DE-STAR system operation principle diagram.
According to a team of scientists from Caltech and the University of California, Santa Barbara, the DE-STAR system can not only monitor and destroy asteroids that threaten the earth, but also evaluate the composition of asteroids and provide energy for interplanetary voyages.
According to comprehensive reports, after a dozen hours of rainstorms on the morning of February 15 local time in several states of Siberia in Russia, a small asteroid full of half the size of a football field passed by. The occurrence of two astronomical "disasters" suddenly increased the sense of urgency for preventing the Earth from encountering "uninvited guest" attacks in outer space. Coincidentally, on the day before the meteorite shower occurred in Russia, on February 14, local time, a team of scientists from the University of California at Santa Barbara and the California Institute of Technology announced a novel plan: use solar energy to build a giant laser beam phased Array to monitor and advance the destruction of asteroids that threaten the Earth.
Philip Rubin, professor of physics at the University of California, Santa Barbara, said in a statement on behalf of his team of scientists: “We must use logical and rational methods to discuss some of the issues we face. We need to act in advance rather than threaten. Only when we come to respond passively, avoiding and obscuring is not the way. In fact, we can make a difference, and we must be able to make a difference. So, let's start taking action right now. Let's start small Start with, and you don't need to spend any resources at first."
What Rubin called "advanced action" is an artificial celestial system that they call the "detection and destruction of asteroids unidirectional solar phased array" (DE-STAR). Its basic principle is: use solar energy to construct a huge laser beam phased array. If an asteroid visits it, it can be locked in time and burned.
“The system is actually nothing unusual.†Gary Hughes, a researcher at the California Institute of Technology, said in a statement, “All the components needed for the system are ready, but their size is not as large as we want.†To increase the size may be a challenge - but the basic elements are already there. We can start now."
According to the Hughes team's vision, the scale of the system is very complex, the required equipment is as small as a desktop, the large diameter can reach 10 kilometers, and the performance will increase as the scale increases. For example, the DE-STAR2 system is only 100 meters in diameter, about the same size as the International Space Station. It can push the comets and asteroids that threaten the earth away from the original orbit. The DE-STAR No.4 system with modular assembly may reach 2 At 100 times the number system, it can emit 1.4 trillion tons of energy each day. Within a year, it can melt an asteroid 500 meters in diameter.
The Hughes team claimed that their ideas are also of great value for the development of asteroid mineral deposits and deep space travel. For example, the DE-STAR system can be used to evaluate the composition of an asteroid and infer which rare elements it may contain. The larger DE-STAR 6 system can also be used as a huge orbital energy source. With it, intergalactic navigation does not have to carry. Heavy energy package.
According to reports, the team is currently preparing a proposal for submission to peer review.
Manufacturing Industry Lighting
Industrial lighting is a lighting solution designed specifically for manufacturing environments. In the manufacturing industry, a good lighting solution is essential to improve production efficiency, ensure work safety and create a comfortable working environment.
Manufacturing lighting needs to meet a range of specific needs. First, there are high lighting requirements for factory lighting, because manufacturing environments often require a lot of light to ensure that employees can see details clearly when carrying out assembly, inspection, and other tasks. Second, reliability and durability are key, as manufacturing environments can have harsh conditions such as dust, vibration and high temperatures. Therefore, it is very important to use production lighting equipment with high impact resistance, dustproof, waterproof and other characteristics.
LED lighting technology has been widely used in warehouse lighting. LED lamps have the advantages of high brightness, long life, low energy consumption and low maintenance costs, which can provide efficient and reliable lighting solutions for the manufacturing industry. In addition, the intelligent control system can achieve dimming and color temperature and other functions, according to different work needs to flexibly adjust, improve energy efficiency.
Through rational planning and application of manufacturing lighting solutions, production efficiency, quality control and employee safety can be improved. Proper lighting reduces eye strain, improves accuracy, and ensures that employees can operate safely during the course of their work. The design of manufacturing lighting should consider factors such as environmental characteristics, task requirements, energy efficiency and reliability to create a safe, efficient and comfortable manufacturing environment.Manufacturing Lighting, Factory Lighting, Production Lighting, LED Lighting Technology, Warehouse Lighting
