Among all the clean-energy approaches,fusion energy is generally considered to be the best option:fusion fuels such as deuterium (D) can be extracted from sea water while lithium for breeding tritium (T) is an abundant mineral and almost infinite in reserve;the fusion reaction is completely carbon-emission-free and generates no waste except for a small and manageable amount of radioactivity;fusion power plants are failsafe,free of potential nuclear disasters.However,fusion reaction occurs at extremely high temperature and pressure,so it is not easy to reach the ignition point and to have a container that confines the reaction.People have been pursuing fusion energy for more than six decades,but no fusion power plants have been built.
