Art,
At various times we have seen examples of corn cob use in rocket stoves at ETHOS by Trees Water and People (Honduras) and CEDESOL (Bolivia, David Whitfield ) http://www.treeswaterpeople.org/ http://cedesol.org/ Volunteer from various organizations have told me that people often push cobs in along with wood fuel.

I have often seen this in both Costa Rica and the US. We have not encountered anyone in Costa Rica's indigenous reserves using corn cobs as a fuel source, but there is no scarcity of woody biomass in these areas. I did a quick look online and saw that using approximately 20% corn cobs in the diet of pigs is a practice that has a long history and has often been promoted by various extension services and researchers. As I said, we know they work great in the TLUDs, but have not yet worked in an area where they are widely enough available to make them a cooking fuel option. Art Donnelly
