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.

I'm actually a biologist by training but I started getting into sonoluminescence through pistol shrimp, and from there I learned more about bubble fusion.

What do you think about bubble fusion as a feasible way to create internal confinement fusion? Do you think people would be willing to invest research in it even after Taleyarkhan fucked everything up? I would really like to see more research into it...to the point where I may actually decide to change fields...but I doubt there's much funding for it.
