Laser-sparked fusion power passes key milestone

12 February 2014 by Jacob Aron
CLEAN energy inspired by the stars is the dream of scientists pursuing nuclear fusion, in which atomic nuclei fuse together and release energy. In a first for laser-driven fusion, scientists at a US lab say they have reached a key milestone called fuel gain: they are producing more energy than the fuel absorbed to start the reaction.

But the National Ignition Facility (NIF) in Livermore, California, is still a long way from sparking a self-sustaining fusion reaction with an overall gain in energy – a process called ignition. Currently, the reactor as a whole needs more energy to operate than the amount that is produced.
