It’s a pretty straightforward modification of the Caplan thruster. You scoop up bits of sun with very strong magnetic fields, but rather than fusing it and using it to move a star, you cool most of it (firing some back with very high velocity to balance things momentum wise) and keep the matter you extract (or fuse some if you need quick energy). There’s even a video on it! Skip to 4:20 for the relevant bit.
