Solar Energy#x2014;Its Nature and Possibilities as a Source of Power for Terrestrial Use

摘要

Important data relating to the solar energy emitted and received on the earth are given and its composition and nature broadly outlined. The availabilities of the various sources of energy are compared to bring out the relative abundance and the perpetual character of solar energy as a source of power. The possible multifarious uses of solar radiation for terrestrial application are enumerated. The principle of construction and the current status of development of the more important components necessary for harnessing Solar energy are briefly reviewed. A few typical systems already realized or in course of being investigated are described. Harnessing of wind energy is also briefly referred to. The need for extensive investment on work relating to the use of solar energy for meeting the specific needs of vast and sun-rich developing countries like our own is emphasized.
