Abstract In the present World scenario, one of the most pressing problems that the human civilization is facing is of the rapidly depleting sources of energy. The Industrial revolution in the early 19 th century has increased man’s dependence on machines and the industry. Hence in this brash rush of Industrialization the consumption of Fossil Fuels like coal and petroleum has increased to such a great deal that the known reserves have reached an all time low. Thus there is an inevitable need for developing alternative sources of energy in order to bridge this hiatus between the rapidly increasing fuel demand and the depleting resources available. In this paper, we have tried to analyse the potentials of Nuclear Fusion Reactors as a reliable alternative to overcome this energy crisis. Though the theories propounded are still in the state of infancy, they surely hold relevance for satisfing the fuel demand in the future in both on earth as well in space stations. Furthermore, the world environment dectates that any future fuel should be clean and non polluting. We know that Fusion, a source of the sun’s energy offer a clean, potentially limitless source of electricity and power. Hence a magnetic fusion reactor by using plasma would manage to bring about the nuclear fusion reation in a controlled way. Plasma is a new state of matter in which most of the atoms are ionized due to some sort of `violence' and breaking away of the originally bound electrons.Within the plasma, colliding deuterium and tritium nuclei would fuse into helium nuclei and release energy to be converted into electricity.
