The issue is, we've been able to get more energy out of a fusion reaction than put in for 60-70 years now. The H-Bomb is very good at doing that. You will say, yeah, but an H-Bomb is a one time use thing, and it has a habit of destroying everything. If you look into how the second stage of an hbomb is speculated to work, its pretty much identical to this experiment, that is by design, not by accident.
