[Stoves] Charcoal production, improved

[Юрий Юдкевич]

Dear Chris ADAM,

We had personal correspondence and it seemed to me, that I have 
explained a state of affairs honesty. I regret, that you offer your 
technology as non-polluting and economical repeatedly. We spoke about a 
real output of coal from wood. I think, you could look standard 
scientific manuals before to announce an output of 40 %.
I regret
