4.  Space-based solar power (SBSP) is the
concept of collecting solar
power in space for use on Earth.
 SBSP would differ from
current solar collection methods in that
the means used to collect energy would
reside on an orbiting satellite instead of
on Earth's surface.

5.  The SBSP concept, originally known
as satellite solar-power system
(SSPS), was first described in
November 1968.

6.  A satellite is an artificial object which
has been intentionally placed into
orbit such object are some times
called artificial satellite.

7.  A means of collecting solar power in space,
for example via solar concentrators, solar
cells .
 A means of transmitting power to earth, for
example via microwave or laser
 A means of receiving power on earth, for
example via a microwave antenna (rectenna)

8. 1. Solar satellite
2. Energy transmitted to the earth.
3. Energy received and distributed to
the earth

9.  Large arrays of photovoltaic cells
mounted on a satellite.
 Sun light will be capture and converted
into electricity by photovoltaic panel.
 Panel will remain in sun light 24 hours a
day. Producing a constant source of
base load power.

11.  There is no transmission losses so
each satellite is able to deliver a
quantity of power similar to the
nuclear power plant.
 This energy will safely transmitted by
the radio waves.

13.  This energy is received on the earth
by large easy to assemble grids
called rectenna. and it convert from
microwave to electricity then
distribute it.

14.  A rectenna is a rectifying antenna a
spatial types of antenna. That is used
to convert microwave energy into
electricity.
 They are used in wireless power
transmission that transmitted power
by radio waves.

15.  Eliminationof plant and wildlife interfer
ence.
 There is no air in space, so the collecting
surfaces could receive much more
intense sunlight.
 A satellite could be illuminated over 99%
of the time, and be in Earth's shadow on
only 75 minutes per night at the spring
and fall equinoxes.

16.  The large cost of launching a satellite
into space.
 The space environment is hostile ;
panels suffer about 8 times the
degradation they would on Earth.
