So they are ignoring the laser efficiency as well as the thermal to electric efficiency? If you did the same for a tokamak, stellerator or Bussard, would you get a similar ratio?
Jup. Fusion research is necessary and funding should be provided. But it is not close to commercial or generative viability.
So there is at the moment no working design for a generator as a plant that produces more electricity than it takes in.
Yup? Absolutely not, nothing close to this has been achieved with other reactors.
