Nuclear fusion is the process of fusing atoms together. All atoms "want" to get to the atomic weight of iron, and so heavier and unstable elements will sometimes break apart [in a process called fission] and lighter elements in the right conditions will sometimes fuse together releasing energy. A nice example of natural fusion is the sun.
In this post though I want to write about harnessing fusion for energy. On paper the benefits of fusion to create electricity are tremendous: There is a huge amount of hydrogen in the sea that we could fuse, if we could get it working fusion could power us for a very very long time and the by product of it all is helium [which is useful, I'll try to post about that soon]. In real life fusion is more complicated: all attempts to create it have failed to get more energy out of the process than they put in [fusion requires a lot of energy to start a chain reaction].
In my opinion fusion could [and probably will be] humanity's main source of power in the distant future, but it is not a solution for our energy problem.
Beside helium , are there any leftovers? Harmful substances? Why is there an anti group?
