It looks like positive-return-on-energy fusion will almost certainly be achievable in 5-10 years, though it won't be commercializable for a lot longer than that.
I do like how incredibly simple and easy fusors are compared to the other types of fusion reactor, but sadly they are still very very hot where it counts.
