The most bizarre thing in the world is that a seemingly joking statement turns into a serious reality.
Does this feel like someone's **** friend cursed me inexplicably, and then one day someone was surprised to find that this **** friend really became his stepfather?
On that schematic diagram, there are things drawn that look like kites, but unlike kites, the part above the sky looks quite complicated, with a collection plane, an energy conversion system and a voltage-stabilized output. Port, etc. were specially marked by Li Fanyu in small letters.
In an instant, this diagram attracted the attention of people around.
Looking at the simple but not scrawled schematic diagram on the plan, the expressions of everyone present were roughly: (｀?Д?′)!?
Surprised and confused.
The surprising thing is that what Li Fanyu said about using natural energy to generate electricity turned out to be true.
The confusing thing is that everyone can clearly understand that simple diagram, but they still don’t know why.
Han Zhaojun looked at the schematic diagram carefully, and then looked at You Zhongyang next to him awkwardly, "Director You, this seems to be your major. Can you tell us what this thing is?" What principle? ”
In fact, You Zhongyang had already focused all his attention on Li Fanyu when he was drawing the picture.
He scratched the back of his head and said, "The one drawn by Director Li should be a stratospheric power station. The principle is roughly to raise a photovoltaic collection terminal to the stratosphere, and use the stable illumination there to convert light energy into Electric energy, then use this... two thousand five hundred meters long..."
I really can’t continue editing Male Gobi!
You Zhongyang closed his mouth when he said this, thinking so in his heart.
This thing Li Fanyu painted has actually existed in theory for a long time. But things in this world are like this, theory is theory, reality is reality.
Theory can often be catalyzed into reality by technical means, but the theory often turns into a completely awesome thing that cannot be realized even after hundreds or thousands of years of bragging.
After his explanation, Han Zhaojun became even more confused.
"What is the stratosphere?"
As a person who studies Marx’s basic theory, this word is a bit unfamiliar.
"Ahem, the stratosphere refers to an altitude of eight to fifty kilometers. The temperature in this area is basically constant and the air flow is generally stable. In the stratosphere, there is a laminar wind at a certain altitude where the wind is zero. surface. In other words, there is basically no wind and clouds on this surface.”
Han Zhaojun hummed and swallowed back the phrase "What the **** is a constant" in his stomach.
A sense of intellectual powerlessness arose spontaneously at this moment.
Li Fan smiled foolishly and praised: "Director You is very insightful. I call this power generation device the Stratospheric Power Station. The main principle is to take advantage of the fact that there is no obstruction by clouds above the stratosphere and the atmospheric flow is stable. A system that effectively converts light energy near the ground into electricity and outputs it to the ground. ”
"Director Li, I understand the truth. But...how do you send this light energy collection system to the sky and ensure its stability? How can you ensure that the converted electricity is safely transmitted back to the ground?"
Faced with You Zhongyang’s questioning, Li Fanyu picked up a red pencil. Seeing everyone's confused expressions, he decided to do a simple science popularization. While writing and drawing, he said: "Let me talk about the basic idea. Solar power stations are environmentally friendly and sustainable, and there is no energy depletion problem. , because there is no moving mechanical device, it has the advantage of low failure rate. But as you just said, its main disadvantages are in two aspects. One is that building a solar power station requires a large amount of land resources, and the conversion rate is low.
With the improvement of science and technology, the photoelectric conversion efficiency of the latter will become higher and higher. However, the former and latter are bottlenecks limiting the development of solar power generation.
The main innovation point of stratospheric power station technology is that combined with my country's population, small area per capita, and the characteristics of more mountains and fewer plains, we are very restricted in the construction of solar ground power stations, so why not focus on Throw it into the sky?
In the stratosphere, which is about 10-50 kilometers above the ground, it is difficult for clouds to reach this height. The air here is dry, there is very little dust and water vapor, the atmosphere flows smoothly, and there is almost no influence of harmful gases. Building in the stratosphere Compared with ground-based solar power stations of the same scale, the solar power station receives 5 to 10 times more solar energy. Although the sunshine time is shorter than that in synchronous orbit, it is very close to the stratosphere and the ground, the closest point is only about ten kilometers. Electric energy can be transmitted directly using wires, greatly reducing technical constraints. ”
Seeing the expressions on everyone's faces that said "I **** understand, you go on", he chuckled, "And our stratospheric power station is taking advantage of this advantageous place. It is a large-scale stable power plant driven by solar energy. The fan blades, combined with high-altitude balloons, solar cells and stabilized transformers, achieve a power generation efficiency of 30% to 60%, and are equipped with specially-made superconducting cables whose strength can reach 200,000N per cubic centimeter and whose electrical loss does not exceed 1%. , lead it into the underground power grid."
You Zhongyang obviously understood it completely. He said with great excitement: "What a genius idea!"
But then, he questioned even more: "But Director Li, as far as I know, the highest light energy conversion rate of current photovoltaic cells is only 40%. Moreover, I have never heard that I have seen a superconducting cable with a strength of 200,000N cubic meters. ”
Li Fanyu spread his hands and said, "You will see him soon."
"What do you mean?!"
"That's right, we don't have any of these things."
You Zhongyang’s waist flashed.
Li Fanyu threw the pencil on the table, "But, I will turn them into reality soon."
Through the explanation, Han Zhaojun has roughly understood. Seeing Li Fanyu's determination, he hesitated for a moment and finally made up his mind.
"Director Li, I want you to promise me that this thing of yours is not a joke."
"Secretary Han, the power supply system of the New Industrial Zone is related to the future production capacity of Zhengxin. Do you think I am joking?" Li Fanyu answered seriously.
Han Zhaojun looked at him for a long time before finally nodding: "Okay. Director Li, if you can build this stratospheric power station and verify that it can be stably put into use. Then, I will propose to the municipal meeting that the industrial The planning power of the urban power grid in the new district is left to you Zhengxin! ”
Li Fanyu smiled slightly, "In conjunction with the stratospheric power station, there are many other technologies related to street and transportation, urban transportation... Secretary Han, take a look, haha,"
I have been wasting my efforts for a long time, just want a power grid plan?
Ha!
Li Fanyu’s face is harmless to humans and animals.
