Would it help to reinforce it with some grid wire like chicken wire or smaller? Would that make it last longer. I noticed someone said to mix soot with the concrete ...does any one have a recipe with proportions for doing that? Are there any test results that show how much stronger/durable that will be? Tx.

Hi Greg, This one looks adaptable to India village. I'll call you soon to discuss a design for the village to try. We can possibly do a build/demo for mid-March annual day. Tx. Bob C
You need to make it a bit taller so all the flue gasses will burn before escaping. If you make it about 3' tall it will really burn clean and much hotter. Make it in stackable sections so you can still move it (very heavy) Also you can get castable refractory cement to mix with the pearlite and that will last unlike portland cement. I get mine from Thorpe products in Dallas. Keep up the good work!!!
You guys see the stove Dave made at Daves Farm he has air inlet in the floor of his shop has 2 55 gallon barrels attached to recieve long logs he will load fire it up and this Canadian keeps his place toasty with radiant head. Air in air out interior air doesn't get exchanged to keep the hot air in the shop. His video is buried in my favorites you might do better looking on his site.
I wonder how long the concrete will hold up, cement degrades at about 600 degrees F. Maybe using some refractory material or insulation at critical hot spots may prolong its use. Very interesting

Should be boiling a big pot of fermented feedstock for a Charles 804 (wink-wink, say no more)

try mixing soot into your concrete mix .makes it far stronger.

@zippojoker,
You're absolutely right about the durability of the concrete stove. It is already showing signs of coming apart after only a half dozen uses.
We'll play around with concrete some more and see if it can be made sturdier.
We built a steel rocket stove out of 6 inch well casing that will likely hold up forever. I'll post videos of it pretty soon.
We have plans for a really big rocket stove/gasification hybrid that will likely begin to be constructed this week.
Thanks,
Greg
