Join permaculture innovator Paul Wheaton for a presentation on Rocket Mass Heaters (ultra-efficient, wood-powered heaters that store warmth in a thermal mass and dramatically reduce fuel use and emissions.)

After the talk, there will be a Q&A  session to dig into your designs, builds, and “will this work in my place?” questions.

All are welcome! Hot tea provided (and feel free to bring healthy yummy perma snacks!).
