Chapter 188 How to Achieve Electrification of Ming Dynasty

When making alcohol, the raw materials are actually similar to those for brewing wine. There are only three types: grains, potatoes and molasses. After all, in a broad sense, alcohol is further purified liquor.

The raw materials of cereals include sorghum, corn, wheat, etc. At present, there is no corn in the Ming Dynasty, and sorghum and wheat are not enough as food, let alone as raw materials for alcohol.

The same goes for molasses. The Ming Dynasty was not yet extravagant enough to use sugar to make wine, so the only raw material available was sweet potatoes, which were plentiful and filling.

As for the manufacturing process, in fact, the early stage is the same as wine making, which is to chop and then steam to destroy the cell walls so that the starch and water can fully blend to form a saccharified liquid.

Then rinse repeatedly with clean water to remove impurities and retain only starch. After standing for a while, saccharifying enzyme needs to be added for sufficient saccharification. However, there was no chemical industry in the Ming Dynasty, let alone food chemical industry, so saccharifying enzyme can only be replaced by koji.

Once the koji and saccharify liquid are fully fermented, distillation can begin.

There were no modern distillation towers in the Ming Dynasty, so Li Han designed one himself. The distillation tower could be replaced by a ceramic tank, and as for the conduit, since there was no stainless steel, it was okay to temporarily use bamboo tubes instead.

In fact, the manufacturing process of alcohol is relatively simpler than that of liquor, because there is no need to consider the taste. Although the distillation process is a bit cumbersome, it can still be achieved.

The focus is on final purification and removal of impurities, which can be achieved through multiple distillations.

After designing a complete set of processes, Li Han suddenly realized that although he had not learned anything else during this period, he had become more and more proficient in drawing drawings.

After copying the historical documentary for promotional purposes to a USB flash drive, I began to wonder whether it was time to start the electrification of the Ming Dynasty.

Although solar energy is a clean energy, it has too many disadvantages. It is OK for charging computers and mobile phones, but if we want to promote industrial development,

The fuel for generating electricity is ready-made, just coal. Now the Ming Dynasty has achieved steamization and coal has been mined on a large scale.

The principle of a coal-fired generator is relatively simple and can be understood with high school physics.

You must first burn coal in a boiler to boil water, and then continuously pressurize the steam to obtain high-temperature and high-pressure water vapor.

The steam then enters the turbine, which spins blades and converts thermal energy into mechanical energy.

Mechanical energy is used to drive the generator rotor to rotate. At this time, Faraday's principle comes into play and the rotor can generate electrical energy during the rotation of the magnetic field.

It sounds complicated and is not easy to implement. Although there are ready-made designs, Ming Dynasty's manufacturing technology still needs to be improved, and the most critical thing is the materials.

However, this is still the easiest first step in the entire electrification process!
Even if the generator can be built, how to transmit electricity is a big problem.

If direct current is used, the Ming Dynasty does not have Academician Ma, the electromagnetic patriot, and most of the things he researches are used in military industry.

Alternating current, how to solve the problem of high voltage?

There are also transformers, substations, and so on, not to mention the vast network of electrical wires.

Or, how about using Edison's method?
No, his system is not suitable for long-distance transmission, and it requires the construction of multiple power plants, so the economic benefits are not obvious.

Tesla's approach is more suitable for long-distance power transmission and centralized power generation, which is more conducive to the construction of cluster factories and large-scale production.

It seems that AC is the most suitable.

Li Han felt numb when he looked at the densely packed list of manufacturing processes and professional terms he had written.

It would have been great if I had known that I would study engineering. Why study history?

All things are difficult at the beginning, so let’s start from the first step and solve the generator first.

This thing is not like making alcohol. You have to consult a professional. Xu Nian is a gun maker, and I don't know how much he knows about electrical engineering. Besides, he has to figure out the production process of the 56 semi-automatic first.

Well, I had to find a suitable electrical expert first. Then, I wrote a reply to Zhu Yuanzhang, put the boxes of wine into the mailbox, and finally sent the letter and the USB drive over. I was already sweating profusely.

Just when he was about to find a bottle of Coke to drink, he suddenly realized that the Coke he bought with the wine was missing.

Where is my huge box of Coke?
Li Han was stunned for a moment. He looked left and right, and suddenly he remembered, could it have been moved into the mailbox along with the wine?
Look at how you've done this. You must have been too busy. Forget it. Just give it to Lao Zhu as a gift.

He returned to the house, took a big gulp of boiled water, picked up his phone, took a beautiful photo of the sandalwood box containing the golden needle gun, and then sent it to Xu Nian.

After a while, Xu Nian replied to the WeChat message.

"Old Li, this thing, can't it be... what I'm thinking of?" It was followed by an expression with red hearts in the eyes and drooling.

The corners of Li Han's mouth curled up. This fat guy usually took a long time to reply to WeChat messages. I didn't expect that he replied so quickly this time.

It seems that this guy really doesn't want to see the rabbit before he releases the eagle. Li Han complained a few words and then replied:

"Do you want to?"

"think!!!!!"

Xu Nian replied instantly, and those shocking exclamation marks expressed his extremely urgent mood.

"We'll take the manufacturing process in exchange for the goods."

"Damn it, Old Li, you are really the evil Party A. Even Huang Shiren would never allow you to oppress cattle and horses like this. We agreed on three months, and it's only been a few days?"

From between the lines, Li Han could clearly feel that Xu Nian was very anxious and in a very anxious mood. He might even be cursing at himself, calling him an evil capitalist who was going to hang himself from the street lamp.

"I know you are anxious, but don't worry. You will get it when the manufacturing process is designed."

At this moment, Li Han was like a devil seducing ignorant young boys.

"I've checked it for you. The golden appearance almost blinded my eyes. This golden needle gun can only be described in one word: exquisite workmanship. It's even more exquisite than the one I have. Moreover, it's your exclusive signature model."

"..."

"Old Li, just wait for me!!"

Li Han was stunned. What was this Fatty Xu going to do?
Hey, can he still come here to rob?
Li Han smiled nonchalantly. The bait had been released. If he wanted to get the golden needle gun as soon as possible, he had to evolve from cattle and horses to mules and horses!

"Fatty, do you know an electrical expert?"

"Fatty, Fatty!"

"Why aren't you talking? Did you secretly go to work overtime? Well, you are a teachable kid. Keep up the good work. I'm rooting for you."

Xu Nian didn't reply for a long time. It seemed that he was really working overtime. Li Han put down his phone and started looking for resources on the Internet.

In addition to historical documentaries, he believes that historical films or TV series should also be provided to achieve better results.

After all, movies have a stronger sense of immersion and can resonate more with viewers. Of course, movies about the Ming Dynasty would definitely not work, like "The Blade of the Assassin" and "New Dragon Inn", which would cause panic throughout the Ming Dynasty.

It has to be about the history of the previous dynasty, and it has to be a prosperous era. The scenes have to be grand, and the values ​​have to be positive, so as to enhance the people's sense of identity. What movie should I choose?
Just as Li Han was carefully considering and selecting, suddenly, there was a rapid knock on the door.

"Lao Li, you have the guts to seduce me, you have the guts to open the door!"
