Storage of energy is one of the most urgent world problems and experts predict that the present rate of increase in energy use could exhaust the supply of coal and oil in the twenty-first or twenty-second century. One can expect that the world needs a source of inexhaustible energy. The one that we have shining down on us is the sun. Solar radiation is an ideal source of energy due to both its scope and cleanliness. And there is no charge for the energy that flows so freely from the sun. Unfortunately its collection and storage can be both difficult and expensive. The cost of transforming solar radiation into electricity is still very high. Nonetheless solar energy is now widely used in solar energy installations. I have never seen one, but I think one day I shall have a chance to do that.
