Nuclear fusion, a potential limitless energy source, has intrigued scientists for decades. Unlike fission, which splits large nuclei, fusion combines hydrogen nuclei to form helium, releasing more energy. Despite extensive research, achieving a sustained fusion reaction that produces more energy than it consumes remains a challenge. Facilities like the National Ignition Facility and ITER are exploring different methods to achieve fusion. However, issues like tritium scarcity and the energy break-even point persist. Companies like Zap Energy are working on innovative solutions, aiming to revolutionize the global energy system.

What is one major advantage of nuclear fusion over nuclear fission?

• Fusion produces more radioactive waste.

• Fusion does not produce carbon emissions.
