[Stoves] Charcoal ban is it the charcoal---

[Cookswell Jikos]

Funny enough - we once showed this company, Ecofuels Kenya, how to make
wood vinegar (condensed smoke from the charcoal making process) and they
have certainly taken it to the next level -

as they now are the lead supplier of this stuff in East African
horticulture industry and make hundreds of liters a month.

They have shown that in certain cases, the smoke can be worth up to 15
times the price of the charcoal that it was made from.

Best,

Teddy
