The early spring sunshine shines gently on the Jianghuai land, and this piece of land southeast of Chaohu exudes a vibrant atmosphere. It is another spring plowing year. Due to the guarantee of water conservancy projects and the good sunshine conditions on both sides of the Yangtze River, the farmers here fully demonstrate the virtue of hard work, which is the core of the Chinese. Because farmers take the big heads in the harvest of grain, each farmer commune actively arranges the work of this group. The work of the agricultural group is only to inform advanced production experience and coordinate the maintenance and use of water conservancy by each group.

Cheng Pan now implements a policy of letting go of agriculture in the territory because the improvement of agricultural productivity is no longer needed to promote it. Now the administrative group cannot generate profits from farmers and basically maintains a balance of income and expenditure. In other words, very few part of the grain in the public granaries in the territory is collected from the land tax, and the increase in grain output has no direct impact on the increase in tax revenue in the territory. However, Cheng Pan knows that farmers are now a huge market. How did the commercial development in Jiangsu and Zhejiang come from in ancient times?

It is not that they are smart but that their agriculture is developed. Agriculture creates more wealth than the local consumption of agricultural wealth. The remaining wealth is accumulated among the people, and the people have purchasing power to form a market. Cheng Pan opened up the development of other industries, the sales of iron utensils are gradually increasing, the scale of brick and tile kilns is gradually expanding, and a large number of communes purchase construction materials and build collective housing. The essence of the small peasant economy is not the conservatism of farmers, but that farmers really have no money in their hands. The industry nurtured by agriculture is growing.

Business is now like a spoon. Industry uses it to scoop up the nutrients in agriculture to supplement itself. Eating in a bowl and watching the pot is a good habit. The industry created by Cheng Pan is no longer satisfied with its own market in the three-part fields. The output of industrial products is necessary. Looking at what was the money-making industry in the early days of the growth of industrial countries in the world? That's right, the textile industry. Channels are excavated on the north bank of the Yangtze River, and giant water wheels are established. The initial historic innovation of the Western textile industry was Jenny spinning machine. This thing has a low technical content, which is the use of shuttle technology. This thing was quickly conquered with the cooperation of several carpenters and weaving experts. In the water turbine

Driven by the way, there is no need to consider the limiting factor of human strength. At the same time, steel, a high-strength material, replaced wood, became a component in the machine. The internal stress strength of the entire loom is enhanced, so the scale is large. The time-consuming and hard-working craft of weaving is replaced by a machine combining iron and wood. The price of cloth in the entire territory dropped sharply, and merchants traveling to and from the territory purchased a large amount of cloth from the territory. Since the group of weaving households had not been formed in Chengpan's territory before, the birth of this industry did not seize any interests, but the cloth merchants in the lower reaches of the Yangtze River will be impacted, but they cannot incite weaving households to come and smash the machines. In the process of industrialization, a group of people will always be crushed.

As the steel production in steel plants becomes larger and larger, Cheng Pan feels that it is impossible to consume so much steel by relying solely on the current human and animal agriculture and hydraulic industries, and new types of power must be found.

Cheng Pan aimed at the steam engine technology. It has to be said that this technological leap forward was a complete failure. The principle of mechanical and mechanical structure was a simple problem. The prototype was quickly created. Cheng Pan watched the thing run, lit it, and could move it, but the air was everywhere. The sound and momentum were comparable to ten pressure cookers, but the output power was too low. An adult could stop the movement of the machinery with his hands, hoping that it would replace the hydraulic machine and waste coal. The people in the experimental group did it quickly.

This time, they did not use Willow Ding as a link, but instead used tin lead metal juice to weld the gap. This dangerous work was done by Cheng Pan, and the force of the sun was indispensable. Cheng Pan used the unique human energy welding method in the world. Finally, the prototype ran again, and there was less air leakage in other places, but the piston part was still impossible. Modern industry uses vulcanized rubber in pistons, and the rubber tree is still in the primeval forest of America. With current navigation technology,

Rubber is nothing to think about. Without rubber, Cheng Pan wants to use substitutes, leather becomes a test product. The craftsman has good skills, the machine is running normally, and the air leakage is completely stopped. The steel torque of the steam engine becomes stronger with the rotation of the iron wheel, and the steam engine completely looks like a steam engine. Before everyone cheers for a long time, the collapse sounded muffled, and the sound sounded the same as the sound of a popcorn furnace on the street. The piston of the steam engine sprayed out some waste leather slag. Then there was a thundering sound.

Ming leather is not rubber-resistant, so if it is replaced by Cheng Pan's leather, it is almost the same. Unfortunately, Cheng Pan does not have the fearless spirit of dedicating himself to science. Leather is not good, so let's change to something else. More than a dozen reliable materials are replaced. The best material is just a kind of cork, which is the kind of cork that is now plugged in thermos. This kind of cork can only last for half an hour, and then it will be ground into wood chips. The first time the steam engine was developed failed, I could only wait for the metal processing technology in the territory to further improve and reduce the gaps in the piston.

After the failure of the steam engine manufacturing, Cheng Pan set his research direction on another aspect. As a modern person, he is no stranger to electricity. The principle of generators is mainly to cut magnetic induction lines and left-hand rules. In history, the emergence of generators later than steam engines was mainly stuck in the principle of electricity. Cheng Pan, who was tempered by the college entrance examination system, was not ashamed to pass on the achievements of the electromagnetic giant to people in this time and space. Of course, the excuse was still to be ordered by heaven. Many craftsmen and students in the territory did not doubt it. After all, thunder was a sacred existence in the cognition of the ancients. However, with the advancement of science and technology, after Cheng Pan left this plane, the origin of electromagnetics became an academic pit of the original plane. However, the initial application of electromechanics was very unsuccessful.

The principle of generator is indeed very simple, and the technical requirements are not high, but the process is difficult. First of all, the first pit is the search for magnets. There are few natural magnets in nature, and generators require magnets to form a magnetic field. Modern magnets are manufactured in industrial fields. Cheng Pan did not pay attention to this point and was very confused at first. Later, a doctor provided a method for making permanent magnets. This method was taken from the first volume of "Wu Jing Zongyao" compiled by Zeng Gongliang during the reign of Renzong of the Northern Song Dynasty. It is to burn iron sheets and place them in the north and south directions, then quench them, and use

The earth's magnetic field was magnetized. For Cheng Pan, the earth's magnetic field was weak, so Cheng Pan first used a natural magnet to make a generator, and then made a magnetic coil with silver wire. After generating electricity, a strong magnetic field was generated in the magnetic coil, and then the red iron rod was inserted into the magnetic coil to quench it. The effect of magnetism on the artificial magnetic field was amazing. In this way, Cheng Pan accumulated a small amount of magnets into a large number of magnets. Then it became convenient. Cheng Pan took people to cut a small river and created a dam, used a water conservancy drive water wheel to cut the magnetic induction wire, and electricity was transmitted from the copper wire wrapped in lacquer cloth. A new energy was born.

But the embarrassing moment has come, and the electricity is made but cannot be used. First of all, the electricity is made of hydraulic power, and the electricity cannot be transmitted too far. Although the AC power is made, the voltage is too low and the transmission loss is too large. Cheng Pan has not tried the transformer. The principle of the transformer is very simple, which is the magnetic coil with a small number of turns corresponding to the magnetic coil with a large number of turns. After the product copied from high school physics books is used, the voltage rises, but the current drops too much, and the motor rotates weakly. Then a burnt smell, the enameled silver wire burns, and then a spark of electric sparks, and the copycat goods are scrapped. The power cannot be transmitted far, Cheng Pan thinks it is better to use a water conservancy machine directly. It costs so much silver wires and copper wires can only be transmitted for dozens of meters, which is too unscathed. Anyway, there are still many open spaces by the river.

In the end, the generator set was still retained, and the chemistry laboratory accepted it. It was changed to a DC generator. The electrolytic experiment was performed. The yield of refined copper increased sharply. Chlorine and pure hydrogen were also generated. However, the electrolytic reaction tank did not continue to expand. As a raw material for chlorine, salt could not keep up with the consumption. Originally, Cheng Pan transported a large amount of salt from the beach and edible in the territory was enough, but it could not support the consumption of industrial production. As for purchases, the low salt production efficiency in this era could not be reduced.

Fortunately, not only did the chemical group need electricity, but electric tin soldering became a major power consumption. Many generator sets were built around him. Cheng Pan thought about it but could not give up the temptation of the steam engine. Cheng Pan set up a group to weld the steam engine with tin soldering, and processed corks in large quantities, using corks as a consumable. The new steam engine could easily replace wooden pistons. So in this era of such backward materials, the steam engines entered the era.
