It is clear from the recent New Yorker Article and the PBS Special that we are all impressed with the improved $20, $40, and $60 stoves. But these stoves are probably in the minority as far as fabrication or adoption. We should also be improving the $1 stove. Crispin presented some improvements to the low cost charcoal stoves at ETHOS a couple of years ago. Dean focused the ETHOS Stoves Camp on "refugee stoves" about the same time.

Who is currently working on improving these low cost stoves that are affordable without subsidies and microfinance and are made in the millions worldwide by local artisans?
