More than a decade ago, the world’s most energetic laser started to unleash its blasts on tiny capsules of hydrogen isotopes, with managers promising it would soon demonstrate a route to limitless fusion energy. Now, the National Ignition Facility (NIF) has taken a major leap toward that goal. Last week, a single laser shot sparked a fusion explosion from a peppercorn-size fuel capsule that produced eight times more energy than the facility had ever achieved: 1.35 megajoules (MJ)—roughly the kinetic energy of a car traveling at 160 kilometers per hour. That was also 70% of the energy of the laser pulse that triggered it, making it tantalizingly close to “ignition”: a fusion shot producing an excess of energy.

Nuclear scientists in the US claim to have crossed a crucial milestone towards achieving a high energy output from nuclear fusion reactions that can kickstart a self-sustaining chain reaction. The successful experiment by scientists from the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory in the US could pave the way for clean nuclear fusion energy in the future that may help combat climate change.
