu's tungsten ore can be picked up by any tungsten ore. He Chian is from Wugang. If he doesn't know about Dayu's tungsten ore, it's really unreasonable. The problem is that it's not difficult to obtain tungsten trioxide from calcination of tungsten ore, but it's best to reduce it from tungsten trioxide to tungsten metal, so it's better to reduce it with hydrogen, so it's necessary to use electricity.

Solution, haha, if you have to use electrolysis, you have to build a high-power power station. Also, no one has done the pulling tungsten wire before, it will take more than three months to explore the pulling process. Moreover, the simple pulling tungsten wire of Currich is still not up to date. It seems that some oxide is required to finally make tungsten wire that does not sag. In 1909, Currich pulled tungsten wire, but it was not until 1922 that did not sag. This is a very difficult thing."

Speaking of later generations, Dayu in Jiangxi was known as the "Tungsten Capital of the World", so He Chian was of course familiar with it.

But Dayu discovered tungsten ore by itself. For thousands of years, black stones were everywhere in Xihua Mountain in Dayu, but no locals knew that it was a precious tungsten ore. Until 1906, Wu Liheng, a German pastor from the Catholic Gospel Hall in Dayu County, went to Xihua Mountain to view Qingyun Temple and found that everywhere they went, there were all black and shiny stones. Wu Liheng picked up one piece and weighed it, and felt it was very heavy, so he realized that it was a precious ore.

So he picked up a few more pieces and took them back to the church. The following year, Wu Liheng returned to China with stones. After identification, he found that these ores contained a rare metal - tungsten.

Since then, Dayu's black stone has been continuously exported to Germany and countries around the world.

However, in the Song Dynasty, it was not called Dayu, but "Dayu". Therefore, He Chian took some trouble to find the black stone in Dayu - that is, tungsten ore.

However, finding tungsten ore only has the raw materials. You have to admit that there is still a long way to pull out the tungsten wire.

"Damn! Lao Gu, it's not that difficult! Don't forget that we are time travelers and can take shortcuts in everything." Zhao Yuchun thought that Gu Yongqiang was deliberately exaggerating the difficulty.

Lin Lishi curled his lips and said:

"I said to Team Leader Zhao, we can't look at problems from the perspective of farmers and entrepreneurs. It's easy to copy the technology, but you may be used to copying the technology, and think that the technology is just that. This is also my professional category. Lao Gu did not deliberately exaggerate the difficulty, but powder metallurgy is still difficult. The theory is simple, and the process has to be explored a little by little by little. I'm still waiting for tungsten metal to be smelted earlier. Tungsten metal is a good thing, and I'm also pointing at it to produce high-strength alloy steel."

Zhao Yuchun's face suddenly felt a little uneasy. When Lao Qiu saw it, he immediately interrupted:

"Okay, okay, let's not talk about tungsten for now. I will put the horoscope without any words in advance."

Today's meeting made Zhao Yuchun feel a little distorted. Now, when you see Zhao Yuchun being depressed, you think you deserve it. Lao Qiu immediately got back to the point:

"Since history has proved that the lifespan of bamboo charcoal wire bulbs can reach 1,200 hours, ordinary people save some use, and it will be almost a year long. There is no problem with commercial use. Edison has sold bamboo charcoal wire bulbs for 30 years. We can sell them for three years! No matter whether it is a consumable or not, it is better than adding oil in one or two days. Today's meeting, for nothing else, is to develop a technical plan and promotion plan around this bamboo charcoal wire bulb."

In fact, when it comes to specific solutions, it is not very difficult to technically produce power. Steam turbine power generation is already in operation, and power transmission and transformation are not too difficult. Drawing copper wires is a piece of cake. As for the insulation of copper wires, it has basically passed the test some time ago. The insulation layer of copper wires outsourced is currently the method of repeated paint brushing. Well, it is not much different from painting. Although there are flaws in safety performance, it can be considered as passing the test.

Regarding promotion, there is no pressure for the time being, because the power is not as luxurious as it can be used up, and many projects are queuing up for electrolysis, and the power is not oversupply but serious shortage. Therefore, the first phase of the electric light project is only limited to the public and some high-end people in the SAR.

However, in this imperial society, with good things, at least the Emperor of the Song Dynasty must also share it. No matter from the aspects of political correctness and experience and interests, this must be considered.

Therefore, the meeting decided to specially create a power generation light system for the Royal Palace of the Song Dynasty. No one objected to this. All time travelers came from the 21st century. From the perspective of advertising, this was worth it anyway.

After a break, Mao Geng rubbed his temples and was about to relax for a moment, but when Mao Geng stepped into his office of the Chief Executive, he immediately heard Wang Qinqin's voice:

"The meeting finally ended! Chief Mao, we have been waiting for you here for a long time."

When he saw that it was Wang Qinqin who was troublesome, Mao Geng was a little overwhelmed, but when he saw Wang Qinyin's eagerness to speak, Mao Geng smiled and asked:

"Is there anything wrong?"

"Qinyin and I want to learn chemistry. Let's talk to Mr. Gu, how about let's evolve the chemistry group?"

Mao Geng was suddenly a little amused and confused. Are you going to the Geju Academy casually? Besides, it’s okay for girls to learn chemistry. It feels very inconsistent to let Wang Qinyin rush for the acids and alkalis. The key is that the chemistry group is going to test the various explosives/pharmaceuticals and eject medicines. It’s really a high-risk career, so it’s better for women to not touch them. As for, Gu Yongqiang doesn’t care about chemical pollution at all, that’s a trivial matter.

Seeing a graceful beauty like Wang Qinyin, Mao Geng shook his head and thought to himself, why are you going to make fun with Wang Qinyin?

"It's not easy to learn chemistry. What's more, Lord Zhu Xi is now the president of the Geju Academy. Do you think President Zhu will accept a woman entering the Geju Academy?" Mao Geng imagined Zhu Xi's discrimination against women and thought to himself, even if I agree, Zhu Xi will definitely not agree. If you want to enter the Geju Academy, there is no door!

Wang Qinyin couldn't help but say:

"But, Tan Wangdi is also a woman. Isn't she fiddling with chemistry too? Since she can do it, why can't we do it!"

Speaking of this, Wang Qinyin's words were quite coquettish, which was a bit rare.

Because of the glass firing, Tan Wangdi did come into contact with soda ash early and entered the chemistry sect, but Tan Wangdi was just Mao Geng's disciple and had nothing to do with the Jujube Academy led by Zhu Xi.

Mao Geng then explained:

"Tan Wangdi learned some chemistry from me, and she was not in the chemistry group of the Geju Academy."

Of course, Mao Geng would not hand over all the skills to Zhu Xi. That was actually a gesture. The short and flat and fast ones were still in the hands of Mao Geng. Generally, only long-term projects would be handed over to the Geju Academy, which would be the same in later generations.

Seeing that the two of them were still unhappy, Mao Geng continued to persuade:

"Well, you might as well learn about textiles, clothing or cosmetics. I can say hello to Teacher Qian and the others. You can learn from them. How about it?"

"No, I must learn chemistry." Wang Qinyin recognized it this time, looking pious.

Mao Geng remembered that there were people pleading with him in the past few days and wanted to install the human chemistry group. What's ridiculous is that even Yan Rui recommended a distant relative to the chemical group yesterday. Mao Geng smiled bitterly, but unexpectedly, chemistry became a popular major that was sought after overnight.
