This is an addendum to this post The Overnight Tent Stove. The self-fueling tube works!
Proof of concept: A 2″ x 8″ plastic tube filled with approx 1 cm gum pellets. Approx 1 gram of wood per 1 mm of height so I could just about fit 1.5 metres in my Grey Flyer Tent which would be roughly 1.5 kg or just under 4 hours burn time.
Will they feed out without jamming? Yes:
