Fuels of the Future

The increasing cost and decreasing supply of petroleum will eventually lead to widespread use of alternative aviation fuels and require the development of new concepts for using available forms of energy. This paper looks at future fuels and energy systems ranging from the more conventional kerosene type synthetics derived from oil shale and coal to speculative uses of solar and fusion power. Possible applications of these alternatives and advances in technology needed for their development are discussed. The aim of the discussion is to stimulate the imagination toward innovative development rather than to serve as a guideline for future events
