Here's a great Royal Institution Lecture by Kate Lancaster talking about Ultra Intense Lasers from 2017 :) [this video]

Fusion may be difficult but math and physics say we should be able to do it. Just because it's difficult and with a long time horizon doesn't mean you should throw it in the bin with "perpetual motion". (Cold Fusion however, you may throw in the bin) Just saw a talk [0] where they talk about using lasers to create fusion. The current puck used to kick start the process costs $1M, (paraphrased) "it needs to cost 20 cents before Fusion is viable. But hey, we're in the research phase!" [0] [this video]

What physics needs is a revolutionary (not evolutionary like the SSC or the LHC) particle accelerator. There are promising works with high-powered lasers, for example: [this video] But it seems the "spin particles really fast in a very long circular tube" is reaching the end of its life.
