technology
uses
flat,
square
reflectors
“closely
packed”
on
a
rotating
surface
to
focus
sunlight
throughout
the
day
onto
a
receiving
tube
to
power
a
generator.
The
design
has
been
shown
to
have
a
conversion
efficiency
of
70-75%
at
400°C,
making
its
economics
comparable
to
that
of
conventional
parabolic
trough
collectors.
“Several
years
ago,
we
set
ourselves
the
objective
of
designing
a
solar-thermal
energy
system
that
is
cost-effective
and
entirely
made
within
the
region.
"We
focused
on
significantly
reducing
cost
in
comparison
to
available
technologies
through
increasing
efficiency
and
other
measures,”
