Rocket Mass Heater and Emerald Earth, Boonville, CA, USA

 

 

     
 
 
 


This rocket mass heater is in one of the homes at an intentional community in Boonville, CA, USA called at Emerald Earth. The rocket mass heater is an ingenious design that consumes all manner of awkward bits of wood converting them efficiently to heat that winds its way through a cob bench. Because the bench has so much mass it acts like a heat (thermal) battery keeping the room warm for many hours.

 
 
 

 

 

 

     
 

The video with the picture above is a tour given by Michael G. Smith, a resident of Emerald Earth and co-author of The Hand-sculpted House. You will see the stove, with a brief explanation of how it works, at 3 minutes 20 seconds, however the whole video is well worth watching giving a nice introduction into different natural building techniques. If you would like to build with natural materials you can find rocket stove and natural building workshops here...
