A Better Wood Stove

Is there such a thing as a sustainability geek? ‘Cause I’m pretty sure I am one. Anyway I love reading about gadgets like Philips’ new woodstove, which uses a fan (powered by the heat generated by the stove) to burn wood hotter and more efficiently, decreasing the amount of wood a family needs and decreasing the amount of particulate pollution emitted. It’s aimed at people in third world countries who use wood as their primary means of cooking and heating?
