I’m not sure how useful this firewaall (and, no, I didn’t spell that wrong) is for survival purposes but it does have some potential applications as a nice camp out conversation piece, lol…
“OK, in all seriousness, the old-fashioned campfire is just fine in most situations. But a Canadian company just launched a new contraption called a Firewaall. It’s pretty neat.
The made-in-Canada apparatus simply holds wood in a wall-like form. Start the fire with tinder in the bottom, add some larger sticks, and enjoy a vertical blaze.
What’s the point? Good question. First, the Firewaall contains fire in a way that looks pretty efficient. The vertical nature of the wall helps it radiate heat outward. It elevates fire too, which would be nice on a frozen lake…”
