US scientists at the Lawrence Livermore National Laboratory have achieved net energy gain in a nuclear fusion reaction for the second time, The Guardian reports.
The experiment, conducted at the National Ignition Facility (NIF), produced a higher energy yield than the previous experiment done in December.
In December, the experiment generated 3.15 megajoules of energy (output) after lasers delivered 2.05 megajoules (input) to the target.
Nuclear fusion involves fusing light elements like hydrogen to create heavier elements and release substantial energy, similar to the process that powers the sun.
This technology holds promise as a clean and abundant energy source, as it emits no greenhouse gases or radioactive waste.
