...Utah fusion experiment, researchers B. Stanley Pons and Martin Fleischmann ran a current through a palladium electrode immersed in heavy water. They announced on March 23 that the deuterium nuclei in the water fused together into helium, releasing energy...
...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...
Under certain conditions, deuterium nuclei combine and form a helium nucleus and release a tremendous amount of energy as heat...
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...
...occurs when two atoms are squeezed together at very high temperatures to make one new atom. For example, two atoms of deuterium -- an isotope of hydrogen -- can be fused to form a helium atom and a neutron, releasing a sizable burst of energy. But before that can occur, deuterium nuclei generally need to be compressed with sufficient force to overcome their mutually repellent electrical charges. In H-bombs, that force is supplied by the detonation of an A-bomb. Conventional fusion techniques require giant magnets, powerful laser beams and particle accelerators. But none of these approaches have succeeded in generating...
