Spherical Tokamak

A spherical tokamak is a type of device used to contain and control nuclear fusion reactions, similar to a donut-shaped reactor. Unlike traditional tokamaks, it has a more compact, ball-shaped design, which allows for a stronger magnetic field using less material. This design makes it potentially more efficient and economical for producing fusion energy—where light atomic nuclei merge to release enormous energy—aiming to generate clean, limitless power. The spherical shape offers advantages in stability and plasma confinement, making it a promising approach for future fusion reactors.
