What's the distinction between product and by-product then?

I called it a 'by-product' because it's not the product we're actually aiming for, not the point of the exercise - if oxygen were produced instead (by whatever science-ignoring magic) we wouldn't mind.

But in Fusion what we are doing is intentionally creating helium. It's the mechanism we want.

In fission it's a byproduct in that it's not our main intention.
