Wood-gas Stoves Made Out Of Clay! And With No Electric Fans for Drafting!

The post title says it all. I just happened to stumble upon this gem of a post:
Low-cost Wood-gas (Gasifier) stove – BEST STOVE

Potters in India are making non-electric wood-gas stoves out of clay! The wood-gas camping stove I have is very cool, err hot. And I love using it. But for sustainability how can you bit clay and sticks? No need for batteries, etc…

Now this is exciting technology!

Edit: A friend pointed out that it wasn’t a true wood gas stove. Oh well. It is an interesting design for increasing efficiency. Tough to get away from the tall chimney without an electric fan.
