Every professional that deals with stuff that needs around 1mm precision uses mm. Metal roofing, gutters, any machining, etc. It is to prevent ambiguity. I used to build roofs and for like wooden beams we used meters and cm, but that was because a couple mm here and there rarely ever mattered. All in all using mm is usually the best choice.
Yea. DNS is just an address book (name to IP). There's a bit more to how it is structured, but it's not that complicated.
Actually thinking about it, they would not have to remove the "domain" (tiktok.com or whatever it is), they (tiktok) would just have to stop using it for business. They could like put a banner that says "tiktok is no longer avalible here" or whatever.
Other part is IP. As you said, you could just change what dns server your phone asks for IPs and use it like normal. The government could block the IP at the big nodes going out of the country. Then you would have to use a vpn. Idk what they (usa or tiktok) have done, but I know tiktok will not actively try to skirt around it and will remove themselves. I would expect someone stupid like musky to try something, but big companies are usually serious.
Anyway, they can't stop vpns. But vpns are a pain for regular folk.
Electrolisis is relatively inefficient and wears down the electrodes. While not as bad on an industrial scale, those are still problems. And then you have to convert it back, that is even less efficient.
Good in theory, barely passable in practice. Growing sugar cane and making ethanol would be better, like brazil does it.
OP is... trying his best, I guess. For now lipo is the best solution. Actually multiple things are the solution. Pumped water has a delay that needs to be covered by something else. Flywheels have mechanical chalenges. Molten salt also has problems. Etc. They all compliment each other. IMO best single solution would be nuclear. Salt will be better then lithium, but in some years.
When batteries (ahcually accumulators, but whatever) are done properly, the fires should not go beyond one cell, if at all.
PS Gravity, except pumped water, is hilariously bad.
I once wrote a bc script that calculated parameters for the Blackman window for a FIR filter. (Had formulas already so not that impressive) Upped the precision until it needed like 30 sec to calculate, completely unnecessarely :).
