helium-3 is theoretically useful for nuclear fusion (instead of fission), a technology which still isn’t yet viable, and even if it becomes so, it might just be cheaper and easier to build a bunch of solar panels and batteries on earth than set up a mining operation on the moon. still, it makes for a neat science fiction concept, which is something i guess.

and yes, technically i just made a sequel to the comic “helium” called “helium-3”. hire me, microsoft.
