Rocket stoves have been around for a long while. I went ahead with a large prototype build recently. It burns hot and is very efficient. It takes a few minutes to fire it up using twig biomass or kindling. The feed tube is set at a 45 degree angle and is self feeding. They call these a rocket stove, because of the rocket sound it emits from the tube when it gets going.
I plan to build these in a smaller design for camping and ease of use. I will update as they are completed. If interested in your own rocket stove, give me a yell.
Thanks for looking!
