A
In
summer,millions
of
people
will
head
for
the
beach. And
while
the
ocean
can
be
a
great
place
to
swim
and
play,it
may
also
be
useful
in
another
way. Some
scientists
think
that
waves
could
help
make
electricity.
“Have
you
ever
been
on
a
surfboard
or
boat
and
felt
yourself
being
lifted
up
by
a
wave?
Or
have
you
jumped
in
the
water
and
felt
the
energy
as
waves
crashed
over
you?”
asked
Jamie
Taylor
of
the
Wave
Energy
Group
at
the
University
of
Edinburgh
in
Scotland. “There
is
certainly
a
lot
of
energy
in
waves. ”
Scientists
are
working
on
using
that
energy
to
make
electricity.
Most
waves
are
created
when
winds
blow
across
the
ocean. “The
winds
start
out
by
making
little
ripples(波纹)
in
the
water,but
if
they
keep
on
blowing, those
ripples
get
bigger
and
bigger
and
turn
into
waves,”
Taylor
said.
“Waves
are
one
of
natures
ways
of
picking
up
energy
and
then
sending
it
off
on
a
journey. ”
When
waves
come
towards
the
shore,people
can
set
up
dams
or
other
barricades
to
block
the
water
and
send
it
through
a
large
wheel
called
a
turbine(涡轮机). The
turbine
can
then
power
an
electrical
generator(发电机).
The
United
States
and
a
few
other
countries
have
started
doing
research
on
wave
energy,and
it
is
already
being
used
in
Scotland.
The
resource
is
huge. We
will
never
run
out
of
wave
power, besides, wave
energy
does
not
