DESCRIPTION
Two general concepts have been proposed for delivering solar power to Earth from space. In one, Peter Glaser of Arthur D. Little, Inc. (Cambridge, MA), proposed in 1968 that a huge satellite in geosynchronous orbit around Earth could dependably gather solar power in space. In the sec- ond concept, discussed here, solar power would be col- lected on the moon. In both ideas, many different beams of 12-cm wavelength microwaves would deliver power to receivers at sites located worldwide. Each receiver would supply commercial power to a given region. Such a receiv- er, called a rectenna, would consist of a large field of small rectifying antennas. A beam with a maximum intensity of less than 20% of noontime sunlight would deliver about 200 W to its local electric grid for every square meter of rectenna area. Unlike sunlight, microwaves pass through rain, clouds, dust, and smoke. In both scenarios, power can be supplied to the rectenna at night.

SOLAR POWER FROM SPACE
LUNAR SOLAR POWER - Introduction
Two concepts have been proposed for delivering solar power to Earth from space.
1) A huge satellite in geosynchronous orbit around Earth could dependably gather solar power in space.
2) In the second concept discussed here, solar power would be collected on the moon.
LUNAR SOLAR POWER SYSTEM
Technical Aspect
The LPS essentially consists of four parts:a huge solar collector, typically made up of solar cells (triple junction gallium arsenide )A microwave convertera microwave antenna on moon, aimed at Earth an EARTH based ‘receiver antenna’ to collect the power- called as rectenna
Explanation
AN appropriate natural satellite is available for the commercial development.Solar power is collected on the moon by solar collectors which is then converted to microwave beams by the bases on the lunar surface.Microwaves will deliver power to the rectennas.Unlike sunlight microwaves can penetrate through rain, clouds, dust, and smoke. Rectennas which contain large field of small rectifying antennas will then supply commercial power to a given region.Rectennas can receive power 24hrs a day with the help of relay satellites.

LSP ENVIRONMENTAL ADVANTAGES
ELECTRICITY FROM RECTENNAS– Does not produce greenhouse gasses, fuel spills, nuclides, dust,industrial wastes, etc.– Eliminates need for hazardous facilities (nuclear, dams, mines, etc.)– Enables biosphere-independent power– Enables remediation of environmental damage, recycling of goods, and non-polluting services and transport. ENABLES PLANETARY PROTECTION– Solar reflectors made from lunar materials adjust solar flux onto Earth.– Specialized LSP beams gently deflect dangerous asteroids & comets.
