The ebook is now available here for purchase at Scubbly!



We are very excited to announce that Tim Barker and Joel Meadows have just released their new book, The Rocket Powered Oven. This practical, hands-on how to guide will run you step by step through the process of building your own rocket stove oven, with two different types of designs to choose from.




You may remember Tim Barker from our big event this past summer - he was the instructor for the Appropriate Technology course.

Tim has come a long way since his days as a diesel fitter mechanic, and now spends his time between Australia and New Zealand (and sometimes the US) as a semi professional pyromaniac and mad scientist, teaching people how to burn stuff and make really cool machines and devices for low carbon living.




Joel draws on a deep well of experience (as an energy auditor, sustainable transport consultant, environmental educator among other things) which he combines with a rare knack for explaining technical issues in a clear and engaging way that cuts straight to the heart of matters. Joel has just finished owner-building his permaculture-designed property and strawbale house which features impressive passive cooling, heating lighting and water strategies, rocket stoves for heating and cooking, and a beautiful curved roofline that follows the path of the winter sun.


Here's a look at the Table of Contents for the book:

! Imitating his conversion of a conventional wall mounted oven to a rocket powered one is my grail quest!

Are there going to be a solid real time copies sold, or just an e-book?  I read enough online.

No plans for a physical book at this stage. If there is, it will be available from the product page for the Rocket Powered Oven on the Permaculture Principles website.

The designs in the eBook are for a barrel oven and a conventional gas / electric oven rocket stove retrofit. I attended Tim and Joel's workshop (in Australia) and it was awesome. I too had a dream of converting a conventional oven, and hope to do one at my place in the next month or so. I've got the oven! The idea of heating up my home during summer seems crazy - an efficient outdoor oven is the way to go,

This image is from that workshop and features in for January in the 2017 Permaculture Calendar.

I give the book 9.5 out of 10 pizzas.   As expected from Tim Barker (a great mate to have a brew with after a day of building permie stuff) it is a no nonsense this is how it done instruction with not much more than an angle grinder and a pop riveter.   With all the materials stockpiled probably an easy weekend project (for sure if Tim was there helping).  You can kind of tell Tim is not from around here with all the measurements in metric and terms like "star picket or waratah" but still totally readable and executable. 

The only thing I would have liked him to have shown his detailed design for his self contained J rocket stove design that he had built several of at the wheaton labs.  It was brick with insulated fire board over it. an angle iron frame, with aluminum sheeting slipped in-between the angle iron frame covering and protecting the softer insulated fire board.  A slick and multi-purposing design that could be used for an oven like here or repurposed to drive a water heater design like we did at the AT course last summer.  

Overall a book that can have you rethinking your oven requirements and for the price you should check it out.

PS
Just because you can get the oven up to almost 1000 degrees F, it does not mean you can flash cook frozen pizzas as the outsides will burn before the middle is thawed and cooked....this is how Tim was banned from cooking at the AT course...

1) Cut or break the frozen pizza into quarters first. That gets it to cook faster if you have issues with center not done enough, just place the pieces with 1/4" to 1" spacing. 
2) 1000F *IS* a tad bit excessive for flash frying a pizza.
3) Try a cast iron frypan with a viewable lid to put ON the surface not IN the oven
4) Yes I was in college and spent my wayward time with a burnout oven and kilns around. If someone was firing a kiln the frypan on top of the kiln worked pretty well after breaking the party pizza up. Double or triple potmitt MANDITORY to handle the frypan.

Yes, I'm buying the ebook on the third, as I'm pretty broke right now. Looking forward to a good read in about a week.  Merry Christmas and Happy New Year everybody.
