Fusion, the nuclear reaction that powers the sun, occurs when the nuclei of two small atoms join together to form a larger atom, releasing energy and neutrons. Scientists had believed fusion possible only under great temperatures and pressures until the Utah researchers announced they had produced it at room temperature...
Fusion is a nuclear reaction which joins two smaller atoms together into a larger atom, releasing great quantities of 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...
...continues to this day. Says Celia Hunter, a lodge keeper who came to the territory 42 years ago: "Alaskans have always looked for the big bang that would solve all their problems." Some development schemes were downright absurd. In the late 1950s, Hunter helped quash a proposal to use atom bombs to blast an artificial harbor out of the northern coast. "The argument even then was jobs, jobs, jobs," she says...
Nuclear fusion, the process that fires the sun, usually 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...
