[Stoves] Would anyone out there help turn coffee husks into some useful renewable energy source in Karagwe, tanzania?

[Tom Miles]

Joseph,

In addition to the suggestion by Richard Stanley to make fuel briquettes the
coffee waste could probably be burned in a bulk feeding stove with a sloped
grate like our old sawdust heating stoves. Larry Winiarski at Aprovecho has
built these combustors for rice husks and manure. The user would probably
have to shake the grate once in a while. See picture of the self feeding
Chumal ETHOS 2005.

Roger Samson, Would the Mayon Turbo work for coffee husks?
