We have the StoveTec Rocket Stove which is a vast improvement in looks over our homemade stove. Homemade versions have been around in the camping and "hippie" world for years and years. Commercially made rocket stoves are newer on the scene. The designs seem to get better every year, which of course makes sense. I'm not pushing for any particular type, but it is in your best interest to either make your own rocket stove or purchase one.
