A stellarator is a type of nuclear fusion reactor designed to confine hot plasma using magnetic fields. Unlike other fusion devices, such as the tokamak, the stellarator employs a complex, twisted magnetic configuration to maintain stability and prevent plasma from touching the reactor walls. This design aims to achieve sustained nuclear fusion, which could provide a nearly limitless source of clean energy. The stellarator's unique shape allows for continuous operation without the need for pulsed magnetic fields, making it a promising candidate for future fusion power plants. Research facilities, like the Wendelstein 7-X in Germany, are exploring its potential to contribute to the development of practical fusion energy.
