Stone Era: Restarting Civilization

There is already oil, and the oil in the Sagara Oilfield is enough to travel from the Land of the Rising Sun to the beautiful Jianzhou in South Asia.

The combustion rate of oil is much higher than that of coal, and relatively, when the world order is still normal, the price is also much higher.

If the steam engine is invented, it usually burns coal, and burning oil is simply too much money, but at this time, I can only choose this extravagant method.

But in order to avoid waste. And to make oil burn longer, charcoal is also necessary. Combusting oil and charcoal together can burn longer, and the temperature will also be more intense.

In addition, charcoal has another function, which is to purify water.

This time, from the Land of the Rising Sun across the Pacific Ocean to the beautiful Jianzhou in South Asia, no one knows? What will happen on the way or after arriving at the destination?

If the water resources at the destination are all turbid muddy water, a purification device must be used at this time.

The method of purifying water is actually very simple. Take a wooden barrel, open a small hole in the bottom of the wooden barrel, and then spread a layer of charcoal on the bottom layer, and alternately lay fine sand and gravel on top of the charcoal.

Then pour the water into the bucket

The water in the wooden barrel will eventually pass through fine sand, gravel and charcoal and finally flow out of the small holes. At this time, the water has been filtered and basically very clean.

But this is just to filter impurities, there is no way to filter those germs and microorganisms.

The next step is to disinfect. When the world order is still normal, it is very simple to buy bleach or disinfectant.

In this case, a more environmentally friendly and time-consuming method can be used.

Put the filtered water in a glass bottle, then put it in the sun, and use the sun's ultraviolet rays to kill germs.

On a sunny day, as long as you tell it in the sun for six hours, you can complete the disinfection

If it is cloudy or rainy, even if it is cloudy and sometimes sunny, don't try to disinfect, wait until it is sunny, because this disinfection method must be continuously exposed to sunlight to achieve the purpose of disinfection.

The experience of making charcoal at Pan Changgong is quite sufficient.

There is now a lot of charcoal in front of Curry in his warehouse, and these charcoals have helped his subordinates survive this winter safely.

To make charcoal, it is best to use ash and willow.

Because both of these trees are fast-growing trees.

After cutting them down, their roots will grow again directly on the stump.

Moreover, it usually takes five years to grow back into a small tree, which can be cut down again and used as firewood and charcoal.

Although other types of trees can also be used to make charcoal, they are not very good for the environment because they are not fast-growing trees.

Fast-growing forests such as ash and willow can produce 5 to 10 tons of wood per year for processing from just one hectare.

In addition, Pan Changgong didn't know what kind of enemy he was about to face, thinking that the opponent might have a lot of petrochemical weapons.

Pan Changgong felt that it was necessary for him to create an arquebus.

The design range of the matchlock gun can reach hundreds of meters. If the island expedition not long ago invented the matchlock gun, there is no need to use any tricks, just hold the gun and push it horizontally.

This is just doing his best, and Pan Changgong doesn't think he will be invincible after he has a gun.

You must know that the real disaster that happened more than 3,000 years ago petrified all mankind in an instant.

Some people were petrified even indoors.

That is to say, the light of petrified light can penetrate solid

However, it is certain that not all solid substances can penetrate, otherwise, the mastermind behind the scenes will be petrified.

While Pan Changgong was preparing various materials, he also had to do experiments to see if he could find a material that could resist the petrified light, and then make it into a shield to block it, so that it would be invulnerable.

Having said that, the preparatory work has basically been explained, and the remaining three things have to be done by myself.

One is about electricity consumption.

Now the shops in the village of Pan Changgong all come from waterwheels, and the water flows to drive the waterwheels to generate kinetic energy, so that the generator can rotate and release electricity.

This method is obviously not suitable on a moving boat.

There are relatively strong winds and waves on the sea, and wind energy can be used to generate electricity.

That is to make a windmill, the principle is the same as the waterwheel, as long as the windmill is blown and rotated, the gears under the windmill are driven, and then converted into kinetic energy to turn the generator.

The scale will definitely not be very large, but it should be enough for everyone on the ship to use.

Also, Pan Changgong is ready to make candles.

In the absence of a flashlight, candles can be said to be the best mobile light source.

Originally, candles were something I didn't use because I didn't need them, so I didn't make them.

After all, the village has already been powered on, and the lights are turned on directly on the Internet, so you can see the situation in the village directly, and no one will go into the woods in the dark for no reason.

Even if there is such a situation, it is very convenient to make a temporary torch, that is, wrap a circle of plant fibers on a wooden stick, then pour oil on it, and ignite the fire.

But in a boat with a small space, it is too unsafe to use a torch, and it is likely to ignite the boat. A much smaller candle is much better.

Small candles have a very simple structure on the surface, nothing more than paraffin wax and wicks.

The invention of candles has a history of thousands of years. However, modern candles have only been invented for 200 years.

The candles before this were completely different from the candles you see now.

The wick of an original candle is a very thick fiber.

Because it can burn very long in this way, but it has a defect, that is, as the flame burns, the paraffin will burn less and less, but the wick will become longer and longer. Although the wick that is too thick can make the flame burn It is more durable, but there is a trouble, that is, the wick must be trimmed constantly, otherwise the flame will become smaller.

However, the wick of modern candles is flat and thin. The reason for this design is that this type of wick will automatically curl when the flame burns, and the excess part will be completely burned off. If it flows down, there is no need to cut it all the time.

As for the candle body that makes up the candle, most modern candles are made of paraffin, which is a petroleum compound. Now I have obtained petroleum, but unfortunately I really don't know how to make petroleum into paraffin.

Fortunately, there are other alternatives, such as beeswax, which can be made by bees.

You can also directly refine animal fat to make candles.

However, candles made of animal fat are also very particular. You must not choose pork fat, because pork fat smells bad when it is burned, and the smoke is relatively heavy.

Cattle fat and sheep fat candles are much better.

Pour the melted animal fat into the mold, then dip the wick into the uncooled hot fat, and let it cool to set, and it's done.

The last, and most important thing to prepare for, is the.

Radar can be used for positioning and navigation, and can also be used to detect invisible seabed conditions, to avoid the ship from hitting the rocks, and to know which area has more fish, which is also very helpful for fishing.

During the long sea voyage, it is estimated that there will be a lot of fish meat. In order to improve the efficiency of fishing, it is necessary to make radar, otherwise it can only rely on luck.

However, the production of radar is very complicated, and it really cannot be completed in a short while.

Pan Changgong walked out of the laboratory, ready to relax his tense brain, and just after a stretch, Pan Changgong noticed that Liuli and Amber were sitting in front of the door of their own house, as if they were talking to each other.

Amber's expression didn't look very happy. Three. .
