I know you don't use much heat in the south west, but I believe there is a market for some rocket stoves. There is all kinds of varieties out there and I am building a cast core mass heater. There are only a few people makeing the steel versions and are pretty simple to build. Just have to find some hippies with money or preppers who have lots of money. With your welding skills and ingenuity I might buy the first one for my yurt I will be putting up in NM.
Is this rocket stove a wood stove that pulses ?
I'm a wood stove freak and modified an Amish water heating wood stove.
The first night I used it it almost burned down my cabin.
I woke up early AM and closed the air intake down and was woken an hour later with a 70% cherry red wood stove that was pulsing like a WW2 German Flapper jet engine without the flapper.
Never seen anything like it. It got so hot it burned the paint off the walls close by and cracked a window 4 feet away.
Stove was simple. 16" pipe, 32" long, flat end plates, 6 inch flue exiting horizontal on end plate. 12" diameter door with sliding sheet metal vent about 2" X 3".
It would burn the wettest wood when even gently pulsing. It only pulsed when the vent was closed at 75-90% intake air blockage.
It also blew hot ash 5 feet out the vent hole when pulsing. Pulse frequency about 3-5/second.
Anyway, I thought how handy that thing would be in colder climates for a fast warmup if you could control it and properly insulate it.
The pulsing action slammed the coals with air and sure nuff lit them up.
I can tell you exactly which stove I modified. It had a 12" pipe on the inside. Held water between the 12 and 16 inch pipe.
I torched out the 12 inch pipe to use for a regular wood stove.

Ah, looked up rocket stove toiv0. I get it. I understand why a steel version would be valuable.
That design gets max heat out of combustion and transfer and storage. Way superior design to a normal wood stove.
Allows heating cheap thermal mass, oh yea. Not sure UL would like it LOL, who gives a damn.
Looks like a good candidate for mass masonry or sand mass storage.
A ~3/16" thick steel replacement for the 55 gallon drum would be costly...un-galvinized corrugated drain pipe may do.
Would be concerned about rusting out in bottom section, and lots of heat down there. How to clean out ashes ??
