Someone in Norway is making these wood stoves and installing them in mountain cabins. Gotta be efficient in such frigid conditions !! They are more like sculptures. Look very efficient due to the large top surface. Thought I would make a similar smaller sized 36" unit. (copycatting, don't tell) I do have the same larger metal components here in stock as the Norwegians used. This is a smaller prototype for testing the air flow and heat output. It can also serve as heavy cover that can be set down on an existing fire pit by 2 people using handles. Great for windy days and puts out incredible heat even when burning green wood. It actually makes a fine enclosed wood stove when using adjustable air controls, sipping wood slowly. Holds a crap load of wood. Sexy Norwegian version: firepitsatlanta rough hamburger prototype: With smoke rising above participants - yeah!!! : Had several brainstorms regarding applications of this thing. 1) Is able to have a form built around it and poured over with concrete to make a large thermal mass burner.(think pizza oven) Easily structurally strong enough to handle the concrete. It is cheap thermal mass... 2) A 48" or 54" unit with adjustable air vents for burning manageable 3' to 4' long stick wood say 2 to 6 inches in diameter like cut from young trees. The long wood slides in to the loading hole easily. It should burn for 24 to 72 hours IMO since it can burn slow with air intake set low and has such a large capacity. 3) Sold as an accessory cover for metal bowl type outdoor fire pits.

Put a flat top in the middle so I can use it as a Mongolian grill and fry eggs..

Has to be special concrete like the rocket stoves to take the heat.

I like the chimney modification you posted on FB.
Yes, the cook stove conversion would be a great option.

Add water pipes to distribute the heat around the room.

Yes! Like that the smoke doesn't get those sitting around the fire. Smoke hurts my eyes, but otherwise, I like sitting around fires.

Similar style on This Old House last season, except it was a wall-hung gas unit. Close enough for horseshoes?

Pat rockjunquie You guys are so very correct. That smoke makes for a miserable experience. If it were possible to install a smoke vent AND have an open air fire we'd become millionaires. This 'jet engine' fire pit was smokeless but ate like a medium whole tree every hour.

Has to be special concrete like the rocket stoves to take the heat. It needs some pins welded to it to receive a flat cook top Billy. I think they call it refractory cement made out of high content aluminum oxide clay(kaolin). Same clay potters use on their kilns. Probably expensive. Maybe you know a good loose rock to use like granite or gneiss to cover it with... Cobbles best ?

Add water pipes to distribute the heat around the room. It was raising the garden hose water to about 120F in the amount of time it was pouring over the top. Yes, a mean water heater. Amish wood fired water heater, simply a pipe in a pipe with 2 end flanges. Made one before and it worked fine.

Seen these at campgrounds around the Southeast. People are using a washing machine drum as a burner. Flames shoot straight up and smoke no problem. Eats wood up very fast.

The 36 inch unit at start of this thread makes such an efficient -wood stove- I thought I would try a smaller 30 inch unit. These 30 inch bowls are just stuck together to test fit, not welded. The deep bowl is an LP gas tank end and the silver bowl is a lower pressure rated air compressor tank end. It will still hold a crap load of fire wood. BUT, has to have air vent/door and exhaust welded to it. tested for draw and smoke removal. The Acorn

You can get 10-12 feet away from these when they're glowing red and still feel plenty of heat over a large area.
