This actually happened a few go. Infact, we achieved fusion quite a long time ago, as early at the late 60s early 70s if I recall. This is just the published scientific findings, not the press release.
However, this was the first time that more energy was achieved from the fuel than was put in to make the fuel, which is a BIG achievement. However, the energy used by the lasers was MAGNITUDES more than the fuel produced. Big step, yes. The fusion savior we've been waiting for, sadly not.
I've followed a fair bit of work by the NIF. I wish their funding wasn't cut, but they are WAY behind schedule. Why should that matter though? Fusion is CRAZY shit. It is seriously the beginning to the most efficient energy we have ever known.
I have no doubt it'll happen in most of our lifetimes.
