[Stoves] Coffee waste and briquettes

Tue Dec 19 20:49:58 CST 2017

James,

I suggest that your consider pelletizing the coffee husks.   Results of 
a search:  (sorry for the format of the display.)

And use pellets in the forced-air TLUDs like the FAABulous stove from 
South Africa.   You get the pellets and the stoves will do the rest.
