Fumes from indoor cooking fires are responsible for more than 2 million deaths every year in the developing world. But by simply turning their farm waste into a cleaner burning fuel it may be quite simple to make that dire statistic a thing of the past.
Materials needed:
- Corn cobs
- Drum, 200-lit. capacity
- Sprinkler
Procedure:
1. Place the corn cobs inside the drum about 1/3 in height and burn until the smoke disappears.
2. Fill the drum additional corn cobs (about 2/3 in height) and burn again until smoke disappears.
3. When the smoke ceases, empty the drum.
4. Sprinkle water into the burnt corn cobs.
5. Spread the cobs for drying under the sun.
6. Separate the charcoal from the ashes.
7. Store.
