minus-squareFat Tony@lemmy.worldlinkfedilinkarrow-up6arrow-down4·10 months agoI thought because of the law of conservation of energy you couldn’t get more energy out of something you put in.

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-up12·10 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-up1·10 months agoTrue, thanks for the clarification!
minus-squarelogos@sh.itjust.workslinkfedilinkarrow-up9·10 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-up2·10 months agoThat doesn’t include the change in mass tho

No worries 👍
