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

In fact, this is also Yang Heng's latest way to use a formal numbering method for some creations or finished products for the first time, this 1Z is the meaning of a cylinder steam engine, 3, it is the third generation of steam engine, and 5 is the fifth improved model.

Even the steam engine made earlier also has a formal model, the coal mine is used for pumping, it is the 1Z-2-1 steam engine, the original ones are basically eliminated now, however, they are the witness of the development of the steam engine, Yang Heng named it 1Z-1-L, that is, there are no generations of improvements, but a temporary word is used instead, which is the meaning of the temporary model.

Correspondingly, some other machinery, Yang Heng also arranged a special person to start the record, and numbered, this, the workload is quite large, there is a lot of information to check, but it is not simply to write it, fortunately, Yang Heng has a good habit of making records, every design, every change, there are corresponding records, but these records, want to find, it is also quite troublesome.

At this time, the first batch of graduates of Yang's Academy also officially graduated, and these were all graduated from the intermediate class. There are two followers of Yang Heng Xiao Ming and Xiao Qiang, two dolls with very powerful names, but now they have new names, one is called Yang Ming and the other is called Yang Qiang, but now they are no longer called followers, or long-term followers, because they are educated, but this one is literate, that is, more literate. Able to decipher some classics. And let them rely on the imperial examination. That's impossible.

Therefore, now the two of them are Yang Heng's secretaries, naturally, there is no such thing as a secretary in this era, and they are still called scribes, and Yang Heng himself has the position of Sipin, and it is normal to get such two scribes.

This has a secretary, and a long-term follower is also indispensable. Naturally, this Changsui should be called a correspondent in later generations, naturally, this Changsui also has a very powerful name, called Xiaohua, is a very clever and loyal child selected by Yang Heng from the beggar gang, he, Yang Heng was also sent to the academy to study, but since he finished learning the thousand-character text. I was clamoring to do something for Yang Heng, so. This time, Yang Heng also pulled him out of the academy, officially became his long-term follower, and changed his name to Yang Hua.

In this way, the team around Yang Heng is officially complete, there are four guards, this is the guard trained by the Yang family itself, and it is also an absolutely loyal person, you must know Lu Dao, and those around you must be loyal people, otherwise, I don't know what will happen to Lu Dao, two scribes, one long-follower, in this way, it will be much more convenient for Yang Heng to go to do things, and there is no need to arrest people casually to run errands for him.

Similarly, there are two living maids in Yang Heng's home, this is also a necessary person around him, although Yang Heng does not need them to warm the bed, but some chores still need to be done by maids, such as changing clothes, tidying up the bedding, and even saying that if Yang Heng goes out, these two maids have always been by his side, similarly, these two maids are also orphans, and they have been cultivated by the academy for several years, that is to say, Yang Heng does not need to have no culture around him, the two of them, Yang Heng also gave them a strong name, One is called Cuihua, and the other is called Xiaofang, but the age is a little younger, why is this so, because all along, Yang Heng really didn't think of matching the maid, that is, matching, but some of the old people in the family are basically married now, and then let them run around, Yang Heng can't bear it, so after careful selection by the housekeeper, he found one from the human market and one from the beggar gang, all of whom are young and not very sensible, and after several years of training, they are officially qualified.

"Ah Lang, how should these models be written?" The people around Yang Heng have now officially changed their titles, calling Yang Heng Ah Lang, if they call Yang Heng's father, it is for the old master, Yang Heng's uncle is the second old master, the third old master, although it is more difficult to speak, but it is easy to distinguish whether it is not, and the brothers of Yang Heng's generation are all numbered, such as Yang Heng can be called Da Lang, but they are all called Ah Lang, others such as Yang Li is Erlang, until Nian Ge'er is Xiao Langjun, that is to say, Xiao 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 female babies, starting from the eldest lady of the girl, to the last one called the little lady, but for them, the change is not very big, sometimes some people call the baby the baby little lady, what little lady little lady, etc., this is easy to distinguish, they have a name in front, you will not hear it wrong.

"Well, don't be in a hurry to number it, first divide the types, such as this is a carriage, put it in one place, this is a sports equipment, put it in one place, and so on, and according to the chronological order, I will explain to you the way of numbering."

This, the letters have appeared in many places, Yang Heng plans to officially take out the twenty-six letters when he needs to, and now with the backing of the academy, the compilation of this pinyin can also be officially put on the agenda, but don't worry, now Yang Heng still needs to arrange the steam engine first.

"Your Majesty, the horse is outside asking to see you." "Xuan."

"Why, Xuewen, how did you have time to come to me today, haven't you been avoiding me all along?" As soon as they met, Li Er teased that Yang Heng was coming, yes, under normal circumstances, Li Er didn't call him, he wouldn't come.

"Your Majesty, the minister has something to ask for." "Oh, there's something, say." "Your Majesty, the minister wants to build a power station." "Power station, tell me, what is a power station, what is a power station, what is windmill power generation, and animal power generation is not a power station?" "Yes, Your Majesty, the minister is going to build a power station driven by a steam engine this time, and the minister wants His Majesty to give a special grant to a workshop as the site of the power station to use, and this place will not be allowed to be inhabited in the future, that is, the surrounding workshops, it is best not to let people live anymore, because after this place is built, there will be considerable noise."

"If you don't study that train, what kind of power station will you build." "Your Majesty, this power station, but we Datang has a good name, this steam engine is the first practical steam engine made by the minister, it would be a pity not to build a power station, but it is not up to the standard of putting it on the train." "Tell me, this power station can drive a few electric lights." "Your Majesty, the minister plans to supply power to the whole Chang'an City, and the generators of each family can be used as emergency generators."

After Yang Heng's explanation, Li Er understood what Yang Heng meant, "Okay, I'm right, but I don't want to allocate funds to you from the imperial court, you need to do everything yourself." ”

"Cheng, this, you only need Your Majesty to allow the ministers to collect electricity bills." "Electricity, how do you say it?" That, Yang Heng explained something about the electricity bill again, "Your Majesty, this is a loss-making deal, this, you won't ban it, you must know that this wire costs money, and the wire is made of copper." ”

"Yes, this is yours, as long as you pay taxes." Okay, now that Yang Heng is going to have a deal, Li Er will look at the tax.

What did Yang Heng plan to do, this, the wire, was made at his own expense, and this wire was naturally his ownership, and even, he was not worried about being stolen, you must know that in this era, if you want to steal the charged wire, there are really few people who dare to steal the electricity, and Yang Heng only needs to do a few electric shock tests, it is estimated that everyone will not steal electricity, naturally, there may be a lot of people who dare not use electricity, this Yang Heng is not worried, you said that if the neighbors are bright all night, they can not be greedy.

Electricity bill, Yang Heng's plan is to have five copper plates per bulb per month, if you pay the annual fee, it is fifty copper plates a year, and to buy a new bulb, you have to take the old bulb to exchange, this does not cost money. Why don't you install an electric meter, it's not that Yang Heng can't make it, but Yang Heng feels that making an electric meter is not very cost-effective, do you want this meter to ask for money or not, but the production cost of this is not low, at this time, it is not Yang Heng's previous life, the industry is developed.

Also, Yang Heng will directly make the light bulb into twenty-five watts, so that it will be lit for a month, and there will not be much wasted electricity, and the large power-consuming equipment, as long as Yang Heng does not make it, no one will be able to use it, and if it is not sold, who can use it, that's it.

I have to say, this steam engine is really a good thing, it can directly make the night of Chang'an City light up, and there is no power limit, even ordinary families will keep it on, but this Yang Heng is really not worried, although the steam engine is practical, but, for energy saving, you don't turn on the lights, and the consumption of the lights is about the same, naturally, Yang Heng doesn't need to care about these, this is a low-profit product, but low profits, it doesn't mean that it is low-income, isn't it, a farmer, is a light bulb, A better family will naturally have a few more, and for the wealthy family, it is a room that needs to install a few light bulbs, a family, or will install hundreds of light bulbs, you say that the total profit is high or low.

Even, it is 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, maybe the railway will be a cooperation project between the Yang family and the royal family, in short, Li Yuan has invested a considerable amount of money in it.
