Nuclear Fusion
Nuclear fusion is a nuclear process in which two light atomic nuclei combine to form a heavier nucleus, releasing a large amount of energy. It is the process that powers stars, including the Sun. Fusion requires extremely high temperatures and pressures to overcome the repulsive forces between nuclei. Achieving controlled nuclear fusion on Earth has the potential to provide a nearly limitless and clean energy source. Current research includes magnetic confinement (tokamak) and inertial confinement methods. No commercial fusion reactors exist yet, but many experimental projects are ongoing.

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.
— Stephen Hawking (Brief Answers to the Big Questions)
