we use these here in greece since 5000 bC
old technology rules
We actually have to test the shipable for a year just like all our other stoves so please be patient. another issue came up in the initial testing and that is we have to go to higher temp materials (3500 degrees or there about's) We burned the high temp enamel from our stove thermometer. so we need to get higher temp stuff. I do have a bit of an offer for someone who has lots of money and wants to pay Erica and i to build a special testing system. that person needs to be able to take data and let us know how the system works and if they are happy with it or dont like it. this will be negotiation as we choose who wants this. one warning its not gonna be cheap to do this and i am picky about who i trust prototype systems to. if you are interested please email me and we will talk. there will also be phone conversations and such later in the process.
the prototype has ceramic fibers and rice starch for stabilizing and that when its fired the rice starch is' burned out and you have this kinda felted ceramic that stays in place'
This sounds good. It sounds like a solid pipe of low density ceramic kiln brick... but fuzzy? I assume that fuzz would have good effect on turbulence, but I wonder if it also could create drag. Is the thinking that the high surface temps would create a thermal 'flow'past the rough surface of the inner wall?
I can visualize a type of plumbers material called carbon felt - the sales demonstration for it involves covering your hand with it and then using a propane blow-torch to melt a (Copper clad Zinc) penny ! This felted material will not however take the heat we need 'ceramic refractory material' to take ! If we admit we are speculating, then think of one of those new micro-fiber blankets or 'throws' now on the market. While they feel felt-like, they visually 'look' smooth and sleek ! Again this is all nearly useless speculation, and may be harmful if we start using words to describe " VAPOR WARE " we have never seen ! Lets not be guilty of seeing clothes on a Naked Emperor , and then trying to describe them !
I'm sorry if this was confusing or misleading in any way. I guess I was just taking a stab in the dark and hoping that Erica or Ernie would fill in a bit more of the picture. I can also understand why they don't want to spotlight too much of an ongoing project.
There are so many good minds and deep experience on these forums; I find I get a lot out of people's purely mental constructs. I will clearly label mine as such into the future.

. You can follow this yourself by going to Paul Wheaton's Pod cast #225 , and listening to Paul W. and ernie and erica Wisner (stewards in these forums) discuss the new rocket stove Mass Heater's Trial Run -
. They give the credit to the improvement in performance to the new Heat Riser - The BAD NEWS is they want to test this for at least a year before they release the new parts to Production / Sale !

in different sizes and shapes. My plan is to locate and purchase a couple of these to build a smallish cooking
Rocket stove. Did anyone else see the German cast ceramic core I found on EBAY ? Look back a few messages
in this thread and there are two photos.
We will be trying to also get some folks trained up to do installs for folks who CANNOT do owner builder duties. when the testing is done on the shippable cores We will splinter that off to another person.
The materials for the shippable units must be tested for a year (sorry folks but its why my stoves work well). We cannot hurry this along, Paul asked us to show prototypes and we have done so but it also means everyone will have to wait till I am satisfied with the durability and burn results.
love you all and please dont fight over this.
Erica and I are working as fast as we can with what we have.
I for one would still like to see some sketches / pictures if possible ! Pyro -Allen L.
Refractory means it has mostly insulating properties, ability to handle hi temps. light weight and not as durable to abrasion
Ceramic means durable, usually hard 'rings like porcelain' able to hold high temps traditionally made from clay
the only thing that they might share in common is made often made by high temp processes
If this isn't right , than color my face red !
finally logged in, I have lurked for a while on this and other boards.
Thanks to all who have shared their expertise.
I'll have some insights to share soon on my casting efforts.
In the mean time, Nate shared this on another thread and kindof let the cat out of the bag...
Those are the largest trousers in the world! Especially when next to this ad:
