3. Solar Power refers to energy
from the sun that humans have
harnessed in order to power
things on earth.

4.  Solar power station can be constructed in two ways.
 They are:
1.Ground Based Solar Power Station(GBSPS)
2.Space Solar Power Station(SSPS)

5. Space-based solar power (SBSP) is the concept of
collecting solar power in space (using an "SPS", that is, a "solar-
power satellite" or a "satellite power system") for use on Earth.
It has been in research since the early 1970s.

6. • Originally known as satellite solar-power system (SSPS), was first
described in November 1968.
• In 1973 Peter Glaser was granted U.S. patent for his method of
transmitting power over long distances using microwaves from a
very large antenna (up to one square kilometer) on the satellite to a
much larger one, now known as a rectenna, on the ground.
• Between 1978 and 1981, the US Congress authorized the
Department of Energy (DOE) and NASA to jointly investigate the
concept.
• In 1997 NASA conducted its "Fresh Look" study to examine the
modern state of SBSP feasibility.
• On Nov 2, 2012, China proposed space collaboration with India in
SBSP.

12.  The full solar radiation would be available at all times except
when the sun is eclipsed by the earth. Thus about five times
energy could be collected, compared with the best terrestrial
sites.
 The power could be directed to any point on the earth’s surface.
 Uninterruptable power supply.
 The realization of the SPS concept holds great promises for
solving energy crisis.
 No moving parts.
 No fuel required.
 No waste product.

13.  The main drawback of solar power energy transfer
from orbit is the storage of electricity during off
peak hours.
 Interference with communication satellites.
 The entire structure is massive.
 High cost and require much time for construction.
 Risks involved with malfunction.

15. The solar energy available in space is literally billions of
times greater than we use today. Space solar power is by far the
largest potential energy source available. This technology on a
larger scale, combined with wireless power transmission can
supply nearly all the electrical needs of our planet. Space solar
power can completely solve our energy problems long term. The
sooner we start and the harder we work, the shorter "long term"
will be.
