The Future of Sustainable Energy: Fusion Reactors
Nuclear fusion, the process that powers the sun and stars, holds the promise of nearly limitless clean energy. It involves fusing light atomic nuclei, such as hydrogen isotopes, to form a heavier nucleus, releasing an immense amount of energy in the process. Unlike nuclear fission, fusion does not produce long-lived radioactive waste and its fuel is abundant (derived from water).
The primary challenge is creating and sustaining the extreme conditions necessary for fusion—temperatures exceeding 100 million degrees Celsius—while confining the resulting plasma. International collaborations like ITER are building massive tokamak reactors to demonstrate the feasibility of fusion power on a commercial scale. Recent breakthroughs in magnet technology and plasma physics have brought us closer than ever to achieving this "holy grail" of energy.
