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.
Not really, if absent means "no change", present means "update" and null means "delete" the three values are perfectly well defined.
For what it's worth, Amazon and Microsoft do it like this in their IoT offerings.
Rust has perfectly fine tools to deal with such issues, namely enums. Of course that cascades through every bit of related code and is a major pain.
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.
In the bottom picture it looks like the top "port" is just an air intake.
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.
Back in the day Signal was a Qt app, did that change?
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!
Solaar usually works well enough. Not sure if the gestures part is supported on MacOS.
I usually avoid depending on "hardware support" software for reasons like this. Once the software is no longer supported or as seen here, introduces some dumb "feature", it becomes annoying.
