eli5 How is it that things on earth can be “hotter than the surface of the sun”? If the sun is giving energy to basically everything on earth, wouldn’t any earth-item or organism only be able to mimic a fraction of the sun’s energy/power output?
Your space heater isn’t very hot, but it heats the room well. An arc welder is much hotter, but it’s much smaller so it’s not going to heat your room well.
