How to Build a Rocket Mass Heater

I am quite literally 'stoked' about this workshop my friend Andy's organizing for September 27th to 29th in Guelph.

Rocket Mass Heaters are a safe, cheap, and easy alternate heating source for those of us living in cold climates.

You basically use free, recycled, or cheap materials to build your own heater that operates on sticks and scraps of wood to keep you warm all winter. These things are so efficient, the only real exhaust is a bit of water vapor.For those that know a bit about alternate ways of heating, these basically combine the super efficient burning of rocket stoves with the heat mass principles of masonry stoves, also including a cooking surface. The cartoon above shows you what they can look like. 

So, not only will Andy, who has built several Rocket Mass Heaters, be putting this together, but he's working with the Minga Skill Building Hub and Transition Guelph to bring in Ernie and Erica Eisner, authors of books on Rocket Mass Heaters, and who have installed over 700 all over North America. These guys are stars on the Permies forums.

Tonnes more great info on the website about the workshop. It will likely fill up fast, so register now: http://rocketmassheater.ca/
