Everyone knows that solar energy is one of the new energy sources that is being vigorously promoted. It is mainly used for photovoltaic power generation, and now technological advances have found new uses for solar energy. Solar energy is used in electronic components, servo systems, and solar tracking systems. The energy used to cut and melt sand is just focused sunlight. Using sand instead of resin and sunlight instead of lasers, solar-sintering technology can melt sand and use solar-powered machines – it's almost green. Kaiye spent half a year making two devices. The first device is called a solar cutting machine, and its technical content is not high. Sunlight is concentrated on a plane by a large spherical lens and controlled by a camera system. When the plane moves under focused light, it will cut the plane object like a laser; another device called solar sintering (this process of turning powder into solid by heating is called sintering, in recent years It has become the central process in 3D printing prototype design. By using sunlight instead of laser, replacing resin with sand, melting sand is used to make 3D objects. Kaye used these two devices to conduct a two-week test in a desert in Egypt. The results were perfect. The use of solar polymerization technology to convert diffuse solar energy into cutting tools with the same effect as lasers is indeed a major new initiative in solar energy utilization. However, this technology may still have certain requirements for solar energy resources, and it needs to be carried out in areas where sunshine is particularly enriched. 1M Mini Measuring Tape,Small Retractable Tape Measure,Precision Tape Measure,Tape Measure Scale SHANGQIU CHAOYUE MEASURING TOOLS CO., LTD , https://www.calibrateds.com
