Tiny H-bomb except pure fusion, and instead of a fission bomb as the trigger, you have huge lasers. You’d produce energy the same way, with heat being captured by some sort of spherical shield around the tiny bomb (which could also be breeding some of the fusion fuel out of lithium) and used to produce steam to run turbines.
This is the first time that the laser’s photon energy was exceeded by the energy produced by fusion. But this machine isn’t optimized as a power plant, just to demonstrate fusion (mostly to improve modeling of H-bombs, actually). The shots take hours to do, the tiny bombs are currently expensive to make, the chamber for the tiny bombs isn’t designed to capture heat, breed fuel, or even withstand damage from higher yield fusion. Another machine would be needed to demonstrate like 10-100 tiny bombs per second, and the efficiency (and repetition rate) of the lasers would need to be higher and the energy gain also needs to be much higher (but if they got “ignition” where the fusion heat helps sustain the reaction, this may be doable). And need to find a way to make these tiny bombs cheaper.
