Nuclear Fusion
Nuclear fusion is a process in which two light atomic nuclei combine to form a heavier nucleus, releasing a large amount of energy. This reaction powers stars, including the Sun, through the fusion of hydrogen into helium. Fusion requires extremely high temperatures and pressures to overcome electrostatic repulsion between nuclei. Unlike nuclear fission, fusion produces less radioactive waste and holds promise for clean, sustainable energy. However, controlled fusion for practical energy production remains technologically challenging. Research continues with experimental reactors like ITER.

Q: What world-changing idea, small or big, would you like to see implemented by humanity?
A: This is easy. I would like to see the development of fusion power to give an unlimited supply of clean energy, and a switch to electric cars. Nuclear fusion would become a practical power source and would provide us with an inexhaustible supply of energy, without pollution or global warming.
