Because it was the first generation of practical steam engines, Yang Heng gave it a resounding name, called the 1Z-3-5 steam engine.

In fact, this is also the first formal numbering method that Yang Heng has adopted to make some finished products created or produced. This is the meaning of a one-cylinder steam engine, and the third generation steam engine is the third generation steam engine, and the fifth improved model.

Even the steam engines made earlier have formal models. The coal mine water pumping was 1Z-2-1 steam engine. The original ones are basically eliminated now. However, they are witnesses of the development of steam engines. Yang Heng named it 1Z-1-L, which means there is no generation of improvements. Instead, he used the word "王" instead, which means temporary model.

Correspondingly, Yang Heng also arranged a special person to start recording and number some other machinery. This workload is quite large and there is a lot of information to be checked, but it is not simply written if you want to write it. Fortunately, Yang Heng has a good habit of making records. Every design and every change has corresponding records, but even these records, if you want to find them, it is quite troublesome.

At this time, the first batch of graduates from the Yang Academy also officially graduated, all of which were from the intermediate class. Among them were Yang Heng’s two followers, Xiao Ming and Xiao Qiang, and two very powerful children with names. However, now they have new names, one is Yang Ming and the other is Yang Qiang. However, it is no longer called followers or long followers, because they are educated, but this one is educated, that is, they can read more and interpret some classics, and it is impossible for them to rely on the imperial examination.

So, now they are Yang Heng's secretary. Naturally, there is no such thing as a secretary in this era. It is better to call him clerks. Yang Heng himself has a fourth-rank position, so it is normal for him to get two clerks.

With a secretary, Changsui is also indispensable. Naturally, Changsui should be called a correspondent in later generations, naturally. Changsui also has a very powerful name, called Xiaohua, a very clever and very loyal child selected by Yang Heng from the Beggars' Sect. He and Yang Heng were also sent to the academy to study. But since he finished learning the Thousand Characters, he has been clamoring to do things for Yang Heng, so this time Yang Heng also pulled him out of the academy and officially became his Changsui, and changed his name to Yang Hua.

In this way, the team around Yang Heng was officially equipped. There were four guards, who were trained by the Yang family themselves, and they were absolutely loyal people. You must know that those around you must be loyal people, otherwise, you don’t know what would happen. Two clerks and one of them followed. In this way, it would be much more convenient for Yang Heng to do things wherever he went, and there was no need to catch people casually to run errands for him.

Similarly, there are two maids in Yang Heng's home. This is also a must-have person. Although Yang Heng does not need them to warm up the bed, some maids still need to do some miscellaneous work. For example, changing clothes and tidying up the bedding. Even if Yang Heng goes out, these two maids will always be with him. Similarly, these two maids are also orphans and have been trained by the academy for several years. In other words, Yang Heng does not need to have no cultural existence around Yang Heng. They are also given to them.

One is called Cuihua and the other is called Xiaofang. However, he is a little younger. Why is that? Because Yang Heng has never thought of matching a maid for a long time, just matching. But some elderly people in the family are basically married now, and Yang Heng can't bear to let them run around. Therefore, after carefully selected by the housekeeper, he found one from the market and the Beggars' Sect. They are all young and not very sensible. After several years of training, they are officially qualified.

"Alang, how should these models be written?" The people around Yang Heng have now officially changed their name, calling Yang Heng Alang. If they call Yang Heng's father, they are the old master. Yang Heng's uncle is the second old master and the third old master. Although it is difficult to pronounce, it is easy to distinguish. Also, all the brothers of Yang Heng's generation are numbered. For example, Yang Heng can be called Dalang, but they are all called Alang. Others, such as Yang Li, are Erlang, until Nian Ge'er is the little Langjun, which means that the little Langjun who has been with Yang Heng for half his life was officially terminated and transferred to Nian Ge'er.

The same is true for girls. Starting from the auntie's aunt to the last one, the little lady is called the little lady, but for them, it has not changed much. Sometimes people call the baby a baby lady, such as the little lady, etc. It is easy to distinguish. They have names in front of them and you won't hear it wrong.

"This, don't rush to number it. First, divide the types. If this is a carriage, put it in one place, it is a sports equipment, put it in one place, and then it is all divided, and it is divided according to the time sequence. I will explain the way of this numbering to you."

This, the letters have appeared in many places. Yang Heng plans to formally take out the twenty-six letters. Now with the academy as the backing, the writing of this pinyin can also be officially put on the agenda. But don’t worry, Yang Heng still needs to arrange the steam engine first.

"Your Majesty, the prince consort is asking for a visit outside." "Xuan."

"Why, learn literature, why have the time to come to me today? Haven't you been avoiding me all the time?" As soon as they met, Li Er teased Yang Heng. Yes, under normal circumstances, if Li Er didn't call him, he wouldn't come.

"Your Majesty, I have something to ask for advice." "Oh, I have something to say." "Your Majesty, I want to build a power station." "Your Majesty, I want to build a power station." "Your Majesty, I want to build a power station, and windmill power generation, and livestock power generation are not power stations?" "Yes, Your Majesty, I want to build a power station driven by a steam engine this time. I want Your Majesty to specifically approve a yard as the site of the power station for use. Moreover, this place will not be allowed to live in the future. Even the surrounding yards, it is best not to let people live there again, because after this place is built, there will be quite a lot of noise."

"If you don't study the train, what kind of power station will you build?" "Your Majesty, this power station is good for our Tang Dynasty. This steam engine is the first practical steam engine I have made. It would be a pity that I didn't build a power station, but it still doesn't meet the standards for putting it on the train." "Tell me, this power station can drive several electric lights." "Your Majesty, I plan to supply power to the entire Chang'an City, and the generators of each company can be regarded as emergency generators."

After Yang Heng's explanation, Li Er understood what Yang Heng meant, "Okay, I'm sure, but I won't allocate funds from the court to you. You need to pay everything yourself."

"Sure, this is all you need to allow me to charge the electricity bill." "How about the electricity bill?" Yang Heng explained the matter about the electricity bill again, "Your Majesty, I am a business that is losing money and gaining publicity. You won't ban this, right? You know, all wires cost money, and wires are made of copper."

"It's up to you, as long as you pay taxes, it's done." Well, now that Yang Heng is about to have a deal, Li Er is watching the tax.

What did Yang Heng plan? He paid for this wire, and naturally he owned the wire. He was not even worried about being stolen. You know, in this era, if you want to steal electric wires, few people dare to steal electric wires. Moreover, Yang Heng only needs to do a few electric shock tests. I guess no one will steal electricity. Naturally, there may be many people who dare not use electricity. Yang Heng is not worried. You said that if the neighbors were in the bright hall all night, they would not be greedy.

For electricity bills, Yang Heng planned to have five copper plates per bulb per month. If you pay the annual fee, it would be fifty copper plates a year. If you buy a new bulb, you have to exchange it with an old bulb. This does not cost money. Why not install an meter? It’s not that Yang Heng can’t make it, but Yang Heng feels that it’s not cost-effective to make the meter. Do you think this meter costs money or not? But the production cost is not low. At this time, it’s not Yang Heng’s previous life, with a developed industry.

Also, Yang Heng would directly make the light bulb into twenty-five watts. This way, if you order a month, you won’t waste much electricity. Moreover, as long as Yang Heng doesn’t make it, no one can use it. If it doesn’t sell it, who can use it? That’s it.

I have to say that this steam engine is really a good thing. It can directly light up the night in Chang'an City, and it does not limit electricity. Even ordinary families will keep it on. However, Yang Heng is really not worried. Although the steam engine is practical, for energy conservation, if you don't turn on the light, it is similar to the consumption of turning on the light. Naturally, Yang Heng doesn't need to worry about these. This is a low-profit product, but low-profit does not mean a low income, right? A farmer is a light bulb. A better family will naturally have a few more. For rich families, it requires several light bulbs to be installed in a room, a family, or hundreds of light bulbs. Do you think the total profit is high or low?

It is even possible that this electricity will become one of the pillar industries of the Yang family. However, the railway cannot be the Yang family's industry. Perhaps the railway will be a cooperative project between the Yang family and the Royal Family. In short, Li Yuan has invested considerable funds in it.
