Crispin,

I'm located in the US (Colorado).  We're actually having difficulties
importing seedcake from Guatemala, where our research is being conducted.
 To the best of my knowledge, the closest source of Jatropha seedcake would
be Diligent Tanzania <http://www.diligent-tanzania.com/index.php?id=1112> (
jan at diligent-tanzania.com or ruud.van.eck at diligent.nl), who are currently
trying to briquette the material with an automatic press.

It sounds like Dr. Anderson has found a way to burn the seeds, which is most
excellent, but it would also be beneficial to burn the waste material after
the oil extraction process.  Maybe with a similar TLUD?  As you
know, Jatropha projects are springing up everywhere, so it could be very
influential...

Cheers,
Boston
