I mean, it's not happening in the near future - but couldn't commercial airlines be powered by SMNR or Fusion? The 787 has over 200,000 pounds of fuel. IIUC, SMNR currently can produce ~300MW weighing 1.4M pounds. Naively, it seems reasonable in 30 years or so we could produce one that weighs 140,000 pounds and produces ~30MW (not even a gain, just a smaller reactor) - which could power a current 787. Naively, I imagine they'd have more efficient plane designs in 30 years, too. And Fusion actually does seem less than 30 years away now. But who knows.
