“This has produced more energy than any previous inertial confinement fusion experiment, and proves ignition is possible, paving the way for reactions that produce more energy than they need to get started.”
Ignition is real progress. It is not more energy out than the lasers put in, and the next milestone the scientists name is exactly that. NIF spent over a decade chasing this one result. Fusion power is still thirty years away. It is just a more confident thirty years.
