Eli5 How do we get energy from both fusion and fission.

281 views

I heard recently a large hurdle to figuring out fusion energy was overcome and while there are still other challenges to face it’s possible that we could one day see fusion reactors.

How is energy released through both fusion and fission? Would it be theoretically possible to split heavier elements into lighter ones and then fuse them back into heavier ones to be split once more?

Protons repel each other but if you shove them together really hard they stick and release energy, more than it requires to shove them together apparently. If you have dozens of protons shoved together they become less sticky due to their repulsion. They release energy when they finally do fly apart as they naturally want to. They won’t fall apart all the way though. And it took more energy to produce those heavy atoms than we got out of them. But they were produced in super novas. But aren’t renewable.
