  Sunlight: 90,000,000,000MJ/kg

    Sunlight: 1.6e-6 MJ/m^3 (I do actually think solar will be the most useful energy source going forward)

    That is the total energy of a Kg matter according to E=mc2, if I'm not mistaken. How exactly are you planning to convert that matter into energy? Do you have a Kg of antimatter laying around your house?!

      Photons are their own antiparticle, so this is not an issue.
      • kimixa 3y ago
        Photons are the means for transfer for all energy sources at some level, so using that as a comparison for the actual generation method seems a little pointless.
