Solar Energy A Primitive Resource: Solar Energy and Its Many Uses Ever since the dawn of time, the sun has been a resource we cannot live or do without, so its not such a shock that man has come up with the idea of solar energy. Solar energy had many uses. Some can be dangerous and some, a very valuable asset to the modern world. Solar energy is energy derived from the sun in a form of ultra-violet rays. 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 wasn’t 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 th
It is a good thing that our planet has so many ways of generating energy. While there, he noticed that many people were living in rusty, sheet metal shacks, which were hot in the day and cold at night. It can be dangerous because too much rays can cause you to sun burn, tan, damages your hair, and at the worst; skin cancer. Pham said that there is no use to solar power because when the sky is cloudy, there is no sun to power any of the solar product. The laser often consist of polished ruby rod that has a solid mirror at one end, and a high voltage flash tube wound around the rod. Hay"tms 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. Every other power source can be destroyed but the greatest power of all is the sun. 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. Works Cited Cheremisinoff, Pual N. In 1837, and astronomer from England named John Fredrick Herschel introduced to the world a solar oven.
