In the Academy of Sciences, by the small platform, there are Zhu Yunwen, the emperor of the Ming Union, five cabinet bigwigs, and two academicians of the Academy of Sciences.

More than a dozen eyes were staring at the metal sheet that was simply placed on the platform.

The emperor wanted to see the experiment, Jiang Tianliang hurriedly prepared, but he did not get close to the past to fiddle with it for the first time, but left first, and walked over with a plate in his hand.

On top of the plate, there were a pair of gloves, tweezers, a pile of iron pieces of the same size as a sheet of metal on the platform, and a container filled with water.

These pieces of iron are made of pure metal and silver.

"The gloves are made of rubber, as are the tweezers, so you have to wear them for this experiment."

Jiang Tianliang briefly introduced: "Rubber will not conduct electricity, otherwise human hands are easy to be injured by electric current, which will burn the skin and flesh at the lightest, and open the flesh at the worst." ”

Except for Zhu Yunwen, several members of the cabinet did not believe it, although they did not show it on their faces, they were very contemptuous in their hearts.

Although admitting that the Academy of Sciences has been miraculous over the years, if a few pieces of iron can break the skin of a human hand, then the big guy has been fiddling with those metal objects every day, how can nothing happen?

Jiang Tianliang didn't care whether everyone believed it or not, but after a few words of his brief introduction, he picked up a piece of metal zinc sheet with tweezers and put it on the platform, and then a piece of light cardboard, first clamped it into the container and soaked it, and then put it on the zinc sheet, and said in his mouth.

"It's salt water, which is used to conduct electricity."

When the cardboard is pressed, it becomes a silver sheet.

Then repeat this operation, three or three as a group, zinc sheet, cardboard, silver sheet.

When the stack reached the fifth group, everyone's eyelids jumped.

Because they saw that the surface of this small cylinder began to appear a small arc of electricity, and they even heard a crackling sound in their ears.

And when stacked to the tenth group, the electric sparks on the surface of the high cylinder can be seen clearly.

Can electricity really be generated?

"That's an unstable charge, the current is too strong and difficult to control."

Jiang Tianliang looked at this metal cylinder, very dissatisfied, and left again, holding a small silver wire in one hand and a 'squeaking' mouse in the other.

"The next may be a little unsightly, Your Majesty and a few pavilion elders to atone for their sins."

Jiang Tianliang said first, then put the mouse on the plate, tied it with silver wire, and then clamped the other end of the silver wire with tweezers, and gently put it on the top edge of the metal cylinder.

The arc flowing on the surface of the cylinder instantly seemed to have a place to go, and it passed along this silver wire in an instant, so fast that it was impossible to see it with the naked eye.

But everyone heard a 'crackle', followed by the rat's scream of pain.

The electric fire exploded, and the whole rat was beaten to pieces, the flesh and blood were blurred, and the dead could not die anymore.

The unpleasant stench spread, and several ministers subconsciously covered their mouths and noses, but their eyes were full of shock.

It's horrible!

If there is more electricity, if it hits a person?

That's not alive like thunder, splitting people to scorched bones.

"You're, how did you come up with this experiment?"

When Zhu Yunwen asked this, his tone was somewhat trembling.

Human society has entered the modernization of two factors that cannot be ignored, steam and electricity!

Steam has been born in Zhu Yunwen's expectations, he thought that he would not have the opportunity to see electricity in this life, after all, he had even forgotten the basic knowledge of electricity, and there was nowhere to guide it, but today's surprise came too suddenly.

"Last year, the minister looked through a lot of books left by the old craftsmen, and there was a record of the lightning strike Buddha statue in the "Book of Nanqi", and the minister was interested after reading it. Why did the lightning strike the Buddha statue, the golden Buddha was destroyed, and the door was not cracked?

And "Sou Shen Ji" said a lot, the ancient sharp weapon, the tip of the halberd spear can explode electricity, cited as a divine soldier, the minister guessed, but because of the metal conduction.

Ancient books such as "Mozhuang Manlu" also recorded frictional electricity, recorded the occurrence of various lightning such as leather static electricity and metal lightning. Aluminum, zinc, tin, cadmium, antimony, bismuth, mercury, iron, copper, silver, gold, platinum, palladium and other metal sheets of different qualities, carried out a variety of combination experiments, and sure enough, let Chen find out the reason.

Once different metals come into contact, the surface will produce an electric charge, and the electric charge has positive and negative poles, which are repelled by the positive and attracted.

And with the opposite charge, there is a voltage, that is, the potential difference between different metals, so that there is an electric current.

This kind of electricity is the same as the thunder and lightning of the celestial phenomena, the static electricity generated by the fur, and the electricity generated by the friction between the hair and the comb, but the difference is that this kind of electricity is the electricity that we can control, and the electricity that we can control! ”

Nikus Tesla, the man who wields electricity and is known as the closest to God?

I don't know why, looking at Jiang Tianliang, this memory fragment suddenly appeared in Zhu Yunwen's mind.

"When the thunder and lightning explode on this day, it will be as bright as day in the middle of the night, since you have discovered the controllable electricity, how to apply it to the field of lighting, is the main direction of your next work."

Lighting is definitely more important to the current Ming Dynasty than the development of telegraph, the field of information.

Only by laying a good foundation first and then pursuing those high-tech fields is the last word.

With lighting, the construction speed, development speed, and operation speed of the Ming Dynasty will be doubled, because the Ming Dynasty has inexhaustible human resources, and the Ming Dynasty, as a country that occupies a major leadership position and has absolute hegemony, is enjoying the demographic dividend in the Ming Union system.

What maximizes the value of all the utilization of the demographic dividend is to increase the intensity and depth of squeezing.

Without strong lighting equipment, how can you do those time-consuming and laborious infrastructure?

Although it is possible to rely only on traditional lights, it requires a lot of human lives behind the scenes.

The life and death of laborers can be ignored by Zhu Yunwen, but blindly filling in people's lives will not bring much improvement in efficiency, and he can't bear it.

A laborer boarded a ship and went to India to send Daming, and the food, drink, and clothing along the way were all state money.

The use value has not been squeezed yet, but it fell to death because of the night construction, fell into the river and drowned, thanks to it.

"Today's trip to the Academy of Sciences, there are too many surprises for me, I am very pleased, Elder Xu Ge, the cabinet has approved a note to give these academicians of the Academy of Sciences an additional salary."

"Eh, the minister will do it when he goes down, and he will be issued for two months."

Xu Buji, who was behind him, was full of promises.

On this side, Zhu Yunwen was also satisfied, and was about to leave, when Mo Cheng came up and shouted again.

"Your Majesty, slow down, here, there is another good thing."
