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:
- Place the corn cobs inside the drum about 1/3 in height and burn until the smoke disappears.
- Fill the drum additional corn cobs (about 2/3 in height) and burn again until smoke disappears.
- When the smoke ceases, empty the drum.
- Sprinkle water into the burnt corn cobs.
- Spread the cobs for drying under the sun.
- Separate the charcoal from the ashes.
- Store.
