Nuclear Fusion Power – An Overview of History, Present and Future

Fusion power offers the prospect of an almost inexhaustible source of energy for future generations, but it also presents so far insurmountable engineering challenges. The fundamental challenge is to achieve a rate of heat emitted by a fusion plasma that exceeds the rate of energy injected into the plasma. The main hope is centered on tokamak reactors and stellarators which confine deuterium-tritium plasma magnetically.
