US to announce scientific breakthrough on fusion energy
The U.S. Department of Energy will announce that scientists at a national lab have made a breakthrough on fusion energy.
Technicians use a service system lift to access the target chamber interior for inspection and maintenance at the National Ignition Facility (NIF), a laser-based inertial confinement fusion research device, at Lawrence Livermore National Laboratory federal research facility in Livermore, California, United States in 2008.

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.
