Fusion makes a bomb like the sun.

Fission makes a bomb like chernobyl.

Seems similar, actually different. We're actually pretty good at fission, but fusion is way harder. The problem with fusion is that you need a huge amount of power to generate a slightly huger amount of power in return, and we are pretty crap at generating a big enough spike of energy to start the reaction and marginally worse at capturing said power after. All in all, pretty far away from practical fusion power.

Fission, by comparison, can happen when you have too many special minerals in a wrong shaped pile. We abuse this effect to boil water, and use that boiling water to make power.

I believe both. Fusion bomb was made after the fission one. So ya, that's a tough one.

But I suppose as long as we're just making wishes, there's got to be one like things can't explode but you can still get harmless energy from them or something like that, so stars still work. Idk,this one might require a physicist to phrase it right lol.

We don't have fusion yet. Once we do, it should solve a lot of energy demands.
