So far they all use more energy than the produce and they only work for a fraction of a second. I do agree with many of the documentaries that the likely reason that fusion energy is always 20 years away is that the problem is never really funded in the way such a project should be.
I liked the ITER documentary: Let There Be Light. I'm sure it can be found without having to pay or something.
The ITER fusion reactor is currently under construction in France. It is expected that full operation will start in 2026.
