Not to mention supplying these hypothetical moon lasers with enough power to blast these mini-probes into another star system.

- Zikes 10y agohttps://en.wikipedia.org/wiki/Helium-3 https://en.wikipedia.org/wiki/Helium-3 ought to do the trick.
- Zikes 10y agoI'm a bit surprised at the downvotes. I'm no scientist, but I meant this suggestion in earnest. As far as my layman's knowledge goes, I've always understood the Moon's He-3 reserves to be a "vast, as-yet-untapped power resource".
- marcosdumay 10y agoPeople have to learn how to harvest power from fusion before.
- ars 10y agoYou know how they have chemically pumped lasers? So it would be awesome to directly pump the laser from H3 fusion. H3 fusion is actually very easy - I think we could do it today. We just don't have a readily available source of H3 for fuel.
- Ankaios 10y ago3He fusion is easy—you can do it in a garage with some hacked-together equipment. However, 3He fusion with net power output is exceptionally hard, even with complete disregard to cost. Much harder than deuterium-tritium fusion. We don't know how to do it yet.
- ars 10y agoThanks for the correction. Seems the rosy predictions I remembered are not accurate.
