RE: GAS-L: Oh!! -- that small steam power plant ---

[Mike Norris <mnorris@dekaresearch.com>]

What is the experience with using Jatropha oil in burners.  I've heard
it has bad coking (tar) problems that clog injectors.  Any experience
or comments.  Also does anyone know where I could get  Jatropha oil
for some experiments.
