Well now, if you understood anything about TLUD gasifiers you'd realise 
how wrong you are in that.

If I want clean tar free gas to run an engine I would doubtlessly use 
such a gasifier.

 BUT in this situation I want charcoal from the simplest possible 
device, without stinking up the general surroundings with smoke and 
without sending CH4 into the atmosphere. I'm not presently interested in 
the gas it produces, as an energy source. If I was it would be built 
differently and more elaborately. So at present I just want to flare off 
the gas.

And I'm not interested in selling it to people, I place it into the 
public domain, with a Gnu GPL type licence, if you like. Anybody can 
build what I've done and on a number of scales, from a 20liter oil drum 
to a 200 liter oil drum, to something much bigger. The stove developers 
are building them from tincannium for use in 3rd world countries. And I 
got my ideas from them.

Anyone who uses this simple concept can make enough charcoal to improve 
his garden, without having to pay inflated commercial prices and without 
annoying his neighbours to any great extent.

secretive bloatware.
