Desert Island Survival: A Hundredfold Improvement After Having a Baby?
Chapter 70 Solar-Powered Water Dispenser
It was still dark.
The sea to the east was a pale, bluish-white.
The sea breeze carried a chilling coldness.
Chen Jian pushed up his glasses, which were covered in handprints, and issued his first ironclad order after seizing power on the deserted island.
"Ma Liang, take two quick-handed men to the beach debris area and bring back all the transparent plastic sheets, large plastic bags, and plastic wrap you can find."
"Those who can still stand, come with me to the nearby garbage dump and rummage through scrap metal boxes, empty aluminum cans, and plastic bottles—anything that doesn't leak and can hold water."
In order to survive, they were incredibly efficient.
In less than twenty minutes, everyone returned to the designated smooth beach, panting heavily.
He was holding various pieces of tattered plastic and bottles and jars torn from the cruise ship wreckage.
Ma Liang threw a piece of plastic sheeting still stained with some unknown brown dirt on the ground, his face full of doubt.
"Mr. Chen, what are you doing picking up this piece of junk plastic after all that trouble? Squeeze it a little, you think you can squeeze any fresh water out of it?"
Chen Jian completely ignored his pointless sarcasm and walked straight to the center of the beach.
"Dig a hole." Chen Jian pointed to the slightly damp sand at his feet and ordered Ma Liang and the other two.
Ma Liang was full of resentment, feeling that Chen Jian was making a big fuss over trivial matters.
But tormented by extreme thirst, he obediently knelt on the ground and desperately dug at the sand with his bare hands.
Soon, a standard inverted cone-shaped sand pit, about the size of a washbasin and half a meter deep, was dug out.
Chen Jian stepped forward and had someone rub several plastic bottles against the stone to break them in two. He then placed them in the very center of the bottom of the pit.
Immediately afterwards, he picked up a plastic bucket with a broken edge next to him, walked to the beach, and scooped up more than half a bucket of murky seawater.
Then he walked to the edge of the sandpit and poured the half-bucket of seawater directly into it. The seawater spread out at the bottom of the pit, and the water level was well controlled, just enough to not submerge the plastic bottles in the middle.
"Holy crap! Why did you fill a pit with toxic salt water? Do you want everyone to die even faster?" A family member of an employee shouted, jumping up and down.
Just as this group was on the verge of losing control, the IT department nerd who had been silent all along suddenly slapped his thigh.
"Snap!" The crisp sound startled everyone around.
"Holy crap! Holy crap! I remember now!" The IT guy exclaimed, his eyes red, pointing at the sandpit in front of Chen Jian.
Ma Liang grabbed his collar: "What's wrong with you! What are you remembering?"
"A solar-powered water distiller!"
He was so excited he was almost incoherent. "I've seen Bear Grylls' 'Man vs. Wild'! This is a physical device that uses high temperatures to evaporate seawater and then condenses it to extract pure fresh water!"
Enraged, Ma Liang slapped Zhang Wei on the back of the head: "Since you knew this method, where were you yesterday and the day before when everyone was thirsty! Why didn't you say so?!"
Zhang Wei wailed with a bitter face:
"Brother Liang, can't you be reasonable?! Yesterday I was so thirsty my brain stem shrunk, my stomach was full of acid, and all I could think about was how to go up there and chop that kid Lin Fan up and steal Nongfu Spring water!"
"We're all just office workers, I've forgotten all about those high school physics problems! If I hadn't seen Engineer Chen digging a hole and pouring water, I would never have remembered them!"
Chen Jian listened to Zhang Wei's complaints and sneered.
Sure enough, when people face dire straits and extreme hunger, not to mention their intelligence, even their basic logical thinking ability will be completely excreted like urine.
Only someone as absolutely calm as his wife can maintain her rationality and thus stand at the top of the food chain.
Chen Jian ignored the noisy crowd.
He picked up the largest piece of transparent plastic sheet he had just found and laid it out completely over the half-meter-deep circular pit.
He crouched down and deftly used the surrounding wet sand and heavy stones to press the edges of the plastic sheet tightly together.
After confirming that the entire sandpit is completely sealed and no air can leak in.
Chen Jianzhi stood up and picked out a thumb-sized, exceptionally smooth pebble from the ground.
Place it in the very center of a taut, transparent plastic sheet.
The plastic sheet, which was originally stretched out flat, immediately sank deeply under the pressure of the stones, forming an inverted conical arc surface without any blind spots.
And the lowest point of condensation and dripping of this conical arc surface was precisely aligned with the top of the plastic bottle at the bottom of the pit.
After completing this final step, Chen Jian let out a long breath and patted the rough sand off his hands.
"Zhang Wei has already explained the principle: physical condensation."
Chen Jian and his team made dozens of these devices before clapping their hands and saying, "Alright, now we only have one thing to do."
"Wait for the sun to rise."
As long as the sun shines on it, the seawater at the bottom of the pit will evaporate into water vapor, which will then condense into water droplets when it comes into contact with the cooler plastic sheet above.
The water droplets slid down the slope to the valley in the middle, and finally dripped into the plastic bottle.
Distilled fresh water that can be drunk directly was created out of thin air.
With the combined endorsement of IT guy's popular science explanation and Chen Jian's practical demonstration, the twenty-odd starving office elites on the beach were completely convinced.
They only regretted not studying more survival skills, instead focusing all their energy on making money and flattering Su Qingxue.
Ma Liang and a few other grown men plopped down around the sandpit.
They guarded that tattered plastic sheet like they were worshipping a god of wealth, not daring to blink an eye.
……
The same morning.
The people on the beach below are straining their eyes over a few drops of unfiltered distilled water.
Above them, in the cavern, the wood in the fire had long since burned out, leaving only a few pieces of dark red embers, emitting a comfortable, drowsy warmth.
Lin Fan leaned comfortably against the cubicle, his eyes closed contentedly.
If an outsider looked over, they would definitely think that this "living Yama" with blood on his hands was catching up on sleep.
But in reality, Lin Fan's entire attention was focused on the transparent system panel that was emitting a faint light, which only he could see.
[An intertidal reef area was detected to the southeast, currently experiencing a rare period of low tide.]
[Optimal time window for low tide: 06:15 - 08:30.]
[A large population of mud crabs remains beneath the rocks in this area, having not receded with the tide. Their hiding places are mostly distributed in crevices of the broken rocks and in deep pools at the bottom.]
[Estimated absolute number to be captured: 40-60 (adults). It is recommended to bring large-capacity containers for the cleanup.]
Lin Fan opened his eyes as he looked at the screen full of gleaming gold characters.
Blue crab!
In a typical civilized society, this would be a high-end product with a starting price of over 100 yuan per kilogram in a fresh food supermarket!
On this deserted island where everyone would fight tooth and nail over half a muddy compressed biscuit, what do dozens of plump blue crabs mean?
