This publication has been prepared to help planners and engineers consider the potential and application of alternative sources of energy for prime movers. Research and field application are continuous in many parts of the world, but the degree of success varies. As new information becomes available, systems developed over recent decades, and even long before that, may be modified or refined to take advantage of new ideas and modern technology. It is an old subject, but innovations continue.
