The many designs of green stoves

Many engineers and social businesses are working on clean burning stoves for the under-developed world. The designs run the gamut from stoves that run on solar power to burning animal waste.

The green-stoves can help the poor in many ways. The clean burning stoves can help their health, as they no longer have to breathe in fumes from kerosene or wood. They also help with safety as people in war zones no longer have to expose themselves in gathering gather fuel for cooking.

From NPR series on Social Entrepreneurs, reporter by Martin Kaste talks about the competition and cooperation between clean stove designers.
