We introduced the fuel-efficient cookstove in Africa to communities in Malawi to provide a safer and more sustainable alternative to the three-stone fire. They are known locally as the Changu Changu Moto (Fast Fast Fire).
- Three-stone fires use three to four bundles of wood each week
- This amount of wood takes three to five hours each week to collect
- Three-stone fires produce a lot of smoke
- Children are more at risk from burns
- Each Changu Changu Moto fuel-efficient cookstove uses only one bundle of wood per week
- It produce less smoke and the fire in the cookstove is contained and is therefore much safer with less risk of burns
- The cookstove benefits from being a double burner
- It is cheap and easy to build

Fuel-efficient Cookstoves in Malawi, Africa
Achievements and Future Plans
So far, we have helped communities construct over 47,000 Changu Changu Moto cookstoves and have supported the householders to maintain and use them. This has resulted in 94,000 fewer bundles of firewood being needed every week, reducing household wood use by 67%. With additional funding, we hope to provide more Changu Changu Motos to expand the project.
How We Work
Local community volunteers for each village are trained and then work with the communities to build a Changu Changu Moto fuel-efficient cookstove in each kitchen. Each house is regularly monitored and householders are trained on maintenance and wood use, and the information is recorded on a database. We continue to monitor the households to make sure that this simple technology becomes a way of life.

The Project's Future
Deforestation in Africa is a huge problem, but we believe that the use of our fuel-efficient cookstoves in Malawi will help save millions of trees. We expect that every stove built will continue to be in use for an indefinite period of time. With the longer monitoring period, our hope is that any problems are addressed during this period, so the stoves will be in use well into the future. Householders are taught to care for, repair, and even replace their stoves, so the outcomes from the initial investment will carry on for years to come. We have also helped families to plant their own trees which can be coppiced to provide a sustainable source of fuel close to where it is needed.

Children regularly suffer burns
from falling into three-stone fires
or when their clothes catch fire
Less smoke is produced, the cookstove
is safer and cleaner, and it benefits

How to Make the Changu Changu Moto Fuel-efficient Cookstove
Anyone can build their own Changu Changu Moto fuel-efficient cookstove, and we encourage people to copy our design! Just follow the instructions below or download our Step-by-Step Guide on how to build one.
First, 26 mud bricks need to be made
and dried in the sun
Collect clay soil and sandy
soil to make the mortar
Prepare a place in the kitchen
to build the cookstove
Once the cookstove is built, mud is plastered around the exterior
Mud pot rests are constructed – a Coca Cola bottle is used as an example for sizE
It’s ready for use in two to three
days when the mud has dried
