By linking my account to the check-in system, I became a leisurely traveler.

Chapter 247 Another Upgrade: High-Altitude Oxygen Room [First Update!]

Li Younan drove his car to an open space on the outskirts of Xinduqiao Town and parked it. Then he rode his motorcycle to pick up a package and brought back two or three large cardboard boxes.

When Liu Li saw the two or three large boxes, she was practically dumbfounded.

She couldn't imagine how that small mountain bike could tow so many large boxes, but then she wondered, "What's inside these three boxes?"

Li Younan did not explain, but first disassembled one of them, and then opened the tool kit from the chassis to begin modifying the car.

During the renovation, the noise and disturbance were still relatively controllable.

Liu Li watched silently for a while, not understanding what Li Younan was doing. Perhaps she thought that Li Younan would explain it to her once he was done, so she quietly went back to her room to cook.

Today her idea was to make a bowl of spaghetti, and she got busy in the back.

Li Younan is currently in the cockpit.

The Unimog's cockpit is extremely spacious, especially the large space behind the two seats, which is just the right amount of room to accommodate the two pieces of equipment that Li Younan brought.

These are two white devices, no more than 40 centimeters in height, which are diffusion oxygen generators specially purchased by Li Younan.

While crossing Zheduo Mountain, Li Younan had been thinking about this problem – carrying a portable oxygen concentrator with a tube was inconvenient.

Moreover, although Li Younan himself did not care about altitude sickness, his body would indeed feel more comfortable if there was more oxygen.

After waiting for so long, these two pieces of equipment have finally arrived.

Because Li Younan had modified the electrical circuits of the car in front of him himself, he knew exactly where to connect the wires.

The main units of the two diffusion oxygen generators are installed in the cab, while the air inlets are directly connected to the chassis, allowing air to enter from below the cab.

Even when both devices are running at full power, the noise level is only around 40 to 50 decibels. Thanks to the thick sound insulation at the connection between the enclosure and the cockpit, it is practically inaudible in the living area.

As for driving during the day, it doesn't matter much, as the noise is completely masked by the engine sound.

Two diffused oxygen generators were installed and secured, and then pipelines were connected to the living area. Two control ports were installed, one in the cockpit and one in the living area.

The whole process was very quick for Li Younan, taking only a little over two hours.

He dusted off his hands, turned on the oxygen concentrator, and then opened the door to return to the living area.

Each control unit has an oxygen outlet. Li Younan placed his hand on the oxygen outlet and felt an airflow coming out.

Liu Li tilted her head and looked at Li Younan in confusion: "What is this?"

Li Younan saw a mosquito coil on the table, picked it up, and then aimed the burning point of the mosquito coil at the oxygen outlet. Suddenly, the mosquito coil flashed with intense light and heat.

Li Younan removed the mosquito coil, and the intense oxidation reaction disappeared.

"do you understand?"

Liu Li blinked, her face still showing a puzzled expression: "Uh, I don't understand."

Li Younan smiled and said, "It's oxygen. Oxygen is an oxidizer."

"This is called a diffusion oxygen generator. The principle is to draw in air, pressurize it, absorb the nitrogen in the air, leaving a high concentration of oxygen, and then diffuse and release it into the room through pipes to increase the oxygen concentration of the entire space."

Li Younan knew that Liu Li hadn't studied since junior high school. Although junior high school chemistry must have covered this topic, she had probably forgotten most of it by now, so he tried to keep it simple.

Liu Li understood and asked, "You mean... once this oxygen concentrator is turned on, we won't need to insert the tube into our nose anymore?"

Li Younan nodded: "Yes, that's one way to understand it."

Liu Li thought for a moment: "Won't it use a lot of electricity?"

Li Younan smiled slightly. He had naturally considered this issue long ago and said, "Don't worry, there won't be any problems."

The living area of ​​a motorhome is less than 9 square meters. Even with the driver's cabin included, the total volume of the space that needs oxygenation is only 20 to 30 cubic meters.

A device with a flow rate of 1 to 3 liters per minute would be sufficient to meet the needs.

However, Li Younan always designed some redundancy. The two diffusion oxygen generators have a combined flow rate of 5 liters per minute and two air outlets, which can quickly increase the oxygen content in the living area and the cockpit, but the combined power is only 300 watts. When in actual use, the total power consumption is only about 150 watts.

Using two oxygen concentrators alternately can also extend the product's lifespan.

In other words, even if you use the oxygen concentrator 24 hours a day, it will only consume three or four kilowatt-hours of electricity per day.

The vehicle is powered by a 50 kWh lithium iron phosphate battery pack. In fact, based on their experience living in the RV these past few days, Li Younan and Liu Li only use about four or five kWh a day, so the power supply is more than sufficient.

If this oxygen concentrator is added, the daily power consumption will only increase to about seven or eight kilowatt-hours. Even without the generator and solar photovoltaic panels to supplement the power, the battery pack can maintain power for about a week, so there is basically no problem with power.

However, when it comes to the issue of electricity and water... Li Younan glanced at the control center for water and electricity.

Because of the sunny days these past few days, Li Younan turns on the solar panels when the sun is particularly strong, and the electricity still has over 70% remaining. With even more sunny days ahead, the daily electricity consumption will likely increase, and when they head to the snowy area, the sunshine will become even stronger, making electricity virtually guaranteed.

Water consumption was not as high as expected. On average, the two of them used less than 50 liters of water per day, leaving about 70% clean water.

He and Liu Li had been out for a week, using mostly water for showering, aside from a small amount for cooking. However, before setting off, Li Younan emptied the grey water tank, which was quite full.

Li Younan's vehicle did not have a black water tank installed.

Generally speaking, RVs have three types of water tanks: fresh water tank, grey water tank, and black water tank.

The clean water tank, as the name suggests, holds clean water such as drinking water and bath water; the grey water tank holds domestic wastewater generated from washing clothes, vegetables, and personal hygiene, which will not pollute the environment even if discharged directly onto the ground; the black water tank holds sewage formed by excrement, which certainly cannot be discharged directly into places such as parking lots.

In many places, RVs are criticized because the discharge of black water tanks is a major problem. Inconsiderate RV users discharge black water directly and recklessly in places such as parking lots and roadsides. It is conceivable how the reputation of the RV community has been ruined.

After the oxygen concentrator was installed, Liu Li was visibly pleased. She strolled over to Li Younan, stared at the control panel of the oxygen concentrator for a while, then sniffed the oxygen outlet and nodded seriously: "Hmm, it really works. I feel much clearer-headed."

Li Younan's expression was somewhat strange. He then tapped the control panel lightly, and a "beep" sounded, followed by a notification tone: "Device activated."

Liu Li looked complicated, while Li Younan laughed and said, "When we were connecting this device to the AI ​​hub, we temporarily shut it down for a while."

"Ugh, that makes me seem like I'm just being presumptuous."

"Quite cute."

"Huh? What?"

"Haha." Li Younan didn't continue the topic, casually changing the subject, tidying up the remaining packaging boxes and bags from the oxygen concentrator, and then carrying another unopened box to the table and putting it down.

Liu Li asked, "And what is this thing?"

Li Younan revealed a mysterious expression: "This is a toy."

"Toy?"

When the box was opened, Liu Li saw that the so-called toy was a bunch of parts she couldn't understand, including lenses, motors, bearings, and the like.

Li Younan said meaningfully, "This is a laser cannon."

"A laser cannon? You mean the kind in the movies? A laser cannon? You're kidding me!"

Li Younan said seriously, "In principle, this is a real laser cannon, but it's used to swat mosquitoes." As he spoke, he took out the high-definition camera and played with it in his hand.

Liu Li's eyes widened: "A laser cannon for swatting mosquitoes?"

This equipment was a gift from one of his college classmates; it was a hand-rubbed laser cannon that could be used to swat mosquitoes.

The trained AI can identify mosquitoes using a high-definition camera and then instantly fire a laser to burn them.

Because the power is controllable, it will only harm mosquitoes and will not damage the items where the mosquitoes are staying. Optimizing the code and training samples can further eliminate more pests.

The entire set of equipment is very small; after Li Younan assembled it, it was no bigger than a computer host.

This thing isn't very useful in the living quarters; if a few mosquitoes occasionally fly in, a mosquito killer lamp can take care of it.

However, this mosquito laser cannon will come in handy when we're camping outdoors later.

Li Younan said to Liu Li triumphantly, "The world of science and engineering guys is full of such incredible things. You'll see later. This is the romance of science and engineering guys."

After completing the car upgrades, Li Younan planned to drive the car to town to refuel and buy some supplies to replenish the somewhat depleted refrigerator.

Although there was still a lot of food left in the refrigerator, Li Younan had a strange compulsive symptom about this kind of thing—a refrigerator that was packed full and filled with oil gave him a sense of security.

Upon learning of Li Younan's little quirk, Liu Li revealed a satisfied smile, clearly sharing similar feelings.

The two looked at each other in understanding.

pretty good.

After replenishing the supplies, Li Younan then officially began to complete the daily check-in task.

It was already the end of March, and April would be here in two days. Although it had been snowing heavily just two days ago, the weather had become noticeably warmer after the sun came out.

Correspondingly, the number of tourists arriving here seems to have increased noticeably.

Li Younan's first stop was Juli Temple Pass, because it was relatively close to Xinduqiao.

Before long, the off-road RV, carrying freedom and leisure, was slowly and leisurely approaching the Juli Temple Pass.
