The mastermind's method is not mysterious, which is to build a space similar to Whirlwind Valley in the city of the capital, and then use the principle of wind power generation to temporarily absorb energy.

This method is just a compromise, the environment of the Whirlwind Valley loses a lot of energy, and the closed environment is more conducive to the use of energy.

However, due to the sturdiness of the building, the release of wind power has also become a problem, and the main brain estimates that this power generation method can use 1% of the energy in the sphere is very good.

Liu Ye thought about it well, the location of Whirlwind Valley was too far away from the capital, and management and protection became a problem. Now moving wind power to the capital city will save him a lot of effort.

But there is too much energy in the sphere, if it can really guide 1% of the building, I am afraid that the whole building will collapse, and there is not enough strong steel to withstand such a large wind, so the main brain finally set the maximum output power at 0.3%.

Even if it is only 0.3%, it is estimated that there will be thousands of kilowatt-hours of electricity attack every day, and the energy supply will increase more than tenfold at once.

All the idle people in the capital city and Haiwei City, about 1,500 people, were gathered together to renovate and build in the air-raid "shelter" of the day.

The all-concrete rigid 'mixed' structure of the air-raid 'shelter' is sufficient for strong winds of level 10 or above, and the underground environment is also very safe, which will not affect other people, nor will it be easily attacked when foreign enemies attack.

In addition, the steel mill was ordered to go all out to build windmills, and 100 windmills must be built within a week.

One by one, the scattered and isolated air-raid "holes" were opened up by drilling tools, reinforced with steel pipes, tightened with cement, and after digging deep underground, 20 windmills with a height of three meters were placed.

The wind power generation in front of me is thought to be the reason for the high wind power, so it is relatively tall, but since it can create strong winds this time, there is no need to make it huge, as long as it is strong and durable.

'Get' the stone platform in Whirlwind Valley, put the ball, and the air-raid 'hole' that was immediately hollowed out and connected turned into another Whirlwind Valley.

The whining wind was whistling and raging, and the ghosts in the air-raid 'cave' were crying and howling. The wind could not be vented, and it collided back and forth on the thick concrete wall, repeatedly reinforcing it.

In order to facilitate repairs, Liu Ye specially placed a switch on the stone platform, which can stop power generation when necessary, and replace and add necessary windmill parts.

Iron windmills with a diameter of three meters are placed on both sides of the ball, and the energy of the ball is vented in no direction. These windmills, which have a mass of enough tonnage, are driven by huge wind power to earn faster than grinding wheels.

These windmills are coarsely made, and many places between the parts are not polished and smooth, and the turning sound is very harsh. Because it is not 'refined' enough, the windmill can only be used for a month at most in such an environment before it is scrapped.

Of course, Liu Ye didn't think about how long these windmills could last, he just wanted to use the electricity generated by these windmills within a month to make better quality windmills and stronger materials.

As long as the materials can keep up, the energy of the sphere is almost unlimited, and the electricity can not only supply the capital city, but also charge the nuclear battery.

Perhaps human scientists have anticipated the possibility of the end times, and have specially added a rechargeable function to the function of nuclear power generation.

As long as wind power generation can continue to develop, then the energy of the metropolis will no longer be a problem in the future.

The 30 windmills that rotate wildly are undoubtedly powerful, and after connecting to the generator set and adding more than a dozen biogas generators in the metropolis, the daily power has reached 1,200 degrees, which is fully capable of supporting the operation of all the equipment in the steel plant.

Of course, although the power supply is sufficient, those old equipment still need to be repaired, but fortunately, these things are difficult to stalk.

Susha's metallurgy and mechanical manufacturing are world-class, and the chips placed in the garbage king's brain also happen to have relevant system information, and it seems that Sushaguo is also preparing to establish its own base in the wasteland.

Under the intentional teaching of the garbage king, the terrier has completed the basic smelting and mechanical courses, and is only short of some practical experience before he can carry out the formal 'operation'.

And after these months of training and sufficient parts 'operation', those people around the terrier have also made great progress, the basic knowledge has almost been in place, and even started the training of their respective types of work.

Among them, fitters, grinders and maintenance workers have the largest number of workmen, because these two are the easiest to train in the current environment, but Liu Ye's most urgently needed turners, millers, blacksmiths and other types of work, because of the lack of tools, can not be carried out.

Now that the energy supply is in place, the more than a dozen discarded 'beds' of the steel plant can be used after their repairs, and the rest of the equipment is also being prepared for use.

With the emergence of so many types of work, Liu Yesuo introduced another 100 intelligent and hard-working workers to train them in the past in the way of masters and apprentices, and strive to get more usable labor as soon as possible.

In this way, the burden of the stalk is much less, and he can concentrate on studying the metallurgical machinery technology in the Tianer system.

Over time, this snowball will get bigger and bigger, and more workers with knowledge of steel manufacturing will emerge, and Liu Ye will be able to carry out higher-level construction.

The first week of the steel plant was undoubtedly 'chaotic' and 'chaotic', and the sudden change made many people confused, and there was no order in the 'chaos'.

Fortunately, Liu Ye once led students to some large factories to practice 'fine' work, and he also has experience in dealing with this situation.

Quickly appoint the stalk as the director of the steel plant, and ask the stalk to select the captain and deputy captain according to the level of ability, and be responsible for the operation of each workshop. The stalk has both general scheduling, and is adjusted accordingly according to the casting situation of the windmill.

With lathes and machine milling equipment, it is possible to perform fine machining, and due to the cooperation of different types of work, the production efficiency is greatly improved.

In less than a month, a brand new 100 windmills were built, and after Liu Ye replaced the original 30 windmills, the electricity immediately rose to the level of 2,000 kWh.

Even if it is supplied for other civilian needs, it will only consume 200 degrees more electricity, and the remaining 600 degrees of electricity can be used to charge nuclear batteries.

There are still a lot of waste nuclear batteries left in Daducheng, and it takes about 1,000 kilowatt-hours for a full charge of micro nuclear batteries, and small, medium and large batteries need to be fully charged by 1,000 kilowatt-hours, which means that three micro nuclear batteries can be charged in five days.

In such a month, it is equivalent to the production of eighteen miniature nuclear batteries. And because of the atomic structure of the nuclear battery, it is almost unlimited in the number of times it can be charged, which means that after a period of time, the nuclear battery in the capital can be used indefinitely.

Liu Ye began to regret some of the discarded nuclear batteries he had thrown away, and he immediately sent people to search the capital and Haiwei to find everything that was left. It's all energy, and energy is life to the capital.

In addition, Liu Ye also plans to buy some discarded nuclear batteries at the next rally, which are reproduced in various cities, and there are many copies of these things, except for being a waste product, I really don't know how to use it.

The steelmaker is on the right track, but it faces another problem, you must know that the current steelmaking plant is steelmaking as the name suggests, that is, it must have raw materials to make steel into all kinds of needed things.

Those raw materials are made from primary materials such as pig iron, but the refining of these materials is not what steelmakers are currently able to do. Scrap steel will run out one day, and the quality of re-refining is not as good as that of the first refining.

That is to say, the capital city currently needs to build a metallurgical chief, and also carry out geological surveys and carry out exploration of various metal ores.

These things are not so easy, geology and mining are interconnected to do this, oil can not be extracted, but metal products cannot be separated from human society.

The mastermind couldn't provide any help, but fortunately, Liu Ye had the Tianer system in his hand, which had preliminary knowledge of metallurgy and mining. Liu Ye extracted it and compiled it into a book, which immediately opened a 'door' to the accelerated discipline of metallurgical mining.

The so-called rapid development means that all other metal-related products are not learned, and only iron ore-related exploration and mining are learned, so as to form productivity as soon as possible.

Even so, the related ones are very complicated, and it takes at least two months to study 24 hours a day. With such a calculation, the fastest batch will be half a year later.

Teaching and training is something that can't be rushed, and Liu Ye can only endure it for the time being.

There are still a lot of scrap steel in the capital city and Haiwei City, and when it is not enough, it can be used to demolish and make a building. The current development of the steel industry, that is, the current situation, cannot be changed in the short term.

Until the steel mill produced a higher standard of windmill material, the power generation for the wind balls was roughly maintained at the current level, and the biogas digester was at the limit of the population of the metropolis and Haiwei.

Faced with this situation, Liu Ye temporarily put aside the problems of energy and materials and began to study the development of gunpowder.

The steel plant will be able to develop its own bullets at least six months later, but gunpowder is also necessary to make weapons. Liu Ye remembers the black fire 'medicine' method of one nitrate, two yellow and three charcoal, and the use of daily necessities to make nitroglycerin is also his old business.

Liu Ye decided to try to make a few iron watermelons from the past anti-Japanese wars to increase the types of weapons in the capital.
