    Planned obsolescence. If you make a product that lasts a lifetime you most likely will be approached with an offer so the buyer can cheap down everything and soak up a bunch of money. No character anymore, just money.

    Several things to add: there's to be certain height of chimney tube for max efficacy: the afterburner effect for the flammable volatile products of wood pyrolysis, which are burnt while acsending. For 100 mm diameter chimney, it's to be at least 600(!) mm height. Secondary contour as small holes in chimney additionally deliver air for more complete combustion, reducing height for 6-8%. Also, the horizontal feeding tube doesn't allow wood to drop by it's weight into the combustion area. Though these stoves are for cooking seemingly - size and flame! "Perfect" rocket stove works by heated gases only, however they may get to 1000*C = 1832*F!

    Great video and good explanation of the basics. I like the idea of using angle iron in order to ensure the airflow isn't blocked. I guess the same is achieved by adding a 45 degrees tube or pipe as fuel feeder, which leaves the horizontal arm free for intake of air. Another idea would be to add a small grill at the point where the three tubes meet, and underneath add a sliding pan with its own opening that collects the ash, and can be removed even when the fire is still going, and emptied. I'll know more as soon as I've tried to build one myself. Regards.

    Thanks for the great video. Good explanation of the combustion issues and I like your flame maintenance slot in the fuel stick tray and classy welding. Keep exploring. I make tiny light (SS or titanium foil) Aussie stoves for alpine backpacking (described in the links below). They are kind of 'rockety' but, at as little as 500g weight, they don't qualify fully because they have no heat riser (metal, ceramic, round, square or otherwise). However, they have ceramic lining in the hottest parts (to retain heat for initial combustion and protect the metal) and have 'J-style' fuel stick feeders that let the sticks feed themselves into the pyrolysis chamber that naturally regulates the amount of fuel that can be pyrolysed at any time (like yours). The steady plume of wood gas completes its combustion, in the stove box/cooktop/ heater, having passed through a bed of glowing charcoal and air mixing is aided by rapid changes of direction of gas flow within the stove box. The combustion is very clean and efficient (only~400g/hr with no significant smoke or any sparks from the flue pipe). Most of the air enters between the sticks (no separate air path as in yours) and the stove makes a quiet chuffing sound which I think results from the burn rate pulsating during the natural self regulation process. As in your stove, ash builds up at the bottom of the J-tube and restricts the burn chamber volume, but it is slow to accumulate and can be pushed out of the way into the stove box. The useful heat output is from the stove box inside the tent. I view them as regulated smoke generators that burn the smoke completely. I would be interested in your comments and if you think I have a correct understanding of the combustion process. timtinker.com/ultralight-tent-stove-part-2/ timtinker.com/larger-ultralight-tent-stove/ Tim

    Great welds. If you cut into the side of your pipe where the upright pice is ten to twenty m.m. below the wood insert pipe you have a place for your ash. Also if you put it on a cinder block it will be taller and a small metal can in cinder block is easy to remove and dump.

    Most wood stoves exibit the aspects of a rocket stove when their first lit, especially when leaving the door slightly open as the wood starts to light off, and it starts to roar like a rocket,but its impractical to run a wood stove at that level, as the wood consumption would be very high as well as the heat output.

    VERY nice build quality. You could use them as axle stands when you aren't brewing a cuppa...! when I was 11 I now realise I made basically what was a rocket stove (or furnace actually it was that imposing!) The bottom section (horizontal) was made of bricks fastened with clay, the chimney was made from a 3 foot section of steel gate post about 4 x 3 inches.That thing was scary it roared so much and was red hot at times great big blue/orange flame shooting out the top I read somewhere about the designers of high performance steam trains, they uused a secondary burning chamber for better fuel efficiency. I think some top range woodburning stoves use the same principle, recirculate and burn the smoke
