Joint European Torus

The Joint European Torus (JET) is a large scientific device located in the UK that aims to produce nuclear fusion power, similar to the energy process in the sun. It uses strong magnetic fields to contain and control hot plasma—an extremely hot, ionized state of matter—where hydrogen atoms fuse to form helium, releasing vast amounts of energy. JET helps researchers understand how to harness fusion energy safely and efficiently, which has the potential to provide a clean, virtually limitless source of electricity in the future.
