a terrible thought now occurs to me. maybe the algorithm does know.

I got the NukePod and while the power output and portability are great, the lack of radiation shielding is a real inconvenience.

I would love a tiny portable reactor for charging things. hasn’t someone made one from smoke detectors yet

On the plus side, you’ve probably stopped spending as much on shampoo.

I guess the question arises: do Google/FB have marketing research that shows that people engaging in, or attempting to emgage in ill-advised reconnections with exes* lead to more ad conversions…
*or perhaps more simply, people constantly bombarded with the thought of it…

there’s been a bunch of stories about how anxiety and depression can drive social media use, so… maybe?
( in google’s case, they’d have to derive relationship status from people’s online activity, and at least for me - google is also terrible at selecting ads, so i don’t feel like they’ve got much of a clue; in facebook’s case they know because people tell them: so possibly )

I’m not sure if you could make a fission reactor that small. According to Wikipedia the critical mass of americium (the stuff in smoke detectors) is between 57 and 75 kg, so that’s more “you could put it in a car” size. I don’t really know how critical mass relates to functional fission reactor designs, though.
Decay is said to produce about 115 W per kg, so you could make a radiothermal generator, but I expect that once you’ve factored in the other required parts it would still stretch the definition of portable, even if you’re only looking to get enough power out for a phone.
EDIT: yeah, see:
Prototype designs of Am RTGs expect 2–2.2 We/kg for 5–50 We RTGs design, putting Am RTGs at parity with Pu RTGs within that power range, as the vast majority of the mass of an RTG is not the isotopes, but the thermoelectrics, radiators, and isotope containment mass.
