|Oklo: Ancient African Nuclear Reactors

Oh, yes, my darlings, that’s right – ancient fission reactors in ancient uranium deposits in equatorial Africa. Two billion years ago, groundwater mixed with uranium ore, and we had fission! Natural freakin’ fission. How awesome is that? Back in those days, the uranium hadn’t decayed to the point where you needed humans to turn it into fissile material. Just add water, and you had yourself a nuclear chain reaction.
We have learned a valuable lesson here today: be careful where you pee in the wilds on a young planet.
