There is a tremendous amount of energy at work in the atmosphere at all times in the form of wind. Man has recognized this for ages and has used it to a limited extent by constructing devices, such as windmills.
Today, the rapidly diminishing supply of fossil fuels has prompted us to take a new look at wind as a source of energy. This publication will study some of the ways engineers have devised to harness wind.
