It is late summer in New Zealand, and we have an orchard full of trees dropping pears. We have plans for a more permanent rocket stove in our green-house come winter, but for now we would like to be able to preserve / can the fruit for winter without it cost a few dollars in electricity each batch.
We are having two problems - the first is that it often smokes really badly. I am wondering if that is from coals clogging the air vent. Are coals meant to get into the central chamber, or stay in the horizontal side tin?
Similarly, are you meant to put the pot directly on the tin, or is there meant to be a gap made for smoke to get out?
The second is that it it burns through the wood in a few minutes, and I need a few hours of burn time. Is there another model that is easy and cheap to make and portable that has the sticks vertical?
