Magneto-inertial fusion

Definition

Magneto-inertial fusion is a hybrid fusion approach that combines magnetic confinement and inertial confinement techniques to achieve nuclear fusion. This method utilizes magnetic fields to stabilize the plasma while simultaneously compressing it using inertial forces, creating conditions suitable for fusion reactions to occur. It aims to take advantage of the strengths of both confinement methods, potentially leading to more efficient and controlled fusion energy generation.
