When Mao Geng faced Wang Qinyin, hesitated a little under the expectant gaze of the little beauty. He thought that he could not refuse, so he thought of it and thought of sulfonamide.

Sulfonamide is a product of organic chemistry. Mao Geng believes that early organic chemistry is mostly a chance. As long as you dare to try it, you may be able to fiddle with the red dye "Bailangduoxi", and then you can naturally obtain anti-inflammatory drugs such as sulfonamide.

So, Mao Geng briefly described the prospects of dye chemicals and pharmaceutical chemicals.

Regarding the dyes of this era, the cyan dyes commonly used in them actually came from plate blue (also called horse blue). Isatis root was a traditional Chinese medicine used by later generations in a large number of years. Obviously, the Song people used isatis root in the wrong place. If there were synthetic dyes, then isatis root could no longer be wasted on dyes. Mao Geng believed that for this, dye chemical industry should also be launched earlier.

The success of dye chemical industry will lead to the success of pharmaceutical chemical industry.

Considering that Mao Geng's predictions have always been accurate, even Wang Qinqin was convinced. Since Mao Geng promised to let the two of them participate in the chemistry of special value, Wang Qinqin and Wang Qinyin naturally would not have any objections. The two of them got Mao Geng's promise and left happily.

Mao Geng actually has limited knowledge of organic chemistry. Fortunately, Gu Yongqiang, Mao Group set up one or two organic chemistry laboratories alone. In fact, the investment is not very large. If you are lucky, you may be able to make a name for yourself.

In the following days, Mao Geng entered a new busy period.

Although the three-inflated steam engine was successfully run at no load, it still exposed several problems after adding the load, which is not a big problem, but these small problems cannot be ignored. Mao Geng estimated that in ten days and half a month, these minor problems can be overcome. In other words, half a month later, even if a three-inflated steam engine is basically finalized, this steam engine has reached 120 horsepower, and the horsepower is still too small. The power of the next three-inflated steam engine must reach more than 200 horsepower.

At the same time, Mao Geng and Gu Yongqiang reached an agreement on setting up a separate dye and medical chemistry laboratory. Although Gu Yongqiang was busy shaping lead-acid batteries during this period, this laboratory was related to the interests of time travelers, and it was not as late as in the morning. Therefore, Gu Yongqiang consciously took time to guide the work of this laboratory.

In fact, it is impossible to achieve results soon, but as a professional, Gu Yongqiang has a very good professional level. At least he has set a few basic directions. In Gu Yongqiang's words, with these research directions of outlines, you can avoid detours. Of course, it is impossible not to take any detours. As for when the results will be achieved, it is still necessary to rely on some luck.

After confirming that the bamboo charcoal wire lights were first installed, the travelers spent several costs to carry out the "gift project" for palace lighting.

Based on the principle of safety first, the "Treasure Project" uses DC power. Considering that the transmission distance of DC power cannot exceed one kilometer, the "Treasure Project" includes two small DC generators, two sets of batteries, and of course, it also includes matching enameled copper wire and bamboo charcoal wire electric lamps.

One month later, two sets of lighting equipment were sent to Lin'an. After the equipment arrived, Peng Qinfang was installed and debugged.

On the first day of the March 18th year of Chunxi, Lin'an, on that day, there was a hint of drizzle floating in the sky, and the sky was a little gloomy.

“Now, it’s time to generate electricity.”

It is now 3:30 pm. All the equipment and equipment were installed yesterday and can finally be tested today. Peng Qinfang carefully checked the equipment lines and confirmed that it was correct. Peng Qinfang began to direct the eunuch to promote the fire and generate electricity.

About half an hour later, the steam pressure in the boiler reached the required pressure value. As the air valve opened, the steam turbine began to drive the DC generator to rotate. Peng Qinfang nodded and then closed a switch on the wall of the generator room. At this time, the light fixed on the same wall turned on.

A little eunuch shouted excitedly:

"It's bright! It's bright!"

"It's really bright!"

"The electric light is really bright! Look, look at the filament, it's really bright!"

－－－－－－－

Looking at the excitement of the eunuchs, Peng Qinfang smiled and said:

"Okay, let's try each light."

Zhao Xing was in the study with Zhou Bida, Liu Zheng, and the Crown Prince Zhao Dun while discussing matters, and when the eunuch accompanied Peng Qinfang in, Zhao Xing could not wait.

"The official is ready to turn on the lights now."

Zhao Xing smiled and said:

"Then turn on the lights, turn on the lights."

Peng Qinfang signaled to the little eunuch. The little eunuch walked over and closed a switch on the wall. Then the light on the wall lit up. The little eunuch closed a switch on the table again, and the light on the table also lit up.

It was still during the day. As soon as the lights on the wall were turned on, it immediately made people feel that the room was particularly bright.

A beautiful cover was placed on the electric lampshade on the table, just like the lamps of later generations. Zhao Xing walked over, felt the brightness of the lamp, and nodded with satisfaction.

Zhou Bida couldn't help but feel curious and tried to turn on the light on the wall. Zhao Sheng smiled and said:

"This electric light is really bright, better than a candle! However, this electric light is so complicated that it must cost a lot, so the people can't afford it! Peng Aiqing, according to fact, how much does this set of electric light cost?"

Peng Qinfang was afraid that Zhao Xing would not use this electric light. If Zhao Xing did not use it, it would at least be very unfavorable to promote the electric light. So Peng Qinfang quickly explained:

"I'm sure that this electric light is not very expensive, but it actually saves money than candle lighting. This set of electric lights does cost a lot. However, the special zone is testing AC lighting, which is not as direct current as here. Electric light lighting will eventually use AC power. Once AC power is used, the cost of using electric lights is quite low, and even ordinary people can afford electric lights. Officials don't have to worry about this!"

"What is DC power? What is AC power?"

Lao Peng accidentally threw out DC and AC, so Liu Zheng couldn't help but find the root cause. At this time, even Zhao Xing thought to himself that there are many concepts and terms in the country of Ha Tang, and it is endless.

Lao Peng felt a little regretful and thought to himself that he had missed his words.

Historically, DC power was used first, and Edison's bamboo charcoal wire electric lamp was used for DC power. Later, Tesla invented AC power. The advantages of AC power were very obvious, mainly reflected in the transmission advantage. If the DC power transmission distance exceeds one kilometer, it is not easy to use. AC power transmitted by transformer can theoretically be transmitted to any place far away.

But Edison suppressed AC power for many years, and Tesla and Edison broke the face. Of course, the reason for this is that it is just because of the word "money". Edison has invested so much in DC power, and of course he has to make enough money in DC power before he is willing to let go.

Peng Qinfang then explained for a long time, and the audience could understand half or not.

Zhao Xing just didn't understand it, but Zhao Xing was really happy today. Zhao Xing smiled and said:

"I hear it as false, but I see it as true. What Peng Aiqing said is profound and difficult to understand. I decided to go to Taiwan for inspection this month and see how the AC power is different."

"Officials, I think it's not possible. Officials need to look at AC power, but it's better to let the Special Administrative Region send an AC power to Lin'an." Zhou Bida immediately advised Zhao Shen to give up his idea of ​​going to the southern tour.

"I agree that the government should put the country first, and I ask the government to dispel the intention of the southern tour."

"I have decided, so don't say much."

Peng Qinfang didn't think anything. The boss of the later generations of the Celestial Empire would always take a plane to run around the world. Zhao Sheng went to the Special Administrative Region to check it out, maybe it was a good thing.

Zhao Dun's mood was a bit complicated. When his father went to the south, he had the opportunity to supervise the country. It was said to be a good thing, but when his father went to the special zone, Zhao Han might have added points. Therefore, it is hard to say whether it was a good thing or a bad thing in the southern tour.
