Rocket Mass Heaters and Natural Building
July 9, 2022 - July 13, 2022$750
Like two jam-packed workshops in one! Come build a rocket mass heater, a super-efficient wood-burning stove that stores heat in the thermal mass of an earthen bench. Learn about the many exciting RMH variations and possibilities: batch vs. downfeed! cooking! water heating! hypocaust floors!
At the same time, we will be exploring a range of high-insulation and thermal mass natural building systems including cob, straw bale, light straw-clay, and slipsquatch (redwood bark and clay.) We will also install the drainage layer and the first pour of an earthen floor.
Students will rotate daily between several hands-on projects so that they get to know each of these techniques. Daily lectures cover the theoretical knowledge you will need to design your own project: how a RMH works; dangers, do’s, and don’ts; thermal properties of natural building systems; and how to combine them all into an energy-efficient passive solar home.
Instructors include Michael G. Smith, Sasha Rabin, Colin Gillespie. See web site for more details, instructor bios and discounts.
