Over 820 million Indians, about 65% of its population, cook on polluting open fires, causing ~1 million premature deaths annually. Fifty million households have no electricity.

The Power Stove is a household energy solution combining clean cooking and reliable, ondemand power. Clean combustion and thermoelectric power technology, make it a high performance, user desirable solution based on low cost thermoelectric modules generating electricity from the stove during cooking.

It supports a family of eight delivering 65% fuel savings and 70% smoke reduction while generating eight watts of power. One day of cooking will charge two cell phones and provide light for four hours.

Hi-Z, a thermoelectric company and Greenway, an established Indian cookstove manufacturer, plan to introduce a power stove to rural Indian families.

Phase 1 demonstrated a 35% efficient “power” stove that produced 8 watts of net electrical power and reduced emissions and cost. Phase II R&D will ensure the cost will not exceed an affordable $25. Further R&D and field trials will be conducted during Phase II to obtain and implement market feedback.

The Power Stove will revolutionize the lives of rural Indian families by improving their health, lighting their homes and connecting them to the modern world.
