Remember the tokomak research that was being carried out from years back.
Well now its reached the stage where they are about to build a full size production device at Cullham in the UK.
It will be a spherical shaped core instead of a doughnut to give a much high efficiency.

So maybe the future for energy production is hot fusion, there is no doubt that it does work.
All we need now is a small version we can fit into the back of a DeLorean car and call it Mr FusionÃ, ;)
