"Nuclear Fusion Breakthrough: Exceeding Energy Input with Laser-Powered Reaction"
Scientists at the National Ignition Facility (NIF) in California have achieved a historic milestone in nuclear fusion energy by producing a laser-powered fusion reaction that exceeded "scientific breakeven," generating more energy than it consumed. The facility uses a technique called inertial confinement fusion, where high-powered lasers are fired at a carbon capsule containing deuterium and tritium, leading to fusion reactions. Advances in technology, including reducing asymmetries in fuel implosion and minimizing carbon contamination, have contributed to this achievement. While the fusion energy produced is currently below the electrical energy required to operate the system's lasers, further developments and improvements in efficiency could bring fusion energy closer to practical use as a sustainable and low-carbon energy source.
