[Gasification] Gasification and Water Injection into producergas

[Peter Wilson]

Unfortunately I don't. I run a very small scale biodiesel operation myself,
so I contacted the company out of interest to find out more, only I haven't
received any replies. I imagine that they are keeping everything quiet until
they get their plant going on a commercial basis.
