What is Fusion?

The video explains nuclear fusion, a process that powers the sun and holds potential for clean energy. It describes how fusion works by combining hydrogen isotopes to form helium, releasing energy. The advantages of fusion over fission include higher energy output and no long-lived radioactive waste. The video discusses two main fusion techniques: laser-based fusion at the National Ignition Facility and magnetic confinement in the ITER project. It also introduces the Wendelstein 7X stellarator, highlighting ongoing efforts to achieve sustainable fusion energy.
