Chapter 458

Episode 458: Changing People pt.2. (3)

The birth of the electric fan, or rather the wind frame, was directly influenced by incense.

Early summer is getting hotter.

Hyang loosely untied the official uniform he was wearing and screamed.

“What the hell! If you’ve made screws, it’s natural to think about making fans, too! “Why on earth am I supposed to endure this heat again?”

bang!

“I can’t take it anymore!”

Hyang immediately got up from his seat, immediately released his loose sympathy, and stormed out of the office.

Hyang continued to grumble as he walked to the workshop in charge of screw-related research and development.

“Say that for centrifugal blowers! Because the shape itself is different! But the screw came out! They even prepared the table for me! Do I have to scoop up rice and feed it to you?”

There was some truth to Hyang’s complaints. This was because it had been quite some time since the concept of a screw-type propulsion machine (recorded in the challenge log as a pinwheel-type propulsion machine) was introduced.

“The time that has passed since being registered in the challenge log is counted in years, not months! “If you can’t even think of variations like this yet, the problem is serious!”

As the scent wafted into the workshop, the researchers and craftsmen who were conducting research in the workshop all came out and offered their respects.

“I’d like to see you!”

“Thank you for your hard work.”

“Whatever you want to ask...”

Hyang got straight to the point when asked by the development manager, who saw Hyang’s displeased expression.

“The days are getting hotter, aren’t they? So, I came here to see if it would be a good idea to apply the propulsion device we are currently researching.”

The development manager’s expression became strange as he heard Hyang’s story.

“huh? “Why are you making that face?”

“Actually, I have done some research, but I have not been able to report it because there are still problems that need to be resolved.”

In response to the development manager’s answer, Hyang immediately ordered.

“If you have a prototype, please bring it.”

“yes.”

After a while, researchers and craftsmen from the development department brought two pieces of metal with large pinwheels attached.

Hyang, who was watching the mechanical device of two large craftsmen getting off the cart with a whimper, asked the development manager.

“Is it using a steam engine?”

“That’s right.”

In response to the development manager’s answer, Hyang continued speaking.

“Just looking at it, I see three problems. First weight. Second, the safety of the pinwheel. Third heat treatment.”

“That’s right. The first prototype weighs 120 geun (approximately 72 kg), and the second, improved version, weighs 110 geun (approximately 66 kg).”

“It doesn’t look that heavy, does it?”

“If you load all the ammunition and water, it weighs a lot.”

“is it? “Let me see where it goes.”

“yes.”

As soon as the direction was given, the development manager and his subordinates prepared for the demonstration.

We took the boiling water from one side and filled it in the water tank, and also moved the burning coals from the furnace and filled them in the crater.

Soon, the pressure of the steam engine rose properly, and the development manager who confirmed this moved the lever attached to the machine.

Fluffy, fluffy!

With a loud mechanical sound, the pinwheel attached to the machine began to spin and create wind.

Hyang, who had been feeling the wind for a while, looked back at the development manager.

“If you take it to Pocheong, they will be very happy. “It would be great to use it when interrogating criminals.”

As the heat generated by the steam engine, which was the power source, was blown by the wind, a wind of such high temperature that it could turn even a healthy person into jerky was blown.

“So what about safety?”

In response to Hyang’s question, the development manager held a long pole tied with radishes to the wing.

Puff!

The radish that touched the wing was instantly cut into pieces and scattered. The development manager put down the pole and explained to Hyang.

“Because of this risk, we installed a safety net on the second prototype. The weight has been reduced as well. However, the heat treatment problem has not been answered until the end.”

“Let me think about it a little more.”

“Yes sir.”

After comforting the development manager and the people in the development department, Hyang muttered quietly as soon as he came out.

“Wouldn’t it be okay to make a mold out of bamboo and apply paper to make wings?”

“High-quality Korean paper is tough, but if you spin it that fast, won’t it tear?”

“If it spins that fast, it’s likely to happen. But isn’t our goal now not a blowing wind, but a cool wind that creates comfort? “Then is there any need to spin that fast?”

“ah!”

“Such a number!”

Youngsil Jang and the development manager immediately exclaimed in exclamation at Hyang’s story.

Jang Yeong-sil opened her mouth with an excited face.

“Then the problem is almost solved. The second problem is that once you wind it, it takes at least half an hour (approximately an hour), but there are many solutions! “As expected, it’s me!”

“That’s too much praise.”

It was a scent that waved its hand with a humble face.

The development manager, who had been mulling over various solutions while listening to Jang Yeong-sil’s wind-up windmill and incense solutions, sighed softly.

“Whoa~. They say ‘a frog in a well’.... All the things I had worried about are in vain. “I will discard all the windmills I am currently researching.”

Hyang shook her head at the words of the development manager.

“It also has a use, so why discard it?”

“yes?”

At Hyang’s words, the development manager tilted his head, and Jang Yeong-sil’s eyes lit up.

Hyang, who saw Jang Yeong-sil’s expression, smiled slightly and asked Jang Yeong-sil.

“Director Jang, do you know what it is?”

Jang Yeong-sil answered Hyang’s question right away.

“Aren’t you planning on using it in the winter?”

“That’s correct.”

The development manager expressed doubts about Hyang’s answer.

“Is there any benefit in using ondol or a brazier in the winter?”

Jang Yeong-sil spoke on Hyang’s behalf in response to the development manager’s criticism.

“Doesn’t the ondol take time to warm up and the brazier only warms the surrounding area? But if you can blow the hot wind away, it will get warmer quickly. Of course, an ordinary house or bedroom can be filled with ondol alone, but wouldn’t it be too much for a place like a government office to have ondol?”

“ah!”

The development manager was greatly impressed by Jang Yeong-sil’s explanation.

In this way, the development of windmills for use in the summer and windmills for use in the winter began in earnest.

“How good it is!”

Sejong received the prototype of the summer windmill and truly enjoyed the cool breeze.

‘Creating a healthy pig.’ Although King Sejong had become quite healthy thanks to the training of Hyang, he was still quite obese.

Thanks to this, I sweat a lot in the summer and had to suffer from skin diseases due to the layers of clothing I had to wear.

In such a situation, the prototype of the wind frame made in Area 51 was like a ‘sweet rain in a drought’.

“What do you think?”

The ministers who were blowing the wind from the windmills installed on all sides of Geunjeongjeon responded immediately.

“This is truly a pleasure!”

As soon as the words were out, Kim Jeom and the Minister of Finance and Economy made a suggestion to King Sejong.

“This will truly be of great benefit as many people suffer from the heat during the summer! “I think it would be a good idea to mass-produce it right away!”

“We will analyze whether to produce it in the royal workshop or to represent it to a private company!”

King Sejong smiled and responded to the suggestions of Kim Jeom and the Minister of Finance and Economy.

“Do you think the Deputy Prime Minister and the Minister of Finance and Economy want to be hit by a wind of money, not just a wind? But I think it’s a good idea, so I’d like to think about it and report back.”

“I follow your orders!”

After the matter of the windmill was decided, King Sejong praised the Hyang.

“When summer comes, the people suffer greatly from the heat. Although this device cannot eliminate all the heat, it still helps you find your energy. You have created a truly remarkable object. “Thank you for your hard work.”

“That’s too much praise.”

Hyang humbly responded to King Sejong’s compliment, but deep down, he was resolute in his fighting spirit.

‘The fan is a stopgap measure! The biggest problem still remains!’

Fumbling with the sleeves of the dragon robe she was wearing, Hyang strengthened her resolve.

‘Definitely do it! Dress reform!’
