Space commercialization of solar energy in the future

Can spread in radio technology (WPT) basic aspects of the WPT the core microwave and electromagnetic fields and laser technology, in China in recent years in this area has achieved remarkable results, especially high-power laser emission during high-power microwave antenna. Laser transmission technology security issues can be resolved with the development of aerospace technology and weapons technology, the transmission of microwave communications, biotechnology and the human body is not a big impact and harm.

Yu Menglun: the development of the low-cost the heavy space transportation system is an important basis for the space solar panel power. Space solar power is an important way to solve the human energy, but geosynchronous orbit launch costs per kilogram as high as 10 million. According to analysis of the parties concerned, to make space solar power has a practical application, the need to geosynchronous orbit launch costs per kilogram dropped to 01,300 yuan. Which called for the launch vehicle launch costs per kilogram decreased by two orders of magnitude.

Ways to reduce launch costs: first, the formation of large quantities of the scale of the launch vehicle production system. Second, the development of reusable launch vehicle. Propulsion system analysis initially identified reusable launch vehicle development technology goals reused 100 times; Free repair (less or maintenance) of the rocket body, heat-resistant structure; the launch rpm weeks time for 1 day; emitted 25 tons operators. The progress of the development of the space transportation system is envisaged as the conceptual design of the system solution 2015; 2020 key technologies, small-scale demonstration flight test; the pilot carrier built in 2030; to build large spaceport 2040; 2050 initially built space solar power space transportation systems.

Yao Jianquan: the development of space solar power station is of great significance, the energy of the laser transmission space is one of the key technologies of space solar power station wood. For this critical technology roadmap sunlight effective condenser control, high energy utilization, the development of new laser materials, laser options. (Rod lasers, fiber lasers), laser efficiency, long-distance transmission The coherent coupling solar energy conversion and wireless energy transmission both new technology, the space environmental impact analysis, and to prevent, reduce the weight of the system as a whole.

Zuoxiu: space solar cell economy needs to be verified. Photovoltaic technology, from the first generation of crystalline silicon power generation technology, the second-generation thin-film power generation technology, turn to the third generation "low condenser + efficient silicon concentrator cells technology, the future may turn to the fourth generation of high-power condenser + GaAs concentrator cells technology. Contemporary photovoltaic industry concentrating power generation technology development must be to low.

Wang Xi quarter, Min Guirong: the development of space solar power station should pay attention to security issues, proposed first to consider microwave wireless energy transmission mode. The research and development of China's space solar pathway should not go, followed by the United States, road to the development of a number of power stations should not choose gigawatt across the 1930s, according to the principle of implementation middleweight 100,000 kilowatts to 500,000 kilowatts choose between.
