- pfdietz 5mo agoProbably neutron star collisions, actually.
- philipallstar 5mo agoIf it's not our sun then it isn't solar.

- Lambdanaut 5mo agoBy that logic, all of the Earth and the moon were once parts of stars, so tidal and geothermal are also solar. When people say "solar energy", they are usually referring to first order solar energy, directly from photons, not second or third order solar energy after it has been trapped into other sources of potential energy.
- eqvinox 5mo agoTidal kinda isn't solar since it's from rotation's and orbits' energies though.
