Philips Wood Stove
The Philips wood stove is made out of stainless steel. The airflow through the burning wood gasifies it and these gases are burnt with preheated secondary air. This results in cleaner burning and more efficient use of the fuel.
The efficiency of this wood stove is based on the stove having a fan that forces a controlled airflow through the stove from below. The fan improves the fuel to air ratio, helping the stove reach cooking temperature in a short time. The regulated airflow makes the heat output more stable and controllable.
When the stove is lit, the fan runs on a rechargeable battery. As the stove temperature rises, a thermoelectric generator slowly takes over from the battery to power the fan. When the stove is at its highest temperature, the generator also recharges the starter battery. After initial testing among 24 families in India, Philips Domestic Appliances and Personal Care launched a commercial pilot project in 2006 in Maharashtra, Tamil Nadu and Uttar Pradesh, which ended in February 2007.
Knowing this stove can benefit people in other parts of the world, Philips is investigating opportunities in Africa, China, and Latin America. It remains a challenge to find durable low-cost materials for the fire chamber.
