    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.

          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.
