Anevay got started designing portable stoves for the humanitarian aid world and disaster relief. The brief? 50% of the world’s population still cooks on open fires, and deaths from respiratory disease due to open fires and dirty fuel outstrip malaria and AIDS combined. We designed the Frontier Stove to combat these problems: the closed firebox means more efficient use of fuel, crucial where wood is scarce, and the long flue transports fumes away from the cooking area. Tested to the limits in a variety of disaster situations, the stoves were essentially life-saving devices for the people receiving them.
