Pellet Burning Attachment (gravity feed) for Rocket Stove

I built this stove 10 years ago. The exterior and built in heat riser are still working.
I built a pellet burning attachment (gravity feeding) for rocket stove and fired up the stove this winter. It burned very well and was comfortable. It has been a while since I made a video of the rocket stove. Please take a look.
I was very inspired by Liberator Rocket Heaters. Thanks !
