The first day (5) of the crazy cans
If I can truly live for another 8 years, that would be considered a favor from heaven, and I would be very content
Chicken breast, preserved with preservatives, has a shelf life of two years. Tang Yue then took out a large bag of chicken breast from the box, "Twenty kilograms, which can last for two months."
On Mars, freshwater and oxygen are equally precious; without freshwater, Tang Yue would not survive for more than three days
You, on average, consume 1.56 kilograms of drinking water per Martian day, and the rehydrated food contains approximately 1.20 kilograms of water. To produce oxygen, 0.92 kilograms of water needs to be electrolyzed. Therefore, you need to consume an average of 3.68 kilograms of fresh water each day. Additionally, you need to take a shower once a week, which requires about 5 kilograms of fresh water.
The old cat still dares to say that the soup in your bowl was mixed with Old Zheng's excrement ten minutes ago
One's own affairs are already enough
1200 liters. The old cat replied, "That is also 1200 kilograms"
Tang Yue opened the boxes one by one
I can no longer tolerate this
Similar to large cuts of beef and chicken breast, these large portion ingredients are primarily soft-pack canned foods. These meats have already undergone high-temperature cooking and sterilization on Earth, and they contain a certain amount of moisture. Finally, they are vacuum-sealed using soft packaging. Essentially, they can be considered canned goods, but because they are in soft packaging, they are not as heavy as metal cans and do not take up a lot of space
Tang Yue frowned
The Earth is gone, yet he can still live for another 8 years. Isn't that a gain? Even the King of Hell shows great favor.
Consuming 3.68 kilograms and replenishing 3.4 kilograms results in a deficit. The freshwater in the Kunlun Station will continuously diminish at a rate of 280 grams per day, leading to a gradual decline in the total freshwater reserves. Once the freshwater within the station is completely exhausted, Tang Yue will also be doomed
Tang Yue squatted on the floor, with the maintenance manual of Kunlun Station spread out in front of him, and let out a sigh
The old cat nodded its head
The old cat often tells Tang Yue, the soup in your bowl was mixed with your excrement just ten minutes ago
Tang Yue made a rough estimate, "If we do not consider the quality of life, surely one would not starve to death within a year?"
All wastewater within the station will be recycled, including water vapor, urine, and feces. The toilets at Kunlun Station function as highly efficient suction machines, capable of extracting all absorbable water molecules. Urine is directly dried into urea and uric acid crystals, while feces are dried to the consistency of sand, and then vacuum-packed for transport back to Earth
The oxygen check is complete, and the next thing to examine is the freshwater
Tang Yue took all the large portions of ingredients out of the box and piled them on the shelves and the floor
Calculating at a rate of losing 300 grams per day, this amount of water can only last for... four thousand days
These meats are theoretically safe to eat directly, but their original purpose is for cooking, such as being used as ingredients for frying steak. The permanent population at Kunlun Station is six individuals, and all food is prepared for six people. In reality, twenty kilograms of beef cannot last a week, but now only Tang Yue remains, and he can stretch it to last for two months by tightening his belt
"You yourself are not clear about how much urine you have?" said the old cat, "This is data from the computer statistics, you are expected to produce around 120 grams of feces on average each day"
At Kunlun Station, oxygen and fresh water are produced in a cyclical manner, with both being closely related and working in conjunction. The life support system generates oxygen through the electrolysis of water, and then uses hydrogen and carbon dioxide to produce fresh water
Additionally, your daily breathing and sweating produce approximately 1.6 kilograms of water vapor, while other metabolic activities generate a total of 0.34 kilograms of water. The old cat said, "The water recycling system at Kunlun Station can achieve a maximum recovery rate of 96 percent, which means that Kunlun Station can produce 3.4 kilograms of clean freshwater each day.
In the last supply round, there was still quite a bit of food left, mostly ready-to-eat and semi-processed items. At Kunlun Station, there is no need to eat toothpaste like the early astronauts did; here, there are plates, ovens, and microwaves. Due to the gravity on Mars, there is no need to worry about utensils and food floating around, making food preparation at Kunlun Station much more convenient than on the ISS. The kitchen can almost mimic the design found on Earth.
Moreover, fresh fruits and vegetables cannot be transported at all; it takes a year to travel from Earth to Mars, and anything sent would have spoiled by then
"It is still too early to assert that you can live for another eight years," the old cat bluntly shattered Tang Yue's beautiful dream. "Next, let us take stock of the food."
Tang Yue was taken aback for a moment, "Do I really have that much urine?"
You need not tell me how much I defecate each day; your words make it seem as though I am nothing more than a worthless fecal machine
Beef, vacuum-packed, preserved with preservatives, with a shelf life of two years. Tang Yue took out a large piece of beef from the box and placed it on the shelf, "Twenty kilograms, combined with other items, should last for two months, right?"
Less than three hundred grams of water cannot even fill a five hundred milliliter standard mineral water bottle. If this were on Earth, he would not care at all. Now, Tang Yue finally understands what it means that fresh water is life. This difference of less than three hundred grams will directly determine how much longer he has to live.
"How long will this food last you?" asked the old cat
The old cat nodded its head
How much water do we have left in total
I consume 3.68 kilograms of water every day, but I can only regenerate 3.4 kilograms of water?" Tang Yue asked, "Is there a shortfall of 0.28 kilograms?"
Tang Yue laboriously moved all the packed food out. Food is different from oxygen and water; these items are large, heavy, and take up space. Most of this food was leftover from the previous round and this round's supplies that were not consumed. For some reason, people on Mars have a poor appetite; their taste buds are numb, and even the most delicious food tastes bland in their mouths. Therefore, Tang Yue and the others forced themselves to eat, barely consuming the required amount.
This is merely the most ideal scenario; in reality, it is certain that we will not need four thousand Martian days. At Kunlun Station, you are not the only one consuming fresh water, and as the water recycling and purification system ages, the recovery efficiency will continue to decline. " Old Cat reminded, " I believe that if this water can be used for three thousand Martian days, it would be considered a very ideal situation.
Tang Yue fell silent for a few seconds
Theoretically, the equipment and utensils at Kunlun Station are fully equipped, and there are no technical issues in preparing a full Manchu-Han Imperial Feast. However, in order to conserve water and electricity, most of the food delivered is semi-finished products that have undergone preservation and freezing treatment, requiring only simple cutting and heating to be ready for consumption
a period of eight Earth years
Food is the third essential resource that needs to be accounted for. Inadequate oxygen will cause Tang Yue to suffocate and die, insufficient fresh water will lead to dehydration and death, and a lack of food will result in Tang Yue starving to death
"What about recycling?" Tang Yue asked
Each one is a deadly killer
Old Zheng is one of the members of the expedition team, a greasy middle-aged man whose bowel movements can pollute the air of the entire Kunlun Station, so when he goes to the restroom, everyone else tends to evacuate.
three thousand days
The recycled water primarily comes from urine, feces, respiration, sweat, and other condensate. The old cat replied, "On average, you produce 1.49 kilograms of urine per day"
