Ideas That Change Lives

Enviroft Clean Stove
"More than half the world’s population cooks over open fires or small charcoal or biomass stoves. These burn fuel incompletely, producing carbon monoxide and smoke that cause 1.5 million deaths a year. Envirofit’s Cookstove burns the same easily found wood but does so more completely to cut emissions by more than 80 percent and use half as much fuel. The can-shaped stove has a precisely measured opening that lets in enough air to fan the flames, yet not enough to cool it and slow down combustion. A chimney-like tube inside helps funnel in fresh air, and a ceramic lining insulates the stove to keep the fire hot and burning efficiently."
