I would not count on it, since it's required for proper theme integration. A quick search confirms my suspicion: some font direcories are mapped.
I quite like the idea though, sort of a lite qubes or unmodified VM for all Firefox Flatpak users could be nice.
I'm sceptical of evaporative coolers. In the short term it might work well, but it increases humidity. That leads to sweating being less efficient and generally a worse situation than before.
There would need to be a way to remove moisture from the air, which ironically was the original purpose of air conditioners, not temperature.
So I don't want to tell you to panic but I can't find anything about "dslul" or their version of openboard.
It's the app id from F-droid, so I would assume it is legit: https://f-droid.org/packages/org.dslul.openboard.inputmethod.latin/

Last commit is two years ago. I'd recommend checking what you have installed. A quick search on GPlay finds what appears to be a clone that may or may not leak user data.
OpenBoard is no longer maintained. Heliboard is a good alternative.
I think Google Play on Graphene is a good compromise, since at least it does not have root access. Unfortunately it is very crippling to completely avoid Google on Android.
That being said, I heard others are using work profiles to isolate all apps using Google Play from their more private apps. I'm not doing that, but work profiles are nice for ... well work apps.
You still need to be able to defend against double spends, meaning I digitally copy my wallet and give two people the same 5β¬.
How are the hemp plants doing? /s
A fuel cell does not mean it's an ICE. It will still use an electric motor and probably even a small battery.
Hydrogen ICE exist, but are more complex and less efficient.
You could use Hydrogen to produce so-called e-fuels (we had a huge debate about them in Germany), but those can typically be used in normal ICE vehicels.
I would guess a swappable battery would be separated from the vehicle, similar to a gas bottle for a grill.
The battery would be rented for a small deposit and on swapping you only pay the energy + service fee.
I guess you could also buy one to own, but then could not swap that.
That's how it would make sense, at least.
I mean, other file sync apps upload everything to a third party while you're working with the device.
Then, when you use another device the first one can be turned off.
I'll add another condescending advice for you: Don't feed the troll.
No seriously, those two other commenters are either insane or trolling. They are completely ignoring your objective and just going on about "rejuvenation".
Please stay as you are and stand your well informed ground!
Even central currencies can work if you can make offline and peer to peer payments.
Not easy to pull off cryptographically, though.
