The life sustaining power of the Sun has been obvious to human beings from the earliest times.All ancient civiliztions worship the Sun as the supreme God, and their kings and warriors claimed descent from him.He was known as Ra in Egypt, Surya, Savitra and Pushan in India.Mithra and asura in Iran, and assuriya,Hellios or Appolo in Greece, Jupitor Sol in Italy and amateresu in Japan.The last name country also name as Nippon,Which means tha land of rising Sun.In cenetral America, Incas of Peru, And Mayas and aztecs of Maxico worshipped the Sun as the highest God and built magnificient temples for him.Tha ancient rishis invoked the sun as the most excellent Bramanfor stimulating their intellect.
Sun's energy source....
the sun has been shining last of four and half billion years.The temperature at the core of the sun is whopping 14 million degrees.The tremendous pressure at the core due to the weight of the overlying two billion billion billion ten to power twenty seven tonnes of of material of the body of the Sun causes hydrogen, which forms 90 percent of the Sun's mass, to under go nuclear fusion to form helium and liberate energy according to the famous equation E=mc^2, where m is the mass that is converted into energy and c is the velocity of light(3,00,00 Km/Sec).Carbon and nitrogen atom catalyse the hydrogen fusion reaction. If we remember that in the Sun as much as 4 million tonnes of hydrogen is converted in to energy every secondthen we can have an idea of the scale of energy production inthe Sun.No wonder the Sun is so hot and bright.There is enough hydrogen still left in the Sun to keep it shining for another five-and-half billion years.
Non-renewable energy sources...
It is the solar radiation received by the Earth that has helped maintain the global temperature at the comfortable 30 degree celceus on an average .This has allowed water to remain in liquid state,which provide a congenial environment for the primordial life forms to appear,about three billion years ago.

hi this very well writing about solar energy
ReplyDeleteHi this is very valuable information for those person whose want use solar power systems
