I see some rocket stoves are in an L shape and yours is in a J shape. I can see the benefit of the J shape being that gravity somewhat pulls the wood in as it is burned so you aren’t constantly needing to feed it, but being able to feed it at your own pace with an L shape allows you to adjust the heat and fuel consumption. Do you like the J shape? Also, does the handle get too hot from use that you have to let it cool down before you can move it? I like the impossible to break design.
