Although it is a generator, Jiang Wei's is a small hydroelectric generator, the voltage is not high, and it is only suitable for experiments, but in order to make this thing, it also took a lot of effort, mainly because it is more troublesome to build this part.

Fortunately, Jiang Wei has a good uncle, and the parts are all made one by one by these top craftsmen in the Ministry of Industry, and finally brought back to assemble.

In the previous fairy exhibition, the sodium used for water ignition was extracted by electrolyzing sodium carbonate solution (soda ash water) with this generator.

And there is an electric light bulb on the generator, which Jiang Wei currently has no way to produce in large quantities, and the most critical factor is tungsten. Don't underestimate tungsten, if it weren't for the appearance of Jiang Wei, this era would not have been born at all. Even magma is just over 1,300 degrees.

The melting point of tungsten is more than 3400 degrees, what is the concept? The charcoal is only about 700 degrees, and the maximum temperature of coke is only 2500 degrees, no matter how to use some means, the coke cannot reach 3,000 degrees.

So 3000 degrees is a technical watershed, and under the current conditions, as far as Jiang Wei knows, only the mixing of natural gas and rare earth fuels can reach 3400. Natural gas Jiang Wei has already obtained, coal seams and coking carbon are produced, but rare earths are very difficult to find.

Therefore, Jiang Wei could only choose to make his own chemical fuel, acetylene, molecular formula C2H2, commonly known as wind coal and calcium carbide gas.

To obtain acetylene, you must first obtain potassium carbonate.

Jiang Wei adopts the Lu Bran method, which is to mix potassium sulfate (potassium sulfate Jiang Wei obtained from coarse salt) with pulverized coal and lime, reduce and roast to obtain black ash (containing potassium carbonate, calcium sulfide and other sintered products), which is leached, filtered, evaporated and carbonized to obtain potassium bicarbonate, and then filtered and finally calcined to obtain potassium carbonate.

Charcoal and potassium carbonate are then heated to produce metallic potassium, and the residue (potassium carbide) is thrown into the water to produce a gas called acetylene.

Tungsten filament, on the other hand, is made by melting tungsten ore with acetylene, then extracting ferrotungsten, and finally making tungsten filament.

In the previous life, it was not so troublesome to obtain ferrotungsten, at that time, it was directly used as an electric furnace, a solar furnace. However, there is no technology now, in order to obtain tungsten filament, Jiang Wei also spent a lot of effort, and also understood how difficult it is to start chemistry from scratch.

But all this Chen Shuozhen and Xu Huiruoniang are not clear.

And because it is a hydroelectric generator, Jiang Wei usually needs to run a long distance to do electrolysis experiments. At this point, it's just a light bulb, and just turning it by hand is enough to supply the light bulb.

The moment the light bulb turned on, it was a miracle, and in Chen Shuozhen's eyes, there was no doubt that it was a miracle.

Chen Shuozhen looked at the shiny light bulb obsessively, and really couldn't understand why there was no fire, and this thing would shine. And her appearance fell in Xu Hui's eyes, and her little melon seed face was full of pride, as if she had made it herself.

"The second question, my request is very simple, you don't need to know what its principle is, you just need to observe it, even take it apart, tell me what you find, and your feelings."

Chen Shuozhen glanced up at Jiang Wei, and his expression became more respectful,

"Immortal Master, can the little girl live here? Staying in the grocery room is fine. The little woman had run out of money. ”

Chen Shuo is really honest, Jiang Weigao glanced at her, and nodded,

"Cousin, let's see where there is a room available, and arrange a room for her."

Xu Hui pouted, a little unhappy, but still agreed.

"Come with me."

After Xu Hui and Chen Shuozhen left, Ruoniang also left with Xu Hui. Jiang Wei sat there and thought about it, the name Chen Shuozhen, I don't know why it is a little familiar, it seems that I have heard it somewhere, or where I have seen it, but I can't remember it for a while.

However, Jiang Wei didn't care too much, he still had a lot of things to deal with, the first thing was the joint meeting of the seven shopping malls.

Jiang Wei came to the place where the meeting had been held, the Jingxuan Pavilion under the name of the eldest grandson, and at this time, the representatives of the seven families, except for Xiaoxian, the head of the Yu family, and Song Bingcheng, the head of the Song family, the representatives of the other five powerful families were still in charge of foreign affairs.

As usual, the first thing to do was for the Yu family and the Song family to report on the progress of the project and the cost of material purchases.

"At present, the commercial plaza is halfway through, and the construction is currently on the second floor, and in this week, the number of injured people is seven, and the death toll is two. Most of them are caused by falling bricks. ”

Hearing the report of the Song family, the head of foreign affairs of the Xiao family, who was in charge of finance, was not very happy.

"The Cheng family is responsible for safety, so there is no way to solve the problem of injuries to workers, 23 people have been injured and seven have died this month, and the money has to come out of the finance department? If you want me to say, since the Cheng family has accepted the security problem, then if something goes wrong, the Cheng family should be responsible. ”

The head of foreign affairs of the Cheng family was not happy.

So the meeting turned into an argument and a quarrel began. The quarrel was in the back, and even the anger was raised. Jiang Wei frowned and had to speak,

"Representatives of the Cheng family and representatives of the Xiao family, listen to me."

Jiang Wei's words were quite effective, and the two foreign affairs directors listened to it, but they also quieted down, but their faces were still not good-looking.

"As for compensation, it's a trifle. Workers are constantly injured, which is a big deal. As for the financial aspect, compensation will be given first. At the same time, I hope that seven days later, the Cheng family can come up with a solution, at least a way to reduce casualties, if there is no better plan, starting next week, the Cheng family will be responsible for half of the compensation for injuries and deaths, what do you think? ”

After everyone listened, they nodded with satisfaction, the compensation for the death of one person is thirty times, and the injuries are even more, and they must be responsible for all the medical expenses, which Jiang Wei first proposed and approved by everyone, but they did not expect that the casualties would be so big.

This financial money is paid by everyone, and of course other families will be dissatisfied. Hearing Jiang Wei's plan, he could only say that he reluctantly agreed.

The head of foreign affairs of the Cheng family did not object for the time being, but said that this matter needs to be reported first and then discussed.

Then he said that he reported the purchase of materials and the money spent at home.

Then comes the financial reporting of the total financial expenditure.

When the meeting came to an end, the head of foreign affairs of the Yuan family stood up.

"Jiang Gongzi, my Yuan family has always admired Jiang Gongzi's talent and personality, but there is one thing, Jiang Gongzi is not authentic."

Jiang Wei glanced at the foreign affairs director of the Yuan family suspiciously,

"The representative of the Yuan family has something to say."

The head of foreign affairs of the Yuan family smiled,

"Jiang Gongzi, then please forgive Yuan's bluntness. At the press conference of the commercial plaza on the same day, Jiang Gongzi bluntly said that he would invest in glass technology, but why has he not passed on the mirror technology to me? ”
