...type of atom most common in fusion reactions is a form of hydrogen called deuterium. Although most hydrogen nuclei consist of just a positively charged proton, deuterium also contains an uncharged particle called a neutron...
Scientists theorize that conventional fusion yields one of two products: a helium nucleus consisting of two protons and one neutron and a high-energy neutron; or a radioactive form of hydrogen made up of two neutrons and a proton and a hydrogen...
...addition to being the energy source for the sun and other stars, fusion is also the process that powers hydrogen bombs...
Unlike fission, the other type of nuclear reaction in which large atomic nuclei split apart into smaller atoms, fusion does not produce significant quantities of radioactive materials...
Because of its potential for "clean" energy and the virtually infinite source of deuterium fuel in seawater, scientists have long tried to produce fusion power on Earth...
