My Black Tech Shelter

On the morning of May 30, Lu Chen got up and started preparing to build a biological oxygen generator. Different from industrial oxygen production equipment, industrial oxygen production uses physical methods to produce oxygen, while biological oxygen generators use algae to produce oxygen.

We know that oxygen on the planet is produced by photosynthesis of plants, and both plants and cyanobacteria can produce oxygen.

Tropical rainforests are called the lungs of the planet, but the organic matter produced by tropical rainforests is quickly consumed, producing a large amount of carbon dioxide, so the oxygen output of tropical rainforests is almost equal to consumption;

Due to the cold, the organic matter of plants in the cold zone will not be consumed in large quantities, and will release less carbon dioxide and provide us with more oxygen.

The ocean occupies 70% of the planet's surface, and algae are distributed in it to provide us with a large amount of oxygen. Therefore, the biological oxygen generator uses the ability of algae to produce oxygen (personal understanding, if it is wrong, it is a parallel world, and the biological laws are different. Bar).

Later, Lu Chen came to the workshop and first made a large box with a length, width and height of one meter, and then placed five layers of partition boards inside. Then the partition board was sealed with a piece of glass, and the cover of the water tank was covered with a blower. , there is a sun lamp hanging on it,

Then Lu Chen left the shelter and went to a river, fetched a basin of water, returned to the shelter and poured it into the box, then poured the water inside the shelter, and then closed the cover. There is a pipe on each side of the top,

This is used to connect to the ventilation system of the shelter. It takes air in and out at the same time. The outlet section is connected to the air conditioning and ventilation system. The air inside the shelter is sucked in through the blower, and sent into the air conditioning system through the pipe and then blown into the shelter. Therefore, forming an internal small loop,

Because you don’t have a culture medium, you can only use substances in the water to cultivate algae, so you need to change the water regularly.

Lu Chen used the nanocore to calculate that if the algae in the biological oxygen generator were completely cultivated, it would be able to ensure the oxygen needs inside a shelter of 10 people.

You only need to change the water once a week. If you are able to make the culture medium yourself, you can just add nutrient solution directly to it, and the water does not need to be changed.

At the same time, while Lu Chen was making a biological oxygen generator, the authorities were also taking action. With the efforts of manufacturing plants in various places, large-scale equipment was transported to the shelter one after another.

The installation began under the guidance of technical personnel. This equipment is a large-scale industrial oxygen production equipment manufactured by the government. After it was transported to the shelter and installed,

As long as sufficient power is ensured, one large piece of equipment like this can guarantee the oxygen supply for 50,000 people inside the shelter. After all, the oxygen content in the atmosphere has only dropped a little.

There are also plants in the cold zone that are responsible for oxygen supply. While installing this equipment, the officials also used resources to start cultivating cold-resistant plants, preparing to transplant a large number of plants around the shelter after the plants are successfully cultivated.

After all, today's daytime is not the kind where you can't see your fingers. It is equivalent to a cloudy day, but much darker than a cloudy day. This results in a much shorter daily daytime, and the photosynthesis of plants is shortened.

Coupled with the lowering of temperatures, the death of many tropical plants, and the large-scale forest fires caused by volcanic eruptions, the oxygen content will drop. With the current temperature, cold zone plants can still survive for the time being.

Just when the government installed large-scale oxygen-generating equipment, various breeding bases were also equipped with biological oxygen-generating equipment, and they were all large-scale equipment. Some non-toxic and harmless algae were selected for cultivation. Through the cultivation and reproduction of algae, water was provided. and carbon dioxide to produce oxygen,

When there is a lot of algae, the excess algae is dried and made into livestock feed for feeding, and the animal excrement can be made into fertilizer to fertilize the planting base, forming a circular chain that ensures the supply of part of the rations and meat. .

Here, Lu Chen took a look at the finished biological oxygen generator. After plugging in the power, he turned on the sun lamp and let the algae inside reproduce on its own. It was estimated that it would be ready for use on the day of the transaction.

Then Lu Chen went to the forum, contacted Xu Jian, and asked him if he wanted oxygen-generating equipment. Xu Jian had also learned about the drop in oxygen in the past few days, and was worried about it. He did not expect that Lu Chen would make oxygen-generating equipment. He was immediately overjoyed and started working with Lu Chen. After some haggling, Xu Jian paid 1 ton of sand and gravel, 500kg of cement, and 1 ton of metal in exchange.

After confirming the deal, Lu Chen came to the workshop and finished the second biological oxygen generator. Then he looked at the nanocore and found that the high-energy battery deduction had been completed.

Lu Chen began to check out the high-energy batteries launched this time and found that the launched graphene lithium battery was added with graphene technology. The charging time is 1,000 times faster than ordinary lithium batteries, and the energy density is also higher than the original lithium-ion battery. five times higher,

Lu Chen was still a little disappointed when he saw this. After all, he thought that a higher density battery could be derived.

"Sure enough, when I was told that I only needed 200 points of energy, I should have thought that there wouldn't be such a big improvement."

Lu Chen felt that he should be mentally prepared when he started the deduction at only 200 points. However, the graphene battery was enough for now. After all, he was only active in this city. He could continue to study when he had enough energy in the future.

Later, Lu Chen looked at the battery manufacturing technology and found that there were a lot of equipment in the introduction below, including the initial input of raw materials to the final battery packaging. The technical principles and equipment were all introduced in detail, including There are also manufacturing technologies for production equipment,

Lu Chen continued to read and found that nanocores can be used for manufacturing. If energy is used directly, it will take about 100 energy points to create a battery. Lu Chen looked at the data

——

Graphene lithium battery

Manufacturing requirements: 100 energy points

Manufacturing time: 15 minutes

Volume: 20cm long, 10cm wide, 5cm thick

Weight: 5kg

Energy density: 100 degrees

——

Lu Chen found that this density is still acceptable. After all, the battery of an electric car like Tesla has about 60 to 70 kilowatt-hours of electricity. This battery has a higher energy density than this, and its volume has also been reduced, and the charging speed is faster. Lu Chen estimated that the power of this single battery would be enough for him to wear protective clothing for more than five hours. When the time comes, adding two more batteries would be enough for him to carry out activities for a day.

Moreover, the weight of the two batteries is only 20 kilograms, which is still light compared to the capabilities of the mechanical power-assist device in the protective suit.

Lu Chen saw that the nanocore had more than 400 energy points, and immediately used 100 energy points to create a battery.

Fifteen minutes later, Lu Chen looked at the freshly baked graphene battery in his hand and felt the greatness of technology. It was incredible that such a small battery could store so much power.

Then, Lu Chen began to use workshop equipment and nano-core to make protective clothing. He used the mechanical assist device as the skeleton and added high-strength carbon fiber fabric to create the main body of the protective clothing.

Then a device was added to the side of the protective suit, which can be used to store small oxygen bottles. A micro oxygen generator was also added to the back of the protective suit at the waist, which uses physical adsorption to provide oxygen. As long as the battery is Adequate supply of oxygen can be ensured.

As for the oxygen bottles on the side, they are used as backup measures. If you are unable to return to the shelter in time due to some delay, then these two oxygen bottles are life-saving straw to ensure your survival.

The battery is located on the back of the protective suit and has a detachable modular design, so if this set of batteries runs out of power, you can directly remove it and install a second set of batteries.

Finally, there is the position of the head mask. After Lu Chen made the head mask, he added a night vision function and a display board function. This display board can see the overall status of the protective suit in real time, including the pressure inside the protective suit. , oxygen content, temperature, etc. to avoid accidents,

In the end, after Lu Chen completed the manufacturing, he spent a total of 150 energy points and several materials, and finally spent 50 energy points to optimize the overall protective suit. What finally appeared in front of Lu Chen was something like the protective suit in Wandering Planet. style.

However, Lu Chen's is more advanced than the one in the movie. First of all, mechanical assistance allows Lu Chen to lift heavier objects. The ultimate strength reaches 500kg.

Secondly, the built-in buffer device greatly reduces the damage caused by falling from a height, and the protective fabric is made of high-strength material, so it is difficult for ordinary knives to scratch it.

Finally, Lu Chen looked at the remaining 100 points of energy, gritted his teeth, and made another battery. Then he put the two batteries on the protective suit. Then Lu Chen put on the protective suit and left the shelter and started walking around the shelter. Performance of experimental protective clothing,

I saw a red figure moving quickly on a road, reaching a speed of 50 kilometers per hour, and jumping up from time to time, reaching a height of four or five meters. Sometimes there was a car on the roadside. , you can see this figure overturning the car directly, looking extremely relaxed.

This figure is our protagonist Lu Chen. After more than an hour of high-intensity testing, Lu Chen returned to the shelter and saw that the remaining battery power displayed on the protective suit was only 70%. If he used the previous exercise intensity, he would still be able to Used for more than three hours,

Therefore, the power of this protective suit can sustain 10 hours of survival needs under normal conditions, but once it is under high-intensity operation, it can only support 4 hours, so Lu Chen is wondering whether to add two more batteries. After all, this battery The size is not big either, and it is no problem to put four pieces in the back.

Then Lu Chen thought about the test just now. When he was moving quickly, a lot of the surrounding information could not be processed. Sometimes when an obstacle suddenly appeared on the roadside, he would not have time to respond, so he had to have a built-in computer.

"But not only the protective clothing, but other parts of the shelter can also be controlled by computers, and it would be best to use artificial intelligence. However, with my current knowledge base, I can't come up with artificial intelligence.

But there is no problem with general smart programs, and I have a nanocore that can make carbon-based chips, and the computing speed will be faster than silicon-based chips. "

Lu Chen thought of this, looked at the time and it was getting late, and planned to rest first and start researching again tomorrow.
