The Walking Dead TWD

Zhou Nan thought Karina had done something bad, but when he opened the door, the scene in front of him shocked him!

I saw a zombie walking quickly on a treadmill. There was a circle of iron fences around it, which prevented it from running to the outside world.

Its palms were cut off and its jaw was removed. Its two most deadly means of attack were all destroyed artificially. This made Zhou Nan feel that zombies would actually have a day when their safety would be off the charts.

At the head of the treadmill, there is a small iron cage with a little mouse inside, which keeps squeaking because of being frightened.

The zombie was tempted by the flesh and blood of the little mouse and kept walking towards the small iron cage, but the conveyor belt was high at one end and low at the other. After taking two steps, it would slide to the bottom due to gravity.

In this way, it keeps repeating mechanical movements, and the zombies will never know fatigue!

The conveyor belt is connected to the engine, and the engine is connected to the battery. Zhou Nan looked at Karina and Marcunes in confusion.

"What does this mean? Wasn't it agreed that Karina would do something bad?"

Marcunes shook his head repeatedly: "I told you to look at the good things Karina did! Who said she did anything bad?"

Zhou Nan took off his backpack and handed it to Marcunes: "Here are the nutrient solution Rick needs, and the medicine Paul needs. Do you think everything is correct?"

Marcus glanced at the medicine Zhou Nan brought and nodded repeatedly.

"Everything is right, absolutely right. Now I am 100% sure that I can get Paul out of danger!"

Karina shed tears of excitement: "Thank you, Zhou Nan, I appreciate everything you have done for Paul. I really don't know how to thank you enough!"

Karina also fulfilled her promise to Zhou Nan and joined Zhou Nan's team.

Hannah and Kelly also came over, and Kelly also expressed his desire to join the camp. Zhou Nan naturally agreed to Kelly's request.

Although Kelly may not have mastered any skills, in the apocalypse, people are the most precious resource!

After everyone introduced themselves to each other, Karina's excitement subsided.

"I was thinking about how I could repay you for saving my life, until I saw your diesel generator."

"I see there aren't many diesel reserves here, so I came up with an idea for another way to generate electricity."

"I hope this running generator I made can help you."

Zhou Nan pointed at the zombie, and a vague understanding appeared in his mind: "Should I use it?"

Karina nodded, "Yes, you are right, we are going to use this zombie to generate electricity!"

"Let me explain to you how it works."

"This is a device that converts the mechanical energy generated by zombies' movements into electrical energy."

"Its working principle is mainly based on electromagnetic induction, that is, when a conductor moves in a changing magnetic flux, an electromotive force is generated, which in turn generates an electric current."

"Its structure includes a generator, a transmission, a transmission, a charger and a battery, and an inverter."

"A generator usually consists of a rotor and a stator. The coil inside the rotor rotates in the magnetic field, generating an induced electromotive force, thereby generating electricity."

"The rotating device is used to convert the zombie's movement into mechanical energy. It can be a treadmill, a joystick, or other suitable device."

"The treadmill used here is the same one used for recovery in hospitals. I need the treadmill's tracks and the gears underneath."

"Because zombies have limited movement speed, and generators require higher speeds to generate electricity effectively, the speed needs to be amplified through a gear set."

"So I used a transmission, which can adjust the gear ratio to suit the running speed and strength of different zombies."

"This battery is a lead-acid battery. The electricity generated by the generator can be stored in the battery or directly supplied to the load."

"An inverter converts direct current into alternating current for use by AC appliances."

……

Karina talked incessantly about the fruits of her labor, using some professional terms that Zhou Nan could not understand.

But Zhou Nan understood a professional term: zombie energy!

Hannah looked at Karina with some admiration. She was a top student who graduated from a university and had vision.

Zhou Nan looked at Karina as if she were a monster, and his mouth felt dry.

Combining the tireless zombies with the running generator, Karina is truly a genius!

If the zombie joints are worn out, you can replace them with new ones. If conditions permit, you can also build two more generators.

"How is the power generation efficiency?" Zhou Nan asked Karina again.

Karina shook her head. "The efficiency isn't ideal, but there's absolutely no problem with supplying small appliances in real time."

"For large electrical appliances, perhaps this zombie needs to accumulate more electricity before it can be used."

Zhou Nan nodded: "What about the freezer in the restaurant? Can it supply electricity in real time?"

Zhou Nan brought a truckload of sausages, and there was still a need for the preservation and storage of the sausages.

Karina shook her head and said, "If the freezer needs to be kept in a continuous refrigeration state, then the treadmill needs to be adjusted to a steeper speed. This will keep this zombie in its extreme state at all times."

"In this case, the amount of electricity it generates in one day can probably power a refrigerator for half a day."

Zhou Nan felt very satisfied with the result. After all, it was very good to produce such an effect without consuming diesel.

Zhou Nan plans to store a freezer full of sausages, and smoke and air-dry the remaining sausages.

Zhou Nan didn't know whether it was possible to air-dry or smoke pure meat sausages. He had never eaten or made them before, but it was better to try than to waste them.

Zhou Nan's eyes also changed when he looked at Karina.

This treadmill generator is certainly important, but it is nothing compared to its maker, Karina. Karina is simply a moving treasure, and she must not be lost!

"Sister Karina is so amazing. I want to learn mechanical knowledge from her!" Billy asked Zhou Nan.

The little boy Gobili has been around Karina today and kept asking Karina to teach him some mechanical knowledge.

Jimmy showed enough interest in medicine, while Billy was terrible at it.

But Billy showed enough enthusiasm for this kind of machinery.

Although Marcus also agreed to let Billy learn mechanical knowledge from Karina, after learning that it was Zhou Nan who let the two children study medicine, Karina felt that Zhou Nan's consent should be sought first.

Even Hannah looked at Zhou Nan. After all, Zhou Nan was the actual person in charge here, and his opinion could not be ignored.

"The child's interest is the most important thing, I think it's okay."

"But Billy, you have to study mechanics seriously with Karina. This is your most important task right now!"

After hearing Zhou Nan's words, Billy nodded repeatedly and promised loudly that he would study hard.
