Fusion Power What It Is
Fusion power is the production of energy by nuclear fusion. Fusion reactions are high energy reactions, where two lighter atomic nuclei fuse and transform to a heavier nucleus. This major area of plasma physics research deals with using 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 where stars transform matter into energy emitted as radiation.
In almost all commercial proposals, heat from neutron scattering in a controlled fusion reaction is used to work a steam turbine that drives electrical generators, as in existing fossil fuel and nuclear fission power stations. The current significant designs are the tokamak and inertial confinement fusion (laser) approaches. As of January 2016, these innovations are not yet practically possible, as they are not energetically viable because it currently takes more energy to initiate and contain a fusion reaction than the reaction then produces.
This educational video bellow explains the theory of fusion and the power it produces.
