Stone Era: Restarting Civilization

In addition, Pan Changgong also needs some power generation units.

There is no electricity, which is really inconvenient. The lighting at night is fine, and candles can be used instead.

But those household appliances that use electricity are all scrapped.

The power station in the city has been cut off, but Pan Changgong can choose a mobile power supply to electrify his residence.

When Pan Changgong passed by a construction site, he saw that diesel generators basically exist in every construction site, and some large shopping malls, banks and other public places also have diesel generators in preparation.

A diesel generator is a mobile power source, as long as there is diesel supply, it will always generate electricity.

Of course, in order to prevent the diesel generator from breaking down, or the diesel is not enough, other backup power sources are also needed.

All Pan Changgong could think of was solar panels, which he used in his own home. It should be said that most of the residents in the Land of the Rising Sun would use them. The Land of the Rising Sun is a kingdom of scarce resources with many people and little land.

However, the economic strength of the Land of the Rising Sun ranks among the best in the world, relying on the cooperation of resource recycling and high-tech development.

As an environmentally friendly power generation tool, solar panels have a very wide penetration rate in the Land of the Rising Sun.

However, the penetration rate of solar panels in rural areas is not very high, and Pan Changgong needs to collect more.

One advantage of a solar panel is that it has no moving parts and is basically impossible to fail. The only failure is that the panels will gradually age over time.

However, this aging time is several decades, which is enough compared to the human life span of several decades.

After deciding on the plan, Pan Changgong started the car and drove to the city. It took several hours to collect all the things he wanted to collect.

After that, life became very stable and monotonous. Every day, Pan Changgong either worked in the fields or read the books he found

Especially agricultural ones.

Pan Changgong has never farmed before, so he doesn't know how to make the crops grow well, so he can only follow the description in the book and imitate step by step. Now there is enough time for Pan Changgong to make mistakes.

As for the use of fire, Pan Changgong mainly uses gas at present, and can use other people's gas when its own is used up.

Sometimes when cooking, the gas suddenly runs out, and this is the case. Pan Changgong will use the traditional stove.

Although there are hatchets and baskets in the yard, Pan Changgong has not yet made up his mind to chop wood.

Fortunately, there are still enough burning materials. Although there is no firewood, the clothes, bedding, and old furniture of the residents in this village can be brought to burn, and it can be dealt with for a while.

After reading books about agriculture, Pan Changgong went to read books on how to maintain a car, how a car works and so on.

Because there are abandoned cars everywhere on the road, it gave Pan Changgong a good opportunity to combine theory and practice.

Car maintenance is actually not as difficult as imagined, as long as you know the functions and names of the various components inside the car, and you can quickly determine the cause of the car failure.

Then which part in the car is broken, just replace it directly.

There is no need to learn the maintenance method of each part in the car, that is a huge project, and the details in the car maintenance books are not as detailed.

Learning to maintain cars has brought great convenience to Pan Changgong. The pickup truck he was driving once broke down on the way into the city. It's fixed.

In addition, because I understand the structure of the interior of the car. Pan Changgong started collecting as many alternators as possible from the surrounding cars.

Just figure out how to spin up the rotor of your car's alternator, and the alternator's terminals will provide a steady 12 volts of direct current, enough for modern appliances.

In order to pass the boring and lonely time, Pan Changgong also dissected these alternators disassembled from the car, trying to understand their operating principle.

The structure of the diesel generator is too complex for Pan Changgong to replicate. And if the diesel is used up, I don't know how to mine and refine the diesel.

The technical content of solar panels is even higher, and it is difficult to manufacture without complete industrial support.

Relatively speaking, it is the simplest to use an alternator to generate electricity, and it can be used as a backup energy source after diesel generators and solar panels.

After earnestly studying generators and reading a lot of books related to generators, Pan Changgong has been able to independently manufacture simple generators.

And I have a deeper understanding of the generator, knowing that no matter how fast the rotor rotates in the car generator, the current released from the terminal is stable at 12 volts.

But the permanent magnet motor is different. The faster the rotor rotates, the greater the current released from the terminals.

Sometimes when a lot of power is needed, Pan Changgong finds that the car's alternator is not enough.

Permanent magnet generators are relatively rare compared to alternators, but they are not uncommon. Gym treadmills are equipped with permanent magnet generators.

The structure of the permanent magnet generator and the alternator are very similar, and the technical content is also similar. Pan Changgong also quickly mastered it.

Sometimes in order to find supplies, Pan Changgong needs to travel far. In this case, if he wants to use electricity, it is very inconvenient to bring a diesel generator solar panel or the like.

Pan Changgong also collected a lot of batteries, and there are batteries in the car, but the car's battery is designed to allow him to release a large amount of current instantly to start the electric motor, and then ignite the car engine to start the car.

Therefore, the battery of the car is not designed to be continuously discharged. If the car battery is discharged for a long time, it will be directly damaged.

This is the conclusion Pan Changgong came to after several failed attempts.

Rechargeable lead-acid batteries don't have this problem, and they can be recharged for recycling when they run out.

The sources of rechargeable lead-acid batteries are relatively common. The batteries on the battery car are all rechargeable lead-acid batteries.

Pan Changgong also studied it in detail and knew its principle.

Now Pan Changgong, after mastering the technology of generators and batteries, does not have to worry about electricity consumption at all.

With the gradual development of agriculture, Pan Changgong has indeed discovered many problems in actual operation.

The main problem is that Pan Changgong doesn't know the time.

Agricultural planting is very time-sensitive. For example, some seeds must be sown in spring, and some are specific to the detailed solar terms.

If the satellite and the Internet hadn't collapsed, Pan Changgong could check the time with his mobile phone. Now Pan Changgong has to figure out a way to check the time by himself.

Without a mobile phone, the Rolex watch in Pan Changgong’s hands can be identified, but after a year, the Rolex watch broke down, and the Apex watch, Pan Changgong doesn’t know whether the one in his hand is a counterfeit.

The internal structure of the watch is very complicated and precise, and Pan Changgong can't understand it at all, so there is no way to repair it.

As a last resort, we can only return to the original timing method.

Pan Changgong once watched TV documentaries that the most primitive timekeeping methods of the ancients were the hourglass and the water drop method.

If you want to make an hourglass, you need to be able to make glass. Pan Changgong doesn’t know how to make glass for the time being. Even if he knows, he will not make the shape of glass into a shape like an hourglass with two big ends and a thin center. It takes a long time of study and practice.

The simplest is the water drop timing method, let the water drip down from the top, put a bucket below to catch the water, and the scale is engraved on the bucket.

However, this method cannot refine the time to seconds and minutes. The smallest unit is the hour, which can only be used to know what time it is in a day?

The overall year, month, and day are not sure.

Pan Changgong only temporarily used this water drop timing method after the watch was scrapped.

As for the year, month and day, I can only count on myself every day.

Time passed day by day, and it was three years in a blink of an eye.

Pan Changgong has learned a lot during these three years, and farming has been fully mastered.

In addition, Pan Changgong found that his physical fitness has become stronger and stronger in the past three years. I don't know if it is because of the regular farming and the exercise he has gained from working.

The four senses (sight, hearing, smell, taste) are also sharpened.

You can clearly see things thousands of miles away, hear voices thousands of miles away, smell smells thousands of miles away, and taste the specific taste of food, even if it is very subtle. Taste it.

But because he didn't take care of his beard and hair, Pan Changgong now has a head of silver hair and a long silver beard. From a distance, he looks like an old man.

I don't know which dog I kept fooling around with outside, and gave birth to a litter of puppies.

On the other side, among the astronauts who returned to the earth from the International Space Station and wandered to the isolated island.

Yekov Nikitin and Dalia Nikitin have both given birth to two children.

Corny Lee and Shamiel Volkov are also married.

They are far away on isolated islands, and they cannot rely on the rich resources on land. Even if they have a lot of knowledge, they have no way to develop.

Their life is very primitive, and they eat fish caught in the sea and vegetables cultivated from some plant seeds left by the original aborigines on the island, and they all live in thatched huts.

In just three years, human civilization, which has not been taken care of, has undergone earth-shaking changes.

The streets and alleys of the city are full of all kinds of garbage, as well as wild dogs and cats looking for food among the garbage.

The sewers were blocked for some reason, and some low-lying areas in the city formed stinky puddles.

There is also a circle of weeds growing around the stinky puddle.

Even if there are no cars on the asphalt road surface of the cement road, due to the perennial wind and sun, rain and winter frost, etc., a large number of cracks have appeared without maintenance.

Tenacious weeds emerged from the soil under the cracks. I think in a few years, the city roads will be completely occupied by these weeds.

The rough road is no longer suitable for city cars, only pickup trucks and off-road vehicles can pass.

Pan Changgong drove a pickup truck into the dilapidated city. The wild cats and dogs on the road immediately dispersed when they saw him coming.

Pan Changgong has lived alone for three years, and the motivation behind his continued survival in an isolated environment is that he has not found a way to break the petrification and save his parents.

Although the will can still persist, but the body's instinct can't be helped, violated.

Because electricity can be used, Pan Changgong collected TV DVDs, some indescribable discs, and magazines and books.

Parked the pickup truck in a dilapidated gas station, Pan Changgong got out of the car and opened the gas tank of the car, picked up the fuel gun and inserted it into the fuel tank.

The refueling gun also needs electricity. Pan Changgong also installed a diesel generator in this frequented gas station, so it does not affect the use.

The underground fuel pool under the gas station usually stores nearly 30,000 gallons of fuel, enough for a car to travel 1 million miles, so until now, Pan Changgong has not worried about the fuel for the car.

On both sides of the road, after such a long period of time, the oil in the fuel tanks of abandoned cars has become more oxidized and is not easy to use.

The underground fuel pool of the gas station is relatively better sealed, but it is impossible to store it forever.

In the past three years, many large stores have opened their doors. The clothes in the clothing store have not been kept well and have been exposed to moisture. Many of them have become discolored and moldy, and some have been bitten by insects.

If you want to choose clothes now, Pan Changgong can only go to those large clothing stores.

The locations of large clothing stores are usually located deep in the building. Relatively speaking, they have less contact with the outside world. Only the clothes in these places are mostly in good condition.
