This is very clever and the heat transfer should be very good.
Zeno’s fireplaces are Dutch-designed and crafted. And although the company’s Colonna model (pictured) is not custom-built, its unique shape cast from Cor-Ten steel melds naturally into outdoor installations. Dens van Laarhoven, the company’s president, says that application opportunities are many for the 5-foot-9-inch-tall design—freestanding in garden spaces, on terraces, or, with some minor adjustments, under porches.

Recently, my father-in-law was doing trail maintenance in Southern Ohio... some land owners wouldn't allow any type of fire to touch the ground when he camped on their properties. So he could have a fire while camping, he took an old propane tank, had the top cut off, and had a few pieces of angle iron welded on for legs. Now he can take a small fire with him wherever he goes!
