Chapter 746: Fruit Secondary Military Transport

A propeller is a propeller, and Li Yi made no detours when designing it.

He also calculated the propeller bit by bit and gave the data at the same time.

When the craftsmen were making the mold, they dug little by little and finally figured out the mold.

When there is no problem with the transmission, the propeller rotates and generates thrust that is unmatched by other propellers.

"My Zhuangzi craftsmen are the best. What five-axis linkage? What printing? Do I need it to be so precise?"

Li Yi was excited. This speed could scare the enemy to death in a water battle.

Li Chengqi, three adults and one child, obviously couldn't understand what Li Yi was talking about.

"Brother, I've figured it out. Let's not build steam engine trains first. If we want to build a business, we should build steam engine ships."

Li Yi was inspired and stopped worrying about the railway tracks.

Transportation requires speed, while countercurrent requires power.

Paddle ships can provide power, have a large force-bearing surface, and have lower power conversion ratios than propeller ships.

If a thousand-stone ship is equipped with propellers and steam engines, the journey from the Yellow River to Hukou Waterfall can save dozens of times of time.

The Yangtze River is even more powerful, and trackers have to change careers.

You don’t have to eat seafood, and with water transportation, all rivers that can pass steam engines and ships will become important transportation channels.

Everyone still doesn't understand steam engine trains and steam engine ships. The only thing they understand is that Li Yi can always come up with technologies that people dare not think of.

A ship that doesn't care about the direction of the wind can sail against the current at will, and now there is a faster ship that can sail against the current.

"Brother Yi, if you build this ship bigger, the merchants will take the initiative to pay the tax." Li Longji thought of a good idea.

Merchants can use such ships only by paying taxes and relying on receipts.

If you don't mind, just take your time and slim down.

Pulling fiber is not free, you have to pay the tracker. For the same goods, if one ship arrives first and the other ship arrives several days later, the tax will probably be compensated for the difference in price.

"Sanlang, can you eat fresh lychees from Shu by transporting lychees? Take the Han River and then use horses to relay."

Queen Wang has never eaten fresh lychees until now. What she thinks of is the lychees from Shu.

Historically, Concubine Yang ate lychees from Shu, not Lingnan.

Even if Lingnan Litchi traveled 800 miles, it would be too late.

Lychees from Shu can be delivered by flying horse in two days.

"Sister-in-law, it's easy to eat lychees. I have a way to keep lychees fresh for twenty or thirty days."

Li Yi thought of something important. Previously, candles were used to store things by consuming oxygen, but carbon dioxide exists and ethylene is also produced.

But there is still a way to preserve lychees, which is to control the growth reaction of lychees and keep them in a dormant state.

"What's a good idea?" Queen Wang's eyes widened, and the little guy stared in unison.

If anyone dares to keep lychees fresh for twenty or thirty days, Queen Wang will kick him into the water.

"Flute film, refrigerate. First wrap the lychees tightly with the film, then put them in a jar and put ice cubes outside."

Li Yi told him the method he could think of. The cost was high, but it was less expensive than using fast horses to transport things.

The film of the flute is peeled out of the reed. No matter how expensive the ice cube is, how expensive can it be?

Queen Wang blinked: "Wrap the flute film with ice?"

Li Yi nodded: "Yes, this method can be used for many fruits, such as bananas."

Li Yi swallowed hard as he spoke. Of course, he wanted to eat more than just bananas.

He doesn't have plastic film, so he can put several layers of reed film on it.

If you think the reed film will be breathable, apply a layer of glycerin after several layers of reed film, and then apply the reed film.

You can fight to eat.

Otherwise, how can I send something like bananas urgently?

Putting green bananas in your backpack and riding a horse at a fast pace?

Four people, no, not counting the little one, it was the first time that three of them had heard of this method of preservation.

"Brother Yi, is it useful?" Li Longji was tempted. He also loves to eat good food.

"First test the cucumber. Pick the cucumber, wrap it, and place it in a place with ice cubes around it. Do not stick it on it. Keep it at about four degrees above zero."

Li Yi was not sure, he had to try.

He used to wrap cucumbers in plastic wrap and put them in the refrigerator, and they were fine for half a month.

Change to flute film, if possible, then many fruits will do.

With the addition of new ships, fruits from the south can be transported to Chang'an to a large extent.

The premise is that no one is allowed to block the journey and the journey is smooth.

Li Chengqi looked excited. He had discovered a profitable business. Usually in places that were too far away, Yi Di was not in a hurry to operate, and it was all for him to make an alliance.

Yi Di's view on money is that when you need money, you should come up with something and make a lot of money.

When you don't need it, just sell things slowly and normally. Money never seems to be much, but there is always no shortage.

"Brother Yi, can you put the preservation aside and find a boat? Why do you say the propeller is fast in the water?"

Li Chengqi wanted to learn this.

Li Yi was speechless, brother, do you want to learn this? Work and pressure difference? Where do I start with you?

Then do you want to learn the principles of propeller blade curved surfaces? Do we still need to learn the distance ratio?

I don’t know how, it’s not an area I can get involved in.

After thinking about it, Li Yi decided to use a popular method.

"Brother, look, when the paddle wheel rotates, half of it will be above the water. When it turns to the top, it will be like swimming. Can you paddle with your arms on it?

One is paddling under the water all the time, and one is above the water half the time, with different paddling times.

Sink the paddle wheel into the water. When the wheel rotates, the water will settle first. As for the propeller, it keeps retreating.

There is only such a small area where it blocks the water. That is to say, the same strength is used in pushing, and half of the paddle wheel is idling. "

Li Yi can only introduce it this way, otherwise it will be too profound and others will not understand.

Li Chengqi listened, smiled and nodded, meaning... I went back and thought about this slowly, but I really didn't understand it.

Li Yi controlled the rudder and slowly turned a big turn, and the boat returned to the dock on the side of Lijiazhuangzi in Baishui. UU Reading www. uukanｓhu.net

The thin ice on the river was all removed and everyone got off the boat.

The little guy was held by Queen Wang, kicking his little legs imitating the way the adults just did.

"Brother Yi, when the river above the Hukou Waterfall opens up in the spring, we can put a boat like this on it to transport troops and equipment, and we can directly push it to Tubo."

Li Longji no longer thought about the problem of transporting fruit crispers. He discovered that the propeller made the boat faster.

It's easy to go with the current, but the difficult part is going against the current. It turns out that the ship is going to use a paddle wheel.

Things have changed now. Yi Di was bored and actually came up with a new thing.

The Hukou Waterfall boat track test was successful and the upstream and downstream can be connected.

The propeller boat placed below does not need to travel on the track. It is separated into two sections and used for other boats. It can be replaced when the time comes.
