I was looking at Sciam and their disparagement of fusion this month.
It seems that harder than fusion is breeding tritium.
The writer claimed it was a 50 to 75 year job to get it working - if it could work. And they haven't even started. And no plans to start.

What do you do when you run short of beryllium?
That doesn't sound like a high production source.
