Since 1973, when the public became aware that shortages of gasoline for automobiles could drastically affect their personal lives, there has been much interest in solar energy. Many articles have appeared in the popular press about the potential of solar energy, and the federal government has allocated large sums of money for research in this area of energy. Most science textbooks now contain a chapter or two on solar energy utilization. Most engineering colleges offer courses specifically related to energy, and many of these place emphasis on the solar aspect. There is little doubt that the public, in all sectors, is well aware of the sun as a vast source of energy.
