>>1066384I think I'd probably make a cover out of sheet metal/old cans to go over an existing canteen/pot. That way it could be placed over the vessel and fire to direct the full flow of the fire around the vessel. If it were doubled walled, it could have rockwool insulation between the walls to make it even more efficient.
Though, I have a rocket stove, so all I'd need to do is use a stainless steel water bottle and set it down inside the flue of the rocket stove....which I already have 2 bottles. One I turned into a water distillery using the same thing (pic). Though, copper-tasting water is fucking horrid, I can at least use muddy water to make clear water. That stainless bottle being used to catch the water in this pic would work easily in the flue for regular water heating.
