Fusion Power - The Physics Holy Grail?

OK, so I've been looking up theories and options for new power sources with the global oil crisis and such. One which has really struck me is Fusion Power. Given that my country (UK) is now building a shit-ton more of the more dangerous Nuclear Fission power stations I'm wondering why people haven't invested more in this Fusion idea sooner.

So hit me with it, pros and cons, and whether you think it's attainable by the end of this century.

You know what would be more crippling, ``ad infinitum''? The heat death of the universe.
And considering that the sun will have turned into a red giant and consumed the Earth before the oceans would run out of hydrogen, getting to Jupiter would hardly be an issue.

There are plenty of fusion reactions that don't involve tritium, and even if there weren't and the only way we could get more was through neutron activation of lithium (which isn't the case), there's no shortage of lithium either.

Cold fusion hasn't been ``disproven'' (whatever that even fucking means in this context), we just haven't found a way to do it at this point.

And you're an idiot if you think a nuclear explosion would melt the whole of Antarctica. It'd create a puddle on top of an ice shelf, which would then freeze again.

If you're going to post, at least think before you do.

Do you have even the slightest clue how much energy it takes to get from the Earth to the moon and back, especially carrying heavy loads?
Shut the fuck up.
