How did you reduce/eliminate the "post barrel plenum" restriction? See the Helpful Hint thread for details of what I'm referring to. Pinhead, Let me answer that, if I may. There's lots of space around the riser because it's made of vermiculite board of 1" thick. Furthermore, the barrel is only supported along the rim. The base below the drum is wide open so there should be absolutely no difficulties regarding the manifold. @donkey, Yes, you are right, it's a rendering.

Very nice work! I think the fact that your company is making a commercial version of the rocket stove is a huge validation of the rocket stove principle, and the hard work Peter and others have put into it.
Please tell us about your company. Where is it located? Is there a web site? Have you received any "agency approvals" on the stove? Best of luck with your venture. Pete

Ok, i will say it...
I am REALLY happy for this rocket stove "launch" :-) And believe me, i REALLY am! But since the first time that i looked at it and then each time that i checked this thread i always get an association regarding the outer look of it. And i would be very surprised if i am the only one! Well i will say it now... It reminds me of a toilet.
Please, no hard feelings! It really is not my intention to insult anyone/anything.

No! - it reminds me of K9 the robot dog from Dr Who.

Maybe a Tom Baker / Dr. Who scarf would dress it up a bit. A more traditional looking model, possibly with a cast iron insert on top for the requisite tea kettle would be nice.
Dispite the comments from us art critics, it's great to see that it will be on the market - hopfully soon.
NOW would you please tell us about your company. Pete

Is the vertical feed tube required, or can an angled one work so feeding can slide in better

Hmm, $2,100 I'm obviously in the wrong business.

Steel fabrication is very expensive, i don't the price is all that bad, but I can not tell if the burn tunnel and riser are steel as well.

A little about our company... I used to do software and training in the computer world. 2007, we decided we need to re-tool so I went back to my roots. My background is an MS from Washington University School of Engineering. My thesis in 1982 (cringe) was in alternative fuel sources for developing countries using native oil seeds. So rocket heaters were a natural fit.
We are a small company, 3 employees. We actually make the molds and cast the products in house at our little factory.
These molds have been very, very hard to make. The positive is quite complex, finding the right material to cast a mold that is flexible enough to deal with the undercuts of the trip wires, and just their shear size makes pouring a challenge not to mention expensive. Every failed attempt in material or method is a long day and several hundred dollars in material.
But at long last, we think we are close, we have 6 molds and the 8 molds should be ready by next week.

Roll out plan is to off the engine cores 1st in 3 sizes. Due to the high cost of metal fabrication we have decide to go for a a kit to make a complete stove, square shaped, (no toilet look) with a bells under the burn tunnel. Something like the attachment. I am terrible with sketch up, but you get the idea. The kit has all the tricky metal pieces done, the top for the feed tube, the barrel mounting, and the exhaust connections. User's can then skin it however they like, using glass tile, stacked stone or simply painted skins. The thermal mass for the bell can be supplied by standard firebricks. Attachments:
