Introduction
Fusion21
Over ninety per cent of the world’s energy requirements is covered
today by fossil energy sources. The reliability of present supplies readily
obscures the fact that the climate problem, limited fuel resources, and
political instability call in the long run for a new energy system.
The situation is aggravated by the increasing energy requirements
in developing countries and the rapidly growing world population. Even
though the industrial countries succeed in achieving large-scale saving
of energy, requirements will rise world-wide.
The amount of economically efficient energy sources
capable of replacing coal, oil, and gas is, however, very limited: Besides
nuclear fission and solar energy there is the third possibility of fusion.
