Datang romantic little landlord

The beautiful boss recalled it for a long time before nodding, it seemed so.

So, the copper wire that Niu Wu bought just now was discarded, and Li Wangyou sent him to the jewelry store in Hu County to buy silver wire for himself.

Although silver is not a common currency in Datang, it is also very common.

It is very common to be used especially to make ornaments and utensils.Naturally, there is no shortage of gold and silver threads in the jewelry shop, so Niu Wu bought a lot of them without much effort.

Although the silver wire made by hand cannot be compared with the industrial processing of later generations, it is still quite exquisite.Li Wangyou can only say a word about the superb craftsmanship of the craftsmen of the Tang Dynasty.

Seeing that Li Wangyou was about to wind the silver wire onto the stator, the beautiful boss called out to stop him.

"Wait, Wangyou, why do I seem to remember that when I was in physics class, the wires were wrapped around the stator?"

Li Wangyou didn't understand: "That's right? There are wires in Datang? Can we use copper wire or silver wire instead? What's wrong? Is there a problem?"

"Stupid, insulate! Isn't the wire insulated? You just wrap the silver wire on it, so what if you don't insulate it?"

Li Wangyou was taken aback by what the beautiful boss said, it seemed that it was true...

What a fool, this Tang, where can he find insulated wires?

259 You are really useless

In the backyard of the county man's mansion, the door of Li Wangyou's study was closed.

Afuluo and Peilan could only hear the voices of their husband and sister Changqing coming from the study from time to time.

Especially my husband, his breathing was quite rapid, as if he was doing some vigorous exercise in the room.

"Ah! Hurry up, hurry up!" Su Changqing's excited voice came from the study.

"Phew... I can't do it anymore, rest...let me rest for a while." Li Wangyou's panting voice came.

"Wangyou, don't stop, don't stop, keep going!"

"Huh, I'm exhausted, I can't do it, let me rest for a while before continuing."

"You're really useless, it's time to exercise."

"Hey, how do you talk, how can you say that men are useless? I have persisted long enough! Has it been half an hour?"

"Hmph, it's really useless, it's only 10 minutes at most!"

"..."

The little girl Pei Lan didn't know why, and wanted to knock on the study door to see what Chang Qing's sister and Lang Jun were doing, but was dragged away by Afuluo who was blushing.

Although Afuluo is a virgin, but in the barbarian wine shop, it seems that such voices are not uncommon...

However, there is naturally no picture made by Afuluo in the study, and it is not suitable for children to picture.It was Li Wangyou panting, constantly shaking the handle of the generator rapidly...

At one end of the generator, two silver wires were wrapped around the beauty boss's mobile phone charger. The data cable of the charger was connecting to the mobile phone, and the charging icon was displayed on the mobile phone.

Obviously, Li Wangyou succeeded in building the generator, and now he is charging his mobile phone.

Li Wangyou, a scumbag before, was baffled by Su Changqing's question. How to insulate metal wires is a very serious topic in Datang.

After pondering for a long time, neither Li Wangyou nor Su Changqing knew how to insulate the metal wire.

One thousand and three hundred years ago, where was the hand generator so well made?

The "generator project" that has been busy for a long time has not yet ended in failure, which hit Li Wangyou hard, and he was depressed for several days.

However, there is no way out, and Li Wangyou soon found a solution to the insulation of the metal wires—coating the wires with a layer of varnish.

China has recorded the use of raw lacquer a long time ago. "Shan Hai Jing · Bei Shan Jing" said: "Mount Guo, its wood is mostly lacquered brown. The mountain of Yingtar has more lacquered wood."

Raw lacquer is a pure natural liquid paint harvested from lacquer trees. Because of this, the output of raw lacquer in China has been low since ancient times, and the price is expensive, and non-rich and wealthy people cannot afford it.

Not to mention that it is impossible for ordinary families in the Tang Dynasty to use raw lacquer to paint furniture. Even in the families of the rich and powerful in the Tang Dynasty, there are not many people who can use raw lacquer.Because raw lacquer is non-toxic, it is often used to make tableware.

In Li Wangyou's mansion, there is a set of wooden utensils that have been painted with raw lacquer.

This was a congratulatory gift from a certain dignitary in Chang'an City after it was reported that he was conferred the title of Baron of Hu County.

Li Wangyou, who was still worrying about how to insulate the metal wire, saw the maid at home serving him food with this set of lacquered tableware when he was eating, and suddenly he had a flash of inspiration and remembered such a good thing as raw lacquer.

Li Wangyou couldn't help laughing, and he didn't care about the meal, so he immediately found Niu Wu and asked him to buy some raw lacquer for him.

Where can I buy raw lacquer?

Nature is still an omnipotent pharmacy...that's right, raw lacquer is still a kind of medicinal material.

"Compendium of Materia Medica": "Dry lacquer is used as medicine, mainly for the treatment of Juejuejinbuzhong, rejuvenating the muscles and bones, filling the marrow cells, calming the five internal organs, preventing five invasions and six acutenesses, and pinching the spleen due to wind and cold... It has the effects of repelling insects and relieving coughs."

Huaxia Chinese medicine is so awesome!

Well, all things can be used as medicine. Li Wangyou admires Huaxia Chinese medicine very much, and has been trying to figure out how they discovered that these weird things can be used as medicine?

And what is even more awesome about the ancient Chinese people is that they can keep raw lacquer from solidifying and hardening.

The method is to throw a few crab shells into the raw lacquer, so that the raw lacquer can remain liquid instead of drying and hardening.

The raw lacquer cut from Shandong, Gansu, Guizhou and other places is transported thousands of miles to Chang'an city for sale by relying on a few crab shells, which is very miraculous.

After Niu Wu bought the raw lacquer from the pharmacy in the county town, Li Wangyou soaked all the silver and copper wires in the raw lacquer, and after taking it out to dry in the shade, it became a simple enameled wire.

Finally, with insulating silver and copper wires, the "Datang Generator Project" that Li Wangyou had shelved for a few days had another chance to restart.

Carefully wind the enamelled silver wire on the stator, and firmly fix the magnet on the rotor. An extremely simple generator is completed.

But whether this thing can generate electricity, no one knows whether it is Li Wangyou or the beautiful boss.

If in later generations, connect a small light bulb and see if the light bulb lights up after shaking the handle, it will be clear.But Datang does not have such a thing as a light bulb. To test whether the generator can generate electricity, it has to rely on "human experiments".

Li Wangyou smiled and brought Niu Wu over, and asked him to hold both ends of the silver thread.

"Lang Jun, what are you doing?" Niu Wu asked stupidly.

Li Wangyou held back his smile, and pretended to be relaxed and said: "It's nothing, I made a little thing for you to try. Niu Wu, you pinch these two silver threads, don't let go."

The beautiful boss rolled her eyes violently, but she didn't stop Li Wangyou from being funny.

Anyway, besides the direct induction by the human body, she doesn't know whether the thing Li Wangyou created can generate electricity.

Niu Wu was confused, but he didn't feel that there was anything wrong. He held the two silver threads tightly with both hands, and watched Li Wangyou quickly shake the handle...

"Ah!" Niu Wu let out a scream, and instantly threw away the two silver wires he was holding.
