@apples13able Actually it doesn't burn a lot. But i wouldn't leave it unattended for more than 10 min. I really wouldn't recommend one if you really have to heat a place, though. It really is too small. This is just some experiment with those type of stove. And Rocket Mass Heaters are really hard to tweak, as there are some critical points you have to respect, and not be too greedy on he heat you want to keep, otherwise it just won't work.
@apples13able Yes, but you would have to wiggle it, to break the long ember it would sit on every 5-10 minutes. This shaking allows the wood to be surrounded by embers and achieve a complete pyrolisis, whereas when left it would just die out, as the wood wouldn't be heated thouroughly to release gases.
@Rhinoch8 Guess you would need a shaker like on the hopper of a wood gasifier... maybe hooked up to a motor or maybe a palm sander... to be automatic like anyway... Bigger rocket stove setups can accept bigger logs and would have longer burn times because of that, plus they can extract most of the heat if the exhaust is run thru thermal mass of a cob bench or whatever... so you could let it burn out and the thermal mass would slowly release the heat. I still wanna bild yr stove and play with it.
@apples13able Yeah have a try! But i would be careful with puttin big logs into RMH, as the interstice where the air goes through the combustible are smaller. I had issues in the best of my RMH of flamebacks when putting big logs, even with the best insulation i could imagine, and without the mass sucking heat. I shall post 2 more videos about my portable RMH (which was a failure, as i believe there is a critical mass as the chamber width), and the huge RMH core i built which had flamebacks
@nwsisu Hehe thanks! But in a way, this is already the most lightweight version! Check out paulwheaton12 Rocket Mass Heater, i took the inspiration from his work.
How long can you leave it before refueling? I wonder what the longest stick is you could use for fuel? Awesome stove! Simple, cheap and effective!

@Rhinoch8 Looks fun to play with tho. If you put a meter long stick in, would it burn uninterrupted?

how do you get the ash out?

@billhemingway With a kind of spoon i fashioned with a can of beans. It's not a hassle, most of the ashes just fly off through the flue pipe.

That IS cool! I should try this technique. Maybe a light weight version, though
