LH- Less is more -"if it works"-.why have unnecessary parts?
Do you have any unnecessary parts on your stove?

LH- I have been designing and prototyping stoves for quiet a while. I am 
mostly interested in natural draft burner designs. I have not tried to 
marked a household size stove because the price needs to be so low it would 
take mass production like you are doing.
I do have a commercial duty wood or charcoal fired stove that heats a 40 
quart pot. I hope to have a video in a month or so.
>From what I could see which is not a lot, it looked like your natural draft 
stove had better airflow for secondary combustion, than the other ND stoves 
which I have not seen that well.

I hope you succeed,
Lanny
