Design, Fabrication and Performance Analysis of Solar Oven
I. INTRODUCTION
Today, every country draws its energy needs from a variety of sources. We broadly classified this source as conventional and non conventional.
1.1] CONVENTIONAL SOURCES
1) Fossil fuels,
2) Hydroelectric power,
3) Nuclear fission,
1.2] NON-CONVENTIONAL SOURCES
1) Solar energy,
2) Wind energy,
3) Bio mass and bio gas,
4) Ocean thermal energy,
5) Tidal energy,
6) Geothermal energy.
Energy is the prime mover of economic growth and is vital to the survival of a modern economy. Future economic growth crucially depends on the long-term availability of energy from sources that are affordable, accessible and environmentally friendly.
In many equatorial regions, native trees and bushes are being cut at an alarming rate to meet the growing demands for agricultural and, industry, and fuel wood and charcoal. The environmental consequences of this deforestation are severe, ranging from soil erosion and climate changes to flooding and the destruction of farmland. Moreover, dwindling supplies of wood mean that people must spend more time and energy in the search for cooking fuel. One alternative is to use kerosene or liquefied petroleum gas. But these are often imported and transporting them to remote areas is usually difficult. The next alternative is to use the sun, particularly in equatorial regions where solar energy is abundant.
Solar energy has the greatest potential of all the sources of renewable sources and if only a small amount of this form of energy could be used, it will be one of the most important supplies of energy especially when other sources in the country have depleted.
The solar power where sun hits atmosphere is 1017 watts, whereas the solar power on earth surface is 1016 watts. The total world wide power demand of all needs of civilization is 1013 watts. Therefore, the sun gives us 1000 times more power than we need. If we can use 5% of this energy, it will be 50 times what the world will require. the energy radiated by
