Mao Geng faced Wang Qinyin, under the expectant gaze of the little beauty, he hesitated a little in his heart, and he couldn't refuse when he thought about it, so his mind was spinning, and he thought of sulfonamide.

Sulfonamide is a product of organic chemistry, Mao Geng believes that most of the early organic chemistry is a matter of luck, as long as you dare to try, you may be able to fiddle with the red dye of "Bailang Duoxi", and then it is logical to obtain sulfonamide, an anti-inflammatory drug.

So, Mao Geng roughly described it and talked about the prospects of dye chemicals and pharmaceutical chemicals.

Regarding the dyes of this era, the commonly used cyan dye is actually from Banlan (also called Ma Lan), and Banlan root is a large number of heat-clearing and detoxifying Chinese medicine used in later generations, it is obvious that the Song people used Banlan root in the wrong place. If there is a synthetic dyes, then the root of the plate can no longer be wasted on the dyes, Mao Geng believes that for this, the dye chemical industry should also be launched earlier.

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

Considering that Mao Geng's prophecy has always been very accurate, even Wang Qinqin is convinced, since Mao Geng promised to let the two of them participate in chemistry of special value, Wang Qinqin and Wang Qinyin naturally will not have any more opinions, and the two got Mao Geng's promise and left happily.

Mao Geng actually has a limited knowledge of organic chemistry, but fortunately, with Gu Yongqiang, Mao's Group has set up one or two organic chemistry laboratories alone, in fact, the investment is not very large, if you are lucky, you may really be able to make a little famous.

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

Although the three-expansion steam engine was successfully run without load, but after adding the load, it still exposed a number of problems, which is not a big problem, but these small problems can not be ignored, Mao Geng estimates that there are ten days and half a month, these small problems can be overcome. That is to say, half a month later, even if a three-expansion steam engine is basically finalized, this steam engine has reached 12o horsepower, the horsepower is still too small, and the power of the next three-expansion steam engine must reach more than 2oo horsepower.

At the same time, Mao Geng and Gu Yongqiang reached an agreement on the establishment of a separate dye and medicinal chemistry room, although Gu Yongqiang was busy with the shaping of lead-acid batteries during this time, but this room was related to the interests of the traverser, and it was better to be late than in the morning, so Gu Yongqiang consciously took time to come over to guide the work of this real room.

In fact, it is impossible to have results soon, but as a professional, Gu Yongqiang's professional level is still very good, at least a few basic directions have been set, in Gu Yongqiang's words, with these outlines and research directions, you can avoid detours. Of course, it is impossible not to take a detour at all, and as for when there will be results, it depends on some luck.

After deciding to put on the bamboo charcoal wire electric lamp first, the crossing spent a certain amount of money to carry out the "gift project" of the palace lighting.

Based on the principle of safety first, the "Gift Project" uses direct current, considering that the transmission distance of direct current can not exceed one kilometer, and finally, the "Gift Project" includes two small DC motors, two sets of batteries, and of course, also includes supporting enameled copper wire and bamboo charcoal wire lamp.

A month later, two sets of lighting equipment were sent to Lin'an, and after the equipment arrived, Peng Qinfang installed and debugged it.

On the first day of March in the eighteenth year of Chunxi, Lin'an, on this day, there was a trace of drizzle in the sky, and the sky was a little gloomy.

"Now, it's time for electricity."

Now the time has reached half past three in the afternoon, all the equipment and equipment have been installed in place yesterday, and today it can finally be put into trial operation. Peng Qinfang carefully checked the equipment wiring and confirmed that it was correct, and Peng Qinfang began to direct the little eunuch to raise the thermal power.

After about half an hour, the steam pressure in the boiler reached the required pressure value, and as the valve opened, the steam turbine began to drive the DC motor to rotate. Peng Qinfang nodded, and then closed a switch on the wall of the motor room, and the electric light fixed on the same wall turned on.

A little eunuch shouted excitedly:

"It's lit! It's lit up! ”

"It's really bright!"

"The lights are really bright! Look at it, look at the filament, it's so bright! ”

－－－－－－

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

"Alright, let's try each light."

Zhao Yan was in the study at this time with Zhou Bida, Liu Zheng, and the crown prince Zhao Dian while waiting for the electric light test, and when the little eunuch accompanied Peng Qinfang in, Zhao Yan was already a little impatient.

"Kick off the official, now you can turn on the lights."

Zhao Yan smiled:

"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, and then the electric light on the wall turned on, and the little eunuch closed a switch on the table, and the electric light on the table also turned on.

It's still daytime, and when the lights on the wall are turned on, it immediately makes people feel that the room is extra bright.

The electric lamp on the table was covered with a good-looking cover, just like the table lamp in later generations, Zhao Yan walked over, felt the brightness of the table lamp, and nodded with satisfaction.

Zhou Bida couldn't hold back his curiosity, and also tried to turn on and off the electric light on the wall, Zhao Yan smiled and said:

"This electric light is better than a candle! It's just that this electric light is so complicated that it must cost a lot, and the people can't afford it! Peng Aiqing, you tell the truth, how much does this set of electric lights cost? ”

Peng Qinfang was afraid that Zhao Yan would not use this electric light, if Zhao Yan did not use it, at least it would be very unfavorable to the promotion of electric light, so Peng Qinfang hurriedly explained:

"Qi Qi Guan's family, this electric light is not very expensive, in fact, it is more expensive than candle lighting. This set of electric lights does cost a lot, but the special zone is experimenting with alternating current lighting, which is not as good as direct current here, and the electric lighting will eventually use alternating current, and once alternating current is used, the cost of electric lighting is quite low, and even ordinary people can afford to use electric lights. Officials don't have to worry about this! ”

"What is direct current? What is alternating current? ”

Lao Peng accidentally threw out the direct current and alternating current, so he couldn't help but get to the bottom of it immediately. At this time, even Zhao Yan said in his heart, there are many conceptual terms in the Tang Kingdom, and they are endless.

Lao Peng regretted it a little, and said that he had accidentally leaked his mouth.

Historically, direct current was used first, Edison's bamboo charcoal wire lamp is used for direct current, and later Tesla understood that alternating current, the advantage of alternating current is obvious, mainly reflected in the transmission advantage, direct current transmission distance is not good for more than one kilometer, and the alternating current transmitted by voltage conversion can theoretically be transmitted to any distant place.

But Edison suppressed alternating current for many years, for which Tesla and Edison tore their faces. Of course, the reason why this is the case is just because of the word "money", Edison invested so much in direct current, and of course he was willing to let go only if he had enough money on direct current.

Peng Qinfang then explained for a long time, and everyone present listened to it for a long time.

Zhao Yan only seemed to understand, but Zhao Yan was really happy today, Zhao Yan smiled:

"Hearing is false, seeing is believing, Peng Aiqing's words are profound and difficult to understand, I decided to go to Taiwan this month to inspect in person, and by the way to see how AC is different."

"Officials, ministers think it's impossible. The officials want to see the alternating current, so why not let the special zone send an alternating current to Lin'an. Zhou Bida immediately advised Zhao Yan to dispel the idea of visiting the south.

"The minister seconded the proposal, the official family should give priority to the community, and the minister asked the official family to dispel the intention of the southern tour."

"I have made up my mind, so I don't need to say more."

Peng Qinfang didn't think anything, the boss of the Celestial Empire in the future would take a plane to run around the world at every turn, and Zhao Yan went to the Special Economic Zone to have a look, maybe it was a good thing.

Zhao Dan's mood is a little complicated, his father is touring the south, and he has the opportunity to supervise the country, which is said to be a good thing, but his father went to the Special Economic Zone, and Zhao Lu may have a big bonus again. Therefore, it is really difficult to say whether it is a good thing or a bad thing to do about the southern tour.
