I just remembered that I have stored somewhere a gizmo called, I believe, the Safari Cooker, or something like that. The TV ads of long ago touted it for tailgate parties. Several tapered sheet metal sleeves that go together, along with a couple of grates, to make the stove. Fuel is, believe it or not, sheets of newspaper, crumpled into balls. Nothing else! It only takes something like nine (9) sheets of newspaper to BBQ a few hamburger patties! Newspaper, now that is a save fuel to store. Sadly, you can't even find them on E-bay (or at least not the last time I looked). But that little thing actually works, and works pretty well...
