An experiment at Lawrence Livermore National Laboratory’s (LLNL’s) National Ignition Facility (NIF) appears to have approached fusion ignition as it recreated the extreme temperatures and pressures at the heart of the sun for a tiny fraction of a second. The momentous step has fueled new optimism for fusion energy.
The experiment on Aug. 8 “was enabled by focusing laser light from NIF—the size of three football fields—onto a target the size of a BB that produces a hot-spot the diameter of a human hair, generating more than 10 quadrillion watts of fusion power for 100 trillionths of a second,” LLNL reported on Aug. 18.
