Fusion. Every ten years, plasma physics say that we would have fusion on the next ten years. :D

Maybe if we funded it appropriately. Actual funding has been really low:

It is quite depressing. The other day I've been reading an article about MRAP vehicle program - Wiki said the cost was estimated to be 50 BILLION

I had always heard it as thirty years. The ten year estimate seems to be a newer development! (My guess is that fusion is becoming less theoretical and shifting into an engineering problem; still hard, but a bit more deterministic.)

Well, once we have fusion we'll certainly discover taht it isn't completely safe.

That's because nothing on the scale we need is safe.
