Solar Power Satellite Historical Snapshot DuringBoeing designed a solar power satellite system that could supply most of the United States at the time with electricity. Satellites would be space platforms the size of a small city deployed some 22, miles 35, kilometers above the equator in geosynchronous Earth orbit GEO.
Discontinuation[ edit ] The project was not continued with the change in administrations after the US Federal elections. The Office of Technology Assessment concluded that "Too little is currently known about the technical, economic, and environmental aspects of SPS to make a sound decision whether to proceed with its development and deployment.
In addition, without further research an SPS demonstration or systems-engineering verification program would be a high-risk venture.
This is, of course, an absolute requirement of space solar power.
Pete Worden of NASA Solar power satellite that space-based solar is about five orders of magnitude more expensive than solar power from the Arizona desert, with a major cost being the transportation of materials to orbit. Worden referred to possible solutions as speculative, and which would not be available for decades at the earliest.
Perform design studies of selected flight demonstration concepts. Evaluate studies of the general feasibility, design, and requirements. Create conceptual designs of subsystems that make use of advanced SSP technologies to benefit future space or terrestrial applications.
Formulate a preliminary plan of action for the U. SERT went about developing a solar power satellite SPS concept for a future gigawatt space power system, to provide electrical power by converting the Sun's energy and beaming it to Earth's surface, and provided a conceptual development path that would utilize current technologies.
SERT proposed an inflatable photovoltaic gossamer structure with concentrator lenses or solar heat engines to convert sunlight into electricity.
The program looked both at systems in sun-synchronous orbit and geosynchronous orbit. Some of SERT's conclusions: The increasing global energy demand is likely to continue for many decades resulting in new power plants of all sizes being built. The environmental impact of those plants and their impact on world energy supplies and geopolitical relationships can be problematic.
Renewable energy is a compelling approach, both philosophically and in engineering terms. Many renewable energy sources are limited in their ability to affordably provide the base load power required for global industrial development and prosperity, because of inherent land and water requirements.
Based on their Concept Definition Study, space solar power concepts may be ready to reenter the discussion. Solar power satellites should no longer be envisioned as requiring unimaginably large initial investments in fixed infrastructure before the emplacement of productive power plants can begin.
Space solar power systems appear to possess many significant environmental advantages when compared to alternative approaches. The economic viability of space solar power systems depends on many factors and the successful development of various new technologies not least of which is the availability of much lower cost access to space than has been available ; however, the same can be said of many other advanced power technologies options.
Space solar power may well emerge as a serious candidate among the options for meeting the energy demands of the 21st century.
Dudenhoefer and Patrick J. This is the standard plan for this type of power. It is always solar noon in space and full sun.
Collecting surfaces could receive much more intense sunlight, owing to the lack of obstructions such as atmospheric gassescloudsdust and other weather events. A collecting satellite could possibly direct power on demand to different surface locations based on geographical baseload or peak load power needs.
Typical contracts would be for baseload, continuous power, since peaking power is ephemeral. With very large scale implementations, especially at lower altitudes, it potentially can reduce incoming solar radiation reaching earth's surface.
This would be desirable for counteracting the effects of global warming. The SBSP concept also has a number of problems: The large cost of launching a satellite into space The thinned-array curse preventing efficient transmission of power from space to the Earth's surface Inaccessibility: Maintenance of an earth-based solar panel is relatively simple, but construction and maintenance on a solar panel in space would typically be done telerobotically.
In addition to cost, astronauts working in GEO geosynchronous Earth orbit are exposed to unacceptably high radiation dangers and risk and cost about one thousand times more than the same task done telerobotically.
The space environment is hostile; panels suffer about 8 times the degradation they would on Earth except at orbits that are protected by the magnetosphere.
Space-based solar power essentially consists of three elements: It needs no protection from terrestrial wind or weather, but will have to cope with space hazards such as micrometeors and solar flares. Two basic methods of conversion have been studied:Of all the many spaceflight concepts NASA has studied, the most enormous was the Solar Power Satellite (SPS) fleet.
Czech-born physicist/engineer Peter Glaser outlined the concept in a brief.
Space-based Solar Power – The Power of the Future Space-based solar power is a method of using solar power satellites to collect solar energy so that it can be distributed for use all over the earth.
With this amazing technology, space-based solar power is the future of power generation. Its about Solar Power Satellite.. We wiil meet soon as world is running out of fossil fuels. Solar Power Satellite WPT via Solar Power Satellite 4 In idea for solar power satellites was proposed by Peter Glaser.
Between and , the Congress authorized the . SPS-ALPHA: The First Practical Solar Power Satellite via Arbitrarily Large PHased Array. During , Boeing designed a solar power satellite system that could supply most of the United States at the time with electricity.
Satellites would be space platforms the size of a small city deployed some 22, miles (35, kilometers) above the equator in geosynchronous Earth orbit (GEO).
