Our Sarai Cooking system has been a great hit in East Africa. It is a
steam cooker that uses charcoal made from agricultural and urban
combustible waste. Already about 50,000 of them are in use all over
the world. The beauty of the Sarai system is that it is automatic. You
just ignite the briquettes, load the cooking vessels with food, close
the lid, and come back after an hour. By that time the char briquettes
have burned themselves out, the fire extinguished and the food ready
to eat.
