US scientists achieve net energy gain in fusion reaction for second time


US Scientists at the Lawrence Livermore National Laboratory have accomplished a groundbreaking milestone in the quest for clean energy. For the second time since December, they achieved net energy gain in a fusion reaction, marking a significant step towards a clean and sustainable power source.

The successful experiment was conducted in the National Ignition Facility (NIF) on July 30, surpassing the previous energy yield achieved in December.

Although the final results are still under analysis, the breakthrough holds immense promise. Nuclear fusion, which involves merging two atomic nuclei into a heavier one, is the process that powers the sun. Scientists have sought to replicate this energy production on Earth to tackle climate change and secure an abundant and safe source of power. If the technology behind fusion reactions can be further advanced, it has the potential to produce power on an industrial scale.

The US Energy Department praised the achievement as a major scientific breakthrough with far-reaching implications. They believe it will pave the way for advancements in national defense and a cleaner energy future. The experiment focused a laser on a fuel target, fusing two light atoms into a denser one and releasing an enormous amount of energy.

By generating 3.15 megajoules of energy output while only delivering 2.05 megajoules from the laser, the scientists achieved fusion ignition, where the energy produced exceeded the energy used to drive the process. Despite this remarkable progress, nuclear scientists outside the lab caution that there is still much more research and development needed before fusion becomes commercially viable.

However, experts remain optimistic about fusion’s potential. Troy Carter, a physics professor at the University of California, Los Angeles, expressed excitement about fusion’s role in our energy future. As further advancements are made, fusion could emerge as a key player in providing a sustainable and abundant source of clean energy.
