minus-squareFat Tony@lemmy.worldlinkfedilinkarrow-up8arrow-down4·9 months agoI thought because of the law of conservation of energy you couldn’t get more energy out of something you put in.
minus-squareel_eh_chase@lemmy.dbzer0.comlinkfedilinkarrow-up19arrow-down3·9 months agoI’m getting troll vibes, but I’ll bite lol. Fusion reactions are the exception since you’re turning some mass into energy according to: E = mc^2 There’s many quality videos on YouTube that can provide a better explanation than I ever could.
minus-squareMinusPi@yiffit.netlinkfedilinkarrow-up19·9 months agoThey’re not an exception to conservation of energy, it’s just that matter is energy in another form. Fusion reactors just harness that energy.
minus-squareel_eh_chase@lemmy.dbzer0.comlinkfedilinkarrow-up1·9 months agoTrue, thanks for the clarification!
minus-squarelogos@sh.itjust.workslinkfedilinkarrow-up15·9 months agoYou can think of the material being fused as fuel. More energy is produced by burning the fuel than in the spark it took to ignite it.
minus-squareRogueBanana@lemmy.ziplinkfedilinkEnglisharrow-up2·9 months agoThat doesn’t include the change in mass tho

No worries 👍
