Its was first applied to use in 212 B.C., by the Greek genius
Archimedes. Solar energy was used to defend the habor of Syracuse against
the Roman fleet. Archimedes used a mirror or burning mirror as they
had called it, to set fire to the ships of the Roman fleets while standing on
shore (McDaniels 83). It wasnt until 1615 when Salomon de Caux
constructed the first solar device; a solar engine.

His device was made of
glass lenses, supporting frame, and an airtight metal vessel containing
water and air. This produced a small water fountain when the air heated
up during operation. This was considered to be more of a toy than a device,
but it was the first published account of the use of solar energy since the fall
of the Roman Empire (Cheremisinoff 1).
Some other use of solar energy after that was the solar roof and the
solar oven. The solar roof was thought up by Harold Hay. In a solar roof
system, water is contained in a clear plastic bag and it is placed on a black
metal roof.

Hay got the idea while traveling in India on a technical aid
mission for the U.S government. While there, he noticed that many people
were living in rusty, sheet metal shacks, which were hot in the day and cold
at night. Hays plan was to remove the insulation from the roof on winter
days so that the roof would get hot, and Replacing the insulation at night to
allow the shack to be warm through the night. Then in the summer, he
would so the reverse of what he did in winter to let the house cool at night
and replacing the insulation in the daytime to block out the heat. Then over
the years, Hay and a man named John Yellott constructed a 3- by
3.

7-m building using water basins as the actual roofing material. During
the summer, a slab of foam insulation was rolled back at night, and the
water would become cold through the night sky evaporation. Since the
water supply sat directly on a metal ceiling, it absorbed the heat from the
room and kept the building air-conditioned all day. During the winter, the
movable insulation was rolled back in the daytime which allowed for it to
collect heat. This generated enough heat into the house through the ceiling
at night to keep the room comfortable (McDaniels 179-181).
Then there was the solar cooker.

Developed by Augustin Mouchot in
France and by John Ericsson in the United States in the nineteenth century.
They wanted to develop a solar cooker that not only reached high
temperatures, but also was to be used as a means of heat storage enabling
food to be cooked after sundown. Mouchot built a solar steam engine that
operated a printing press in Paris in 1882. In the United States, John
Ericsson invented what he called the Ericsson-cycle which was a hot-air
engine for the making of solar heat. The suns rays would be concentrated
with the use of a parabolic reflector, which was designed to track the sun
across the sky in order to keep a constant power output.
There was also the solar oven.

In 1837, and astronomer from
England named John Fredrick Herschel introduced to the world a solar
oven. He built a small solar oven while .
