Cooking at the bottom of the pyramid

The World Health Organization estimates that 1.6 million people die each year from toxic indoor air. The main culprit is carbon monoxide released with smoke as a byproduct of incomplete combustion, when using traditional stoves.

Given that nearly half of the world population and 80 percent of rural households cook with traditional stoves, Environfit - a Colorado-based organization - saw a commercial opportunity and created a line of clean-burning ceramic stoves. Their first target demographics are Indian women. Prices will range from $10 to $200.
