Fusion reactors just harness that energy. permalink fedilink source parent hideshow 2 child comments replies: [–] el_eh_chase@lemmy.dbzer0.com 1 point 2 years ago (1 child) True, thanks for the clarification! permalink fedilink source parent hideshow 2 child comments replies: [–] INHALE_VEGETABLES@aussie.zone 1 point 2 years ago No worries 👍 permalink fedilink source parent [–] logos@sh.itjust.works 15 points 2 years ago You can think of the material being fused as fuel.
