I think the difference is luxury goods. If we compare beaters to beaters, my $5000 car (still works) I'd rent to people for at least $5/hr because it'd need maintenance based on runtime and miles. A $50 beater bike... hmm not sure what the rental price would bee, maybe $0.50/hr so it pays itself off after 100 days?
Nah, fusion power requires too many nuclear science packs and energy science pack IIIs to research in Outside. At $13,508 science per minute (SPM) it'll take several more years before it's ready.
I took concepts from Factorio and Oxygen not Included and applying them IRL. I bought some pipe and some heat exchanger, I made an ice melting cooler to improve habitability. Very much like ONI.
