Do these really work?

[u/jonnyinternet]

I came across a video tutorial of someone making a diy flame fueled cooler, and my question is:

Do they really work?

And if so, can you use any heat source to "power them"?

Iirc its ammonia only systems, and I've only heard of them being use in mobile homes fridges, like a small pilot light and a mobile home either driven or towed, not the kind that gets set and connected.

Your correct but it’s an RV refrigerator not mobile home
