LPP has faced a lot of delays though, because their budget is so small. They originally expected to have shown proof of feasibility by now, but keep running into problems as they scale up. They spent a year trying to get the high power switches to reliably switch simultaneously. Then there were problems with the electrode alignment. Now they're trying to deal with some vacuum contamination problems.

I suppose it's similar to ITER, but with an order of magnitude different budget.
