Chapter 51 Hot Air Balloon

The sky screen switches again and the scene is outdoors.

[I don’t know if you have ever heard a song: I want to take you to romantic Turkey, and then go to Tokyo and Paris together.]

[What do you think of when you think of Turkey? No, no, not kebab and ice cream, what else can you think of besides these two? ]

[Oh, yes, it’s a hot air balloon. Today is UP’s first time. I mean the first time I took a hot air balloon flight.]

[I am in this scenic spot now. Look, the big brothers are inflating this hot air balloon.]

As he spoke, he turned the camera to the side. From the sky, one could see a shriveled, colorful hot air balloon (cloth) lying on its side on the grass. One could also hear the crackling sound of a flame being lit, and then as the burning gas filled the hot air balloon, it slowly swelled up into an oval shape.

During the Zhenguan period, Chang'an City.

A group of civil and military ministers automatically ignored the tune-deaf humming of the young people in later generations, and their eyes widened when they heard the five words "hot air balloon flying", because when Tianmu mentioned hot air balloon flying, he specially added a video of a hot air balloon flying into the sky. Looking up from the ground, the hot air balloon was flying in the air, with the beautiful sunset in the background.

Looking at the shape of the hot air balloon, it is very similar to a Kongming lantern, it is simply an enlarged version of the Kongming lantern. However, it is different from the extremely fast, bird-shaped machine seen in the sky before.

"This must be a Kongming lantern!" many officials whispered.

"It really looks like a Kongming lantern!" Many officials were also surprised as they watched the hot air balloon gradually inflate.

"What kind of hot air balloon can fly? Does it mean that Kongming lanterns can also carry people to fly?"

Everyone looked at me and I looked at you, and finally said uncertainly: "It should be okay."

However, compared with the Kongming lantern, this hot air balloon has a large "bamboo basket" under it, which contains the
Li Shimin carefully observed every detail, and finally his eyes fixed on the round thing. It looked familiar, but he couldn't remember what it was for a moment.

Then he pointed to a cylindrical object on the sky and asked, "What is that?"

The ministers also felt that it looked familiar, and soon someone remembered: "It's a gas tank!"

"I vaguely remember that Tianmu mentioned before that gas cylinders were mainly used for cooking in later generations, and later they were used as weapons in war zones."

As soon as these words came out, Li Shimin's memory was awakened.
"Gas tank, gas. Could it be that the thing burning right now is related to coal?" Li Shimin narrowed his eyes, but he didn't see any black coal. He only saw that thing... spewing fire for no apparent reason.
Fang Xuanling's eyes widened, but he still couldn't figure out what was going on.
"Is it filled with gas?" someone asked uncertainly based on the name.

"Ah???" Everyone had also experienced the rigor of naming in later generations, and they were skeptical about this statement. However, they could not connect the black coal with gas.

And compared to the black coal which is hard to burn and produces a lot of smoke, why is there no thick smoke when this gas tank burns?
Everyone present here is a smart person. This situation can only mean that there is some method that we don’t understand in the process of turning coal into this bottled “gas”, which seems to be able to turn coal into “gas” and make it burn without smoke.

This corresponds to the status of coal in the video that mentioned oil.

It turns out that coal is really that important. Just like oil, no one cared about it for thousands of years because no one knew its importance and usage. Li Shimin couldn't help but pay more attention to coal.

The garden is full of spring.

Women such as Gan Tang and Qing Sha also recognized that the hot air balloons and Kongming lanterns in the video were very similar.

Moreover, the scenic area where it is located has beautiful scenery.

"So beautiful!" All the women were intoxicated by the mountains and rivers on the sky. The towering peaks were shrouded in mist, the foot of the mountains were surrounded by fertile fields, and the rivers flowed through the overlapping peaks, just like an ink painting. This was a terrain they had never seen before.

[The structure of a hot air balloon is extremely simple. It is mainly divided into three parts: the airbag, the basket, and the ignition device. The ignition device here is this gas tank, which is used by almost every household.]

[The hanging basket is mainly used to carry tourists. The airbag is mainly made of nylon. Especially here near the ignition point, fire-resistant materials must be used.]

[We learned about the flying principle of hot air balloons in junior high school. When the air is heated, its density decreases. Since the air density inside the balloon is less than that outside, it will experience an upward buoyancy. When this buoyancy is greater than the gravity of the hot air balloon and the tourists, the hot air balloon will naturally float up.]

[In order to be able to take off normally, the airbags of hot air balloons we see are generally larger, otherwise they will not be able to rise]

[Based on the principles mentioned above, we know that controlling the rise and fall of a hot air balloon is also very simple, that is, just ignite and turn off the fire]

[Then the smart friends will ask, how to move forward and backward or turn in the air? 】

[Unfortunately, hot air balloons cannot perform this type of operation. The hot air balloon flights we see in various videos are actually the result of the hot air balloons being thrust by the air flow after they are launched into the air and flying slowly. In other words, they are affected by the wind, so it looks like the hot air balloons can fly.]

[In fact, if you can control the direction of air currents, long-distance flights are not impossible. For example, in 1785, French pilot Blanchard and his deputy Jeffreys flew across the English Channel in a hot air balloon.]

[In 1987 and 1991, humans achieved the feat of flying across the Atlantic and Pacific Oceans respectively. In 1999, Piccard and Jones achieved the first round-the-world flight in a hot air balloon.]

During the Hongwu period, Jinling City.

Without Zhu Yuanzhang's order, clerks had already recorded what was mentioned on the sky curtain.

As the records were kept, many people were surprised that hot air balloon flying was so simple and within easy reach.
Thousands of years have passed since the invention of the Kongming lantern, but no one has achieved manned flight.

The reason for this is nothing more than one, that is, the whole society from top to bottom has a sense of superiority at work, thinking that this is just a gimmick and not worth mentioning.

From a structural point of view, it is not difficult to make a hot air balloon. The only difficulty is probably the sealing and weight of the airbag, which is obvious.

Zhu Yuanzhang hid some of his thoughts in his heart, and there was some excitement on his face. The dream of flying is everyone's childhood dream, and he is no exception. He had fantasized about it when he was young, and even often dreamed of flying at night.

Although the flying of a hot air balloon is different from what I imagined, it is still flying.
In addition, he also had some impression of the gas tank.

Coal can really burn, and looking at the sky, there is a pipe coming out of the gas tank, and there is no yellowish smoke when it is burning at the opening!

The technology here is also very important. If every household had it, perhaps they could fight the cold of the Little Ice Age and save countless lives.

Zhu Biao, Hu Weiyong and others were quite excited. They wanted to see the view of the ground from a hot air balloon, and they also wanted to try it themselves.

Hexing Tea and Snack Shop.

Everyone was discussing it enthusiastically, and they all started to get excited as they talked.

“If only I could sit here once!”

"What does it feel like to sit on it?"

"Don't worry, this young man will definitely go up, we will know soon!"

[The time span is so long because of the early fuel problems that made long-distance flights difficult, so it was shelved for a century and a half] [In the early days of the invention of hot air balloons, the fuel used for hot air balloons was combustible materials such as dry straw. Since straw was heavy and could not be burned, it could not fly far.]

[Okay, it’s our turn now. Let’s go up first.]

It can be clearly seen from the sky that it is a thigh-high basket. It is not very big and can only accommodate four people besides the gas tank.

There is also one operator, and several people are arranged to stand at the four corners.

The view turns to the inside of the hot air balloon's airbag, and you can see that it is empty inside, with only the orange and red color of the airbag visible.

Then you hear the crackling sound of flames, and then the hot air balloon slowly rises.

Although it is said to be rising, in fact I didn't feel much. I just felt that I was getting farther and farther away from the ground. At the beginning, I could see the grass on the ground clearly, but then I could only see green. I saw the shadow of the hot air balloon on the grass gradually getting smaller, and then it was difficult to estimate the distance.

Many people began to feel uncomfortable and dizzy.

There were quite a few comments at this time, and many of them left many people confused.

《Bullet screen: Press E to board the hot air balloon, press ENTER to take off》

《Bullet screen: What kind of game is so real, so dizzy》

《Bullet screen: Is the inside of a hot air balloon so small? 》

《Danmu: Press SPACE to spread the wings of wind.》

During the Hongwu period, Jinling City.

Everyone stared with wide eyes. In order to prevent the hot air balloon from flying away, they could see that the basket was tied with several extremely long ropes.

As the hot air balloon took off, the perspective of the sky began to shift, and everyone saw the roofs of residential houses not far away, and the usually very tall trees were also shrinking.

Looking into the distance, there are bare brown mountains in the distance, and the water of the river at the foot of the mountain is yellow, winding away. This is a scene that has never been seen on the ground before.

At this time, it was already very high from the ground. No one could estimate the exact height. All they could see was that the people on the ground became very small. They could vaguely see the young man in white clothes blocking the sun with his hands, and the guy in red clothes next to him was looking up with something pointing at the hot air balloon.

There were also bursts of fire and screams from several people on the hot air balloon.

"Is this the perspective from a hot air balloon?" Zhu Biao couldn't help but say. This perspective is similar to the one from the mountain, but compared to the view from the mountain, there is a feeling of freedom.

It would be even better if there was a gust of wind to blow it up.

Then there were the sounds of several people talking in the hot air balloon.

“It’s risen to the highest level!”

"It's OK if it doesn't shake, but it's not OK if it shakes!"

"You're scared, aren't you?"

"A bug bit me just now."

"What will happen if I jump down?"

"I think he'll die."

"Brother, please take a photo for us!"

"Come, come, stand in the middle!"

Hexing Tea and Snack Shop.

The shopkeeper couldn't help but smile as he listened to the conversation between the few people.

Judging from the perspective of the sky, the hot air balloon has probably risen to the hillside of the nearby mountain. Boats can also be seen sailing in the yellow river at the foot of the mountain.

And from the barrage, I learned that this place is called Guilin, and it must be in the south.

"Wow, this game is too real [dog head]"

"What kind of configuration is this? How can this game render so realistically [dog head]"

《550W, Earth OnLine》

"Where is this?"

"Karst landforms, Guilin at first glance"

"Locals do not recommend going to the big banyan tree in Yangshuo, Guilin"

During the Zhenguan period, Chang'an City.

Although it was basically the young man from Tianmu who was muttering to himself, Li Shimin felt somewhat happy after reading it.

The generals looked at each other and saw the eagerness in each other's eyes.

This thing might be of great use in the military after some modification, but...other than that, Cheng Yaojin and a few others looked at each other and decided to make one to play with and give it a try first.

Even though I just lifted off into the air in the end and couldn't fly because I was tied with ropes, the feeling was definitely different.

Nanjun in the late Han Dynasty.

Before the others could react, Zhang Fei had already rushed out and started to arrange for people to make a hot air balloon.

Liu Bei smiled helplessly and let him go.

Several people focused on discussing whether the gas tank actually contained gas.
Then they got stuck on how to convert coal into gas.
