Fusion is the power source of the sun and the stars, and has the potential to provide a green, non-global warming, and virtually unlimited source of energy. This talk provides an introduction to the physics that allows energy to be produced by nuclear fusion in a controlled and reliable way.
Also explained is why fusion devices must be large (and hence expensive), why and how materials must be developed to allow fusion to become economical, the importance of superconducting magnets, how Tritium fuel will be produced within a fusion power plant’s walls, and the prospects for the future.
Anthony Webster is a theoretical physicist working for UKAEA on fusion research at Culham near Abingdon. This research is funded by EPSRC and EURATOM.
