WASHINGTON: The US Department of Energy will announce on Tuesday that scientists at a national lab have made a breakthrough on fusion energy, the process that powers the sun and stars that one day could provide a cheap source of electricity, two sources with knowledge of the matter said.
Fusion works when nuclei of two atoms are subjected to extreme heat of 100 million degrees Celsius or higher leading them to fuse into a new larger atom, giving off enormous amounts of energy. But the process consumes vast amounts of energy and the trick has been to get more energy out than goes in and to do so continuously instead of brief moments.
Running an electric power plant off fusion presents tough hurdles however such as how to contain that heat economically and to keep lasers firing consistently. Other methods of fusion use magnets instead of lasers.
