How to build a Changu Changu Moto fuel efficient cookstove - RIPPLE Africa 

Soil with clay is good - we use mud from termite mounds

​@@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?

Yes you can. The only difference is that you can't half bury the two bricks at the bottom of the fire holes

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

@@rippleafrica1 thank u for ur reply! It helps!

​@@rippleafrica1And the taller the stove, the bigger the draft-and the less smoke it emanates! Changu Changu Moto is basically a rocket stove!

Here is a copy of a step by step guide www.rippleafrica.org/wp-content/uploads/2016/03/Changu-Changu-Moto-step-by-step-guide-Feb-2016.pdf good luck!

😂😂😂😂😂 oh my God you made me laugh. We don't need the chimney. We strong african women.

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

usefull idia

it is slow and inefficient. Takes about 25 mins to cook an egg. It's more suitable for grilling, not for stir fry
