Re: the White Box Stove...

I watched the YouTube video of the guy reviewing the WBS, and my brother said they look like they were made from some kind of beer can that is heavier than a regular Coors (etc) can. He said he has seen heavier aluminum beer cans that sort of look like aluminum bottles with a neck. Looking at that review video, the inside is smaller than the outside.

Is this true? Is there such a thing? If so, can you give brands?

The WBS maker's site says its made from "recycled materials". WHAT recycled materials?
