10:01 < geneh2> helium3 mining makes absolutely no sense. we
10:01 < geneh2> make more helium3 on earth

11:08 < fleeky> if it will get people to the moon i say why not
11:08 < fleeky> also growing plants on the moon is stupid , bio reactors are more efficient , otoh ,, plants on the moon would be neato so oh well
11:09 < fleeky> geneh2: the bigger question i had "how long is it going to take for that harvester to lock up due to moon dust, 5 ,, 10 minutes?"
11:19 < L29Ah> are you feeding yourself off a bioreactor yet?
11:35 < fleeky> ??
11:35 < fleeky> as soon as i get to the moon , i swear
11:37 < fleeky> https://www.youtube.com/watch?v=BwQq63hRPDA
12:31 < L29Ah> i don't think you'd want relying on the moon on something you didn't test in every meaningful way on earth first
12:36 < fleeky> L29Ah it was a joke

22:56 < geneh2> never heard of quorn! Seems surprisingly mature, but you still need a starch source. Solein, food made from knallgas bacteria just needs hydrogen and CO2. It can supposedly be more efficient than photosynthesis
23:02 < fenn> i did some calculations on neutron spallation for He-3 production and get an EROEI around 20% (roughly number of neutrons per proton %)
23:03 < fenn> so it would be more like a nuclear "battery" for use in aneutronic reactors like spacecraft
23:03 < fenn> but of course we have regular neutron spewing fission reactors already too
23:04 < fenn> it's strange that i've never heard anyone raise this objection before
23:06 < fenn> also my calculations are crap and may bear no resemblance to reality
23:15 < fenn> objections to producing He-3 in reactors include: cost of Li-6 enrichment, handling large quantities of radioactive tritium for decades (half life 12.6yr)
23:16 < fenn> neutron economy (those neutrons could be used for breeding other fissiles etc)
