Context- Scientists have been making efforts to build a fusion nuclear reactor for several decades.
- Nuclear fusion is a reaction in which two or more atomic nuclei are combined to form one or more different atomic nuclei and subatomic particles (neutrons or protons).
- The Sun is a main-sequence star, and thus generates its energy by nuclear fusion of hydrogen nuclei into helium. In its core, the Sun fuses 500 million metric tons of hydrogen each second.
- Energy released in most nuclear reactions is much larger than in chemical reactions, because the binding energy that holds a nucleus together is greater than the energy that holds electrons to a nucleus.
- Nuclear Fusion is considered by some scientists to be a potential energy of the future, particularly because it produces little waste and no greenhouse gases.
