Eh I think it would be that simple, since that's what efficiency means. But sure, they haven't achieved engineering breakeven, but that's not what they claimed. But they're a lot closer than it seems when you don't take modern lasers into account. Even considering turbine losses, they're down to one order of magnitude. And this is worth noting: > The researchers also expect the energy gains to scale dramatically with energy input. We expect it to be strongly nonlinear, and it will only get better as we build designs that accommodate the increase in energy,” Spears said. “For some perspective, between the last event and this one, we put in 8% more energy in the laser and we got 230% more energy out in fusion.” https://www.hpcwire.com/2022/12/21/supercomputings-critical-role-in-the-fusion-ignition-breakthrough/ https://www.hpcwire.com/2022/12/21/supercomputings-critical-...
