  Tidal is also non fusion based

    Not with that attitude

  All atoms higher than hydrogen come from stars. So in the end, everything is derived from fusion. Therefore, geothermal and fission can only exist because of nuclear fusion.

  Fossil fuel is by extension of extension. Fission by extension of extension of extension.

  Fission is based on the fusion that took place in ancient supernovae.

    Neutron star collision. Supernova nucleosynthesis is also when fusion turns off.

  Everything is stardust so it’s everything fusion based?

    Heavier nucleosynthesis requires neutron star collisions, so not fusion-driven. Supernovas are also when fusion stops.

    The kinetic energy in that stardust, and the gravitational potential energy of stardust pulling itself into tighter balls, doesn’t necessarily come from fusion. There’s all sorts of cosmological forces and energy out there, and I don’t think they all trace back to nucleii smushing together.

      That’s true I suppose.
