If there were no electric lights, and electric lights could be used in the team at any time, then the glass kerosene lamp in front of me would be like a magic lamp.

It is much brighter than other lights, ordinary people in the Ming Dynasty can't afford to use it, and it makes no sense for the rich to use it, money is an internal flow, and there is a way to get their money out through other means.

It is best only to sell to Yiren. Have the Yi people ever seen such a good thing? It's okay to let the Yi people exchange oil for it, right?

"Captain, is there oil outside?" Zhu Biao thought that it was not easy for him to pick that point, so what about changing it?

"Your Highness, during the Tang Dynasty, there were people over there who would simply purify oil and turn it into naphtha.

They did rough processing, because the local oil is light oil, and after a simple distillation, naphtha came out.

They use naphtha as a weapon of fire, something like our pump, to spray enemy ships when fighting at sea.

Wooden boats are most afraid of oil burning, they can't extinguish the fire, and on the water, it's impossible for you to turn around easily.

Once it is sprayed with naphtha, after ignition, the ship is gone, this tactic is very useful, and people are fooled every time.

Just as when our Ming army fought the Xia Kingdom of Sichuan, there was no way before, and then a sign floated upstream, which not only told us where the friendly army occupied, but also made the enemy's army confused.

After that, he carried the boat upstream, and in one fell swoop broke the iron cable across the river, because the upstream could set fire to the downstream. ”

The lieutenant told Zhu Biao that there is one outside, let them transport it over and exchange it with us, thirty to one, or twenty-eight to one?

"What's the difference between the two? Doesn't seem like much? No, that's nearly seven percentage points short! It's a lot worse, especially in terms of pure profit. ”

At first, Zhu Fan heard that there was not much difference between 30 to 1 and 28 to 1, and then he calculated that it was 6.6666 percent......

How much is the profit of the Danqing Box Hotel in Xiaqiu Village? What is the interest rate on borrowing?

The key is not the relationship between annual interest and monthly interest, but the profit difference of a trade.

Zhu Biao followed: "With the steam engine as the power of the ship, will it be possible to use electric lights?" ”

As soon as his words came out, Han Han, who always had a simple smile next to him, nodded when he heard it.

Yes drip! Once a steam engine ship is sailing, do you still need kerosene lamps?

Well! Yes, because the power system may have temporary failures, even if the dual system is guaranteed.

In fact, it is not considered so much, kerosene lamps are only used as a backup, and in normal cases, the power system of the steam engine can be connected to the generator at any time.

What can a ship floating on the sea do with electricity?

If the resistance wire is made, you will have an electric stove and be able to cook.

The lighting system is just as powerful, such as the higher wattage, the lamp with a lens, like a lighthouse, the light is far away.

Fighting at close quarters, it can interfere with enemy ships while also luring fish and increasing the protein intake of the crew.

Even if the ship is large, and there are many ships in the fleet, vegetables are grown in the cabin and lighting is provided.

During the night battle, the ships of the fleet complete the cooperation through the light language, yes, the ships fight at night.

Convert this electricity into light, and use the lens principle to fight the enemy's ships at sea at night.

In the current era, there are no conditions for not fighting in the sea at night.

The boat chase at night depends on the weather and luck, and there are stars and moon to find each other's boat and chase it down.

"Not only electric lights, but also electric motors are connected to the electric motor after there is electricity, which is used to collect anchors and transport goods as cranes, such as trawls, and the motor rotates when the net is collected." ”

Zhu Fan followed and said: "Can the ballista on the ship also be pulled apart by it?" ”

"It can provide power for the bed crossbow, but Your Highness, our Daming Sailor does not use a crossbow, but a cannon, and when you go back, Your Highness will see the smoothbore cannon that His Majesty let people cast, which belongs to the sub-mother cannon.

Use it first, and when we have our hands free, we can build better artillery, and we don't need to fight with the enemy, sink them, and defeat them before we get close.

The manufacture of firearms lies in standardization and refinement, and with the continuous and strong power supply, other auxiliary tools can be used. ”

The lieutenant first recognized that the motor could pull the string to launch the bed crossbow, and then told Zhu Fan that we don't need it.

"You can see a good cannon when you go back? There were artillery, bronze casting, and large muskets, which were not very easy to use, just as firecrackers were not as good as flintlock pistols. ”

Zhu Zhang's eyes lit up, looking forward to seeing better artillery, and he believed that the technology provided by Xiaqiu Village was definitely different from before.

"Your Highness, rest assured, with the improvement of the smelting process, there will be more and more good things in our Ming Dynasty.

So many iron ores have been dug up, and there are blast furnaces for iron smelting and open-hearth steelmaking, how can Your Majesty not use them to make weapons?

Our Ming craftsmen are amazing! Just give them some ideas and not be afraid to waste materials, and they can make something amazing. ”

"Yes, yes, we are not afraid of waste, not to mention that the iron is not good, it can still be used to make steel, the biggest advantage of the open hearth is to remake scrap iron and scrap steel into steel.

Let's use a few more lamps from this lamp, and take away all the oil, asphalt and paraffin.

When you get to the Northland, maybe you can use it, or at least you can make a fire, where the winter is cold.

I feel very cold now, the winter in Yingtianfu is not as cold as it is at this moment, it is only September. ”

Zhu Fan said coldly, and couldn't help but shiver.

The September he said is the lunar calendar, and the frost has fallen, and today is the 24th day of October in the Gregorian calendar.

The temperature is a few degrees lower, and the place near the river will freeze thin at night.

The key is that the wind in Xi'an is strong, whistling and blowing, bringing away all the heat on the surface of the human body.

……

Seeing the good things, Zhu Biao and Zhu Fan began to sell soap in order to improve the food for the craftsmen who repaired the palace.

The person who managed the greenhouse took over the logistics, and the former supervisor, Dai Feng, continued to supervise the project.

At night, everyone rested, and the lieutenant found Hanhan: "Can the gasoline be used to burn the enemy?" It doesn't feel like much use. ”

"Yes, put half of the gasoline in the glass bottle, and then use the cloth strip to extend it from the mouth of the bottle, let the gasoline soak the cloth strip, light it and throw it out when the fire is bigger, and burn a large piece.

Put a little sugar in it as a thickener The effect is better, anyway, it can be burned for a long time, and it sticks to the body and cannot be extinguished.

However, gasoline can be used to clear the oil stain, and if the paint is too dry, use gasoline to dilute it. ”

Zhu Wentian introduced a simple weapon, and then talked about industrial use.

The others had to wait for him to build an internal combustion engine, which was technically demanding and had to have spark plugs.

"Oh! It's better to dilute the paint. Those officials and supervisors had to take risks, so that His Highness would spare their lives. ”

The lieutenant chief turned to talk about the affairs of officials, and he was greedy for money for food, and the key impact was great.

They didn't dare to touch the money in the project, and they just bullied the craftsmen and the people.

"I won't make any money, but if I change it, not only will I not deduct the food expenses, but I can also add meals to everyone, and by the way, I will get benefits."

Zhu Wentian also felt that the officials were stupid, and now they all had to get back the greedy money and double the punishment.
