Jon and Flip Anderson have been working with stoves and ovens for some years now (HPP regulars may remember their rocket powered oven design.) Last February, they helped teach at the Winter Stove Workshop put on by Aprovecho and InStove. Aprovecho Research Center (ARC) was consulting for Mercy Corps in East Timor, who had sent their Program Manager for Renewable Energy, Will Baron, who has responsibility for all programming related to energy, poverty, lighting, electricity, appropriate cooking technology and sustainable cooking fuels.
Mercy Corps’ East Timorese stove program imports stove components from China and trains locals to make and sell completed stoves as a business opportunity, and as a way to improve health and air quality and reduce deforestation. But the stoves were more expensive than most people could pay, heavy, and expensive to transport. So Mercy Corps brought in Jon and Flip as short term consultants to help make needed improvements.
The first challenge was to develop a stove that locals could make — and fire — into a more durable, better insulated (and thus more fuel efficient) stove that wouldn’t fall apart while being trucked over bad roads. The second challenge was to design a prototype institutional stove that could also be produced locally from local materials. The first request required building a kiln to fire stove parts, and this is what we’re sharing with you here: a two burner rocket-powered kiln capable of reaching 1,000Â° Celsius — and made of local clay, sawdust, and wood ash!
Here is Jon and Flip’s wonderful slideshow on the building and firing of their rocket-powered kiln, complete w/very detailed construction sequences:
The project was under the auspices of Mercy Corps, but the links I had no longer seem to be working! (If you find ones that work, let me know!)
