solar power satellites
DESCRIPTION
SPS converts solar energy to normal electricity.TRANSCRIPT
Originally SPS known as Satellite Solar Power System ("SSPS")
SPS Converts solar energy into ordinary electricity
In SPS we use solar power plants in orbit above the earth
Solar power plants contains ground based receiving station
1968 SSPS(Satellite solar power system)
1973(Transmitting power over long distance)
1974(NASA singed a contact with ADL)
1999 SERT(Space Solar Power Exploratory Research and Technology program)
2012 Chaina proposed space collaboration with India
Space-based solar power essentially consists of three parts:
Means of collecting solar power in space
Means of transmitting power to earth
Means of receiving power on earth
Energy conversion (Solar Photons to DC Current)
Wireless Power Transmission to the Earth
Laser Power Beaming Experiments
Spacecraft Sizing
Will have no polluting consequences of fossil fuel systems. There is no air in space, so the collecting surfaces would receive
much more intense sunlight. Avoids the expensive storage facilities e.g., lakes behind dams, oil
storage tanks, coal dumps, etc. SPS will have no polluting consequences of fossil fuel systems Economically, an SPS deployment project would create many new
jobs and contract opportunities for industry
Solar energy is a promising alternative to using fossil fuels for the development of a sustainable carbon free fuel economy
Solar energy has a lorge potential to be a major fraction of a future carbon free energy It requires the involvement of both political and economical players ,but also improves the conversion efficiency and reduction of manufacturing cost
A recent experiment done by John Melkins at Hawaai islands showed that power can be transmitted over 100 kms by arranging 8 transmitters on a mountain peak.
But there observed a great difference between the transmitted and the received power.
But at the present state of knowledge we do not know that in future solar power from space could not compete with solar power collected on Earth.
We support research efforts aimed at increasing the efficiency of energy use. But we also support efforts to demonstrate new, environmentally benign energy sources.
