pocket outdoor generator: tealight + mini steam engine

Here's one tiny model.

With power banks and solar chargers super affordable these days, this one seems gimmicky as shit. So I need to pack candles, and a little motor that's probably fairly fragile, and maybe a wind screen for the whole contraption (which also doesn't work when it's raining)

If you need more than a 20kmah power bank while /out/ for a week, you're doing it wrong.

The only reason I bring my phone/power bank us because I love quiet music when I make camp and sit by a fire. Especially if friends are with me.

That is a very dumb ass plan, like full retard man. They spin fast because they ain't doing shit for work. A steam engine would work, but you'd have to scale it up to the point where it wouldn't be nearly as fucking portable. Even then it would be pretty fucking inefficient since you are doing three stages of conversion, each with energy loss. If you want to power your faggy ass faggot shit inawoods with something portable there are a few ways. Portable solar, hydro, or even human electric generators. I don't know how well they work, but they sure as shit will work better than that crap.

>With power banks and solar chargers super affordable these days,
From what people wrote, I assume solar packs are close to useless, powah banks will not last long.
>fragile
I was thinking about something that would be properly designed, like for example those compact stoves that take little space while folded.

doubt it. probably won't make nearly enough power, being that a tea light burning gives off such low energy

K as in thousands? 20k-mah. Better?

I will ask at /tech for the numbers, I think issue is worth researching.
If not with tealight, th mbe something powered by wood like in portable stoves.
If not that, maybe those mini engines used in modeling to power miniature airplanes.
In general, I think there would be a market demand for miniature, portable, power generators.
I once saw one developed by one Europey country, the size of large bear can d able to work for 24h, to power soldiers nvg, thermals etc.

Pic related - another cool aplication of tealight in bushcraft.

at that magnitude, just use a thermocouple type device like a powerpot. efficiency is gonna be terrible anyways, but at least it's going to be small, simple and reliable.

how about 20 amp hours
