    It was relatively reliable to let Wei Qi do the work. The next day there was a pack team to deliver the things Su Yu needed to Zuo Jiayan.

    Su Yu still leaves early and comes back late every day. He stays in the office in the morning to read materials, and in the afternoon he stays at school to help Zuo Wenfang correct homework. However, these days, Zuo Xiaoqing does it for him. Although Su Yu corrects less homework, it costs more.  He devoted all his energy to teaching Zuo Xiaoqing to learn computers. Fortunately, Zuo Xiaoqing was lively and quite talented in this area, otherwise it would have been a headache for Su Yu.

    Zuo Wenfang personally led the team to Shangyu Middle School to take the high school entrance examination on the weekend. Zuo Xiaoqing followed Su Yu back to Zuojiayan. Su Yu finally completed the light energy collector and battery after working for several nights.

    Early on Saturday morning, Su Yu got busy. He first installed and debugged the light energy collector on the balcony on the second floor, connected the battery, and then switched the home line power supply to the battery. The simple household power generation equipment was completely  finished.

    The light energy converter and light energy collector are integrated together and are not large in size. The light energy collector looks like a miniature satellite receiver with a diameter of only thirty centimeters. When there is sufficient sunlight, it can transmit light in just a few seconds.  The collected light energy can fully charge the battery made by Su Yu. From collection to charging, everything is automatically completed by the microcomputer.

    When Su Yu did this, he was not secretive. Not only his parents knew about it, but Zuo Xiaoqing also watched it from beginning to end and helped from time to time. However, the question never stopped: "Can you generate electricity with this? Is this solar energy?"  A generator, right? With such a small panel, is the power enough for our home? Why haven¡¯t I heard of this thing?"

    When the power was turned on, a new question came: "Brother, what if it is cloudy and there is no sun?"

    Su Yu had no choice but to explain patiently: "The power supply is connected to the battery. When the power is sufficient, this battery can last for more than half a month in our home. Will the nights here be as long as half a month?  As for cloudy days, it is not a problem. As long as there is light, it will not affect charging. This is a light energy collector, not a solar collector."

    In fact, although this battery is very crudely made, its power supply capacity is not bad. Let alone their own family, it can continue to supply the whole village for half a month without any problem, and it is extremely stable.

    The truly mature technology of later generations will naturally not be so crude. More than 150 years later, this technology has become quite complete. However, the collector is not a light energy collector, but a simple solar collector. But this technology  The real milestone is the improvement of batteries, which makes solar power generation no longer restricted by the rules of day and night.

    In the era when Su Yu lived, this kind of power generation equipment had been eliminated by purer, cheaper and more stable bioenergy, but it could still be seen in some backward areas or private field equipment, but it was slimmer and more delicate, ranging from lighting to  The energy output is integrated into a palm-sized panel. To put it bluntly, it is a fully automatic charging battery.

    If an intelligent auxiliary device can be used, Su Yu can now make a battery that will never cut off power as long as there is a light source. However, in order to drive his own intelligent auxiliary device, the prerequisite is to have a quantum biochip in the brain.  Yu stole it from the incubator in the Federation laboratory. It is the most advanced chip in the Interstellar Federation, but the incubator must be opened first.

    Zuo Xiaoqing felt the charging process of the light energy collector at close range. The panel of the collector was arc-shaped, about thirty centimeters in diameter, and was red in color. It looked extremely bright. He didn't know what material it was made of.  Like countless small particles spliced ??together, both the front and back sides are uneven.

    The moment it was connected to the battery, the red indicator light on the battery panel began to flash, indicating the start of charging. The red arc panel of the light energy collector suddenly dimmed, and the color quickly deepened. In just a few seconds, it went from red to red.  The color turned to dark purple, and the light in the room seemed to encounter the fine iron sand of a powerful magnet and was directed towards the light energy collector.

    The originally blazing sunlight on the window also dimmed at the moment when the color of the collector panel changed, as if all was extracted by the collector. Even the void outside the window changed from light to dark for an instant, but the process was extremely short, even in the blink of an eye.  Not even that. If Zuo Xiaoqing had been more focused, he probably wouldn't have noticed.

    The indicator light on the battery soon automatically switched to green, and the panel of the light energy collector immediately returned to bright red. Whether it was the window or the room, the light returned to its original state.

    Su Yu explained: "The light energy collector will change color when it collects solar energy. Because the capacity of the battery is limited, the charging time is very short, and the color of the panel will only turn slightly darker. If it is collected at full power, the color of the panel will be  The color will turn to pure black, and all surrounding light will be extracted."

    Zuo Xiaoqing said in disbelief: "Just charge it for a short while, no, a few seconds."Can it be used by our family for half a month?  In this case, who will use public electricity in the future?  "

    Su Yu smiled and said, "Don't worry about these things. That is something that the power plant should consider."

    During dinner in the evening, Zuo Xiaoqing talked about this at the dinner table and said, "Dad, why don't we sell electricity at home and let the people at the electric pipe station drink from the northwest wind!"

    Zuo Gui was moved when he heard this and asked Su Yu: "How many households can this solar generator you make support?"

    Su Yu said: "Of course it's no problem to provide Chashugou for us, but if the distance is too far, it will be difficult, because we don't have transformer equipment, and the voltage is not enough to send electricity over long distances. Besides, our family is not short of that money, right?  ?¡±

    Due to the lack of labor, the land allocated to the family was rented to others for cultivation. In addition to paying the agricultural tax, they were only given 100 yuan per mu of land. The family's various expenses have been basically supported by Su Yu these years.  of.

    In addition to Zuo Wenfang and Zuo Xiaoqing's tuition and fees, and Zuo Gui's hospital treatment expenses, Su Yu also remitted 500 yuan to Zuo Wenfang and Zuo Xiaoqing each month, and 1,000 yuan to their families. After Zuo Wenfang graduated from university, she  My share was transferred to my family, which became 1,500 yuan a month.

    This time Su Yu returned to Weiyanping and gave Jian Xiaobu 20,000 yuan directly. There was no need to remit money separately in the future. So when Zuo Xiaoqing said he was selling electricity, Su Yu was a little stunned and asked Zuo Xiaoqing: "I don't have enough money to spend in school."  Didn¡¯t I listen to you?¡±

    Hearing this, Zuo Xiaoqing coughed loudly twice and said, "Where are you going? I just feel it's a bit wasteful"

    Jian Xiaobu glared at his daughter: "Are you asking your brother for money again?"

    Su Yu hurriedly said: "No, Mom, please stop guessing. Well, I did this just to keep the power outage at home. I didn't want to make money with this thing. Besides, our township has less than 4,000 people in total."  , and there are no large-scale electricity facilities, and electricity can¡¯t be sold for much money, and it also causes red eyes.¡±

    Zuo Gui said, "Does it cost a lot to make this thing?"

    Su Yu thought about it and knew what Zuo Gui was thinking: "Of course it's big. Otherwise, wouldn't you be dissatisfied that the streets are like this? Maybe someone has been selling this for a long time."

    Sure enough, after hearing that the cost was very high, Zuo Gui stopped asking this question. Youdao is like a mountain across the road, let alone Zuo Gui, who lives in an extremely closed environment?  I really thought that the gadget Su Yu made was nothing rare.

    Zuo Xiaoqing naturally didn¡¯t believe it. If that were the case, wouldn¡¯t the hydropower stations in the village have been eliminated long ago?  But she was afraid that her mother would question her about her reckless spending and expose Su Yu to her face.

    What made Su Yu very speechless was that after the hydropower station had another power outage that night, another household in Zuojiayan was connected to Su Yu's power the next day. Two days later, one hundred people in Chashugou  Many households have all been connected to their electricity.
