"Green Olympics, High-tech Olympics and People's Olympics" are the three concepts of the 29th Beijing Olympic Games. One of the biggest differences between this Olympic Games and previous Olympic Games is that scientific and technological achievements are widely used in competition equipment, clothing and training means. Make the high-tech Olympics a strong support and reliable guarantee for the green Olympics and the people's Olympics, make the Beijing Olympics a high-tech sports event, and promote the wide application of high-tech achievements in people's lives. During the Olympics, I sat by the TV every day, watching the Olympics and paying attention to the style of Olympic athletes. At the same time, I am also very interested in applying scientific and technological achievements to the competition. For example, the electronic terminal timer can make the athletes rank at a glance; The carbon fiber pole used in modern pole vault is flexible and firm, and it can also prevent the pole from breaking or kinking. All this makes me feel very novel, and I have a strong interest in science and technology to create life, change life and beautify life. Therefore, in daily life, I pay special attention to observation and thinking, especially love reading science and technology books, and want to let science and technology change our lives through my own hands. One night in autumn, my mother and I were walking home from school together. At this time, it was getting dark and the street lamp suddenly lit up. Brought light to the dark road. I looked up at the street lamp curiously, and suddenly I found a flat device above the street lamp, which was tilted to the south. This confuses me. I had to ask my mother, and she told me that it was a solar street lamp. Flat panel devices store solar energy during the day and release energy at night to convert it into electric energy. Ah! It's amazing! How much energy will be saved for the country by replacing electric energy with solar energy! As we walked, I looked at the solar street lamp and was ecstatic. Suddenly a strange idea flashed: If this kind of solar cell can rotate with the sun and capture the light and heat of the sun at any time, wouldn't it store a lot of solar energy? At that time, the brightness of street lamps will be improved a lot, and people will be more convenient to travel at night! I told this idea to my mother, who praised me as a good boy who loves to observe and think, and encouraged me to try it myself. I was very happy ... when I got home, I told my father what I thought, and my father supported me. After the discussion of the whole family, we decided to apply my idea to the "solar boiler" and improve the solar water heater so that it can rotate. It can rotate left and right, and it can also rotate back and forth, all of which require the adjustment of the boiler itself, so as to ensure that the "solar boiler" forms a 90-degree height angle with the sun from beginning to end, so as to maximize the intake of the sun's light and heat, capture the sun's light and heat anytime and anywhere, and solve the problem of heating in winter. After having a preliminary idea, I soon carefully considered my design scheme and made it. In the process of making, I encountered many difficulties. Thanks to my father's "friendship sponsorship", my model of "solar boiler, an alternative product of coal" was finally completed. I'm so happy! Of course, my design is not perfect, such as the front and rear angle rotation of solar boiler. I also participated in the Changping District Science and Technology Innovation Competition. How I look forward to the result of the game! The 29th Olympic Games, which attracted worldwide attention, was a complete success. It not only brought me a pleasing game, but also made me feel the importance of technology in my life! I hope my invention can be widely used in the future! I will continue to make in-depth research and improvement on this invention, using a "solar boiler" to store electricity, and applying the electricity to household appliances such as refrigerators, televisions, computers, air conditioners and electric lights. I hope that the solar boiler I invented can also be used in factories in the future, so that we can solve the problems of coal resources, natural gas shortage and power shortage, and let solar resources better benefit future generations!
