the current state of the art, in one convenient volume. Erica and Ernie are also accessible via the Permies.com forums for lots of follow-up support and brainstorming. With grit and by grace, rocket mass heaters will begin to replace other heaters wherever appropriate, which will drastically increase comfort and decrease pollution and fuel use.
People are already designing combo rocket (mass) heater/cookers (including grilling and smoking), which should render charcoal obsolete wherever trees grow and stick fuel is available.
This book also clearly describes how the heater is not appropriate for my current living situation...so I will have to wait until I move (since I'm not going to undertake a major remodel -- I have wood floors and a basement). If I was going to stay here forever, I'd solarize my south with an attached greenhouse and rocket thermal mass bench. Having a clear understanding of design parameters helps unleash the systems-level design creativity!
