Stellarator

A stellarator is a type of fusion reactor designed to create and sustain nuclear fusion, the process that powers the sun. It uses twisted magnetic fields to confine hot plasma—a superheated gas of charged particles—without needing large electrical currents like other fusion devices, such as tokamaks. The complex shape of a stellarator allows it to maintain stable plasma for longer periods, which is crucial for efficient energy production. Researchers are exploring stellarators as a potential method for producing clean, virtually limitless energy, though challenges remain in achieving necessary temperatures and confinement times.
