1. How long do you have to burn in order to get biochar?
2. Does smoke develop and how much?
3. I read that biochar is very good in a composting toilet - does anyone tried to use it? Did it help with the smell?
4. How did your soil improve with biochar? Any soil tests?
5. How much do you produce say m3 of material ratio to biochar and how much do you put into the soil (best in handfulls per square meter)? How often?
6. I tend to think that digging a hole in the ground to burn would be the best and most practical way to do it?

I wouldn't think so either. Strange. You would think that with a fire raging like that, the lower oxygen would have been sucked out of the pit and consumed by the fire too. What sort of wood were you burning? Not that I can see that it should make any difference.
I honestly did not think this thing could fail that bad
So you are planning to burn the char? Is there a reason that you want to do that instead of burning the wood? Anyway, with your welding skills you might want to consider building a woodgas generator to create your char, while generating gas for heating, for machinery, or for generating electricity.
Maybe if the charcoal burns well enough in my wood/coal stove I will build a retort and try again
