Hey Permies, long time no see! I've got some exciting news to share. After years of working towards a
rocket stove or mass heater core that I could share, I've finally got something to offer!
The Walker Stoves Super-Hot J
This core is the result of years of testing and development. I began working with the early versions of this core in early 2013 or so. During the first Innovator's event at
Wheaton Labs in 2014 Tim Barker asked me to build a core for his cooker
project, the Cockit-Lockit-Rocket. I created a simple J using refractory and ceramic fiber and Tim housed it in angle iron and thin steel.
This core became a favorite around the Lab and when we got together the next year for the 2015 Innovator's event, it was refined even more. I've since been building and testing the cores in my aluminum series and in various heaters and cookers. I am pleased to finally announce that it is ready for wider distribution and I believe is the simplest to build, highest performance, most durable rocket stove available, DIY or otherwise.
These cores are built simply with ceramic fiber board modules, the fireboxes lined with user-supplied firebricks, and are designed to be skinned with whatever non-flammable material of your choice to create your heater or cook stove. Metal skins, tile, cob, stone, brick, etc. The material is extremely well suited to use with cob and masonry, and a beginner can easily stack the core, cover it with cob, and have a heater with very little fuss.
I'm offering a special through this month. In August you can get a Walker Super-Hot J for $449 shipped.
Thanks for letting me spam you good people! I will have some videos up soon of how to create stoves using these cores, and some guidance on ceramic fiber use in rockets for you DIY'ers.
