Rocket Stove Mass Heater. A Rocket Stove Made From a Five Gallon Metal Bucket. The principle behind a rocket stove is simple–rather than cooking on an open fire, you burn wood in an insulated chimney.
Rocket stoves are highly efficient and easy to make. They run on twigs, so you can avoid cutting down a whole tree just to cook dinner. We’ve had a rocket stove made out of brick in our backyard for several years. The post we wrote on it in 2007 is–oddly–the most frequently searched post on this site. I figured that since there was so much interest in the topic it would be good to offer one that didn’t require masonry work. Using a piece of 4″ vent pipe and a 90º elbow, I made the chimney. I traced the outline of the vent pipe on to the lid of the bucket and cut this hole out with a jig saw. Using the vent pipe as a guide again, I cut out a 4″ hole near the bottom of the bucket.
I used one part clay (harvested from the yard) to six parts vermiculite as my insulation material. I found a barbecue grill at Home Depot that rests on the top of the bucket to support a pot. Recent Research On Rocket Mass Heaters (& Bell Design) There appears to be a huge amount of traffic and discussion through different internet forums about rocket mass heaters and reports from the authors on sales of the book on the subject confirm this incredible surge in interest.
I am quite certain that this excitement stems from the tangible possibility that the rocket mass heater concept offers to individuals and families to build their own affordable efficient wood-fired heating system. I thought it would be interesting and useful to offer the following synthesis of recent research I have been directly involved in and links to information that others have provided to feed more fuel to the fire of this interesting global conversation. Article Table of Contents: The Difference between Rocket Stoves and Rocket Mass Heaters First, a clarification regarding terms may be useful. The Book on Rocket Mass Heaters There is a wonderful book on Rocket Mass Heaters. The MHA Experience Construction Processes with Commentary Conclusion: Suggest a link! 14 Bright Ideas For A Better Wood Stove. The 14 finalists for the Wood Stove Design Challenge will be formally judged during a weeklong Wood Stove Decathlon at the National Mall in November, when a team of stove, air quality, and combustion experts will select the winning stove based on five criteria: emissions, efficiency, affordability, innovation, and ease of use.
Throughout the challenge we'll see plenty of innovation, but its impact could be insignificant unless we—the consumers—embrace clean-burning technology in meaningful numbers. And that's less likely to happen if next-generation stoves lack compelling benefits or are simply unappealing to the end user. Here's where you can help. We'll present a separate People's Choice award to the stove you think is the most innovative. Maybe you value user friendliness most—or perhaps functionality, practicality, cost, or even aesthetics.
