Chen Shanhe stopped his movements, his eyes questioning.

Jiang Shiyue: "......"

He bit it all, and now it's too late to say, and the two of them are embarrassed, shaking his head and saying, "It's okay." ”

It's just that my cheeks are uncontrollably hot.

Jiang Shiyue remembered a word.

Indirect kissing.

**

After dinner, the tired Xiao Yangyang slept in the tent, and Jiang Shiyue dragged Chen Shanhe to see the fruits of her day's labor.

You don't have to come to the front to know that the experiment has failed.

The LED lights didn't illuminate the surroundings as Jiang Shiyue imagined.

It's still pitch black.

Jiang Shiyue circled around the tilted telephone pole twice, frowning and muttering, "Why isn't the light on?" ”

After basking in the sun for half a day, coupled with a small windmill, even if the stored electricity is discounted, it can be illuminated for a few hours.

Chen Shanhe handed the lantern to Jiang Shiyue, jumped from the spot, and climbed up the telephone pole with his hands and feet.

The area they rescued was so badly affected that the flashlight battery had been depleted yesterday since the earthquake began.

Fortunately, a batch of candles was turned out in a collapsed supply and marketing cooperative, which could be used for lighting.

When it was windy outside, everyone used cellophane and wooden boards to cover the lit candles and make them simple lanterns.

It's not as bright as a flashlight, but it's better than no light at all.

Jiang Shiyue worked hard to raise the lantern to illuminate Chen Shanhe.

"Who has a flashlight that can light up? Or batteries will do. ”

An anxious voice came through an old-fashioned loudspeaker.

Jiang Shiyue turned her head.

Actually, you can't see anything.

The candlelight in the ruined walls is like fireflies, which can be seen brightly, but the range of light is limited.

"Everyone who still has a flashlight that can be used bothered to be sent to the surgical tent. Emergency! ”

"Repeat, whoever has a flashlight or a battery for a flashlight bucket should send it to the surgical tent."

Jiang Shiyue subconsciously raised her head.

Chen Shanhe happened to bow his head, and the two of them looked at each other in the faint candlelight.

Chen Shanhe spoke: "If you are ......" He pointed to the LED light he had never seen before and asked Jiang Shiyue, "If the light is on, can there be a surgical light?" ”

Jiang Shiyue shook her head, "It's different." The lights used in surgery must not only be bright, but also shadowless. There will be a shadow of this LED light, I don't know if it can be used. And ......"

Jiang Shiyue sighed lightly, "I'm a layman, I haven't studied it, this experiment has failed, and the lights are not on." ”

The loudspeaker continued to shout, proving that the situation was indeed urgent.

However, 78 years were limited in all aspects, and it was an epic disaster.

From the first second of Jiang Shiyue's arrival, there will be regrets in every second.

Often a second late, a living life is lost.

Jiang Shiyue got these materials in order to go back to his hometown with Chen Shanhe to pass the time and solve the electricity problem at the same time, who would have thought that he would be intercepted by the earthquake halfway.

She remembers that in her previous life, she made two-kilowatt solar panels, which could collect 10 kilowatts of electricity a day when the sun was good.

However, that is thanks to the fact that the battery technology is advanced enough.

A battery is a device that can convert chemical energy into electrical energy and convert electrical energy into chemical energy.

In Jiang Shiyue's last life, there have been many kinds of batteries for energy storage, including lithium iron phosphate batteries, polymer lithium batteries, ternary ion batteries and lead-acid batteries, the originator of batteries.

It is now 78 years, limited by the development of science and technology, the battery materials prepared by Lu Zheng for Jiang Shiyue are used for lead-acid batteries.

The standard voltage of a single-cell lead-acid battery is two volts, which can charge 2.4 volts and put 1.5 volts of electricity.

Twelve volts of electricity is six single-compartment lead-acid batteries connected in series, and so on, there are twenty-four volts, thirty-six volts, and so on.

The cost of lead-acid batteries is not high, and Lu Zheng is afraid of Jiang Shiyue's failure, so he has given a full 60 single-grid battery materials.

Jiang Shiyue used the material of eighteen single-cell batteries today, which is only 36 volts.

The solar panels used one square meter of monocrystalline silicon, about 120 watts, and it only took six hours to generate electricity normally today, and a total of 0.72 kWh of electricity was collected.

Less than one kilowatt-hour of electricity.

In addition to solar panels, there is also a small wind turbine, which is a bit far-fetched to say small, but it can be considered miniature.

The wind turbine made by Jiang Shiyue has a relatively small capacity, only 100 watts.

Unlike solar power, wind turbines are also affected by the magnitude of the wind.

According to today's wind strength, at least 0.2 kWh of electricity is an hour.

Adds up to enough to light up a night.

The premise is that Jiang Shiyue's DIY solar energy, wind turbines, and LED lights can operate normally.

Now, apparently not.

Jiang Shiyue looked up at Chen Shanhe, who was busy working at the top of the telephone pole.

Whether it can be lit tonight depends on whether Chen Shanhe can be repaired.

Chen Shanhe tinkered for a while, slipped down the telephone pole, tinkered with the battery for a while, got up, and clapped his hands, "Okay." ”

As soon as the voice ended, the LED light at the top lit up.

In 78, it was still the main tungsten light bulb, and suddenly such a bright white light came down, Jiang Shiyue's eyes were a little uncomfortable, and she raised her hand to cover her eyes, with a look of surprise: "How did you fix it?" You also know how to generate electricity? ”

Chen Shanhe shook his head, his face was somewhat complicated, "I don't know how to generate electricity, but I know a little bit about circuits." You've got a light bulb from this ......"

He pointed to the battery, "The wires of the big box are reversed. ”

Jiang Shiyue: "......"

The sudden light attracted the attention of many people.

Chen Shanhe pointed to the LED lights hanging on the telephone poles, "Can you take this off and take it away?" Or do you have to hang here? ”

If you have to hang it here, do you have to move the surgery tent here?

"You can take it away, you don't have to dismantle it all, you just need to dismantle the battery and LED lights."

Chen Shanhe nodded, turned off the power, and climbed the tree again.

"Huh? How did it go out? Panting and doubtful voices rang out not far away.

Jiang Shiyue carried a lantern to shine at the source of the sound.

A bloodied man with his hands on his knees, looking up at the top of a telephone pole, his confused face showing despair.

It's just that it is illuminated by the hazy candlelight, and the vision is very impacted.

Jiang Shiyue knew that the other party was human, but she was still frightened, so she couldn't help but take a step back, and the lantern in her hand almost fell to the ground.

The man hurriedly turned his back, "I'm sorry, I'm scared of you." I was in a hurry and didn't bother to wash my face. ”

Jiang Shiyue shook her head, shook her head halfway to realize that the other party couldn't see, and hurriedly said, "It's okay." Comrade, is there something wrong with you coming here in such a hurry? ”

Hearing this, the man turned around again, and looked up at Chen Shanhe working on the telephone pole with an anxious face, "I saw Liang running over here just now." My wife is now waiting for surgery, but the generator in the surgery tent suddenly broke down and could not generate electricity. ”

The one-meter-eight northern man choked up as he spoke.

"My wife...... She didn't die when she was rescued, but she was still pregnant. When she was found, she was hunched over her stomach with her vertebrae crushed, but the child in her belly was fine. "He touched his eyes," said the doctor, who now has a chance to save the child. ”
