I had plans of uploading the video directly so you wouldn’t have to follow a link. Sadly however the device I recorded it with bricked on me and I’m not paying youtube for the privilege of downloading my own video.
Anyways, this shows how I prepare cans to start making heat risers for pop can solar heaters. I’ll eventually put together another video showing how to put the cans together to form the risers themselves.
I’ll also likely put out a small reasonably priced booklet if there is enough interest in such a thing.
Best of luck in your ventures.
