Well, with that logic, coal is also indirect fusion

• gruturo 4y ago
  Yeah. And Wind, Gas, Hydro, etc. Basically everything except fission, tidal and a portion of geothermal. Admittedly it's not a terribly useful classification.

    Fission is just solar from different star.
    • pfdietz 4y ago
      The energy in fission ultimately came from gravitational collapse, not fusion.

  Solar is less indirect than they. It’s like if we made our own fusion reactor and rather than using it to boil water close by to generate steam, we put the water a few miles out.
