Bringing A System To Great Tang

The propeller is the propeller. When Li Yi designed it, he didn’t make any detours.

He also calculated the calculation of the propeller bit by bit, and also gave the data.

When the craftsmen were manufacturing molds, they dig a little bit and finally figured out a mold.

In the case of no problem in transmission, the propeller rotates and the thrust generated by other propellers is incomparable.

“My Farmstead craftsman is the best, what five-axis linkage? What kind of printing? Do I need that precision?”

Li Yi is excited, this speed, in the water battle , Can scare the enemy to death.

Li Chengqi, three adults and one child, obviously cannot understand what Li Yi is talking about.

“Big brother, I figured it out. Don’t build a steam engine train. To build a business is to build a steam engine ship.”

Li Yi came for inspiration, not to worry about the railroad tracks. .

What transportation needs is speed, and what is needed is power when flowing backward.

Paddle steamers can provide power, the force surface is large, and the power conversion ratio is lower than that of propeller ships.

If you install propellers and steam engines on a ship with thousands of rocks, a section of the road from Yellow River to Hukou Waterfall can save dozens of times of time.

The Yangtze River is even more powerful, and the tracker needs to change his career.

Seafood can be omitted, and water transportation is more logistics. All rivers that can pass steam engines will be important channels for transportation.

Everyone still doesn’t understand what steam engine trains and steam engine ships are. The only thing that I understand is that Li Yi can always come up with technology that people dare not imagine.

A ship that doesnt care about the direction of the wind can sail against the current at will, and now there is a faster, reversible ship.

“Younger Brother Yi, build this ship a bit bigger, the merchant will take the initiative to pay taxes.” Li Longji thought of a good idea.

Businessmen pay taxes and rely on receipts to use such ships.

If you don’t pay, take your time.

Spinning is not free, and money is required for the tracker. For the same goods, one ship arrives first, and the other ship arrives several days later. The difference in price is estimated to cover the tax.

“Third Son, can I eat fresh lychees in Shu with a transporting lychee? Walk through the water, and then use the horse relay.”

Empress Wang has been She has never eaten fresh lychees, what she thinks of is the lychees from Shu.

In history, Concubine Yang ate lychees from Shu, not from Lingnan.

Lingnans lychee is too late to use 800 Miles to expedite.

The lychees in Shu area can be delivered by flying in two days.

“Sister-in-law, its easy to eat lychees. I have a way to keep lychees fresh for 20-30 days.”

Li Yi thought of something important, and used candles to store things before. Oxygen method, but carbon dioxide is present and ethylene is also produced.

But there is another way. Preserving the lychee is to control the growth reaction of the lychee and keep it in a dormant state.

“What’s a good way?” Empress Wang’s eyes widened, and Little Brat stared at each other tacitly.

For someone to dare to say that keeping lychees fresh for 20-30 days, Empress Wang kicked people into the water with one kick.

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

The way Li Yi can like it To say it, the cost is high, but it is less than using the fast horse to transport money.

The flute membrane is peeled from a reed. How expensive is the ice cube?

Empress Wang blinked: “Use ice on the flute wrap?”

Li Yi nodded: “Yes, many fruits can use this method, such as bananas.”

Li Yi swallowed, of course, he wants more than just bananas.

He doesn’t have a plastic film, so he can set several layers of reed film.

If you think the reed membrane will be breathable, apply a layer of glycerin after a few layers of the reed membrane, and then stick the reed membrane.

To eat, you can fight.

Otherwise, banana this thing, what kind of urgent report can I send?

The green banana is packed in a backpack, riding a horse all the way?

Four people, no, Little Brat doesn’t count, three people have heard of this kind of preservation for the first time.

“Younger Brother Yi, easy to use?” Li Longji was tempted. He also likes to eat good food.

“First test with cucumbers, pick them off, wrap them, and place them in a place with ice cubes around them. They cannot be pasted. Keep them at about four degrees above zero.”

Li Yi is not sure, he has to try.

He used to wrap the cucumbers in plastic wrap and put them in the freezer. It was no problem half a month.

Change to a flute film. If it is possible, many fruits will work.

With the new ship, the southern fruits can be transported to Ch_ng’n to a large extent.

The premise is that other people in the middle are not allowed to stop, and the way is unimpeded.

Li Chengqi showed an expression of excitement. He found a profitable business, usually too far away. Younger Brother Yi didn’t rush to operate it, but gave him this alliance.

Younger Brother Yi’s view on money is that when you need money, you can take out something and make a lot of money.

When I dont need it, I sell things slowly and normally. The money never seems to be a lot, but there is always no shortage.

“Younger Brother Yi, is it okay to keep it fresh? Let’s put it aside and find a boat. Why do you say that the propeller is in the water and the speed is fast?”

Li Chengqi wants to learn this .

Li Yi is speechless, big brother, you want to learn this? Work and pressure difference? Where do I start to tell you?

Would you like to learn the principle of propeller blade surface? Is it necessary to learn to advance the distance ratio?

I dont even know it, its not a field that I can relate to.

After thinking about it, Li Yi decided to speak in a popular way.

“Look, big brother, when the paddle wheel rotates, half of it will be on the water. When it turns to the top, like swimming, can you paddle with your arm on it?

A person is always paddling underwater, and a person spends half of the time on the water. The time of paddling is different.

Sink the paddle wheel in the water. When the wheel rotates, the water will be set first , The propeller, it keeps retreating.

Its a small piece of water blocking, that is to say, the same force is used to push it, and the paddle wheel is half idling. “

Li Yi can only introduce it like this, otherwise it will be too esoteric for others to understand.

Li Chengqi listened, smiled nodded, meaning…I went back to think about this slowly, but I didn’t understand it.

Li Yi controlled the rudder, slowly turned a big turn, and the boat returned to the pier on the side of Li Family Farmstead in Bashui.

The thin ice on the river surface was all loaded up, and everyone got off the boat.

Little Brat is held by Empress Wang, and his two calves are kicking and kicking like an adult just now.

“Younger Brother Yi, when the river above Hukou Falls is open after the beginning of spring, put such a ship on it and transport the troops and luggage, and you can go directly to Tibet.”

Li Longji no longer thinks about the transportation of fruit crispers. He found that the propeller is fast.

It’s easy to handle downstream, but the difficulty is upstream. It turned out to be a steamer preparing to use paddle wheels.

Now that it has changed, Younger Brother Yi is bored, and actually brought out a new thing.

The ship track test of Hukou Waterfall was successful, and the upstream and downstream can be connected.

The propeller boat placed below does not need to follow the track, the two sections are separated, and the other boats are used to travel. When the time comes, just change it up.
