Power generation through the release of heat through a controlled nuclear fusion reaction. The hot plasma is confined in a magnetic bottle. Dedicated expert systems and subturing computers are required to ensure that the magnetic bottle remains at exactly the right charge to safely hold the plasma. Fusion generation is a widely relied upon power source throughout much of the galaxy, both to power large vehicles and settlements. Although not as efficient as amat, it is considerably safer, since there is no need to store amat and a magnetic failure means the hot plasma disperses causing only minor local damage.
