China wants to go to a whole new level of production of renewable energy. Chinese scientists plan to build in earth orbit the first ever space solar power. Its going to be placed at a height of 36 000 kilometers above the Earth, where no matter the time of day, meteorological conditions and atmospheric conditions of the planet, it can effectively and most importantly to collect solar energy for subsequent transmission to the ground station.
It generated electricity is converted into microwave or laser beam for transfer to the special collectors, located on the Ground. The station project was proposed by Chinese engineers still 2015. According to the Australian Sydney Morning Herald, citing a Chinese publication Science and Technology Daily, the experts of the Chinese Academy of space technology began to develop an early experimental prototype setup.
According to pan, by Jihan Dai of the National Academy of Space technology, space solar power could become “an inexhaustible source of clean energy for mankind”. Electric cars can be recharged at any time and in any place. The station will be able to provide the supply of electricity almost constantly and is 6 times more effective than any available on Earth is solar farm.
The project will take place in several stages. High-performance solar power station to start immediately will not. During the 2021-2025 years in the stratosphere is planned to launch several compact prototype for collecting solar energy and conducting tests on transfer to a ground collector. By 2030, scientists want to bring into orbit the power plant of megawatt class, and by 2050 – gigawatt.
According to the Vice-President of the Chinese Academy of space technology, China may become the first country in the world that creates a space solar power station that has a real practical value.
It is noted that the main technical difficulty in the establishment of such stations in orbit is not in the technology of collecting solar energy — the necessary framework is already there. The main problem is the weight of the station, which, according to current estimates, will be about 1,000 tons. Weight the same the International space station more than two times less and amounts to about 400 tons, said pan by Jihan Dai.
At the moment, experts are studying Chinese as one of the potential ways to solve this problem, the use of robots and 3D printing technology for the direct construction of the power plant in space. In addition, since the collected cosmic powerhouse of energy will be converted into microwaves for transmission to the terrestrial collectors, scientists also want to examine the potential effects of microwave radiation stations on the atmosphere and the ecology of the planet.
It is expected that the orbital space station will help to reduce air pollution emissions from numerous ground stations operating on fossil fuels. In addition, as one of the possible prospects of the use of plant as source of energy for the needs of the evolving programme of deep space exploration.
The news source adds that Japan, India and some European countries also are discussing ideas of using solar energy in space.
