Old Dong followed Li Yu silently. The uncle and others next to him looked at him incomprehensibly, as if they were observing his reaction.

Lao Dong secretly thought: Where does the power of the Da Zhangshu base come from? It is so mysterious.

At the same time, my inner curiosity became even stronger, and my heart felt like it was being scratched by a cat.

Li Yu walked to the door leading to the zombie generator hall, and then slowly opened the door.

Squeak——

Because Li Yu was in front and Li Yu was taller, the view inside was blocked.

But there is light inside and it looks very bright.

Although the zombie generator has stopped working, the electricity generated previously has been stored in the battery. When the zombie generator stops working, the battery is automatically activated.

Li Yu bowed, then gave up a position and stretched out his hand in a please gesture.

hiss!

Old Dong gasped, his eyes a little frightened.

Then he took a few steps back.

Zombies, the whole first floor is full of zombies, there are at least hundreds of them at a glance.

Moreover, these zombies are still alive and walking on the machine at this time.

"This..." Lao Dong couldn't say the complete words for a while.

The shock in his eyes was clearly evident.

But soon, he discovered that these zombies were all welded to death on the machine and could not get off the machine, and their entire heads were welded to their heads with an iron shield.

No danger!

Then he plucked up the courage to get closer and observe.

As expected of an electricity expert, he figured out the operating logic of the zombie generator in just a few minutes.

Tsk-tsk exclaimed: "Good! That's great! Generate electricity through zombies, use the kinetic energy of walking zombies to convert into mechanical energy, and then convert the mechanical energy into electrical energy.

The rotation of the chain drives the generator to generate alternating current, which increases the voltage through the transformer and is transmitted to the box-type substation through cables.

It’s amazing. Who came up with such an idea? It’s wonderful.”

He approached these zombie generators, and the zombies on the machines noticed his approach, became extremely excited, and wanted to bite Lao Dong.

However, his arm was cut off, his entire leg was welded to the machine with a steel plate, and his head was also welded by an iron cage. This made the zombie tightly restricted to the machine and unable to get close to Old Dong.

On the contrary, because the walking speed becomes faster, the rotation of the wheel chain behind is accelerated.

It's just that due to a malfunction, it was not converted into electrical energy smoothly.

Li Yu on the side saw Lao Dong squatting next to the zombie generator for inspection, and explained: "He Bing and Zhou Ran accidentally tried to make it. We named this machine the zombie generator."

"This is the main source of electricity for the Da Zhangshu base."

Old Dong stood up and praised: "Others were scared to death when they saw zombies, but no one thought that they could use the characteristics of zombies to generate electricity. They are geniuses!"

Li Yu suddenly approached and asked, "Please continue to check and see if it can be repaired."

At this moment, a cry of surprise came from behind.

"Holy shit, this is okay."

Li Yu turned around and saw Tianshu brought in by He Bing.

He stared at the zombie generator inside with wide eyes.

He Bing on the side said: "This is one of the sources of power energy for the Da Zhangshu Base. It must be kept secret."

Seeing Tianshu also come in, Li Yu said to Tianshu and Lao Dong:

"This is the core secret of Da Zhangshu Base. Let me remind you that you don't know anything after leaving this house. Do you understand?"

The tone was obviously very calm, but both Lao Dong and Tian Shu felt a strong murderous aura coming from them.

They knew very well what kind of person Li Yu was.

Li Yu has said this at this time, which means that if they leak it out, the consequences will be terrible!

Old Dong trembled all over and quickly expressed his loyalty:

"I understand that I won't know anything after I go out, and I will never tell anyone what I saw today."

"Yes, yes, Mr. Li trusted us by letting us in. How dare we leak it?" Tian Shu, who was next to him, also said quickly.

Based on their brief observation, they roughly understood the principle. In fact, the principle is very simple, and it is not that troublesome to make.

The point is this bold idea.

How could ordinary people think of using zombies to generate electricity when they encounter zombies and have no time to escape?

When Li Yu heard the two people's answers, he nodded slightly and said to them: "You guys can see how to fix it. He Bing, Zhou Ran, please tell them about the situation."

He Bing came over, pointed at a broken wire and said:

"The situation is like this. Due to the thunderstorm outside, the wires were short-circuited... In addition, all the zombie generators were connected in series, which caused all the generators to stop operating. In addition..."

With He Bing's explanation and the inspections of Lao Dong and Tian Shu, they gradually figured out the problem.

"It seems that there are three problems now. 1. The wires are short-circuited and aged. This can be solved by replacing the wires.

2. The lightning protection resistor device just mentioned by He Bing needs to be buried underground to avoid lightning damage to the power grid, otherwise it will still be prone to short circuit.

3. Series connection problem. Once a certain zombie generator fails, other zombie generators will also have problems due to the series connection. It is recommended to use parallel connection."

He Bing next to him nodded and said:

"Yes, we have also considered these three problems, so we need your support to help solve these problems."

Tianshu thought for a while and said:

"In fact, there is another hidden danger. The box-type substation transmits the electric energy after the voltage is increased to the collector line. The current capacity of the centralized line is not enough, and it is easy to cause problems later. It must be replaced with thicker cables with stronger conductivity.

.

Moreover, the electrical conductivity of aluminum is second only to copper. Its electrical conductivity is only two-thirds of copper, but its density is only one-third of copper. The density of copper is greater than that of aluminum..."

Li Yu quickly asked: "Do you have this cable material?"

Li Hang, who was next to him, said: "Yes, just a while ago, the Fifth Satellite City collected a lot of copper core cables. There are a lot of them and they can be used."

Speaking of this, Li Yu had some impressions.

It seems that it was Lao Huang and his team who discovered a cable factory buried in the ruins. Later, due to the relatively high points exchanged with the Da Zhangshu Base, a craze for collecting cables arose among the many cooperators.

The old Dong thought for a while and asked: "Is electricity mainly stored through batteries?"

Zhou Ran nodded and said: "Yes, currently it is mainly stored through batteries. Some of the electrical energy generated by the zombie generator is supplied to the Da Zhangshu Base for use, and the other part is used for electrical storage."

Old Dong touched his Mediterranean hair and asked: "What type of battery did you use?"

Zhou Ran replied:

"There is no need to worry about this. We all use common battery energy storage technologies, including lead-acid batteries, lithium-ion batteries and sodium-sulfur batteries. These battery systems can store a large amount of electrical energy, release it according to demand, and provide continuous and stable

of power output.”

Old Dong nodded and continued: "It's good...it's just..."

Then he was about to continue, but he was afraid of hurting Zhou Ran and He Bing's face, so he suddenly stopped.

When He Bing saw this, he said bluntly: "Just say that you are an expert in power systems, and Lao Zhou and I are both mechanical."

"Finished." Li Yu said calmly.

Hearing Li Yu speak, Old Dong continued what he had not finished just now: "

It’s just that the energy storage of a single battery is still somewhat lacking.

There are generally two types of power storage technologies: 1. Battery energy storage: using batteries to store the electric energy generated by the wind power generation system.

2. Hydrogen storage technology: Use electrolyzed water to convert the electric energy generated by the wind power generation system into hydrogen, and then store the hydrogen.

When needed, the stored hydrogen can be converted into electrical energy through fuel cells. Hydrogen storage technology can provide long-term energy storage and rapid release capabilities.

Moreover, fuel cells have high energy conversion rates and low noise.

Therefore, I think there are two ways to ensure greater stability."

........

Then Lao Dong talked non-stop and talked a lot. It was obvious that he was in his professional field. Many professional terms came out of his mouth, and Li Yu couldn't understand it.

But he didn't interrupt him.

Because he saw He Bing, Zhou Ran, Li Hang and others listening carefully.

As they talked, He Bing and the others also jumped in to talk. As they chatted, their expressions became excited.

Li Yu looked at the time. Ten minutes had passed since Old Dong and the others came in, and it was already half past two in the morning.

So he said: "Let me say a few words."
