Yes, the article mentions private company frustrations with ITER timescale delays and that it isn't likely to be up and running until 2035. Maybe he has ambitions of being the Elon Musk of nuclear fusion - It's either going to show up the big boys, or be a massive money pit.
Curious that it's planned to be 70% of the size of a commercial reactor though. I could understand a half scale prototype, but 70%? Why not go to 100% if you're building all that infrastructure.
