It seems to me like a social score system is a direct upgrade to this in certain ways: participating in undesired behaviour will cause you headaches you cannot really solve with money. Too bad it "naturally" slips into mass surveillance, but restricting privileges would be a great alternative to reducing the ability to take care of necessities for you and yours.

Neat! I've occasionally looked into getting into DIY microfluidics, and one of the lowish-tech ideas I've seen is etching/engraving CD cases or other polystyrene sheets and baking them: this makes them shrink quite predictably, allowing for some really tiny channels. In arts & crafts they call them "Shrinky Dinks". PDMS is another interesting material, and could perhaps be somehow combined with 3D printing channels with alcohol-soluble polymers to print + dissolve the channels...

I'm sorry you feel that way. I'm not a native speaker but neither do I use any of those tools to write my comments here.

The community I have the privilege to be involved with in Kenya is facing many challenges when it comes to propagating access to solar energy, and one relatively small thing that can be done would be to service the lead-acid batteries most commonly used there: the environment is quite hostile to them as I understand it, and lead-acid is "the affordable chemistry" of choice. The problem is that there is a lack of knowledge and toxic waste (sulphuric acid, lead) handling capability. Otherwise topping up old batteries as a service is absolutely an achievable goal, much needed, and there is money to be made.

If you're talking about fairly modest sums ($10k to 100k) and Kenya in particular is on your radar, I think we should discuss this further. I'm not Kenyan myself (European), but I frequent the area and have a solid network and resources already in place to make things happen. How may I reach out?

Adding a data point here for posterity, in hopes that someone researches this topic deeper. I recognise myself from the above, apart from "intuitive feelings" as I don't quite get what shi.. the person meant by that. My mother noted that from a very young age I was fascinated by books and indeed did an unreasonable amount of reading growing up. My sibling thinks with words. Visualisation of real things is a challenge for me, but I think I'm reasonably adept at solving more abstract things (e.g. mechanical linkages) in a somewhat visual-adjacent way that I call my "imagination". This extends to memories, as if you were to task me to picture a dog, I would feel much more comfortable picking a non-existing, imagined dog than any the dogs that I've actually seen or met, such as family members' pets. I do some painting and could wireframe-sketch this imagined subject for you and "fill in the blanks", but trying to remember any actual moment spent with those beasts is laborious and results in something akin to one-frame flashes that are immediately gone and can't be recalled at will. Inadequate memory formation/recall have caused me grief, but I have no trouble remembering for example number sequences.

Always happy to share! I came across this while planning a 3D scanning (photogrammetry) rig. Perhaps you'll be the one to figure out gravity can be modelled as a rotation around an axis in a fourth dimension, wrapping clingy spacetime around itself? ;) I'm not clever enough for that.

I was immediately reminded of the anti-twist mechanism, perhaps unrelated but "reset rotation, twice/half" comes up there as well.

Ha, I had almost the exact same idea but just today. In my version though the subscription fee minus the dollar would be split evenly between all the subcommunities you follow, and within them by votes (by anyone).

This would incentivize creating communities that people would like to follow, not only for the content but also for the moderation.
