Mr Switchgrass is an inverted downdraft gasifier design that burns/gasifiers chopped switchgrass or weeds with little to no smoke problems. A rule of thumb is that each section will burn for a solid ten minutes at full flame. I measured 66 lbs for one load and it ran for about 40 to 50 minutes.

Burner Flame

Burn Flame 2: Started with paper or house trash.

Burn Flame 3: Smoke free flame.

Burn Flame 4

Burn Flame 5: Very clean burn.

Bale Storage: This is how I stored the bales of switchgrass.

Flue: No smoke from the stack.

Transformation Tower: More proof of the clean burn.

Air tube and grate: Grate and air tube.

Loaded: Here you can see a new load of switchgrass, air tube and air holes.
