The desire of the modern man for more and more amenities and sophistication led to the unscrupulous exploitation of natural treasure. Though nature has provided abundant source of resources. It is not unlimited. Hence the exhaustion of the natural resources is eminent. The only exception to this is sunlight.
Scientist who had understood the naked truth had thought of exploiting the solar energy and started experimenting in this direction even from 1970. But the progress was very slow. Much headway is yet to be made in this direction. However as the impotents source of non-conventional energy and due to the limited source of conventional energy emphasis has given for the better utilization of solar energy.
But the application of solar cell, photovoltaic cell etc, we are able to concert only a small percentage of solar energy into electrical energy. But by using beamed power transmission from solar power satellite we can envisage a higher percentage of conversion. By beamed power transmission, we can extend the present system of two dimensional transmission network to three dimensional, if does not have any environmental problem as well.Recommend this topic
