I installed solar panels in my backyard, and then texted my dad that my basement is now powered by fusion with a roughly eight minute delay.
He then asked "isn't pretty much all power on earth outside of nuclear fission technically done by fusion if we give enough of a delay?". I didn't really have a rebuttal to that.
Not geothermal I would think?
Actually thinking back I think he might have said "nuclear fission and geothermal". This was months ago.
Arguably nuclear fission in this case.
Geothermal is not nuclear fission. It's some combination of primordial heat from the formation of the Earth (which was gravitational energy) and radioactive decay (which is distinct from fission).
