Since Sun Yi demonstrated "lightning" that night, many craftsmen have become interested in "electricity" and often come to Sun Yi to study together. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

With the help of craftsmen, Sun Yi's tin can battery also became shapely.

Each battery is now covered with plaster to prevent contact with each other, and each of the nine batteries is fixed on a wooden pallet, which is connected in series at exactly 3.6 volts, which is equivalent to a battery pack of three dry batteries in later generations. In addition to stirring it from time to time when using, Sun Yi is very satisfied with all other performances.

Sun Yi's power bank and flashlight were resurrected with full blood, and Sun Yi felt that he was also full of energy again.

The only displeasure is that you can't shave. At the beginning, in order to reduce weight, Sun Yi did not bring any equipment that he could bring when he went to Wolf Mountain Flying Birds. The people of the Ming Dynasty did not have the habit and tools of shaving, so Sun Yi simply began to grow beards and grow hair like the people of the Ming Dynasty.

In a clay pot that Little Pomegranate was in charge of, Sun Yi generously dissolved a lot of precious alum. This crockpot is actually Sun Yi's electrolytic copper device. Six tin cans form a 2.4-volt battery pack, and the two battery packs are connected in parallel. Twelve iron pots powered two copper coins hanging in a blue alum solution, the copper coins at the anode were constantly corroded, and the copper coins on the cathode were constantly hung with pure copper precipitated from the blue alum solution. Now the anode copper coins have been replaced, and the eyes of the cathode copper coins are almost covered by the plush pure copper.

The purity of copper obtained by electrolysis can reach 99.99%, and this electrolytic copper is used in later circuits and wires. And Sun Yi currently uses the soil method to screen out the "pure copper coin", and I don't know how many strange impurities it contains.

Next to the electrolytic copper crockpot, there is another similar crockpot that the pomegranate takes care of. The water in this crockpot is not blue but green, and the electrodes hanging are not copper coins but two iron rods. This is Sun Yi's electrolytic iron device. The purity of the electrolyzed iron can also reach 99.99%. Because pure iron is too soft, it is not of great use in metallurgy in later generations except for making staples. However, 99.99% pure iron is indispensable in electrical circuits.

The green solution in the electrolytic iron pot is the waste liquid of Sun Yi's iron pot battery. Because of the demonstration of the arc, many iron tank batteries have run out of power - that is, the hydrogen ions in the iron tank are exhausted, and the mixed acid becomes an iron ion solution dominated by ferrous sulfate. Ferrous sulfate is alum. Sun Yi concentrated these alum solutions and carried out a serious concentration operation - in other words, they were boiled in a pot like boiling salt, and then went to eat, and when the water in the green alum solution had almost evaporated, the color changed from a pale cyan to a blue-green.

Although the output of the two electrolytic crockpots is low, it can finally solve the problem of whether there are high-quality circuit materials in the future.

Ming Dynasty craftsmen were particularly interested in lightning. They quickly concluded that there was no "small lightning" when the two copper wires of the battery were separated and turned into contact, and that there was a chance that there would be "small lightning" when the two copper wires were separated from each other.

Sun Yi was just surprised that the Ming Dynasty people could enter the professional field so quickly, and the Ming Dynasty people came to a second conclusion: "lightning" can be produced with copper wires and iron rods, but not with ropes, branches, or even hollow wheat straws that lead water!

The rope and branches are not connected to electricity, and the people of the Ming Dynasty can still figure it out, but the hollow wheat straw can't lead to electricity, so it shouldn't be, and the wheat straw is clearly hollow!

When the lawsuit came to Sun Yi, Sun Yi was just perfunctory: "Electricity is not water after all, some things can conduct electricity, and some things don't, you can try it yourself." ”

On the contrary, Jia Daoshi gave a very clear explanation: "Electricity is born from gold, so gold is the mother of electricity." Electric love mother, refusing to leave her mother. ”

So the craftsmen of the Ming Dynasty found all kinds of strange gold things to experiment, and found that what Jia Daoshi said was very reasonable.

In this regard, Sun Yi just let it go.

When Volt invented the battery, he insisted that electricity could be generated as long as any two metals came into contact. Science is like that, it's about trial and error, it's about making progress.

Therefore, Sun Yi preferred to let the Ming Dynasty craftsmen try it themselves, while he himself had more time to walk around the woods camp and take a turn, and stay with the baby more.

In the camp, the Wolf Mountain Hall has been in the limelight for the past two days.

Since the opening of the mountain hall, the robe buddies have hung out a big disguise, and a huge five-pointed star has been hung on the disguise. The robe buddies said that this is called the five-pointed star with the edge exposed, and it was painted by Lord Lideer himself.

The robe buddies don't care about how to divide the production team, nor do they worry about farming, they gather under the pentagram on time every day, either take off their shirts to learn skills, or point and ponder the meridians. A dragon sits under the pentagram with a pot of tea until the evening at dawn, and is called "sitting in the hall". There was a public security incident in the camp, and before the people of the Iron Supervision Army arrived, the heroes had already settled down. There are also a lot of trivial matters of mothers-in-law and mothers-in-law who can't interfere with the iron prison army, and the heroes all "politely" invite the parties to "drink tea and make sense" under the pentagram. Many heroes have made a wooden five-pointed star card to hang around their necks, not to mention flying on the road, there must be a high toe.

There are people in the camp who have hot eyes, and they want to join the Wolf Mountain Hall, but they don't accept it, so they have to be introduced.

There are also those who are angry, and they dare not offend these people. This group of good men and brothers in robes are commensurate with each other, and if you offend one, more than a dozen of them can come in a blink of an eye to invite you to "drink tea and make sense".

So a group of eye-catching croppers and craftsmen hung a wooden Tai Chi Yin Yang fish under the big catalpa tree. Wang Erniu said that this is called yin and yang, endless, and it was also painted by Lord Lidel himself.

The division of the people in the camp into four teams has also been completed, and these days they are busy electing their own captains.

According to the plan, the three people's teams will move out of this mangrove forest area one after another. Because although this land is a good place to camp in seclusion, it is not conducive to agricultural development. The whole area of the red willow forest is low-lying, full of swamps, shrubs and woods, and there is not enough arable land suitable for large-scale reclamation. The water in the water and the creek is barely visible, which is not conducive to the opening of canals for irrigation and the installation of hydraulic machinery.

However, a large number of military households and their families who have been disarmed and returned to the fields are eager to get land as soon as possible, so they have chosen to stay in Hongliulin. They also named the land "Forest Township".

"Shulinzi Township" then became the team with the largest number of people, and Sun Fall, Yilong and Wang Erniu all nominated their favorite candidates for captaincy. But everyone didn't expect that the last person who was elected as the captain of "Shulinzi Township" was the undead Hu Donkey.

Hu Donkey's condition was miraculously stabilized after several repetitions. Hu Donkey's township party all died in the crops outside the camp, and he did not plan to move to other places to live, so he entered Shulinzi Township. It is said that he is not from a military family, nor is he from Yan'an Mansion, and he has no common people's foundation. But the people were willing to choose Hu Donkey as the captain, just because he only nagged one thing all day long: "When I have an acre and three points of land......
