So I’ve been trying to improve the rocket cookstoves that I use at the cabin (like the double burner Rocket Chuckwagon
https://www.youtube.com/watch?v=gJ3FH7UPYjY). I made the Ottawa
Rocket Stove Scale (
https://permies.com/t/51099/rocket-stoves/Rocket-Stoves-Free-Tool) based on Winiarski’s basic principles and that helps me to score a design before I build it to assess if it’ll be any good. An easy miss in the design is not to incorporate a pot skirt to keep the heat close to the pot that is being warmed. I’ve made this mistake and looking around the internet I see that’s it’s pretty common.
Luckily the bright folks at StoveTec have come up with a solution
(
https://stovetecstore.net/product/stovetec-super-pot/), a double-walled cook pot that essentially forms a chimney around your pot to increase heat transfer. It also makes for cleaner hands as the charring is on the inner walls rather than the outside of the pot.
In the spirit of doing things yourself and building from trash, I put together my own Super Pot for my rocket stoves. Here’s a how-to
video of how I did it.
