NIF was never intended to produce net power output. It's a research facility. The latest result is a major milestone demonstrating that net energy gain is achievable. LLNL, and other labs, are developing diode-pumped laser systems which are closer to 25% efficient, rather than 1%, and can operate at the high repetition rate required for power production.

That means the reaction would only need a gain of 4, rather than 100, to generate net power.
