I'm so sorry, but you don't split (fission) helium to get energy. You combine (fusion) helium to get energy. You split something heavy like uranium to get energy.

Oh, come on, now you're just splitting hairs!

From a hairy uranium

I hate that stupid physics ruins this very good joke :/

Xenon and Krypton are noble gasses that are produced from fission, but I don't think they're ever the pre-guillotine input.

What if I fuse uranium huh? What then pal?!!!?

[–] rImITywR@lemmy.world 12 points 1 year ago (1 children)

The point is the "energy well". That is the elements "in the middle" of the periodic table are more stable/at lower energy states. So fusioning heavy elements or fissioning light elements move to higher energy states, so it will take more energy in than it releases.

And 'the middle' is iron, in case anyone is wondering.

Congrats on your newly discovered element 184!

For like a nanosecond

Splitting helium requires energy. Go for Radon or something.

The purpose of a guillotine is to deliver energy

[–] OofShoot@beehaw.org 3 points 1 year ago

Perhaps I want clear. If you split helium, you lose energy. You have to go above iron if want to release energy from fission (mostly).

[–] anton@lemmy.blahaj.zone 2 points 1 year ago (1 children)

But a guillotine doesn't deliver more energy that a nuclear explosion. Given the endothermic nature of splitting helium it would have do the splitting and the exploding.

You ever think there's a reason nobody puts cool in the same sentence as physics :p
