The U.S. 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.
The scientists at Lawrence Livermore National Laboratory in California have achieved a net energy gain for the first time, in a fusion experiment using lasers, one of the people said. The FT first reported the experiment.
Fusion works when nuclei of two atoms are subjected to extreme heat of 100 million degrees Celsius (180 million Fahrenheit) or higher leading them to fuse into a new larger atom, giving off enormous amounts of energy.
