What's Not a Rocket Stove?  RSS feed

I got into rocket stoves a few years ago after reading about Ianto Evans and being somewhat frugal by nature, I thought it a beautiful design. I read up on Larry Winiarski and the history behind the design and was impressed by his motive to improve upon traditional cooking arrangements in the third world . I've not got around to building one yet, but my brother did using the PDF I bought from Ianto.

The thing is this, I have now seen a number of people on YouTube, forums, Ebay and elsewhere who declare their stoves as rocket stoves that are usually missing the one element that I understand to be crucial to the design: a highly insulative burn chamber and flue to optimise burn temperature. Two examples can be found here:

I can't see that either design could possibly burn efficiently enough to warrant the label rocket stove, but I'd be happy to be corrected. What do others think?

Joe Higgs : a little history -

Rocket Stoves were invented to replace the poorly balanced cooking pot setting on the 3 - ROCK FIRE used indoors and out doors by approximately 30% of ALL the
people on the planet ! This was a greatly less smoky fire, that used fuel more efficiently, and reduced the large number of pneumonia type illnesses and cataracts among
groups adapting these technologies in third word countries ! ( Following this line of research is what brought me to Permies.com)

Pocket Rockets, Are also intended to be used exclusively out of doors, and burn so very hot at their base they have been known to 'set the blacktop on fire ' they are very good
for Picket Lines, Preppers and Zombie hunters! And Boy Scouts and Ice Fishers ! Use is totally out of doors ! - And they use a lot of fuel ,sending much of their heat energy up
the chimney, just like conventional Wood Space Heaters !

rocket mass heaters R.M.H.s, Burn wood fuel at very high temperatures and very efficiently! The trick here is that R.M.H.s create such a combined 'draw' that the hot exhaust
gases can Flow horizontally through 30+ feet of ducting before being ducted to the outside of the building ! The use of a heat storing or THERMAL mass bench is the 'secret'
behind the creation of the super efficient and wood stingy R.M.H.

There is nothing in the original Rocket Stoves creation, that was centered around a more efficient way to introduce fuel and air flow together on a narrow and quite limited flame
front that would have lead automatically to a Heat Riser , this was a latter development which needed the further development of a Thermal Mass Storage Device to create the
"RocketMass Heater'' ! So -


1st) The rocket stove, for cooking and feeding your family on less fuel, and with less 'environmentally caused disease and damage' than the 'Traditional 3-Rock 'Fire !

2nd) The Pocket Rocket,for heating all outdoors, loved by outdoors people ,Scouts Ice fishers !

3rd) The R.M.H. For heating your home efficiently and on less wood, and feeding your house Dragon !


The use of the term "Rocket Stove'' As a generic term for all forms of wood burning stoves in this family is unfortunate and is even contributed to by this
Permies.com Forum, and Forum Threads which directs you to 'rocket stoves and (rocket mass heaters,)' rather than the other way around !

I hopefully suggest that you retrieve Your copy of Ianto Evans' "Rocket Mass Heaters " from your Brother and re-read it, Most of the information I have shared
is clearly stated within these pages, I have probably read and re-read 'The Book' multiple times and can still glean facts with every reading ! For the Craft !

As always, your Comments and Questions are Solicited and Welcome Think like Fire!, Flow like a Gas!, Don't be the Marshmallow Big AL !

Why did you think I needed a little history (and lecture) when I stated I read the history? I should also add I have a Stovetec rocket stove that I use. Shrug/

I thought it would be an interesting topic to cover, given that Permies is a meeting place for folks into rocket stoves and because I was baffled at how so many people didn't grasp the design principles of the rocket stove and clearly hadn't bothered to do any research. A simple search in YT with the term rocket stove will illustrate just how many people are confused about the design elements. Mostly they tend to think a L or J tube shape in whatever material is enough and that information gets passed on unchallenged. I found Winiarski's idea of saving lungs and lives as well as fuel on such a grand scale to be totally brilliant and feel his invention needs to be preserved and passed on, but instead was finding more and more half-arsed designs being sold as rocket stoves that couldn't possibly offer the benefits that Winiarski intended.

Joe Higgs : O. K. ! Sorry I missed your point, Restating the merely obvious, doesn't help you at all, however re-stateing the history is a story that presently needs any excuse to
be told ! I Will never apologize for preaching to the choir, the more they hear the 'old,old story' the greater their understanding, you just handed me the forum on a Silver plater!

It's fine. Obviously you're as frustrated as I am with all the brick mounds and ironmongery being passed off as RS's
 
I do some of my very best work in water. Like this tiny ad:
