Does he ever once mention where he gets all these disposable vapes or what we can do about stopping them from entering the landfills?

When I first read your comment, it makes it sound like you've been watching the video for 20 minutes and it wasn't mentioned once. Turns out he starts talking about it around the 2:00 minute mark...

The amount of e-waste in general is truly nauseating. My employer just cleaned 30 years of “junk” out of our in house IT “tech shop” and the number of working but obsolete computers that went out (many simply because they couldn’t support Windows 11) is sickening to me. The amount of carbon generated from the mining activities, steel production, etc. that went into producing “obsolete” computers has to absolutely dwa…

The thought that disposable vapes are still not forbidden in my country (EU) is making me sick.

i see more and more of them thrown in small streets and parks these days (FR).. if I had secure storage i'd take them just like that youtuber, alas

They are illegal in Australia, but they are all over the ground. Littered like cigarette butts. Only now instead of just being plastic and some slightly toxic substances. It's a whole e-waste package.

On the other hand, free parts! Everything is reusable if you're determined enough.

The problem is how do recover these parts from a heap of trash

My reading of the WEEE directive is that no electrical equipment can be "disposable", it should all be recyclable and recycled.

Actual enforcement of this is non-existent. If you see a "disposable" vape discarded in the street, look for the crossed out bin logo.

"We could replace so many data centers with old desktops."

But I assume for way more energy costs? And the manual labour to sort out the different mainboards and make everything interoperable is not free either. But I guess it means lots of opportunity for unconventional low costs projects to scramble things together. Win 10 got another year of support, but I assume next year, even more computers will be avaiable quite cheap or for free.

Just curious: if you wanted to do something like that, but prevent a... thermal event, how would you protect an experimental battery realistically? Build a brick enclosure? A fire safe?

Ideally build it in away from your house, as others have said, but in terms of actual safety systems:

-get a high quality BMS from a reputable source, it should supports current limits and thermal probes - configure current limits with as much overhead as possible, the less you drive them, the cooler they'll stay - make sure you have sufficient thermal probes inside key points in the pack(s) and that they're configured in the BMS to cut draw - add thermal fuses as well, knowing where to put these is important, too - house the packs so to minimize fire risk and cascading issues, especially if space is not a concern

After all networked smartphones and computers were placed under control of the regime, resistance hackers relied on microcontrollers harvested from ordinary household devices like smart lamps and vape pens to slowly rebuild the covert but resilient mesh internetwork that became known as FreeNet.

Maybe this is not such a bad side of history to be on after all.
