Majority of rural households worldwide lack clean cooking fuel & electricity for lighting. E.g. in India alone around 60% of rural population lives with almost non-existent electricity & uses 200 million tons/year of biomass to cook on primitive cook stoves. For most of these households the only light they get is that coming out from cook stoves! Lighting which is a basic necessity & the fundamental need of humans is missing from the lives of the rural population. Wherever there is no electricity, old & inefficient kerosene lanterns are used. These lanterns by & large produce inadequate light besides producing harmful indoor air pollution. It is estimated that 1.5 million people die every year worldwide because of indoor air pollution created by inefficient kerosene lanterns & biomass cook stoves. Lanstove™ runs on kerosene & produces very high light output (almost equivalent to 200-300 W bulb) & also cooks in the heat of flue gases, together resulting in tremendous energy efficiency.
