King Qin's request to Korea could only be put on hold. Can't fix it. A lot of things need to be referenced by professional personnel. For example, the banking industry's investment report in the sector, etc. Someone needs to look into it. Moreover, the more Qin's economy developed, the more obvious the trend of this socialized division of labor became, and the stronger the professional and technical nature. The huge gap brought about by that kind of technology makes the general managers of this society feel at a loss.

Now this feeling has given Meng Yi and King Qin a taste. I had no choice but to entrust a third party to conduct the appraisal of the investment report. After this report is verified, the Qin State can negotiate. This is also the reason why Shang Wen feels more and more powerless. It is also an important reason why a think tank should be set up to resemble a think tank. It's getting more and more technical. At this time, one person's capacity can no longer fit so many things. For example, the Qin State gave birth to many professions that did not exist before, such as electricians, engineers, editors, journalists, typesetters, investors, and so on. Qin did not keep detailed statistics, but these industries did exist and played a huge role.

Shang Wen couldn't take care of this, he was like a fish in water in the research laboratory of Qinguo University. Research experiments are being done everywhere, and on average, more than 200 technology patents are born here every day, and these technology patents are quickly snapped up like supermarket items by small and medium-sized companies or investment bankers. Everyone knows the tremendous revolutionary results of new technologies.

For example, there have been a lot of innovations in electrical appliances that have been born here. Electric machine tools, this set of equipment is driven by all kinds of electric motors, electricity comes from coal, or all kinds of fuel, as long as it can make your boiler generate electricity, and burn all that damn cow dung. And after the modification of the electric machine tool equipment. It can be used in a variety of ways.

For example, a bottle filler. The machine can fill 50,000 bottles of milk in a single working day. This also directly drove the whole Xianyang to start drinking milk. The milkmen are from Zhao or South Korea, and they can put them in as long as they see the user's box. The bottles are then recycled.

Not only can milk be filled, but also others, a mixed drink of milk and tea is also one, as well as a variety of fruit juices, and the demand for beverages in the Qin State is huge. Even the same is true of water, and mountain springs from the Qinling Mountains have begun to be sold as a drink. If you put it in the past, people thought it was a bit unreasonable. That's what Cho and Koreans think. The Qin people were so crazy that they actually paid for a bottle of mountain spring water. unimaginable.

Not only filling machines, but also textile machines and sewing machines in the Qin State began to be driven by electricity on a large scale. This also led to the emergence of various power plant frenzyes. In the laboratory, there are more and more experiments on electricity.

People found electricity to be versatile. At this time, people finally realized the meaning of resistance, and it appeared according to different resistances. Electricity can emit light and generate heat, and although light only exists for a moment, it would be wonderful to keep this moment for a long time. This is the idea of the electric light.

In addition to electric lights, there are also various electromagnetic induction products. The microphone and amplification equipment made Shangwen very happy, so that when he publicized it in the future, he didn't have to open his throat and shout loudly.

There are also people in the laboratory who are studying early headphones, and the emergence of such devices will greatly solve many voice transmission problems. However, a lot of work has been put into the film. However, the paper industry provided a variety of papers, and the paper industry in the Qin state, after using a large number of chemicals and new paper machines, was able to produce a variety of different types of paper, including specialty paper.

Specialty paper is specially used in special industries, mainly photography, voice transmission, etc. A kind of carbon fiber bamboo paper from Bashu made of carbonization of bamboo seedlings and fusion with other bamboo materials provides a good material for it. This kind of paper has a certain elasticity after stretching, remember that it is only a certain amplitude of elasticity, that is, when the amplitude of the speech is too large, that is, the amplitude of the vibration exceeds this elasticity, the membrane will burst. This is also the reason why the research on headphones continues. One needs to find a more suitable material to compensate for this shortcoming.

There were many inventions of electricity in the Qin state. It is mainly a wide range of applications for electric motors, for example, inside the gantry crane, which drives the motor to push the hydraulic piston to complete large lifting equipment or a winch. Because, in the north, the thickness of the steel plate can no longer be completed by manpower, and the demand for a large lifting equipment stimulates the emergence of such equipment.

Shang Wen hadn't seen enough before he saw two researchers arguing violently.

"I think the use of direct current is widespread enough." A young researcher vehemently argued.

"Oh. Come on, DC, look at the poor voltage. How big something can be driven. Only alternating current works. A middle-aged man said defensively. He was a halfway monk electrician, and experience was his main achievement. There are many failures though. That's why people are working against him, because he failed.

"What are they arguing about?" Shang Wen asked an onlooker.

"Direct current, and alternating current." The onlookers looked at the two and shook their heads and said.

Shang Wen listened for a while and finally understood. It turns out that this is a confrontation between alternating current and direct current. Historically, there has been such a confrontation in electricity. As for whether direct current is widely used or alternating current, there was a period of time in history that it was simply irreconcilable. Several meetings have not been able to resolve the issue.

Direct current is the electricity we usually use, and its voltage value is small. But it is enough to threaten the safety of human life. It can drive large motor equipment, and the alternating current is mainly high-voltage electricity. It is able to pass through high-voltage lines with very low losses to reduce the loss of electricity. Obviously, the two are studying in different directions. However, what surprised Shang Wen was that the middle-aged man turned out to be the discoverer of the arc. Arc, to put it bluntly, is the phenomenon of electric sparks that we usually see, which is a kind of arc.

He suggested using a higher voltage to make a large arc and controlling it with some specialized equipment, because the arc can produce a high temperature. This high temperature can control its temperature under the control of the device. This was one of his conjectures.

He kept promoting this conjecture in an attempt to help, but the difference between alternating current and direct current slowed his research. Shang Wen is helpless, and electricity is also divided into factions.
