Throughout human history, the sun has always been a subject of speculation and worship. In fact, most ancient cultures have deified the sun, due to its giver life and energy giving qualities.
Thus the topic of solar energy is one of the oldest on Earth. Has undergone many changes and has been many schools of thought - starting with religion and ending in the field of Science.
In fact, few people know, much of Western civilization celebrates the return of sunshine a year, as the ancients did thousands of years.
Of course, I mean Christmas - going back to the winter solstice celebration, time when the Earth reaches its farthest from the sun, and begins to return.
Of course, the Christmas story is radically different from its original meaning. It had its own evolution. Originally a celebration of the return of the sun, becomes the celebration of the birth of Christ, and finally closed by an old kind that Christmas is Coca Cola. But this last point, the market is simply the modern workplace.
The first uses of solar energy
It is almost impossible to date precisely the first uses of solar energy.
But we know that Greek and Roman civilizations, among others, makes use of "energy passive solar "design in buildings.
Passive solar energy is the use of an architecture of buildings to capture the sun's heat and light.
In 200 BC BC, the Greek scholar Archimedes, used a concentrated solar power technology (now called "CSP") by combining the properties reflection of several polished bronze shields to concentrate sunlight and then set fire to a Roman invasion fleet was then besieging Syracuse.
(In 1973, the Greek navy recreated this scenario as an experiment, and succeeded in setting fire to a wooden ship located 50 meters.)
Socrates and the Romans
Even the famous Greek philosopher Socrates has commented on the benefits of home face south to take advantage of the sun's heat in winter.
The Romans used as a technique to cope with their homes in the south, but it took a little longer. Windows also installed on the south side, allowing the heat and sunlight to enter freely into buildings.
Throughout the first four centuries after Christ, the Roman baths heating systems using passive solar. The Romans built the bath house with large, south - the windows to the sun in this aspect of passive solar technology is still used by architects today.
With these methods, which have reduced the amount they need fuel to heat their buildings. And considering that he had to go out and cut their wood in those days was well worth it.
