Rocket stove heater with vortex drafting.

I like the ideal, but what do you think of increasing the size of the fire box to allow for more wood and a longer burn time. I’m looking for a 12 hour burn time. Thanks

I do like the idea, for a small space however this is just right.
This will heat 300 square feet no problem.
The stove can be scaled up to handle that kind of load and it will put out a great deal of heat, I would suspect some areas would have to be beefed up due to the larger volume of combustion.

I saw ppotty1 on youtube making vortex rocket
starting making today ,i want to make four using 6 inch risers any tips? or improvements
