Doomsday: Unlimited upgrades to the shelter

Chapter 62 Upgrading to Biomass Generators

Existing solar generators, biogas generators.Generally speaking, it should be a diesel generator.

But now there is a very real problem in front of us. The essence of diesel generators is to need diesel. Diesel itself is a consumable product that needs to be continuously exchanged from the system. Although the efficiency of diesel generators is very high, it is difficult to guarantee that the system will not There will be a sudden convulsion, and if the diesel supply is cut off, the entire shelter will be paralyzed in an instant.

Diesel generator, just skip it.

Next up is the biomass generator.Compared with diesel generators, biomass generators have a lot of advantages, and the raw materials they require are not limited.Although in general, for the sake of environmental protection, some dry combustible materials such as corn stalks, wheat stalks, and rice husks are used as raw materials.

But in fact, all items that can be burned can be used as biomass to generate electricity.Anyway, the end of the world is like this, it is best to increase the utilization rate, there is no need to limit the conditions to death, people are alive.

If combustible items are used, the sources are too extensive, including those combustible losses, which can make them disappear completely, and can also help them generate electricity.

Let’s do this first, and when there are more points later, you can install a purifier, and all the exhaust gas will be filtered and then discharged into the air, so that the sulfur dioxide produced by combustion will not pollute the air.

Xie Yannan has already made up his mind, the next step is to upgrade the biomass generator.In the short term, this generator is really beneficial to them, because it has a wide range of combustibles, and it can also solve the garbage and fallen leaves produced by the valley itself.The power generation efficiency will be more than double that of the biogas generator.

As for the natural gas purifier, it is better to keep it for now, it is indeed much more convenient for cooking.

Heh, a garbage generator is still so expensive.Xie Yannan narrowed his eyes and looked at the generator in front of him. It seemed to be as big as three biogas generators, and a cylindrical storage room was automatically generated next to it.

"Biomass."

The name is simple and elegant, isn't it the garbage room, gathered here to provide fuel for the generator.Now you don’t have to worry about electricity.

Now they only need more than 100 watts per day, and this garbage generator can generate more than 200 watts of electricity every day through combustion.

only……

Xie Yannan looked up at the wisps of green smoke coming out of the chimney at the top of the garbage room, which was a bit of an eyesore.Those are all pollution.

But now the things burning inside are all the mutated eagles that were killed last night.This is good, better than seeing yourself disgusted.

Xie Yannan looked at his new generator contentedly and smiled, and suddenly saw a blue bracelet on his hand, which clearly belonged to Wei Xiaofei.

He felt uncomfortable for a while, but there was nothing he could do. He really didn't want to look for it, not because he didn't love her, but because he was afraid of seeing his favorite girl turned into a zombie.And now he has a little sister by his side, and he has to protect her.

Hey, life is really tangled, what kind of love, what kind of bed, is it not good to fight monsters and upgrade?Isn't farming fragrant?

Depend on!
However, speaking of last night, Feifei was really soft and fragrant...

Xie Yannan held back not to let himself down, and wanted to quickly divert his attention.

It is far from enough to have a simple accommodation in the basement. There must be weapons that can resist the outside world, and it is imperative to build an arsenal.

There are too many plans, but I really have too few points now. It seems that the most important thing is to expand the way to obtain points.

It was night before he knew it, and he curled up on the bed only to find that there was a shallow pool of blood on the lower part of the bed.

Sure enough, last night wasn't a dream... hey...

[Generate 156 degrees today, get 156 points]

[3.1 tons of purified water today, get 3100 points]

【Purify 2.2 square meters of natural gas today, get 2200 points】

【System points have been updated, now 6627 points】

……

"Brother, wake up." Xiaoxiao didn't move as much as before, and stood beside the bed and shouted in a daze.

Xie Yannan turned over and got up in a jerk, she can no longer be as salty as before, starting today, earn points, quickly upgrade and rise!
He took a deep breath to keep himself awake.Walking to the faucet, he took a handful of clean water and flushed his face, giving himself another breath.

After breakfast, return to the research room.Zeng Rui had prepared nine pills a long time ago, including his own, there are eleven pills in total.

This time, his goal is very clear, to buy back a thing that can warn, at least give a reminder before the enemy attacks, otherwise the game will not be playable.

He took the pill and carefully put it in his pocket.

In the past, Xiaoxiao would always hold his arm and make various instructions when he went out, but this time she stood far away, smiled and waved to him and did not come closer.

I don't know what happened to this little girl?All of a sudden, it's strange. I shouldn't have done anything to hurt her, right? !
Xie Yannan frowned, and got on the motorcycle.

It's a smooth journey, even if you want to end the two losses and drag them back to use them as fuel, you really don't want to do anything. In this last days, this broken system is clearly against yourself everywhere. It seems that you still have to rely on yourself.

Xie Yannan successfully entered the Doomsday Underground Mall.The people in the shopping mall surrounded him enthusiastically as before, asking him what he needed.

"I want to buy an early warning robot, do you have any for sale?" When it was time to really need this thing, Xie Yannan realized that although the shopping mall was huge, it was full of basic daily necessities, food, and some crops, etc.

Not to mention the slightly high-tech ones, I have never even seen TVs.There's something wrong with this.

"Robots, no."

"We're not that high-tech here..."

"Why do you want that thing, an ordinary person?"

"..."

Everyone started discussing, as if Xie Yannan's question was unbelievable.

"That is to say, you don't have one here?" Xie Yannan deliberately raised his voice among the crowd.

"No!" It was the woman's voice, and she responded decisively from a distance.It seems that she is not an ordinary janitor, she may be the management of this mall or something.

"Forget it if you don't have one. Is there any steel or something for sale?" If you don't have a robot, you should always allow yourself to build a robot. Anyway, the system can provide processing.

But at least you have to have the raw materials.
