Although my little fun fact doesn’t apply to THIS flywheel generator, I recently learned, that flywheel generators are used all over Europe to stabilise the Continental Europe Synchronous Area: They are constantly kept spinning and because of their inertia they level any voltage drops and peaks they encounter. Learning this blew my mind because I never would’ve thought that such a simple technology was used to stabilise our electricity grid.





I’m not thinking about safety precautions, but about “new(…ish…?)” health and nutrition guidelines for children.
For example: no honey before the age of 1, no raw meat during pregnancy, sturdier/bulkier car seats, and kids wearing bicycle helmets is more or less the norm where I live.
I can’t think of any more examples, but whenever my parents-in-law are visiting, there will inevitably be at least one thing where they scoff at us and say something like, “Ugh, kids these days… We did/didn’t do this or that, and it didn’t harm us, and we turned out just fine…”
