@@rippleafrica1Then you can reuse the ash to make more bricks and mortar. Then once those are burnt through, the ashes can be collected and made into bricks made of a putty that truly won't come apart, even when wet. The chemistry behind it is that it's calcium hydroxide, absorbing carbon dioxide and becoming calcium bicarbonate. Once dry it turns into insoluble calcium carbonate.
This is great. I work in Mozambique and would love to do something like this for the feeding program at our preschools. We get through so much charcoal. Can you use this oven with charcoal or only wood?
Good question - The kitchens are very well ventilated and there is no chimney but because the cookstove burns more efficiently there is less smoke produced - hope that answers the question
There's very little smoke produced. The idea is that this uses biomass very efficiently--so efficiently that the existing ventilation is perfectly fine.
@@blackcitroenlove I was going to ask same question and biomass is new to me, I will ask, i want to build a pair of these in my future home in the south of Chile, it's fantastic, thanks a lot
