NetEase reported November 17 to explore the British media, according to news: an international team of scientists that capture solar power from space, then the energy through the wireless transmission back to Earth is a cost-effective way of generating electricity to meet the world’s electricity needs. They are the laboratory by means of a series of technical research and development, the use of satellites in orbit to capture solar power, and then back to Earth. The idea that in 10 or 20 years have the technical feasibility, or less in 30 years time (or 20 years) with economic feasibility.
International Academy of Astronautics: Space solar power a significant
the Paris-based International Academy of Astronautics Research Group, said: in the 21st century to meet the global demand for energy to play an important role. solar power collected in space and then transported by way of wireless energy transfer to the international assessment of the feasibility of the Earth.
researchers said the government should invest in the idea to use solar energy in space a reality. Because of uncertainty in the economy, private sector funding alone is difficult to do this. Study indicated that the government and the private sector should increase investment, support for researchers to explore the economic feasibility of this idea. Due to continued reliance on a limited and polluting fossil fuels, mankind’s energy future challenges. In this case, the development of solar energy technology has been imperative.
yet researchers assessed the cost of building the space station
researchers did not assess the cost to build solar power stations in space. Some scientists said the use of space solar power to meet global energy demand is a potential long-term solution. According to scientists, the idea of a first specific implementation of solar power satellite into orbit above the equator, and then continue to launch these satellites, space stations constitute the group. The width of each solar station will reach several kilometers, can capture the sun 24 hours a day.
ground solar panels to convert sunlight into electricity, the capture efficiency of solar power stations up to only half the space. Satellite capture of solar energy will be converted into electrical energy, and then transmitted through a large microwave antenna or laser delivery to any region on earth grid. Skeptics point out that this idea is doomed bankruptcy, at least substantially reduce the cost of commercial power station into orbit before the case. In addition to higher costs, create barriers to the space station including space debris and the lack of relevant market research.
this study conducted from 2008 to 2010, to accept peer-reviewed research papers. Research indicates that use of space solar business prospects continue to improve, in part because the government encourages the development of clean green energy technologies. Mankins said the verification scale trial of this technology will be comparable to 400 tonnes of the International Space Station, the use of R & D for other low-cost space exploration rocket into orbit.
According to the research team estimated that the development has launched full-scale commercial solar power satellite capacity, and low-cost reusable launch vehicles requires tens of billions of dollars. In order to implement this huge project, the government space agency, business, universities and NGOs need to work together to make the necessary research and development. Over the past 10 years, because of concerns about future global oil production and other fossil fuels production will peak and decline in the international community to build more and more interest in improving the space station.
optimistic assumptions: 20 years, commercially viable
order to meet the energy demand and stimulate economic development and reduce fossil fuel greenhouse gas emissions, many countries in the development of new energy technologies. Study how solar energy has been 40 years of space history, including the U.S. Department of Energy and NASA, including a range of agencies have carried out such research. In September, the U.S. and India business, policy and national security analyst research team called the US-India cooperation in the development of space solar power station for the feasibility study. Goal of this project are: commercially viable within 20 years.
Zhezhi research team from the U.S. Council on Foreign Relations and co-sponsored by A Sipeng India Institute members include former U.S. Director of National Intelligence Dennis Blair and former Indian ambassador to the United Na Leishi Charles de. Imagine coming home the Air Force chief, Alabama Maxwell Air Force Base, Center for Strategic and technical Colonel Michael Smith said: the need for cooperation, expand research in this area.
