Since mankind entered the electrification era, the various wires used to transmit power have become the most common items in people's daily life. Messy wire is also a difficult problem in life. From EHV transmission technology to the development of high temperature superconductor materials, mankind has made great strides in improving transmission efficiency and improving wire materials. However, in recent years, more and more researchers and related industrialists have begun to try their best to do so in the hope of being able to transmit power wirelessly and thus get rid of the dependence on electric wires. Recently, Japanese researchers have made tremendous breakthroughs in this area. In February this year, in Kobe, Japan, Mitsubishi Heavy Industries in its subsidiary Kobe Shipyard, the groundbreaking use of a 13 meters high and 8 meters flat-panel wireless transmission equipment has been previously replaced by the dominant status of parabolic wireless transmission equipment, After successfully converting 10 kilowatts of power into radio waves, it was sent to a wireless powered device 500 meters away and the blue LED bulb connected to the wireless powered device was lit. In March this year, Japan's Aerospace Exploration Agency (JAXA) also used other methods to successfully transmit 1.8 kilowatts of power to receiving devices at a distance of 55 meters by radio over radio waves. The success of this series of tests marks the ground wireless transmission technology has become more and more close to the practical stage. So, the practical application of wireless transmission technology for people's life and production will bring what convenience? As we all know, all the world's high-voltage power lines for the erection of the tower at the top, are equipped with a permanently flashing red light aviation obstruction lights, aircraft and other aircraft used to provide flight obstacle warning. However, many people do not realize that since these aviation obstacle lights themselves can not directly use the high-voltage power transmitted by high-voltage power lines, they must separately provide a separate low-voltage power line for their power supply on the power tower. In most cases, this low-voltage wire is roughly 500 to 1,000 meters in length and provides about 10 kilowatts of electricity. This is in line with the transmission distance and capability achieved by Kobe Port. Therefore, the current optimistic estimate is that in the next 5 years, wireless transmission technology can replace the above-mentioned low-voltage wire erection. In the past, when electricity towers and high-voltage lines were destroyed by natural disasters such as earthquakes, frosts and blizzards, repairs to power towers and re-installation of high-voltage power lines were time-consuming and energy-intensive. Therefore, how to restore the power supply in the power-off areas as soon as possible has often become a disaster relief process A big problem In the future, with the further improvement of the transmission capacity of wireless transmission technology, people can use helicopters to hoist the wireless transmission equipment and the powered equipment to the power-off area, so that the emergency power supply can be realized through the wireless transmission. In addition, offshore wind power, currently considered as the major new energy technology, is entirely possible in the future to directly transmit power generated by offshore wind farms away from coastline to the land by wireless transmission without the need to lay submarine cables, Thus drastically reducing the economic costs of construction and maintenance. For ordinary people, wireless transmission technology is also very broad application prospects. As the aging has intensified, more and more elderly people who are incapacitating themselves have begun to rely on electric vehicles, electric wheelchairs and other equipment to move, travel and take care of themselves. However, it is undoubtedly a difficult and troublesome task for a large number of the elderly who have difficulty in mobility by plugging and unplugging the power cord into a fixed socket to charge electric vehicles and other equipment. In the future, the maturity of wireless transmission technology will make it all very easy. As long as the elderly driving a vehicle equipped with wireless power receiving device into the wireless power transmission device near a certain spatial distance, the charging process will be completed automatically. In fact, in addition to the specific application examples above, the more important significance of wireless transmission technology lies in its possibility of opening up a whole new energy access channel for all mankind in the infinite space. For most people, solar power technology is not new. From home solar water heaters to huge solar arrays in the desert, are all ways people get energy by reaching the earth's surface of sunlight. However, any solar power facilities laid on the surface of the earth face at least two insurmountable problems: the day-night alternation of the Earth's rotation and the frost, fog, snow and rain caused by the general circulation. To this end, some researchers have proposed whether a special solar power satellite can be launched on a geostationary orbit above the equator of the earth closest to the sun and installed a huge solar panel that can generate electricity on both the front and the back. As a result, due to no longer trapped in the above problems, solar power generation satellite power generation efficiency will be 10 times higher than the ground solar power generation equipment. This is also the idea of ​​"cosmic solar power generation." It has been estimated that, in accordance with the current energy conversion efficiency of solar panels produced by human beings, if a square solar panel with a side length of 2.5 km can be fired on a static orbit above about 36,000 km from the Earth's equator Satellite, the power generation can reach 1 million kilowatts, enough to be comparable with a nuclear power generator. However, the attendant problem is that it is obviously impossible to adopt the traditional transmission mode of laying wires in order to transmit such huge electric energy from distant space to the earth's surface for human use. Therefore, the wireless transmission technology can make a major breakthrough, has become the "cosmic solar power generation," the grand idea can be transformed into reality lies. At present, with the continuous success of related experiments in wireless transmission technology, Japan's related research and development institutes with the METI as the core have predicted that by the 1940s, "solar solar power generation" will be put into practical use. At that time, the inexhaustible solar energy in the space will be converted into huge electric energy by the solar power satellite and transmitted continuously to the surface of the earth by using the wireless power transmission technology. This will undoubtedly play an immeasurable role in promoting mankind's gradual release of fossil fuels and the pollution it causes.
