Laser Fusion Experiment Unleashes an Energetic Burst of Optimism

Scientists have come tantalizingly close to reproducing the power of the sun — albeit only in a speck of hydrogen for a fraction of a second.

Researchers at Lawrence Livermore National Laboratory reported on Tuesday that by using 192 gigantic lasers to annihilate a pellet of hydrogen, they were able to ignite a burst of more than 10 quadrillion watts of fusion power — energy released when hydrogen atoms are fused into helium, the same process that occurs within stars.
