The Hybrid Solar-Biomass Cook Stove is an innovative efficient wood stove that also incorporates a solar reflector. It is the invention of Dr. Arvind Chel of the Center for Energy Studies, IIT Delhi, India. Research is being done in cooperation with Duke University, USA, under the umbrella group of Mango Solar Energy Service.

The Hybrid Solar-Biomass Stove burns all biomass varieties, including wood. The combustion chamber focuses the flame and forces the gases to mix with the flame, which increases efficiency and decreases harmful emissions. The solar component consists of an insulated chamber that fits on top of the biomass stove and a solar reflector that sits on top of this chamber to direct sunlight inside. The combination of these technologies will reduce fuel costs and harmful emissions.

The hybrid solar biomass cook stove is user-friendly and will provide the flexibility to use the solar component during sunlit daytime, and biomass during night time, independent of seasonal variations. This novel cook stove can make fried food products, which is not possible using box or panel style solar cookers.

This clean efficient cook stove has enormous potential in Indian villages which are suffering from inefficient biomass cook stoves. The target customers are spending daily Rs.12 to Rs.25 on cooking fuel daily. In contrast, the hybrid biomass solar cook stove requires daily Rs.6 to Rs.12 for biomass fuel. A prototype stove is currently being built at Duke University.
