Chapter 735: The Electric Lighting Used In The Dimensionality Reduction Attack, And The Hydroelectri
No manpower required!
Twelve hours a day!!
No matter when you come in, as long as you turn on the light, the room will be as bright as day!!!
Zhu Yuanzhang and all the civil and military officials could not help but breathe rapidly.
Perhaps they are far inferior to Yan Changqing in terms of knowledge and cultural level.
But when Yan Changqing reached this point, no matter how stupid they were, they clearly understood the importance and prospects of "electricity" and electric lights!
Leaving aside other aspects, at least in terms of lighting, electric lamps can be said to be a real dimensionality reduction blow to lighting tools such as candles.
Before the advent of electric lights, from the emperor to the common people, indoor lighting at night was basically done by candles or kerosene lamps.
However, the lighting range of candles and kerosene lamps is not very large. At most, a candle or a kerosene lamp can only illuminate a small area.
For example, for a three-foot desk, within this range, candles and kerosene lamps can barely meet the lighting needs.
But if placed in a large-scale environment, such as a palace, then ten candles and ten kerosene lamps would be difficult to meet the lighting needs.
For example, in the palace where Zhu Yuanzhang reviewed memorials at night, in order to meet the lighting needs in the palace, dozens of candles need to be lit for lighting, and sometimes hundreds of candles need to be lit for lighting.
And this was because Zhu Yuanzhang was frugal and was unwilling to be extravagant and wasteful. He only asked the chamberlain to light candles in the main areas where he walked and worked at night, and no candles were lit in other areas.
Otherwise, if it were another emperor, at least hundreds of candles, or even hundreds or even thousands of candles would be lit for lighting.
This is not an exaggeration. It is normal for palaces within the imperial palace to be as small as one or two hundred square meters and as large as four or five hundred square meters.
And if you want to meet the lighting needs of such a large area, it is normal to light dozens to hundreds of candles for lighting.
In addition to the small lighting range, the second disadvantage of candles and kerosene lamp lighting is that it is expensive!!!
In this era, candles and kerosene lamps were not cheap.
Most people cannot afford candles or kerosene lamps, so they basically go to bed when it gets dark.
Light up the lights?!!
Light candles?!!
Don’t think about it, you can’t afford it if you don’t have money!!!
Unless there are scholars in the family, then a kerosene lamp will be lit next to the desk in the study room for reading at night.
And if the family situation is more affluent, they will replace the kerosene lamp with a candle.
Of course, if the family situation is richer, then the number of candles will ultimately be proportional to the family situation.
But generally speaking, candles and kerosene lamps are considered luxuries for the vast majority of people.
Moreover, the reason why curfews were implemented in ancient times was not only for public security considerations.
The inability to provide sufficient lighting at night is also an important reason, and can even be said to be the core reason.
After all, without sufficient lighting at night, if there is a large flow of people, various contradictions and conflicts will easily occur.
For example, in the case of theft, it is dark and semi-lit at night. This kind of environment is most suitable for thieves to start.
If you go out with your wallet, maybe a thief passes by you and your wallet is gone.
Another example is a fight.
It was dark and half-lit at night, and it was difficult to see The Grand Pure One. One could not tell but stepped on or bumped into others.
If both parties are in a better temper, then saying sorry will be enough.
But if the tempers of both parties are not good, one can say "What are you looking at" and the other "What are you looking at", and a fight can start on the spot.
It's not surprising that someone can be injured at least, or even killed if at worst.
It can be said that it has greatly expanded the instability of a harmonious society and increased the cost for the government to maintain stable public security.
Unless the government can light candles and kerosene lamps everywhere to make the night as bright as the day.
In this way, the probability of illegal crimes can naturally be reduced.
But then, there is a new problem.
That’s the cost of candles and kerosene lamps. Who will bear it?!!
As I have just said, in this era, candles and kerosene lamps can be said to be a luxury product in a sense.
As for luxury goods, they are naturally expensive!
Candles and kerosene lamps are lit everywhere for lighting, which requires a lot of candles and kerosene lamps.
And this is not a one-time expenditure, but a steady stream of subsequent fixed expenditures.
If such a large expenditure were borne by the imperial government, it would definitely not be affordable.
So after considering all aspects, the best and most cost-effective solution is to implement a curfew!!!
In this way, the court does not need to bear huge expenditures on candles and kerosene lamps, but it can also reduce the probability of illegal crimes at night. It can also maintain the stability of a harmonious society and reduce the government's cost of maintaining public security.
In a sense, the curfew is a perfect solution.
In addition, candles and kerosene lamps have a third disadvantage, which is "eye damage"!!!
The light from candles and kerosene lamps is relatively soft, not bright enough, and also erratic, in a state of constant stimulation.
Reading under such light is harmful to the eyes. It may cause eye fatigue at least, or myopia at worst.
But this was before the appearance of electric lights. After the appearance of electric lights, to use a popular Internet phrase from Yan Changqing’s previous life, that is:
"Sir, times have changed!!!"
Yes, times have changed since the advent of electric light!!!
Small lighting range?!!
An ordinary carbonized bamboo filament electric lamp is enough to illuminate an area of more than ten square meters.
If you still dislike the small lighting range, no problem, there are arc lamps.
Arc lamp is the previous generation product of carbonized bamboo filament lamp, and it can also be said to be the first generation of electric lamp product.
However, because it is too bright, generates too much heat, and is not durable, it cannot be used in general small-scale indoor places.
So arc lamps were eliminated later [replaced with carbonized bamboo lamps.
But there is a saying that goes, there are no waste products, only people who don’t know how to use them.
Arc lamps are indeed not suitable for use in general small-scale indoor places.
But if it is in a palace of three to five hundred square meters like Zhu Yuanzhang's, or in a large square or street outside, then arc lamps are very suitable.
A high-power arc lamp illuminates an area of hundreds of square meters or even hundreds of square meters brightly!
After talking about the lighting range, let’s talk about the cost.
In addition to the initial investment of copper, magnets, waterwheels, etc. for the hydroelectric generator in front of us, if the wicks, wires, etc. are not broken later, then there is no need to spend any more money.
Rounding it all off, this is almost like free!!!
Although it’s only free where water power is available, it’s still free!!!
This alone is enough for tulle candles and kerosene lamps.
Let’s talk about the issue of light. Before the advent of electric lights, “like day” was just an exaggerated adjective.
But after the advent of the electric light, "bright as day" became a realistic descriptor.
In terms of brightness, candles and kerosene lamps are not suitable for electric lamps.
It can be said that regardless of whether electricity has other functions, just the fact that it can generate electricity for electric lights and allow the electric lights to continue to shine is enough for them to pay attention to.
Looking at the excited Zhu Yuanzhang and other civil and military officials, Yan Changqing walked to the windmill on the other side and said:
"In addition to hydroelectric generators, I also made wind turbines based on the same principle.
"As long as the wind blows through the windmill, the rotation of the windmill will drive the conductor rotor to rotate rapidly, which will also cause relative motion with the permanent magnet outside, causing the coil to continuously rotate in the magnetic field and cut the magnetic field, causing electromagnetic induction and then generating current. "
"Electrical current flows through the wires, producing electricity, which ultimately lights up the lamp."
"However, compared with water power, wind power is unstable, so for a long time, wind turbines will not be able to be applied in actual life."
"But using wind power to generate electricity can be a research direction in the future."
“In addition to hydroelectric generators and wind turbines, I and other craftsmen are currently also studying thermal generators.
"After all, there are not rivers available everywhere. If you want to truly popularize electricity, you must convert the generator from water power into another more common 'power'."
"And for this more universal 'power', I chose 'firepower'!!!"
"The so-called fire power refers to a kind of power produced by combustion."
"Whether it is firewood, charcoal, coal, biogas, oil, or natural gas, it can all be used as a source of fire combustion."
“So if thermal power generation can be achieved, then in the future it will be possible to generate electricity wherever firewood, charcoal, coal, biogas, oil, and natural gas are available.
"And when electricity can be spread to the whole world, then electric lights will naturally be spread to the whole world. Even at night, the world will still be as bright as day."
"And in addition to electric lighting, electricity also has other functions, such as heating, cooling, heating, cooking, electrolysis, etc."
"Compared with firewood, charcoal, coal, biogas, oil, and natural gas, there is no doubt that electricity, as a new energy source in the future, will be more environmentally friendly and convenient, have more uses, and play a greater role."
"It can be said that when electricity becomes popular in the future, the world will inevitably move from the age of oil and natural gas to the age of electricity!!!"
Zhu Yuanzhang and a group of civil and military officials looked at the electric lamp hanging above, emitting a blazing white light, imagining the future of the electric power era, and the world would be a prosperous world as bright as day after nightfall, and they couldn't help but be intoxicated.
.........
After a while, Zhu Yuanzhang woke up from his reverie, looked at Yan Changqing impatiently and asked:
"Has the thermal generator been researched and invented?!!"
After seeing the electric light, Zhu Yuanzhang was also greedy.
How could he live without such a good electric light?!
However, Yan Changqing shook his head and said:
"The principles and theories of thermal generators have been studied and understood, but there is still a long way to go before the theory can be turned into a practical thermal generator."
"So for now, thermal generators are temporarily unavailable."
The principle theory of thermal power generators is not difficult. In the final analysis, it is just three types of energy conversion processes: fuel chemical energy - steam thermal energy - mechanical energy - electrical energy.
Simply put, it uses fuel to generate heat, heats water, and forms high-temperature and high-pressure superheated steam.
The steam then enters along the pipe
The continuous expansion and work in the steam turbine impacts the high-speed rotation of the turbine rotor, driving the generator rotor (electromagnetic field) to rotate at high speed. The stator coil cuts the magnetic lines of force and emits electrical energy.
Then use the step-up transformer to increase the voltage to the system, connect it to the grid, and transmit power to the outside.
Finally, the cooled steam is further boosted by the feed water pump and sent back to the boiler to repeat the above cycle process.
The theory is that simple, but it is very difficult to make a thermal generator that conforms to this set of principles and theories.
So until now, thermal generators are just like steam engines, although Yan Changqing has guided the correct research direction, as well as related principles and theories.
But Yan Changqing doesn't know the answer to when actual usable thermal generators and steam engines will be produced, so he can only wait slowly.
0.--
Looking at Zhu Yuanzhang, who had a look of disappointment on his face, Yan Changqing couldn't help laughing and said:
"Although thermal generators have not been invented yet, hydraulic generators can be used temporarily according to local conditions."
"If your Majesty, or other civil and military officials, have a pond at home, you can ask your craftsmen to come over and learn from it."
"Hydraulic generators and electric lights are not difficult to make, but they may break easily.
"However, although it is easy to break, it is also very simple and convenient to repair and replace."
"Currently, I am planning to build hydroelectric generators and install related electric lights for lighting in some areas of the Academy of Sciences."
“In addition, several Saints from the Wanmin Agricultural College, Wanmin Medical College, Wanmin Liberal Arts College, and Wanmin Business School next to the Wanmin Academy of Sciences are also interested in hydroelectric generators and electric lights.
"At that time, I will work with Wanmin Agricultural College, Wanmin Medical College, Wanmin Liberal Arts College, and Wanmin Business School to build hydroelectric generators and lay related electric lighting.
.
Upon hearing this, Zhu Yuanzhang, who was originally disappointed, could not care less about his disappointment and immediately said:
"Let the craftsmen from the Academy of Sciences build hydroelectric generators wherever there are pools and rivers in our palace."
"Then all palaces that can be equipped with electric lights will be equipped with electric lights for us. We want electric lighting!!!"
[If there is no thermal generator, there will be no thermal generator. It is not impossible to make do with the hydraulic generator. 】
Zhu Yuanzhang was also very tolerant. It didn't matter whether it was a hydraulic generator or a thermal generator, as long as he could use it.
Anyway, after experiencing the electric light, he didn't want to use the original candle again.
Moreover, hydropower generation does not consume manpower, firewood, charcoal, coal, biogas, oil, natural gas and other resources, so it is "free" in a sense.
This is very in line with Zhu Yuanzhang's preferences. He likes free and easy-to-use things.
After hearing the words of Saint Ban Heng and Zhu Yuanzhang, the civil and military officials on the side also said:
“Saint is most virtuous, thank you Saint for being willing to teach us how to build hydroelectric generators and electric lights!”
"Afterwards, the official asked the craftsmen from the government to come and learn, and also asked the craftsmen from the Academy of Civil Sciences to teach them how to build hydroelectric generators and electric generators!"
"Saint is generous and willing to teach us the knowledge of building hydroelectric generators and electric lights, but we cannot accept it for granted. We also ask Saint to take over our "beam repair"
Let me express my gratitude!"
Naturally, Wenwu Baiyan was also very interested in hydroelectric generators and electric lights.
It's just that Zhu Yuanzhang is the emperor, so he can directly ask the craftsmen of the Academy of Sciences to repair his hydraulic generators and electric lights.
But a group of civil and military officials do not have such courage, nor do they have such qualifications to be said like this.
For them, if they can let the craftsmen from their own homes come over to "apprentice and learn skills" and let the craftsmen from the Academy of Sciences teach them how to build hydroelectric generators and electric lights, then
This is already their blessing.
