Wow! That's some quick work.
Well a picture of an image with a quick comment to the YouTube ad for the thing ought to be kinda suspicious…
Nah, I honestly did find this in an ad from one of those shitty Chinese crap sites and had no idea what it was because the text, as it usually does, only said "make great deals 80% off", omitting information about the product, the low quality workmanship and generally horrible working conditions of the poor workers producing the shit.
I just thought it would be a curious shitpost because the contraption made no sense to me. I'm guessing the commenter above did a reverse image search.
Nah I've got something similar - not exactly like this but the glass tube with heat exchanging mesh and space underneath for a burner is pretty distinctive - then searched "Stirling engine heart arrow" and tons of these came up
I've no clue what I've found
Not a bow, thats for sure. Might be a wood plane.
This is the worst post I've fucking made isn't it
Worst post, so far. ☝️
That's encouraging. Thanks!
Is that steel wool in the front? Probably a science demonstration. If you quickly increase pressure in the air vessel up front by shooting the bow, the temperature spikes up enough to ignite the steel wool.
The "string" is a metal beam tho. No bow action here.
it's a spring https://youtu.be/imRfb1ZTjF0
Oh dats cool :) Never seen an engine like that. Its impossible to see in the picture, so thanks for sharing!
yeah the photo is weird, it doesn't even look like a low resolution photo of a spring it really does just look like a rod
BOW BOW
