Space solar power station will become a reality next 20 years
Information Times reported, according to British media interest Daily Times reported 15 road, the human has already begun to use solar energy, but far from the ground to collect solar energy directly from space to collect solar energy as efficient. Scientists said that with current laboratory technology, human use of satellites to collect solar energy giant, and with wireless energy transfer device to transfer energy back to the idea of ??the Earth in the next 10 years to 20 years to become reality, and put this solar energy into economic benefits in the next 30 years is possible. This idea sounds like a 007 series film "Golden Eye" in the scene, but many scientists believe the earth space station will be to solve the problem of long-term energy solution.
Inexhaustible source of clean energy
Paris-based International Academy of Astronautics established the first global assessment of the technical feasibility of the space station s research team, a former head of NASA s space program ????? Head of the concept, has 25 years experience. Man Kensi that many pieces from the space station a few kilometers installed solar panels composed of satellites, these satellites in orbit above the equator run. Satellite will collect solar energy into electricity, then use the laser or huge microwave antenna directly to all corners of the earth grid.
Since space is not divided into day and night, the space station can achieve 24 hours of continuous power supply, its efficiency is to collect solar energy from the Earth five times. Once the technology becomes a reality, the space station will provide an inexhaustible supply of clean energy mankind.
Launch a satellite on the natural problem
Space power stations belonging to the emerging field of space science and technology, Man Kensi group s research indicates that humans currently heavily dependent on unsustainable fossil fuels, resulting in global environmental pollution. In addition, many scholars worried about oil and fossil fuel production peak in the next 10 years, and will ebb. Thus, sustainable zero emission energy production concept of the space station will gradually cause for concern.
However, the difficult construction of the space station. First, the construction costs are very high, only to rely on private capital is not enough space technology and government support is necessary. Many experts believe that the skeptical, unless the satellite into orbit in a sharp decline in the cost of, or the space station is difficult to become a reality. Man Kensi that create an efficient, low-cost, recycled commercial satellite launch requires at least several billion dollars. Second, the ultimate viability of the space station, but also must take into account the threat from space junk, and the results of detailed market research needs.
High cost: the cost quite a one-time payment nuclear power plant
Space power stations can produce the equivalent of ordinary nuclear power stations, nuclear power plant construction costs and is similar, but about 90% of the costs require advance payment. Space Energy estimates that the construction of a gigawatt space power stations need to invest $ 17 billion to meet its electricity needs of 100,000 households. However, the Swiss private company co-founder of Space Energy forced Saich said: "The main cost of the space station is the beginning, with the rocket launch satellites into orbit; and the cost of nuclear power plants spread over the entire period of use – about 30 years. On the whole costs, both roughly equivalent. "
US-India intends to develop
U.S. Department of Energy and NASA in space 40 years ago began to study plants. In September, the U.S. and India business, policy and national security experts urged both countries to conduct a feasibility study for development of space solar power, the target within 20 years solar energy into the space business interests. The research by the U.S. Foreign Affairs Committee and the Aspen Institute India, joint implementation, including the former head of U.S. National Intelligence Director Dennis Blair and former Indian ambassador to the United Na Ruisi Prachanda.
