op-level design of the development of space solar power

GE Chang-Chun: space solar power cost significantly more than the existing way of generating electricity, no practical value. But especially through technological progress is the improvement of space transportation technology, can greatly reduce the cost of space solar panel power generation. Copeland company predicted that by 2030 the cost of space solar power generation can be reduced from the cost of 102 yuan / kW to 06,000 yuan / kW, quite This current conventional power generation.

David Dunlop: While the realization of the goal of clean energy from space, as well as its access to commercial status in the domestic and international markets, is still the matter after 20-30 years. But it is expected that the joint efforts of the United States, China, India, Europe, Japan, Canada and around the world support the development of space solar power countries, who is not space for energy development, a dominant force in the country to understand the potential of this technology can promote benefits.

Hsu Feng: In recent years, has been extensive debate and media coverage of alternative energy, sustainable development and global climate change has made a series of discussions, but has been a lack of knowledge and perspectives of support from scientists and engineers, at least in the mainstream media aspects of adequate scientific basis and informative has been scarce. Any large-scale collection and use the sun's energy (such as the use of space solar) as the most basic human ways of energy supply and ultimately will lead to a giant leap in the future of human civilization.

Wang Xi quarter, Min Guirong: the development of space solar cell 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.

The proposals should focus on development of heavy launch, should not step should step. Assembly and maintenance of the power plant should take the road of innovation, and to consider the play to the advantage of China's manned space station system of space-based services, to respond to the people-based robot, automatic and group formations of spacecraft are four ways to conduct in-depth analysis and comparison elect its excellent. 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.

The development of China's space solar proposed development in three steps: The first step argument grasp the system of total works carried out by the National Development and Reform Commission and the top-level design proposed initial development roadmap and engineering demonstration program; second step in-depth demonstration program, and to study its test validation work; entire third step in 2030 stand-orbit testing and validation work.
