I built this Rocket Stove from scrap metal to serve as a daily use wood stove at a training center. I wanted it to be long-lasting, efficient, and work well, and be able to use various fuels including scrounged branches, wood chips, split wood, and eventually pellets.
I loosely based it on a model made by Vendel Keresztyen seen at http://youtu.be/k5szviNZZP8. It has a gravity-feed hopper as well as the traditional horizontal feed. The pot can be placed on the insert directly over the fire, or on the grill with the hole cover either in place or removed.
You can see that it burns well and produces little or no smoke. I’ve run it on twigs and branches, wood chips, split wood, and pellets with good results. Since branches are abundant and free at the center it will likely be run mostly on those.

Great job. Love it. This is one of the best stoves I’ve seen lately. It seems to have everything. It’s very versatile, and simple enough for DIY fabricators to build. The rave reviews confirm my hunch that this is a highly marketable design. Many commenters said it’s the best rocket stove they’ve ever seen. Basic dimensions are given below the video at YouTube.
