The young man in front of him turned out to be the emperor, which was a little bit beyond Liu Ziguang's expectation. Mainly because he felt that the emperor was too far away. He was like a puppet sitting on a dragon throne. He could walk out of the palace, test-fly gliders, gamble and fight, and sell duck blood vermicelli soup.
, the bohemian young man who followed him to rob is actually the supreme ruler of this empire, which is quite a bit of black humor.
Liu Ziguang did not immediately lie down on the ground and kowtow three times. He just bowed his head and clasped his fists and saluted: "Liu Ziguang, a common man, comes to see Your Majesty." Yesterday he was just a little brother, and today he had to kneel down and kowtow. He couldn't accept it.
Wei Zhongxian shouted: "How dare you not kneel down when you see the current emperor. Come on, take it down for me."
Zhu Tianxia glared at Wei Zhongxian and said: "Brother Liu, a great man from this world, how can he be like a vulgar creature like you? I just want to have a friend like Brother Liu, not a kowtowing bug."
Then he explained to Liu Ziguang: "My emperor is actually just a title. I can't appoint officials or issue imperial edicts. I have Xiao Xianzi, a slave with Dongchang status, to handle things outside. Even the money in the inner treasury can't be used."
You can't withdraw money at will. Forget it, let's not talk about this anymore. Brother Liu, come and visit our factory."
The little emperor's factory was of all kinds, including potters, carpenters, blacksmiths, and stonemasons, and all kinds of strange processing equipment. Liu Ziguang couldn't understand how to use it. After listening to the emperor's introduction, he understood that the order of processing was arranged like this.
: The little emperor first comes up with an idea, and then the designer draws the drawings, carves the model out of hardwood, and conducts repeated experiments. If it works, it will be produced. A mold will be made out of clay, and the molten iron will be poured into it to cast it.
Specific and detailed parts are carefully forged by blacksmiths and jewelers. A good idea is that commonly used parts such as gears, chains, air ducts, bearings, pulleys, etc. are all standardized and available in various models from small to large.
, so you don’t have to design duplicate things every time.
Scientific and technological personnel have played a big role! Now the production technology of the Ming Dynasty has become relatively advanced. What is lacking is breakthroughs in thinking and technological innovation. Liu Ziguang proposed to take a look at the designers.
This is a large room. A dozen people in long robes are leaning on their desks, holding thin pencils, rulers, compasses, triangles and protractors to draw pictures on pure white thick white paper.
"Some of these people were recruited by me from the Manufacturing Bureau of the Ministry of Industry, and some were hired by private masters with high salaries, but they are all treasures. They are full of fantastic ideas. When my ideas come to them, they can be turned into living objects. By the way.
, there is a magical night-bright arc lamp, Brother Liu, come over and take a look."
Following the little emperor, he entered a house. The windows were blocked by black curtains, and he could not see his fingers in the house. With a cry of "bright", a dazzling light emitted from the beams, illuminating the house as if it were daytime, even brighter than before.
The daytime is even brighter, almost as bright as the poisonous sun on a sunny day in summer.
Liu Ziguang squinted his eyes and took a closer look. It turned out that they were two parallel carbon rods. An electric arc was drawn between the tops of the carbon rods, emitting a strong light. However, the light was too dazzling. It was enough to be used in a square. If it was used as a
The reading table lamp in the study room will definitely blind your eyes, and it also has a pungent smell.
"How about it, it's bright enough. No need to burn gas or lamp oil. My current wish is to turn the candle holders in the palace into night-bright arc lamps. It's a pity that the Queen Mother is not even willing to light the gas lamps, let alone this
More advanced night lights." The little emperor's words were regretful.
I can't let you hang these dazzling things all over the palace, Liu Ziguang said secretly. "The luminous lantern is really an artifact. If used in a night battle, it will definitely make all enemies invisible. I wonder what is used to light this artifact?"
"This is what is used." Following the direction of the little emperor's finger, Liu Ziguang saw a bunch of strange objects. White and yellow metal sheets and wet thick paper were piled together, and two metal wires were connected to the arc lamp.
.should be an original battery.
"This is a battery made of zinc sheets, thick paper sheets soaked in salt water, and copper sheets stacked in sequence. It means a battery that stores electricity. It can provide electricity for arc lamps to burn for several hours. However, the carbon rods of arc lamps are also getting more and more expensive.
The shorter it burns, the more it will have to be replaced after a few hours, so ordinary people cannot afford this kind of magical object and its consumable materials." The little emperor introduced.
The products of the laboratory have no practical value, Liu Ziguang concluded about the arc lamp, but the invention of such an electrical thing would greatly promote the progress of society.
The little emperor continued to explain: "There is something better than a battery that can generate electricity. Brother Liu, please go next door and take a look."
When I came to the next room, there was a turntable like an iron millstone placed in the middle of the room. A strong bull was circling the turntable. The bull pushed the disc to rotate slowly, like a flat bicycle pedal.
It is a thick chain. After passing through several small gears, it drives a larger disc in the distance to rotate. It is similar to the principle of a variable-speed bicycle. The small wheel drives the big wheel, and the speed becomes faster. There are
A rotor wrapped with copper wire rotates rapidly between the two poles of a strong magnet.
"This is an animal-powered generator. The same principle applies to wind turbines and underwater generators. Electricity cannot be stored and can only be used immediately. Now, in addition to arc lamps, electric-driven drills, lathes, grinders, etc. can also be used.
Come and drill the semi-finished product of the machine and cut it into a special shape. The only drawback is that the power is not strong enough and is not as powerful as the steam engine."
"Then why not use a steam engine to drive the generator?" Liu Ziguang thought quickly.
"Brother Liu means to use the push rod of the steam engine instead of the power of the cow?" the little emperor asked.
"Or even closer, wouldn't it be more convenient to use steam to directly push the wheel to rotate? Use good steel to build a pressure-resistant furnace to generate high-pressure steam, just like how strong winds drive a windmill. Arrange a few blades on the wheel, and the power of the steam
It is much larger than a windmill, so the electricity generated in this way will be more and stronger." Liu Ziguang described the steam generator set as a small thermal power plant.
"Wheels, blades, is that thing the propeller you mentioned? I asked someone to make a model. Brother Liu, please give me some pointers." The little emperor has a bit of a jumping mind and can easily associate one thing with another.
The propeller power model is a small boat driven by a clockwork, and there is also a model of a clockwork-driven paddlewheel boat of the same specifications for comparison.
Two small boats are placed in the pool and wound up
, started at the same time, the paddle wheel boat turned over the water and drove forward unhurriedly, while the propeller boat ran very fast. Because the propeller rotated underwater, the thrust generated was not wasted, so the speed was far faster than the paddle wheel boat.
Another experiment was conducted, this time the sterns of the two boats were connected with a rope to engage in a tug-of-war competition. The expected result was that the propeller boat won again and even towed the paddle boat backwards.
The experiment to verify the efficiency of the propeller in the air led to a major innovation in shipbuilding technology. In the future, steamships no longer need to hang two huge waterwheels. The idea of this invention came from Liu Ziguang, and the specific implementation was indeed
It's the emperor himself.
Of course, the little emperor had known the results of such an experiment for a long time. When he came back that day, he explained the principle of propellers to the designer. Several craftsmen used bamboo to make more than a dozen types of propellers, including two-bladed, three-bladed, and five-bladed propellers.
, parallel, angled, long, short, wide, narrow. After comparison testing, it is more efficient to use short and wide ones underwater.
Since there is currently no power source of suitable weight, the designers are planning to build a pedal-powered propeller under the delta wing. Most of the components are made of lightweight bamboo and wood. Only the runner and chain are made of metal.
The blades are made of wood. It is said that the finished product is going to be made of expensive aluminum alloy. Of course, due to the rush of time, all this is still on the drawing board.
"Your Majesty is very keen on flying?" Liu Ziguang asked.
"Yes, just like you said, sitting on the wings of the Flying God, you can reach places thousands of miles away from Chang'an and Beijing in one day. It's like the world is close." The little emperor looked up at the sky.
The flying bird squinted its eyes and said with longing.
"Then it doesn't necessarily have to be in the form of flying divine wings. Does Your Majesty know about the Kongming Lantern?" Liu Ziguang said that there are many things that can fly, hot air balloons are the easiest, and then there is the Kirov airship in Red Alert. After the development of internal combustion engines,
, and can also make a real airplane.
The little emperor thought for a while and said: "Of course I know. According to legend, it was invented by Zhuge Kongming during the Three Kingdoms period. At that time, Zhuge Kongming was besieged by Sima Yi in Pingyang and could not send troops out of the city to ask for help. Kongming calculated the wind direction and made a paper lantern that would float.
The main body of this kind of lantern is mostly made of bamboo grate, and then tissue paper or paper is used to form a lampshade. The bottom bracket is composed of a grate cut from bamboo. The Kongming lantern can be large or small, round or rectangular. The general Kongming lantern is
Use bamboo pieces to form a barrel shape, densely surrounded by thin white paper with the opening facing down. When you want to light the lamp and take off, tie a piece of coarse cloth or gold paper dipped in peanut oil in the middle of the bottom bracket, and ignite the oil before flying.
After the fire in the lamp burns for a while, hot air is produced, and the Kongming Lantern expands. When you let go, the entire lamp will slowly fly into the sky. If the weather is good, the Kongming Lantern will automatically descend after the kerosene at the bottom is burned out."
"It can be big or small! If you make a big Kongming Lantern, it is enough for people to sit on it. Can it go up to heaven? Your Majesty is learned and memorized, and I admire you greatly." Liu Ziguang said humbly. The little emperor is indeed a talent.
Worthy of admiration.
The little emperor slapped his thigh: "Here you go! If you install a big Kongming Lantern and a coke-burning stove to generate heat, you can take people to the sky. I will let people do it. Brother Liu really wakes up dreams with one sentence.
The middle man."
The little eunuch on the side wrote down what the emperor told him about the development of a large-scale Kongming lantern, and went there. The emperor pointed to the pavilion on the rockery stone and said: "Let's go up and have a chat."
Several young eunuchs quickly ran up and cleaned it quickly, and laid out a golden cushion and an ivory cushion to serve as seats for the two of them.
The little emperor sat in the pavilion, waved the little eunuchs to leave, and said seriously: "Liu Aiqing, do you think I summoned you today just for the propellers and internal combustion engines?"
Haha, the title has changed, I have become Aiqing, and finally it’s time to get to the point.
