Engineer turned a vape into a web server

The case highlights what can be done with so-called disposable kit. A 2023 UK study by the University of Oxford and the Faraday Foundation found that 1.3 million of the devices were thrown away each week, and reusing them in any format can't be a bad idea, not least since the batteries are perfectly capable of handling processing long after the addictive drug has been smoked.

MIT is developing concrete-based "supercapacitors" which could turn sidewalks and building walls into massive power storage facilities.

[classicdrogn]

I foresee a small problem with that, before even clicking the link - what happens when there's a earthquake, or some other damage accidental or intentional? "massive power storage" suddenly discharging tends to make for a much more exciting day than most anyone wants to have, and the ones who do are not likely to have the good of society im mind with it.

[robkelk]

That's addressed in the article: The power output actually drops momentarily when the concrete is stressed.

[Dartz]

Computer power has grown so much that it doesn't take much electrical power to make a basic device which *should* be dumb be able to do some pretty disturbing things.

90% of you laptop's compute cycles are probably being used to track you and sell you advertising these days anyway.

[classicdrogn]

I saw that, but while it is an interesting and potentially useful effect it still doesn't address what happens if some joyrider in a suburban assault vehicle Kool*Aid Man-s the garage wall that's got the power bank for recharging your EV in it.

[robkelk]

Ah. Now I see where you're coming from... and it's pure Hollywood.

Electrical batteries are not bombs. I can take apart, and have taken apart, properly-functioning charged batteries with no ill effects. You need capacitors for sudden discharges in real life, not batteries. And this is specifically described as a battery replacement, not a capacitor replacement.

[classicdrogn]

Hm, perhaps I misread it, but I thought it was more capacitor-adjacent. I still wouldn't be enthusiastic about the prospect, but chemically stored energy should be more stable than a straight up electrical charge, yes, given the materials they're working with.

As I said on Tumblr, "*Basidium-X intensifies*". (I wasn't sure enough of the chronology to say that 2025 PN7 arrived in Earth orbit around the time the book came out, but it turns out not to be that far off.)

[Bob Schroeck]

And here I thought I was the only one who remembered that book...

[Norgarth]

it seems vaguely familiar to me, it's been decades since I thought of that story and would not have been able to give you even a rough aproximation of the title.

[Bob Schroeck]

My elementary school library had the book and its sequel(s). At some point in the 90s, I think, I finally bought a copy of it somewhere for the nostalgia value. (I do that occasionally, try to find books I remember reading as a kid. I've rediscovered more than a few gems from the 1920s and 1930s that way...)

[Mamorien]

Either my elementary-school library or one of the shelves at the back of a classroom had the first sequel, Stowaway to the Mushroom Planet, but I've never actually read the original, and until I went wiki-walking, I had no idea there'd been four more books of Chuck and David's adventures after those two. (My childhood was mostly marked by reading books as my parents, teachers, and other Duly Constituted Authorities made them available. I skipped from The Marvelous Land of Oz to Tik-Tok of Oz because the children's section of Gulfport Public Library gave the latter pride of display one day; I read the rest of Baum's Famous Fourteen in nothing you could call order, unless you happened to be Discord or Sheogorath.)
