This was really helpful, thanks! I've been thinking of making a phone charger powered by a Stirling engine to have as a conversation piece, and I'd seen these models of desktop Stirling engine online; I had my doubts as to whether they could effectively charge a phone, especially since they never list their brake power, so it's very useful information that I'll need one of the two-cylindered models at least.
Of these small kits, definitely more cylinders. I’ve seen larger ones like made from coffee cans and I think a larger one with a heavier flywheel would be the way to go but on something like that you’d be using a lot more fuel as well… 👍
The eddy currents and resultant diamagnetc nature of the copper when moving in a magnetic field is what slows these motors when moving under a load. I really want one of these sterling engines though, one with more 'pistons' maybe. Thanks for the video, I have liked and subbed. Peace from Ireland to you and yours mo chara.
Thank you for watching! So at .5 amp, about the same as a standard USB A, (I think) a phone will charge all the way in 2.5 to 3 hours (not fast charging or USB C) so on the Stirling engine I got it would probably be about that maybe a tad longer for the fluctuating current BUT realistically the fuel in the jars only lasts like 5-10 minutes. So you'd be refilling those a lot... you could use a sterno can, that burns longer but not as hot as alcohol... Iv'e read a few camping debates about sterno vs alcohol stove but that's for cooking and not for maximum output... so short answer I'm thinking 3 to 3.5 hours if you kept it going.
Well, a transformer that increases amps would decrease voltage. Likewise to increase voltage would reduce amperage… I think. And as I was at the minimum voltage for the phone to recognize, I didn’t think a transformer would help. I could be wrong…
Thank you for calling Shenanigans, I pretty certain I know exactly what video you are referring too.
Dang you really should use your voltmeter in amps mode to clear up your uncertainty

Great video thanks
You’re welcome! Thanks for watching!
Very cool!
Thank you!!
Turn the motors vertically and use a rocket stove for the heat source.
Oooo! I like the way you think!
I think that at sunny days these stirling engines would be in very good use in combination of solar energy (fresnel lens)
That would be a great experiment! Now I gotta see if anyone’s done it 😁
Thanks for the honest review, so many fake videos
I wonder how many it would take to charge your phone. Maybe 2 4 cylinders? Or 4 giving a total of 16 cylinders

Very enjoyable vid !!!
Subbed.
Thank you!! 👍👍
I was just thinking...what better way to treat some finish grade wood than applying a vinyl wrap. 🤣🤣🤣😉😉😉

Very nice !
Very very… 👍

How long would it take to charge the phone completely with the 2 cylinder Stirling?
Thank you for watching!

assuming the phone battery is 3000mAh, the charge current is 0.05A
battery charge time calculator says it will take
63.2 hours
Wow! That’s a long time to keep that flame going! I think we would definitely need a larger more powerful engine to make it feasible…
What about using a step up transformer?
Well, a transformer that increases amps would decrease voltage. Likewise to increase voltage would reduce amperage… I think. And as I was at the minimum voltage for the phone to recognize, I didn’t think a transformer would help. I could be wrong…
What about a backup power pack?
To charge the phone? Wouldn’t that defeat the purpose 😂
