Solar power can not only provide energy, but also bring peace to human beings

 In the second industrial revolution, human beings entered the era of electricity. The basis of human survival and development was transferred from land to equipment driven by electricity. It has been found that electricity can transmit energy to every corner of the world quickly and efficiently, faster than any previous way of transmitting energy. Today, electricity can not only transmit energy, but also transmit information, not only transmit information, but also process information. People can't live without electricity.            However, human beings can't use the lightning in the sky and the electricity on eels. What they need is controllable electric energy, which is converted by means of firepower, water conservancy, wind power, nuclear energy, or directly converted by solar energy. Except for nuclear power, all forms of power generation are ultimately the conversion of solar energy.            Human development depends on the sun.            Wind power generation. It seems that there is no direct relationship between wind power generation and the sun. In fact, it has a great relationship. If there is no sun shining on the ground, there will be no air temperature difference, no air flow, no wind, let alone wind power generation.            Water conservancy and power generation. When the sun shines on the ground, on rivers, lakes and seas, the liquid water evaporates into water vapor, which condenses again, forming rain and snow, forming streams and rivers, and moving the water in the low place to the high place under the action of the sun, it is possible for human beings to make use of the drop of the terrain for hydropower generation.            Thermal power generation. Thermal power depends on coal and oil. Coal and oil are evolved from ancient animals and plants through hundreds of millions of years. They store solar energy. Plants carry out photosynthesis and convert solar energy into their own components. Animals eat plants. After animals and plants die, they form coal and oil under the action of crustal movement. If it continues to burn like this, the billions of years of accumulated solar energy on earth, such as coal and oil, will be exhausted one day.            Thermal power generation is still the main power generation mode at this stage. The maximum conversion rate of thermal power generation is 70%, the maximum conversion rate of hydropower is 97%, and the maximum conversion rate of wind power is 60%. At present, the most advanced solar energy system in the world, its photoelectric conversion rate is only about 40%. It can be seen that the utilization rate of solar energy is still at a low stage.            Everything grows by the sun.            Plants can carry out photosynthesis, and use photosynthesis to convert solar energy into nutrients such as carbohydrates. Animals that do not carry out photosynthesis cannot directly use solar energy. They can only rely on the solar energy converted by plants. Animals and people take plants as their food, and finally they are absorbing solar energy.            The most direct way to use solar energy is solar power generation.            It will take days to decades to wait for the photosynthesis of plants, and then hundreds of millions of years to wait for them to be converted into coal and oil; wind power is not immediately available, and it will take tens of thousands of years to form a tuyere when the conditions are formed; water conservancy power generation is also a long wait, after the topography and the sunrise and sunset of the sun work together, water conservancy power generation can be established Conditions. Only solar energy can be used immediately.            The ancient Westerners thought that the basic elements of the world were earth, water, fire and wind. The ancient Chinese also had the theory that gold, wood, water, fire and earth were the basic elements of the world. People themselves were made up of these five elements. It seems that the development of human beings can not jump out of these basic elements. Isn't the electric energy of modern people derived from these elements.            Solar power will be the safest and most efficient way to generate electricity.            Compared with nuclear power, solar power is undoubtedly safer. If the efficiency of solar power can reach more than 90%, the world will change fundamentally.            Most of the internal struggles of human beings come from the competition for resources, the most important of which is for energy. If low-cost high photoelectric conversion can be achieved, solar power generation will become the mainstream, and human beings will passively receive solar energy to the extreme.            We can imagine that the cars covered with thin-film solar power generation devices are completely self-sufficient. The gas stations on the streets are gone, and the solar cars do not need to be charged when they are used up; the city does not need to lay cables, and the solar panels on the street lamps provide enough power to use; the buildings generally adopt solar power generation exterior walls, which are self-sufficient in power, and there is no outdoor cable in and out No gas pipes are needed for every household, and electromagnetic cookers are used for cooking. The energy comes from the power provided by solar power generation device on the outer wall of the building.            Solar power will put an end to the war, and mankind will have peace for tens of thousands of years.            Tens of thousands of years later, perhaps human beings will give their own destiny to the artificial intelligence human-machine hybrid, realize the transformation from carbon based organisms to silicon-based organisms, and rush out of the earth and into space.
