Hey all, thought I'd let you guys know I'm releasing some new products on my Walker Stoves site today. I'm building lighter versions of my original Walker Stove concept, rockets in a box, as it were. These are going to be spendy, and probably not for this crowd since we can build our own, but I'm excited to finally be able to just throw a decent stove in the car and take it to an event to share the technology. Not only that, but you can build around them with masonry, or use them in any system you can imagine. It's not a perfect solution, but hopefully will be a tool that can solve some problems and introduce more people to this awesome technology. I'm very early in the process of getting info and accessories and stuff up on the web, but it's coming along. If you would like to check 'em out, they are here: walkerstoves.com/walker-aluminum-series.html |

Cool! I love it when a fellow builder finally gets to this point. I trust you will do well in selling them

Thank Keith! I'm super excited about them, not about selling them, but just that I finally can get on with showing people all the cool stuff we can do with these combustion units rather than wasting time trying to hold everyone's hand just to get an engine that works. I imagine not too many people have any concept of where these things can take us, present company excepted.
I think these will be a tool we can all use to show up somewhere and just start building a water heater, or big old bell system, or whatever. I wish I were wealthy and could just mail one of these things to all of the believers so we could keep them in our cars and preach where ever we landed.
It's a start though! Thanks man, I expected deafening silence on the release, which I got....your "atta boy" is really nice, I can't tell you how much I appreciate it.

What came to mind when I seen them was the uses for emergency operations natural disasters, third world countries
With the design being in what I'd vision as flight cases for easier transportation and offer some protection against damage of the internal engine
You've came along way matt as with Alot of members
I think the sharing of info is just as impressive as the builds

Well done Matt - I love the concept of a pre-assembled core/engine. What would a 6" batch box 'cassette' & riser weigh?

Thanks Andy!
The riser is around 15 lbs/6.8 kg. Without the split brick liner, which should be removed for transport. wWith casters and handle, the whole box complete weighs around 65 lbs/29 kgs. That's with the Walker Air insert which can be easily removed and would help shed 10 lbs/4.5 kg. or so.
A Standard J is about half that weight.

Nice work Matt ! I hear you about having a straight up running example to show the folks who find these things hard to believe. If you can put a suitcase handle on one of them I'll take the walk on ferry over your way and bring one back to show the peeps  For what it is worth, i have been involved in 'air shed quality' discussions with the local regional authorities. Some of the higher ups are trying to ban wood burning altogether, and i am saying 'WAIT A MINUTE'. I have been referring them to your web site and some of the forum threads and they are gaining interest. Just another way of saying thanks for all the amazing work you have done in this realm. |

Thank you Pat. You are welcome here anytime...I think you know that. And..they do have suitcase handles as an option! Come and get one whenever you are ready!
Here's how the J looks with leather handles on both. I'm not settled on hardware yet, just hunting around for stuff, but these ones are pretty good so far.

Yeah, I think we would all do well to point out that these rockets minimise the amount of wood actually burned per unit of heat, thus the carbon footprint is significantly smaller than other sources. It would likely be a significant research undertaking, but actually quantifying the amount of CO2 produced by the various heating methods to simply heat one litre of water to boiling... well, that would be an eye opener. Solay PV, Nuclear- or hydro-electric-powered range would win hands down, but where does everything else fall into rank? I think the rocket would beat my coal-fired electric any day The revolution is started Turtle |

Ya Matt, a visit is surely in the cards  "Solay PV, Nuclear- or hydro-electric-powered range would win hands down, but where does everything else fall into rank?" When factoring in all embodied energy involved in building, operating, cost of waste disposal, danger etc.. those big systems have hidden costs. When we factor in the deeply relaxing and grounding effect of our little heaters… hidden (health) costs go down. Deep relaxation cures/resolves all kinds of disease... |

Hi Matt,
Looks like a good concept to me! So it is an aluminum outer structure with a split fire brick refractory lining. I suspect there should be also insulation material involved. What kind do you use there and what thickness? Just curious how you shield the alu from melting...

Good job Matt. Reminds me of this, from 26th of may 2013 www.filedropper.com/easycore3I see you struggling lighting that J tube. Myself, i just plonk a bundle of sticks in there, squirt some denatured alcohol on theses, throw a match in there and voila! |

Thanks all. Duly noted Max, one for the stove one for the crew!
Peter, thank you for the encouragement. I know you well enough to take that compliment as a great indication I'm not way off.
As for materials and stuff, they are a lot like the ones we had around in Montana. The original which I cast when we were together in 2014 was a variation on the first Walker Stove construction which I took to DC. These are a bit more refined, similar to the ones that were built this year, with a bit more refinement still. So, actually, I don't build or ship them with any fire brick. The owner supplies six split fire bricks as a sacrificial and replaceable fire box liner. In the batch that can be 6-12 depending on how badly you need to jam shit in the firebox like a neanderthal, but that's beside the point. So, yeah, the insulation varies from 1" to 4" thick depending on the area.
As for the durability of the aluminum and the heat, well....I know I must be crazy because no one uses aluminum for wood stoves. However, my favorite engine of all time, the Cummins Turbo Diesel in my truck, has aluminum pistons. Corvettes have aluminum engines.

Nice job, Matt. Is there going to be a steel series? I'm guessing the Aluminium series is for demonstration purposes, not intended to have a barrel put over it?
