On the same day, Liu Zhi asked the craftsmen and painters to work together to draw the drawings of the wheelbarrow and the pulley, and he was worried that he would not be able to remember the details, so he instructed to make samples quickly.

If there is any problem, it can be solved in time.

Dong Ban plunged into the Ministry of Works, and together with a group of civil engineering masters and other professionals in flood control, discussed and studied the structure of the sluice gate.

Liu Zhi also racked his brains and began to recall that there were simple instruments that could be used now.

The representative works of the first industrial revolution period are the invention of the steam engine and the Jenny loom, and to be honest, he knows nothing.

I still know a little bit about the principle of the steam engine, and I have seen simple steam experimental equipment, which can be drawn and left to the craftsmen to tinker with.

No matter how many years it takes, it's always one direction.

As for the textile machine, I have only vaguely seen the pictures in the book, and I really don't know anything about it.

The most epoch-making invention of mankind, in the hearts of ordinary people, is definitely the generator, and that is really often seen.

When I was a child, the electricity in the countryside was unstable, and many families had such a thing in case of emergency.

This thing is easy to break, and his grandfather often repairs it manually, and he basically does it by his side.

Therefore, we know a lot about its structure, but when it comes to power generation, we must not bypass the extraction of oil.

Without diesel or gasoline as fuel, the generator would not work at all.

Thinking of the serious pollution caused by plastics in later generations, he has always been a little hesitant, and the concepts and ideologies of ancient people cannot keep up.

It is difficult to say whether the premature appearance of oil will bring convenience or disaster, but after thinking about it again and again, it has been decided to put this project down for the time being, and wait for the situation to see the situation later.

When it comes to electricity, he suddenly thinks of something similar, biogas.

In rural China, it was advocated for a while to build a biogas digester from waste materials such as human and animal manure, which could be used for lighting, burning and cooking, and even large biogas power plants.

Once, his grandfather's house built one under the call, Liu Zhi was very interested at the time, and he participated in and watched the whole process of construction.

If you think about it, you can still recall most of it.

Biogas is a clean, renewable energy source that does not pollute the environment, improves the quality of life, and can be used for industrial development.

The more Liu Zhi thought about it, the more excited he became, he always complained that life in ancient times was inconvenient, the black lights were blind, and cooking was smoky.

The most inconvenient thing for him is the bad smell, don't look at the ancient streets on TV, they are all antique and beautiful.

But you only need to walk around in the summer to ensure that all kinds of smells and smells make you dizzy.

Even if he built a new town on the other side of the alley, all of which had sewers and drains, it would not stop the wonderful smell of the septic tank.

Even in the palace, except for a few main palace rooms that are cleaned by special personnel at all times, the rest of the smell is probably not so fragrant.

But once the digester is built, everything can be changed. After closed fermentation, the digester does not emit any unpleasant odors.

Wealthy families can afford to build their own biogas digesters, and poor families can also build several families together, and places such as cattle and horse farms can even store biogas for sale.

The biogas residue in the city can be collected and transported outside the city to be used as fertilizer.

Biogas residue has high fertility and no bacteria and insect eggs, which is a good fertilizer with high quality and high efficiency.

It was even more convenient for the farmers in the suburbs, who lived together for generations, and basically raised chickens, ducks, pigs and sheep and other livestock.

Therefore, if the raw materials are sufficient, if it is not enough, you can also add some kitchen waste, domestic wastewater, and even chopped straw and grass for mixing.

Liu Zhi almost didn't sleep all night, his spirit was very excited, he drew sketches while recalling, and kept revising and revising according to his memories.

Finally, the basic drawings were completed, and the detailed construction process was written down by Bala.

The biogas digester is easy to repair, but it is troublesome to use, and the folk describe it as three points of cultivation and seven points of maintenance.

Careful maintenance in use is very important, and you can't be lazy at all, for example, you should often uncover and stir on weekdays to make the fermentation even.

The biogas storage tank and biogas transfer pipe should also be cleaned frequently to avoid blockages.

The pond also needs to be cleaned up frequently, and for modern people, there are more convenient alternatives to electricity and natural gas.

Therefore, many people have built biogas digesters, but they are too lazy to maintain them, so that in the end they become decorations.

However, Liu Zhi believes that this was not a problem in ancient times, as long as the technology was mature, it was completely possible to use the regulations in clear text.

By the way, cement is needed to build a biogas digester to achieve a sealing effect, and I don't know how the cement has been developed.

More than half a year has passed, so there must be results.

Regardless of the fatigue of a sleepless night, Liu Zhi hurriedly summoned the leader of the craftsmen in charge of the matter.

When I asked, I found out that two or three versions had been developed, but the craftsmen themselves were always dissatisfied, so they didn't dare to present them.

Liu Zhi was also puzzled when he heard this, what did he come up with, so he planned to take a look in person.

The location of cement research and development is in the suburbs, Liu Zhi and his party traveled lightly, secretly traveled, and when they arrived at the place, they saw that they were good guys, and the raw materials everywhere were piled up like mountains.

Looking at the piles of lime and ash, gypsum, kiln slag and the like, Liu Zhi magically had a familiar sense of intimacy.

If it weren't for the workers coming and going in ancient costumes, it would have the feel of a modern small factory.

The foreman in charge of this in the Ministry of Industry is called Ruan Qi, a person who strives for perfection, and under his demonstration, Liu Zhi visited the three versions of cement.

Just looking at the appearance, these three kinds of cement are quite similar to that, Ruan Qi personally demonstrated, mixed three batches of cement with the same proportion of fine sand, and then smeared three cement floors.

Half an hour later, Liu Zhi took a look and found that although the three batches of cement had not been completely solidified, the degree was different.

The first batch is still relatively thin, and if you poke it with a stick, you can easily poke a hole, which is obviously unqualified.

Compared with the second batch, it was overkill, obviously too hard, and there were already signs of cracking before it solidified, and it was not good.

The third batch of Liu Zhi feels okay, the solidification is almost complete, and the hardness is also good, you must know that it is now winter, and it is understandable that it is slow to solidify.

Even now, ordinary cement is like this, the only defect is that it is rougher than modern cement.

This is limited by the crushing technology, no wonder he is already fully usable.

"The third batch of cement, if there is any hardened ground, take me to see."

In such cold weather, he didn't have time to wait here for it to solidify completely, only to see the finished product.

Ruan Qi hurriedly brought Liu Zhi over, where a piece of ground had been laid with cement and a house had been built with sand and ash.

Liu Zhi checked it carefully, fortunately, there was no cracking, but they didn't know how to collect the light, so the ground looked rough and not delicate and smooth enough.

A repaired house is much stronger than a lime and sand alone.

Ruan Qi said regretfully, "I'm ashamed, this wall is much worse than the glutinous rice juice." ”

Liu Zhi was speechless for a while, everyone knows that the wall of pouring glutinous rice juice is unbreakable, the key is whether you can afford it, the yield of glutinous rice is low and the price is expensive.

A section of gray city wall, in ancient times when food was scarce, its cost can be described as poor and extravagant, and even he, the emperor, could not afford it.

Or cement is cheap and practical.

"With your current technology, if you put it into production, how much can you produce per month?"

Ruan Qi should have already figured this out, and immediately answered.

"Back to Your Majesty, if you build a workshop of 200 people, it can produce about 2,000 catties a day."

He was cautious, and the quantities he said were generally conservative estimates, and the rudimentary tools of antiquity, the calcination process required to produce cement, and the final crushing process, would have been troublesome without the help of machinery.

In particular, the crushing is basically completed by manpower and sledgehammer, which seriously slows down the speed.

Liu Zhi frowned, "If it is used with water, can it increase the yield?" ”

Ruan Qi said with a smile, "Back to Your Majesty, this is a calculation of the speed of the water mill. ”

In the Eastern Han Dynasty, the development of hydraulic machinery was very rapid, and the water cylinder used to lift water, the water mill used to lift rice and crush ore, and the water drain used to drive the iron smelting blower and so on have appeared.

Liu Zhi is busy with state affairs, and has not paid much attention to these hydraulic machines, it seems that this is his omission, and the development of hydraulic resources can also promote the development of production.

At this time, the water mill was still operating with a single mill, and the conversion rate was low, and he remembered that he had seen the combo mill in the Tang and Song dynasties in the history textbook, and there could be up to four mills working at the same time.

Ability to make efficient use of water energy.

In fact, the combo is only slightly changed on the basis of clicking on the mill, and the people of the Han Dynasty are completely limited by experience and thinking, and they don't think so much.

So with a little bit of guidance, the combo can be built in no time, and it can be used for ore crushing when the time comes.

The initial success of cement research and development made Liu Zhi very pleased and ambitious, this thing is too important, can greatly improve the firmness and service life of the building.

This makes some large-scale water conservancy projects more robust and, of course, the most remarkable is for road curing.

It has made a qualitative leap in human transportation.

After going back, Liu Zhi was busy improving the water mill, and he was immersed in inventions and creations for many days, so busy that even such a big thing as the year-end official assessment was thrown to the secretary province, the Zhongshu province and the secretary department to jointly implement it.

Dong Ban's return was like a key, which opened his passion for mechanical invention, and he was busy until the end of the month, when he not only improved the water mill, but also invented the water mill, water mill and water mill by the way.

These things are mainly used in grain processing, and water mills are used to crush wheat, which is 100 times more effective than manpower or cattle and horses, and can run 24 hours a day.

Water mills can be used to remove the bran from grains, etc., and as for the reels and overturns, there were already rudimentary forms at that time, but they were not mature enough.

Liu Zhi and a group of craftsmen studied day and night, with the outline in their memory, coupled with the familiarity of modern people with gears and couplings, they finally succeeded in improving all of them, greatly improving production efficiency.

When the craftsmen had gained experience, he gave them another difficult task, that is, the construction of a water-powered loom.

During the first industrial revolution, Britain relied on a large number of water-powered looms and water-powered printing and dyeing machines to improve wool textile technology, and the economy developed rapidly, thus embarking on the road of hegemony.

He really didn't know anything about ancient looms, but the principle of water driving the machine through a chain was the same.

He believed that as long as the contours of the mind were provided, these craftsmen should be able to successfully drum up the water-powered loom.

His busyness made many courtiers in the court a little dissatisfied, thinking that the emperor did not do his job properly, and the strange skills and tricks have always been despised by the literati.

But now the emperor is fully engaged in it, almost ignoring other things, and he feels a little crazy.

For a while, some courtiers kept reminding him that he hoped that the emperor would give up the study of these strange machines and shift his mind to the government.

Many of Liu Zhi's operations in recent years have left an impression of willfulness, so this time is no exception.

He took a blind eye to the various performances that flew like snowflakes, and didn't bother to pay attention to them at all.

Anyway, I can't explain it to them, and I get tired if I talk too much, and it is precisely because of this incident that Liu Zhi began to think about whether he should add physics and chemistry subjects to the school.

The development of industry is inseparable from the basic physics and chemistry, I think he was a good student before he made friends with those gangsters, and he also served as a representative of the physics class in junior high school.

Therefore, he still remembers a lot of simple physics knowledge very clearly, and he can write the most basic physics textbook silently.

These basic theoretical things can broaden people's horizons and sow the seeds of science in the hearts of children.

In time, a group of professional physics talents may emerge in the future, which will slowly drive the industrial development of Dahan.

In the second year of Xiyuan, except for the first day of the Lunar New Year, he attended the Yuan Ri Pilgrimage, the rest of the time was closed, desperately recalling the physics and chemistry textbooks in middle school.

Due to the age, the memory has begun to be biased, so many things are a little plausible.

However, science is not a little fake, maybe for him is just some vague memory, but after being compiled into a textbook, it may cause misleading and make future generations take many detours on the road of scientific exploration.

In the end, it will take countless practices and experiences to correct these mistakes, and the cost is too great to outweigh the losses.

When this is not the case, he uses his brains more to minimize the occurrence of mistakes, and if he really can't remember something, he would rather delete it from the textbook than destroy people.

So throughout the first month, His Majesty the young Emperor, as if enchanted, stayed in the study all day long, scribbling and changing day and night.

This made Empress Dowager Yun and Empress Deng very worried, and they found an opportunity to run to persuade them twice, but Liu Zhi was perfunctory.

only said that they were thinking about national affairs, and both of them were harem women and couldn't do politics, so they could only let it go.
