Nuclear fusion – unlimited green power

Abstract

The power of stars, driven by nuclear fusion, holds immense potential for addressing our energy needs. Fusion involves small atoms combining into larger ones, releasing substantial energy. This process, occurring in stars like our Sun, powers Earth's weather, and water cycle, and sustains flora and fauna. Fusion's energy source lies in the mass of particles, particularly the binding energy of atoms. Comparing different elements, the fusion of small elements surpasses the energy potential of fission in heavy atoms. Practical fusion processes, like combining deuterium and tritium, yield helium and spare neutrons, releasing substantial energy. Despite technological challenges, researchers aim to replicate star-like conditions on Earth, requiring temperatures exceeding 100 million degrees Celsius. Promising technologies include torus-shaped tokamak reactors. Achieving sustained fusion for net power production remains a crucial milestone. Fusion's advantages include abundant fuel sources like deuterium from seawater, minimal greenhouse gas emissions, and no significant radioactive waste, making it a promising green energy solution. While challenges persist, fusion's potential as a clean and abundant energy source fuels ongoing research, offering a transformative solution for the future.
