3. SOLAR POWER TOWER
The solar power tower is 'central tower' power
plants or 'heliostat' power towers. It uses an
array of flat, movable mirrors (called heliostats)
to focus the sun's rays upon a collector tower
(the target).

4. Working principle of solar power
tower
Power towers operate by focusing a
field of thousands of mirrors onto a
receiver located at the top of a
centrally located tower. The receiver
collects the sun’s heat in a heat
transfer fluid, which is used to
generate steam for a conventional
steam turbine located at the foot of the
tower for production of electricity.
