[Stoves] Jatropha press cake as a fuel Was: History of the KAKUTE plant oil stove

Thu Sep 14 09:30:01 CDT 2006

Dear Jonathan and others,

I am very interested in the prospects of Jatropha press cake as a fuel.

The T-LUD gasifiers use small pieces (such as small briquettes or enlarged
pellets or "tablettes" or chunks) as their preferred fuels.  Therefore, the
press cake of Jatropha and of other seed crops might make appropriate fuel as:

1.  directly made, 100% press cake,
2.  binder to hold together other agro-wastes and sawdust,
3.  ingredient that requires other binder to hold it together.

Where do we find info about the "burnability" of this and other press cake?

Where can we get some small samples?

Who has access and interest in doing this?

Paul
