aren't pretty much all Li(Fe)Po cells made cheaply in China?

Yeah, I do agree it's a fair bit of Apple-bashing. I've also learned by reading through other replies in this thread that apparently Apple's standby mode is very reliable and consumes <1W. It's apparently also very easy to wake back up.

I can say none of that about my Windows and Linux machines 😅 so that may be where my confusion came from

wobei ich persönlich seit 15 Jahren immer nur Ortlieb 2.1 Taschen durch die Gegend fahr und den dritten Fixpunkt noch nie vermisst habe. Den entsprechenden Haken kann man ja ganz nutzen um die Tasche festzuklemmen.

Ich habe außerdem 2-4 Fahrräder gleichzeitig, da ist das 2.1 System einfach flexibler

And then how do you turn it back on?

ist das deren ernst? Bei aller Liebe für zivilen Ungehorsam und Einsatz für die Natur, aber diese Forderungshaltung in Verbindung mit den Stilblüten aus'm Blog ("die Cops haben uns gestern nach noch viel Erfolg gewünscht und dann gelacht") wirkt das irgendwie sehr unbeholfen

I'm with you in general - but the original timeline sounds much so much more quacky than what OP posted that in this instance I'm fine with it

I'd be real curious if you can back those statements up with peer-reviewed sources.

For one thing, it's not exactly like Uranium is mined in democratic nations with strong labor protections.

Also, "it's a neat toy" they say, meanwhile Germany produces up to 15% of it's total energy by solar: https://www.agora-energiewende.de/daten-tools/agorameter/chart/today/power_generation/01.10.2023/30.09.2024/monthly

I'm not saying none of this is true, but at the very least most of this is misleading. We're figuring out how to recycle old solar panels on an industrial scale: https://youtu.be/FCtEWveySsA

But progress is a bit slower than expected, mostly also because panels are a lot longer-lived than previously assumed (this is a good thing).

Yes, panels use rare minerals, but so does basically everything we consume and use nowadays. There's two answers to that.

A) does it still make sense climate-wise to use these resources in solar panels? This is what Life Cycle Analyses are for. In general, throughout their life cycle, PV modules help prevent more CO2 emissions than their manufacturing process releases, i.e. they are a net gain (https://www.mdpi.com/1996-1073/13/1/252). This is similar to EV vehicles, which break even around 60k km driven depending on your electricity generation (if memory serves https://www.europarl.europa.eu/RegData/etudes/STUD/2023/733112/IPOL_STU(2023)733112_EN.pdf)

b) is there a way to manufacture PV panels less resource-intensive and maybe even without relying on (Chinese) rare earth minerals as much? Yes there is. https://www.ise.fraunhofer.de/content/dam/ise/de/documents/publications/studies/ISE-Sustainable-PV-Manufacturing-in-Europe.pdf and see also sources above for next-gen differences.

That being said, for now it's still economically more attractive (usually) to implement Chinese panels because they're flooding the market. Still, it's a net gain as outlined.

thanks! I'm no mathematician and won't pretend to understand what's going on there, but I've stumbled across some "This knowledge is too much for a human brain to hold and therefore I have gone mad" tropes (https://tvtropes.org/pmwiki/pmwiki.php/Main/GoMadFromTheRevelation) that I was always wondering if there are actual IRL examples of this

[–] DrFuggles@feddit.org 1 points 1 month ago (2 children)

where could I read more about this paradox?

[–] DrFuggles@feddit.org 3 points 1 month ago

yo, do you blog? I would read your blog/diary/novel. You have a very calm(ing), distanced and at the same time immediate sense to your writing. It's good readin'!
