I was engaged in infrastructure construction in the Han Dynasty [Transmigration Book]

Chapter 585 [3 More] 585

In fact, this transformation is not difficult, the difficulty lies in whether the idea will work or not.

Whether it works or not, you have to try it out. The so-called wind energy conversion is actually a matter of adding three fans.

Because I don’t know the direction of the wind, there will be a vertical fan on the left and right, and then the two fans will be linked with a gear. Once they rotate, the rear gears will also rotate, and there will be another one under the two gears. The horizontal gear, when the gear rotates, it will drive the fan below to rotate, and then provide wind support for the flame.

Of course, the idea is very good, and it is not too difficult to implement, without the help of the Mo family or the public loser, the people under him can handle these things.

It’s just that I took a little thought when calculating the ratio. The fan should not be too big. After all, it is made of wood, and the bigger it is, the heavier it is.

After Liu Tan installed the fan on the hot air balloon, he tested it and found that it was okay, so he asked people to light the fuel to prepare for the test.

Then... a very important problem appeared. When the hot air balloon flew to a height of more than one person, it stagnated again-in fact, there is no wind at this height, unless you choose a windy weather.

So here comes the problem, if you choose a windy weather, then the wind in the sky may be stronger, and Liu Che will be blown to pieces by the wind, so what's the point of playing?

So if you want to make the hot air balloon fly, you have to manually turn the fan on the surface. Liu Tan thought about it for a while. In fact, this is not difficult, because it is impossible for him and Liu Che to go up, at least Make the balloon capable of carrying the weight of four people—the two of them plus the two eunuchs.

And whether it was Miao Rui, Bi Gao, or the eunuchs around Liu Che, all of them were actually quite strong, like the thin, small, and neither male nor female on TV, they would not be transferred to the Served by the emperor.

In such a case, it is enough to let those two people turn the fan manually.

For this reason, Liu Tan directly added a rotating handle to the fan.

Then he looked at the handle and thought for a while and said, "I feel... this thing can actually be used alone."

Isn't this thing a manual version of the fan?

Even if he came up with a method of using saltpeter to make ice, there will always be a period of time when it is not hot, but it is definitely not cool. It will be cold when using ice, but it will be a little hot when not using it.

Fans are usually used at this time, and the palace also has people fanning fans on the side.

But if there is a fan, it will save more effort than a fan, right?And the effect is better than the fan, the most important thing is that it looks novel.

Liu Tan thought for a while and decided to go back and get a blueprint and then a sample. Anyway, it's still early in spring and summer, so don't worry too much.

As for making by-products again, Liu Tan felt that this was already his basic practice, so there was no problem, don't panic, he can do it.

As for the hot air balloon, after having a handle and human experiments, the fan will start to rotate after rising to a certain level, and the hot air balloon will fly higher and higher, and finally maintain a height of about [-] feet, which is equivalent to six Miduo, it doesn't sound very high, but in this era, if you find a higher place to fly, you can overlook the entire Chang'an City.

And it's not that he can't fly higher, Liu Tan was restrained with a rope, for fear of flying too high and being seen by others, and now the place where they are experimenting is originally relatively low, and there are mountains around, and his The palace is not short, and this hot air balloon is a scaled-down experimental product, and it will be ignored if it is farther away.

And within a radius of twenty miles, there are no other people's manors, so this height should be just right.

Wanting a higher altitude, he planned to go to Qinling to test it inside to avoid being seen.

The next thing was to have people make the real-sized hot air balloons, while he went back to painting the fans.

The real fan must not be as simple and simple as the one on the hot air balloon. The handle needs to be longer, and a stand is needed, and the fan blades of the fan also need to be wrapped.

Liu Tan remembers that some of the painted bricks of the Han Dynasty that were unearthed in later generations already had pictures of fans, but the exact date of the appearance of the fan is uncertain. It is too general to say that the Han Dynasty is too general, at least Liu Tan has not enjoyed it since he came here. .

Because there is no electric drive in ancient times, the driving force is divided into many types, the most of which are probably hand-operated and foot-operated. People will need.

Liu Tan simply designed both, and will sell them when the time comes, and get a special edition for the noble and royal family by hand.

As for what the special edition looks like, it must be better looking and more gorgeous.

Liu Tan even thought about whether it is possible to draw a picture on each fan blade, and after turning it, a picture will be formed.

It's just that he remembered that the fans that could form patterns that he saw before were all very fast and had to be driven by motors. Now it's only human-driven and he doesn't know if it will work.

Liu Tan was a little reconciled, so he finally chose to give it a try, and then he found that as long as there were enough fan blades, the pattern on the fan blades would have a certain degree of integrity, and in fact, a certain pattern could be formed when it was shaken manually.

Then Liu Tan drew a lot of pictures in one breath, all of which were relatively simple. Liu Che's tangled painting of Qionglouyuyu, plus some divine beasts flying through the clouds and fog, and the like.

The style of the later generations is a bit too realistic in the eyes of the present, and may not be the style that people like today, but it doesn't matter... As long as it is related to the fairy world, Liu Che likes it.

As for Chen Ajiao, Liu Tan drew some cute animals for her, and she liked them anyway.

According to Liu... Liu Tan thought for a long time, and finally chose the scene of thousands of horses galloping on the snowy field. He probably liked it too.

These paintings made him grind for a long time. After he finished polishing the paintings, the hot air balloon was almost done. Liu Tan directly led people into the deep mountains and old forests for a test flight. After confirming that there were no problems, he happily prepared gone back.

Just at this time, he calculated that there was only half a month before Zhengdan, and when the Lantern Festival on the fifteenth day of the first lunar month came, Liu Tan could definitely ask Liu Ju to go to the sky to see the lanterns.

Participating in something like the Lantern Festival is to experience the world of fireworks, but if it is really good-looking, it must be from the perspective of aerial photography.

So in the winter, Liu Tan took the fan he made and went straight back to Chang'an.

After returning to Chang'an, he also knew that he should go to see Liu Che first, but he still couldn't hold back and sneaked back to the palace first.

At this time, Lu Xuan's injury was almost healed. Although the scar was still there, it did not affect his activities, and he didn't even need to avoid it.

After seeing Liu Tan, Lu Xuan walked over and picked him up and turned him around a few times. Liu Tan was caught off guard and almost fainted, so he quickly slapped him on the shoulder and said, "What are you crazy about!"

Lu Xuan put him down and smiled and said, "Why didn't you send someone to tell you in advance? I'll pick you up."

Liu Tan hugged him and rubbed his cheeks and said, "It's not that I have traveled far, it's not that I won't be there."

Lu Xuan actually had a lot of things he wanted to say, but at this moment he didn't want to say anything anymore, he directly held Liu Tan's face and kissed him.

Liu Tan embraced his neck and responded enthusiastically.

This time, it was Lu Xuan who stopped first, and while steadying his heartbeat, reluctantly let go of him and said, "Do you want to go back to the palace first?"

Lu Xuan is already used to Liu Tan's itinerary. Anyway, he is back, and because the Chinese New Year is coming, all the yamen of the imperial court are closed. Liu Tan probably has nothing else to do. There is always time to get together. Patience has always been good, I have waited for such a long time, and I don't care about a day or two.

But this time it was Liu Tan who was a little hesitant. Indulging in sex is not good, but even if you are married, it is not good to abstain from sex all the year round.

So Liu Tan turned to Miao Rui and said, "Go back to the palace and tell your father and mother that I just came back from the outside. .”

After Lu Xuan heard this, his eyes widened in surprise. Liu Tan played with the cloak strap tied around his neck, and said with a smile while pulling it inside, "I'm going to take a bath."

Lu Xuan understood and followed immediately.

Even though it might seem like a waste of energy to take a mandarin duck bath, Liu Tan has not been so indulgent for a long time, and he doesn't care about those things anymore, anyway, he has money.

However, he soon regretted staying tonight - Lu Xuan's body seemed to be really healed, so good that one tossed until the middle of the night, if Liu Tan hadn't blown his hair, he might still have the energy to continue.

However, Liu Tan didn't want to be seen by others when he entered the palace tomorrow. In fact, Lu Xuan restrained himself before, and then took a cold shower to calm himself down. sleep.

The next morning, as soon as Liu Tan got up, he heard that someone was visiting. When he asked, it turned out that it was an envoy from a foreign country. It seemed to be a small country in the Western Regions—a kind that Liu Tan had never heard of before.

Liu Tan asked with some doubts: "What's the situation? Who is this?"

While helping him organize his accessories, Lu Xuan casually said: "I don't know if you haven't been in the northern border country for a year, it's a bit chaotic over there, and a few small countries have been established, but don't forget, the strength is not very good, say It’s uncertain when the country will be destroyed.”

Liu Tan said, "That's not necessarily the case. When your father brought people out, there were not many people. Now, Wusun Kingdom has also become a hegemon in the Western Regions?"

After hearing this, Lu Xuan smiled and said: "That's true, but the few who came today have the shadow of the Huns behind them. It can be said...they are all supported by Xiaoli Lake."
