            The amusing thing is that the sun is actually quite a shit fusion reactor. It's power per unit volume is tiny. It just makes it up in sheer volume. A solar level fusion reactor would be almost completely useless to us. Instead we need to go far beyond the sun's output to just be viable.

            It's like describing one of the mega mining dumper trucks as an "artificial mule".

              I think this energy density math really depends on whether only the core or the whole surface area is taken into consideration.

                  Even the core only has an output of 200-300W/m^3.

                    They say "artificial sun" because that's what it is though, there's no fusion reactions here they're just microwaving hydrogen to millions of degrees to study the kind of thing that would happen IF somebody runs a fusion reactor for 22 minutes.

                      Someone once told me a sun is just a fusion nuclear pile reactor and... Like... I guess.

                        That's about the energy output per volume of a 70 year old cyclist.

                          Arguably, the nearby sun scale fusion reactor has been fairly useful for us. Nowadays we can convert its output directly into electricity using solar cells

                            I never said it wasn't useful, just a very low efficiency reactor. Then again, if it was better, it would burn out faster, which would be bad for life on earth.

                                  What I'm hearing is that we should mine the sun and make better use of all that fuel.

                                    It produces about the same power per cubic metre as compost does, which is pretty crazy when you think about it.

                                      That's part of the reason a moon base could be viable. The sun outputs a reasonable amount of helium 3, which is great for fusion reactions. Unfortunately it tends to sit at the top of our atmosphere and get blown away again. On the moon, it gets captured by the dust in collectable quantities.

                                          Sure, but it makes up for that by having an idiot proof design.
