Fusion power is the generation of
energy by
nuclear fusion. Fusion reactions are high energy reactions in which two lighter
atomic nuclei fuse to form a heavier nucleus. When they combine, some of the mass is converted into energy in accordance with the formula
. This major area of
plasma physics research is concerned with harnessing this reaction as a source of large scale
sustainable energy. There is no question of fusion's scientific feasibility, since
stellar nucleosynthesis is the process in which stars transmute matter into energy emitted as radiation.
