FYI https://www.theguardian.com/environment/2023/aug/06/us-scientists-achieve-net-energy-gain-second-time-fusion-reaction
That's not really net energy gain from a practical standpoint. Technically yes, they get more energy than was present in their lasers, but those those lasers aren't created perfectly efficiently, and so the actual electricity needed to create them still is much higher than the energy output of the reaction
