On the first day of the first lunar month in 1145 AD, Emperor Ming officially changed the Yuan Dynasty.
Starting from this year, the Yellow Emperor's year will be added to official documents, historians' notes, and educational institutions. According to the calculations of the Heavenly Stems and Earthly Branches, "Emperor's Century", and "Huangji Jingshi", this year is "Yellow Emperor 3842".
At the same time, Emperor Zhu changed the name of "Shenfu" to "the first year of Shenfu".
It was also determined by the ancestral precept that the future emperors of the Ming Dynasty would have only one reign name in their lives, which would be convenient for official and private use.
The traditional jade seal called the Divine Talisman has been made. This thing is not used for sealing. It is only used at large-scale events. And it is not convenient to use for sealing. It weighs nine kilograms and nine taels.
The main body of the jade seal is made of a whole piece of Hetian jade, and the raw material comes from the Gaochang area.
There is a colorful dragon lying on it. The dragon's body is smelted from various metals, and its scales are all cut and inlaid with gemstones. Two East beads are dragon eyes, and one South Sea gold bead is a dragon bead. Various materials come from all over the country, and some even come from
Dali and Tubo.
The main material of the wooden box used to hold the jade seal is Annam red sandalwood.
The jade seal is engraved with eight large Chinese characters in insect and bird seals: "Accept the heaven and serve the people, and you will live forever and prosper."
After many years, the Ming Emperor once again held the Suburban Sacrifice, mainly to tell the world and the sages that the Ming Dynasty had rebuilt the imperial seal and established the Yellow Emperor Era.
In April, the additional construction of Luoyang City was completed.
By the way, the water conservancy system inside and outside the city has been renovated to make it more convenient for citizens to use water for daily life, and river embankments have been strengthened to prevent frequent waterlogging.
While improving the water conservancy system, we also took the opportunity to build a small hydroelectric power station.
DC generator, with a power of about 10 kilowatts, is equivalent to a medium-power household diesel generator.
Don’t feel too shabby, in another time and space, the world’s first hydroelectric generator only had a power of 4.5 kilowatts.
On the day of the launch, Ju Ming invited civil and military officials and students from the capital to watch the ceremony.
The Emperor didn't come.
In fact, there is already a hydroelectric generator in Wangchuan Valley, with a power of less than 5 kilowatts, and has been running for half a year. It was a prototype that Zhu Guoxiang made through repeated experiments. After the test was successful, it was copied to Luoyang and the power was increased.
Unfortunately, the invention of the electric light failed!
To be precise, it is half the battle. The carbon filament light bulb was successful. It was made entirely by hand and inert gas was added, but the service life of this thing is too short.
Zhu Guoxiang certainly knows how to use tungsten wire. The question is how to purify tungsten?
The most difficult thing now is not the purification method, but that we don’t know what tungsten ore looks like and what kind of mineral it can be extracted from.
In fact, it is very simple to purify platinum, and it can also be used to make filament.
But the question remains, what does a platinum mine look like, and where should I find it?
In today's Ming Dynasty, the development of science and technology is abnormal, and chemistry seriously lags behind physics. The subject of chemistry requires countless scientists to slowly discover, experiment and accumulate.
The hydroelectric power station was built on the southwest side of the imperial city, where there is a water trough for the imperial city.
The sedimentation tank is equivalent to the sedimentation tank of the waterworks. China has existed as early as the Eastern Zhou Dynasty. At the Yangcheng site of the Eastern Zhou Dynasty, not only sedimentation tanks but also ceramic underground water supply pipes were found.
This sedimentation tank on the southwest side of Luoyang Imperial City mainly provides drinking water (including washing) for the palace maids and eunuchs. As for the royal family members and officials in the imperial city, they naturally drink the well water in the palace. The main purpose of this is
Prevent poisoning.
After Luoyang's water conservancy was improved last year, a total of 24 sedimentation tanks were built inside and outside the city, and a large number of new ceramic underground water supply pipes were laid.
Urban water safety has been a top priority since ancient times.
For example, during the Xiaozong period of the Southern Song Dynasty, the largest water supply source in Hangzhou was the West Lake, but people often dumped feces and garbage. In order to rectify the matter, the court directly targeted two ministers and dismissed them from office for washing horses in the West Lake and polluting the water source.
However, it was said that Zhu Guoxiang sent people to build a two-level water tower next to the sedimentation tank in the imperial city. It was not an iron tank, but more like two oversized reservoirs.
It is not very high either, the first level water tower is fifteen meters, and the second level water tower is less than five meters.
The generator is installed between the two-stage water towers, with a height difference of about ten meters. At this height, only about 0.06 cubic meters/second of water is needed to provide kinetic energy for a 10-kilowatt generator.
The original method of delivering water to the water tower was very primitive. The eunuchs used human hands to press the water pump and pump it up bit by bit.
More than a dozen eunuchs took turns to shake it for seven days and nights. In order to speed up the progress, they even used pulleys and buckets to lift it up one by one.
At this moment, the first-level water tower has opened its gate, driving the generator to do work.
The water that flows down falls into the secondary water tower, providing a water source for the newly laid water pipes in the Imperial City - mainly used for washing items. For example, officials can wash their hands by turning on the faucet, but if someone wants to drink water directly,
OK.
All civil and military officials, as well as students from Imperial College and Imperial College, were all watching intently at this moment.
"Your Majesty, you can turn on the electric water pump."
"Open it."
The more than ten-meter-high water pipe that carries water to the water tower is made of copper.
One of Zhu Guoxiang's students has already become a magician in the Ministry of Industry. Now the magician and several staff members connected the water pump to the copper water pipe, and then pushed up the switch.
The sound of "buzzing" sounded, and the official on the water tower quickly shouted: "The water is coming, the water is coming!"
The officials and students were stunned.
The cabinet minister Fang Mengqing died of illness last year. He died of a serious illness while in office. Currently, Huan Guo is replaced as cabinet minister. Pan Lianggui was transferred to the Ministry of Personnel and Wei Liangchen was transferred to the Ministry of Household Affairs.
Huan Guo was shocked and inexplicable: "I have long heard that the Supreme Emperor has the ability to control electricity. This is so magical and unpredictable!"
The Taipei student representatives were mentally prepared. Some of them had been playing with electric stacks (original batteries) for nearly two years.
For Ju Ming and Zhu Guoxiang, this is just a small fight.
Moreover, the water tower generates electricity and then drives the water pump to lift water. It is impossible to move forever. At critical times, manpower must be used to shake the water up.
But this is a good start, and it is convenient for life in the imperial city.
Under the water tower, tap water pipes are laid. They are all wrought iron pipes, with the outer layer painted to prevent rust, and the interfaces are cold welded with zinc-tin alloy (traditional cold welding uses lead-tin alloy).
Zhu Ming walked towards the faucet with a smile: "Everyone, please take a look."
A eunuch brought some fragrant soap, Ju Ming turned on the faucet, water flowed out, and the emperor began to wash his hands with soap.
Everyone likes it very much. This thing is so convenient.
Ju Ming asked: "Does anyone know how this tap water works?"
The Tai students were eager to answer, and one of them bowed first: "Reporting to the official, this is due to the effect of water pressure. The second-level water tower is more than ten feet above the ground, and water will gush out of the water pipes on the ground."
"Good at physics," Zhu Ming asked with a smile, "What's your name?"
The Taixue student happily replied: "The student's name is Li Yue, and his courtesy name is Duzhi. He is now the Imperial College student who sacrifices his life."
Ju Ming nodded slowly.
Although it was just a verbal praise, it made other Tai students envious.
Ju Ming said to the officials: "The government officials working in the imperial city can use this tap water in the future. Water pipes have been laid in the harem and various palaces. If there is a fire, water can be quickly released from the water pipes. Remember not to waste it. Water is stored in the water tower.
Water is limited and electricity pumping is not enough, and manpower has to be used to lift water every once in a while.”
"I obey!" Senior officials bowed quickly.
Zhu Ming smiled and said, "Let's call it a day. Let's go back and try."
Everyone resigned.
Officials working in the imperial city returned to their respective offices.
Construction has been going on for the past two months, and they know where the faucets will be installed.
Over at the Privy Council, Li Bao turned on the faucet, put it in his mouth and drank directly. He said with a smile: "It's like spring water gushing out in the mountains."
"You don't mind being dirty either." Yang Zhi expressed his disgust.
"The water that has passed through the sedimentation tank (sedimentation tank), no matter how dirty it is, can't be any more dirty." Li Bao stepped away after washing his hands. "You guys should try it too."
After a while, an official from the Ministry of Works came over and said, "Generals, you can go to the toilet and take a look."
Wang Yuan asked: "You have been tinkering with the toilet for a month. We all have to use buckets when going to the toilet. What has happened?"
A group of generals curiously ran to the Privy Council hut, only to see a row of squat toilets there.
If foreigners see it, their eyes will probably turn red.
The pooping thing is actually made of ceramics!
The official pressed the toilet button and water flowed into the squat toilet.
The generals all understood and praised this method. With the incense burned in the toilet, there was no smell at all - in ancient high-end toilets, incense was burned every day to drive away odors.
Officials used squatting toilets, but Ju Ming himself used sitting toilets.
At this moment, he sat on the toilet and enjoyed it for a while. After flushing, he returned to Chui Gong Hall to approve the memorial.
This feeling is so refreshing. The toilet is filled with toilet paper, and it feels like experiencing modern life again.
One or two more water towers need to be built. After all, the imperial city is too big and the tap water will be empty as soon as it is used. The generator may not be able to cope with it.
Moreover, if you build a water tower, you can also add a generator to drive an electric fan or something.
In the offices of emperors and officials, installing such ceiling fans does not use much electricity, but it is very refreshing in summer.
If you want to generate electricity continuously, you have to build dams.
Unfortunately, with current technology, the loss rate of long-distance power transmission is too high, so a small dam must be built nearby.
Ju Ming is sending people to Xuzhou to select a site, which is the largest iron smelting base in the country. If a hydroelectric power station is built in Xuzhou, it will have electricity, coal, and iron ore, and its development will surely make rapid progress.
Ju Ming muttered: "According to European calculations, it should be the Middle Ages. The Middle Ages with hydropower stations, it's fucking outrageous to think about it!"
Cabinet, hut.
Several cabinet ministers were playing with the toilet bowl. No one wanted to persuade the emperor not to lose his ambition by playing with things, and no one tried to persuade the emperor not to carry out large-scale construction projects.
They like running water and flush toilets very much.
There could be more of this kind of playthings and large-scale construction projects!
Li Hanzhang even asked without a teacher: "Can we intercept the Yishui River and build a dam at Yique Gate to continuously drive the generator? Then build a few water towers and lay water pipes throughout the city so that all the people can
Do you have access to running water and flush toilets?”
The ministers were stunned when they heard this.
It seems... ok.
Ling Guxu thought about it and said: "The terrain must be carefully explored. It cannot affect the people upstream and downstream, nor can it affect the navigation of Yishui."
Huan Guo said jokingly: "Dragon Gate is also there, just a little downstream of Yique Gate. We will intercept the water there and build weirs to generate electricity. I am afraid that many failed scholars will scold their mothers because the imperial court influenced them to jump over Long Gate."
"Hahahaha!" Everyone laughed when they heard this.
