I have two. One is a larger one that I picked up for free that someone who has a plasma cutter made as a project then just got tired of it taking up space. It’s about 4ft tall and sort of shaped like the Eifel tower. Just before I found the big one I bought a smaller portable one from Amazon to throw in the truck for camping. It’s compact but heavy. Camping Rocket Stove. It was quite a bit cheaper when I bought it a few years ago. We have enough trees that cleaning up sticks is nearly a full time job so I don’t worry about running out of fuel for them.
