Good design from what I can tell from a mfr perspective. Well that is till at the 2:00 mark you see a special type of pot required. There is probably a design reason for the shaping. But from a mfr local production angle that is not the right direction.
I made this one after seeing how popular the basic block rockets and cook stoves were online. However this one I wanted to make a vertical gravity fed J-tube style, unlike any I've ever seen before as far as the block rockets go.
I am confused, I think this is not actually a smokeless burn, it filters more of the smoke/creosote into the filters, and lets you clean it by cleaning the chimney, and helps you do that safely. But I don't see that it actually burns the smoke. Given that they say you have to clean the chimney, I'm assuming that there is creosote buildup. But I don't know enough about this to know what temperatures its working at or how much the "filtering" really does for the outdoor air. Can you fill us in, Big Al?
It seems the focus is on moving the smoke out of people's houses through the chimney. This is a good step, and essential to preserve human health in the immediate, but if the overall problem of particulate emissions is still very grave for humans and ecosystems (as people in the UK seem to be adamant about, especially in densely populated areas) then this design seems to me to be a step down from the original tin can Appropedia design as far as the total, long-term particulate emissions impact on humans outdoor breathing air and the ecosystem.
Again, I am still quite new to this, but maybe others have the same questions.
What do you find most beneficial about this design?
