Solar Wonders, ©2007 Florida Solar
On July 4, 1997, the Pathfinder spacecraft
bounced to a stop on Mars. The next day, the
rover Sojourner rolled out of one of the lander
petals onto the surface of the planet to begin its
mission of exploration.

Solar Wonders, ©2007 Florida Solar
Sojourner was able to move around the planet
and
examine rocks like this one named “Yogi” –
located
20 feet from the Pathfinder lander – thanks to
the power generated by the solar panel on its
back.

Dramatic as this was, it was just one use
of solar energy.
To many students, exciting projects like
this are what solar energy is all about.
But there really is much more to solar
energy technologies, how they are being
used, and how they impact our lives
today. This presentation will introduce
you to the entire field of solar energy.

Let’s begin our overview of
solar energy by asking:
What do you see here?
Take a close look –
is this the profile of a
beautiful young lady,
or the face of an ugly,
old woman?
They’re both here, but for
a variety of reasons that
make up your own
individual psychological
make-up, some of you see
one woman, some the
other.

Solar Wonders, ©2007 Florida Solar
When people think of solar
energy, the same thing often
happens. Some see it as
something for the future, others
see it as something that is here
today.

If you think solar energy is
something to be used in the future .
..
you may be picturing
something like this
solar array used by
the space shuttle to
provide for power
needs in outer
space. There are
people who think
that solar energy is
something not quite
down-to-earth and
not ready to use
today.

However, there are other people who think
of solar energy as something that’s been
around for a long time.
Solar collector for

For hundreds of years, people have wanted to harnes
the sun’s power for weapons, heating, and many oth
uses to make their lives more comfortable.

Solar Wonders, ©2007 Florida Solar
Actually, the first solar water
heating collector appears to have
been built in the 18th Century by a
Swiss scientist who constructed a
simple wooden box with a glass
top and a black base. It trapped
solar energy, and the collector
reached a temperature of 190
degrees Fahrenheit.
10
Solar Wonders, ©2007 Florida Solar
So which view of solar energy
-- for the future or for today –
is correct?
Probably a little of both.
Solar energy will certainly play an
important role in the future energy
needs of our planet, but it’s also here
today and ready for hundreds of uses
in homes, businesses, and industry.
11
Solar Wonders, ©2007 Florida Solar
The sun is an inexhaustible power
supply. It brings enough energy to
our planet every single day to meet
a full year’s worth of energy for
everyone on Earth.
And during the past century – back to 1891,
in fact, when the first solar collector was
manufactured in the United States, U.S.
industry has developed a variety of
products that have proven both reliable
and cost-effective in meeting all kinds of
energy needs.
12
Solar Wonders, ©2007 Florida Solar
The batteries in this solar-powered light in a
remote part of Key West, Florida, are charged
by the sun during the day to provide power for
street lighting at night.
13
Solar Wonders, ©2007 Florida Solar
But to many
people, solar
power today
means just
reliable
calculators,
watches and
other simple
home products
like this lantern
that use solar
power instead of
electricity to
charge the
batteries.
14
Solar Wonders, ©2007 Florida Solar
They don’t realize that millions
of people around the world
use solar energy because it is
the only available, reliable
power source for many of their
basic needs such as lighting
and water pumping.
15

Meanwhile, do-it-yourselfers
have long tried to build
their own solar systems to
take advantage of the free
power provided by the
sun . . .
16
Solar Wonders, ©2007 Florida Solar
The owner of a small laundry in northern
Florida tried to build his own concentrating
system for water heating. (We don’t know if
the sign in the background was put up before
or after this homemade system was built.)
17
Solar Wonders, ©2007 Florida Solar
But we do know that growing public
concern about environmental
problems . . .
18
Solar Wonders, ©2007 Florida Solar
including global warming, acid rain and toxic air
emissions, has in recent years turned a great
deal of attention to environmentally friendly
solar energy systems.
